Der Komet - Astronomie und Raumfahrt: aktuelle Beiträge
Dezember werden wir in Deutschland verpassen. Somit dürften die Ellipsen vorherrschend sein.
Prior to being sent on the Northern Sea Route, the Komet was equipped with a specially strengthened bow and a propeller suitable for navigating through ice.
With the consent of the then supposedly neutral Soviet Union, Komet initially made her way along the Norwegian coast disguised as the Soviet icebreaker Semyon Dezhnev.
After a conference on strategy, the three captains decided to work together, concentrating on the New Zealand to Panama passage taken by most of the Allied merchant ships.
Together with the other two ships, on 25 November she sunk the coaster Holmwood [1] and two days later the passenger liner Rangitane , raiding her precious food load.
During December, Komet and Orion casually [12] met and sunk in the waters surrounding Nauru Island five Allied merchant ships , with a combined tonnage of about 41, tons, that had been waiting off the island to load phosphate of which Komet sank three.
At the end of December Eyssen planned to lay a minefield at the entrance of the Rabaul 's harbour. He was forced to abandon his plan due to an engine failure on the Meteorit boat that was designed for the mission.
The bad weather though convinced Eyssen to change his plans into a direct attack to the island infrastructures.
On 27 December the Komet sent a warning to the island and announced that the attack was about to begin. She shelled and heavily damaged the loading plants and mooring buoys of the port.
The bombing lasted an hour, and it caused the loss of 13, tons of oil. After the Nauru attack probably the major German success in the pacific operational area during the war the Komet received the order to set a new course towards south, crossing the Indian Ocean and scouting the presence of Allied whalers.
The hunt for allied ships in the Indian Ocean had no success; after some months, Eyssen sailed towards the Panama Canal , hoping to find more convoys in the Pan-American Security Zone , recently opened to military actions from the Kriegsmarine high command.
On 19 August Komet met the freighter Devon and sank it. After these three successes, Eyssen decided to move out of the area, fearful of the reaction of the Allied navy.
Komet headed towards New Zealand accompanied by the captured Kota Nopan. At the end of September she had a brief meeting with the auxiliary cruiser Atlantis [26] and transferred to her a part of the prisoners and cargo load [27].
Komet then received the order to return to Germany. The ship set a new course towards Cape Horn , sailing at a slower speed in the Atlantic Ocean disguised as the Portuguese freighter S.
Komet reached the French port of Cherbourg on 26 November, [1] disguised as the freighter Sperrbrecher The day after she had a short stop in Le Havre and then sailed towards Germany.
Some British torpedo bombers spotted her in the English Channel but were not able to sink her. The ship had sunk seven ships two in conjunction with the raider Orion for a total of 41, tons.
The Komet was prepared for a second raiding voyage in October , after 11 months of complete repair. Only two of her original officers had remained on board and Kapitän zur See Ulrich Brocksien took over command.
On 7 October the raider, disguised as a minesweeper , departed from the Dutch-occupied port of Vlissingen with the objective to reach the Atlantic Ocean.
Initial attempts by the Royal Navy to attack the ship in the Straits of Dover had failed. On 13 October, Komet sailed from Le Havre with an escort of 4 or 5 torpedo boats.
These 3 groups headed for a position near Cap de la Hague. The German convoy were spotted by a Coastal Command aircraft in the middle of the Baie de la Seine , travelling at 16 knots, and groups A C and D hurried to get into position.
In the particularly dark night and moderately rough sea conditions, the MTB flotillas became separated from the destroyers.
At just before am, Cottesmore sighted the German vessels. The allied ships fired star shells to illuminate the target and then opened fire. To the British attackers, the Germans appeared taken completely by surprise and in the confusion, opened fire on each other, until eventually firing torpedoes at the allied ships all of which missed.
Two of the escorts were on fire and the other German ships turned inshore to gain the protection of the coastal artillery batteries.
As junior, Drayson was last in the line of MTBs and became separated from the rest of the flotilla as they crossed the Channel. Drayson continued independently to Cap de La Hague.
None of the other allied MTBs arrived in the area. After a while, Drayson saw star shells and tracer as the battle started and increased speed.
He decided to approach the action from the shoreward side to catch any German vessel trying to get away. This put MTB in position to see Komet illuminated by a star shell.
The German ship was travelling at more than 15 knots, exchanging fire with the allied destroyers who were in pursuit.
Drayson's MTB was ahead of the German ship and crept in at slow speed to fire 2 torpedoes at a range of yards. MTB immediately turned away and "crash-started" her main engines to escape under cover of a smoke-screen.
Komet had now sighted her and switched fire. Within a few seconds, the 2 torpedoes struck, followed by a huge secondary explosion. The force of this blast lifted the stern of MTB out of the water and put out of action 2 of the boat's 3 engines, leaving her to return home at reduced speed.
Group B had moved to join the battle and engaged some of the remaining German vessels, but with the main target gone and shore battery fire now becoming more accurate, broke off the action and returned home.
In the Me B and -C subtypes, a ram-air turbine on the extreme nose of the fuselage, and the backup lead-acid battery inside the fuselage that it charged, provided the electrical power for the radio, the Revi16B, -C, or -D reflector gunsight , the direction finder , the compass, the firing circuits of the cannon, and some of the lighting in the cockpit instrumentation.
The airspeed indicator averaged readings from two sources: the pitot tube on the leading edge of the port wing, and a small pitot inlet in the nose, just above the top edge of the underskid channel.
The resistance group around the later executed Austrian priest Heinrich Maier had contacts with the Heinkelwerke in Jenbach in Tyrol, where important components for the Messerschmitt Me were also produced.
The group passed on relevant information to the Allies. With the location sketches of the production facilities, the Allied bombers were able to carry out targeted air strikes.
In early production of a prototype series, known as the Me , began. Three Bf prototypes VV3 were built. It was thought that intelligence services would conclude any reference to the number "" would be for that earlier design.
Ten Me As V4-V13 were built for pilot training and further tests. During testing of the prototype A-series aircraft, the jettisonable undercarriage presented a serious problem.
The original dollies possessed well-sprung independent suspension for each wheel, [16] and as the aircraft took off, the large springs rebounded and threw the dolly upward, striking the aircraft.
The production B-series aircraft used much simpler, crossbeam-axled dollies, and relied on the landing skid's oleo-pneumatic strut [17] to absorb ground-running impacts during the takeoff run, as well as to absorb the shock of landing.
If the hydraulic cylinder was malfunctioning, or the skid mistakenly left during a landing procedure in the "locked and lowered" position as it had to be for takeoff , the impact of a hard touchdown on the skid could cause back injuries to the pilot.
Once on the ground, the aircraft had to be retrieved by a Scheuch-Schlepper , a converted small agricultural vehicle, [19] originally based on the concept of the two-wheel tractor , carrying a detachable third swiveling wheel at the extreme rear of its design for stability in normal use—this swiveling third wheel was replaced with a pivoting, special retrieval trailer that rolled on a pair of short, triple-wheeled continuous track setups one per side for military service wherever the Komet was based.
This retrieval trailer usually possessed twin trailing lifting arms, that lifted the stationary aircraft off the ground from under each wing whenever it was not already on its twin-wheel dolly main gear, as when the aircraft had landed on its ventral skid and tailwheel after a mission.
During flight testing, the superior gliding capability of the Komet proved detrimental to safe landing. As the now un-powered aircraft completed its final descent, it could rise back into the air with the slightest updraft.
Since the approach was unpowered, there was no opportunity to make another landing pass. For production models, a set of landing flaps allowed somewhat more controlled landings.
This issue remained a problem throughout the program. Development of an operational version was given the highest priority.
In December , work on an upgraded design began. A simplified construction format for the airframe was deemed necessary, as the Me A version was not truly optimized for large-scale production.
The result was the Me B subtype, which had the desired, more mass-producible fuselage, wing panel, retractable landing skid and tailwheel designs with the previously mentioned unsprung dolly takeoff gear, and a generally one-piece conical nose for the forward fuselage which could incorporate a turbine for supplementary electrical power while in flight, as well as a one-piece, perimeter frame-only hinged canopy [ clarification needed ] for ease of production.
Meanwhile, Walter had started work on the newer HWK bipropellant hot engine , which added a true fuel of hydrazine hydrate and methanol , designated C-Stoff , that burned with the oxygen-rich exhaust from the T-Stoff , used as the oxidizer, for added thrust see: List of Stoffs.
The new powerplant and numerous detail design changes meant to simplify production over the general A-series airframe design resulted in the significantly modified Me B of late Due to the Reichsluftfahrtministerium requirement that it should be possible to throttle the engine, the original power plant grew complicated and lost reliability.
The fuel system was particularly troublesome, as leaks incurred during hard landings easily caused fires and explosions. Metal fuel lines and fittings, which failed in unpredictable ways, were used as this was the best technology available.
Both fuel and oxidizer were toxic and required extreme care when loading in the aircraft, yet there were occasions when Komets exploded on the tarmac from the propellants' hypergolic nature.
For safety purposes, it left the immediate area of the aircraft following its delivery and capping off of the Komet ' s fuel tanks from a rear located dorsal fuselage filling point just ahead of the Komet ' s vertical stabilizer.
Then, the other tanker truck carrying the very reactive T-Stoff hydrogen peroxide oxidizer would deliver its load through a different filling point on the Komet ' s dorsal fuselage surface, located not far behind the rear edge of the canopy.
The corrosive nature of the liquids, especially for the T-Stoff oxidizer, required special protective gear for the pilots.
To help prevent explosions, the engine and the propellant storage and delivery systems were frequently and thoroughly hosed down and flushed with water run through the propellant tanks and the rocket engine's propellant systems before and after flights, to clean out any remnants.
Early in the war, when German aircraft firms created versions of their aircraft for export purposes, the a was added to export ausland variants B-1a or to foreign-built variants Ba-1 but for the Me , there were neither export nor a foreign-built version.
As the Me was planned with [29] an alternative BMW PA rocket engine, it is likely the "a" was used for this purpose on early examples. Only one Me , the V10, was tested with the BMW engine, so this designation suffix was soon dropped.
The Me B had very docile landing characteristics, mostly due to its integrated leading edge slots , located directly forward of the elevon control surfaces, and just behind and at the same angle as the wing's leading edge.
It would neither stall nor spin. One could fly the Komet with the stick full back, and have it in a turn and then use the rudder to take it out of the turn, and not fear it snapping into a spin.
It would also slip well. Because the Me B's airframe design was derived from glider design concepts, it had excellent gliding qualities, and the tendency to continue flying above the ground due to ground effect.
On the other hand, making a too close turn from base onto final, the sink rate would increase, and one could quickly lose altitude and come in short.
Another main difference from a propeller-driven aircraft is that there was no slipstream over the rudder. Pilots accustomed to flying propeller-driven aircraft had to be careful that the control stick was not somewhere in the corner when the control surfaces began working.
These, like many other specific Me problems, would be resolved by specific training. The performance of the Me far exceeded that of contemporary piston engine fighters.
The usable Mach number was similar to that of the Me , but because of the high thrust-to-drag ratio, it was much easier for the pilot to lose track of the onset of severe compressibility and risk loss of control.
A Mach warning system was installed as a result. The aircraft was remarkably agile and docile to fly at high speed.
According to Rudolf Opitz, chief test pilot of the Me , it could "fly circles around any other fighter of its time".
By this point, Messerschmitt was completely overloaded with production of the Messerschmitt Bf and attempts to bring the Me into service.
Production in a dispersed network was handed over to Klemm, but quality control problems were such that the work was later given to Junkers, who were, at that time, underworked.
As with many German designs of World War II's later years, parts of the airframe especially the wings were made of wood by furniture manufacturers.
The older Me A and first Me B prototypes were used for training. It was planned to introduce the Me S , which removed the rocket engine and tank capacity and placed a second seat for the instructor above and behind the pilot, with his own canopy.
The Me S would be used for glider landing training, which as explained above, was essential to operate the Me It appears the Ss were converted from the earlier Me B series prototypes.
In service, the Me turned out to be difficult to use against enemy aircraft. Its tremendous speed and climb rate meant a target was reached and passed in a matter of seconds.
Although the Me was a stable gun platform, it required excellent marksmanship to bring down an enemy bomber.
Four or five hits were typically needed to take down a B Innovative methods were employed to help pilots achieve kills. The most promising was a weapon called the Sondergerät Jägerfaust.
Five were mounted in the wing roots on each side of the aircraft. A photocell in the upper surface of the Komet triggered the weapons by detecting the change in brightness when the aircraft flew under a bomber.
As each shell shot upwards, the disposable gun barrel that fired it was ejected downwards, thus making the weapon recoilless. It appears that this weapon was used in combat only once, resulting in the destruction of a Lancaster bomber on 10 April The biggest concern about the design was the short flight time, which never met the projections made by Walter.
With only seven and a half minutes of powered flight, the fighter truly was a dedicated point defense interceptor. To improve this, the Walter firm began developing two more advanced versions of the A rocket engine, the B and C, each with two separate combustion chambers of differing sizes, one above the other, for greater efficiency.
They were tuned for high power for takeoff and climb. Two Bs, models V6 and V18, were experimentally fitted with the lower-thrust B-version of the new twin-chamber engine mandating twin combustion chamber pressure gauges on the instrument panel [40] of any Komet equipped with them , a retractable tailwheel, and tested in spring The main combustion chamber of the B engine used for the B V6 and V18 occupied the same location as the A-series' engine did, with the lower Marschofen cruise chamber housed within the retractable tailwheel's appropriately widened ventral tail fairing.
The X-1 never exceeded Dittmar's speed from a normal runway " scharfer Start " liftoff. Waldemar Voigt of Messerschmitt's Oberammergau project and development offices started a redesign of the to incorporate the new twin-chamber Walter rocket engine, as well as fix other problems.
The resulting Me C design featured a larger wing through the addition of an insert at the wing root, an extended fuselage with extra tank capacity through the addition of a plug insert behind the wing, a ventral fairing whose aft section possessed a retractable tailwheel design closely resembling that pioneered on the Me B V6, and a new pressurized cockpit topped with a bubble canopy for improved visibility, on a fuselage that had dispensed with the earlier B-version's dorsal fairing.
By this time the project was moved to Junkers. There, a new design effort under the direction of Heinrich Hertel at Dessau attempted to improve the Komet.
The Hertel team had to compete with the Lippisch team and their Me C. Hertel investigated the Me and found it was not well suited for mass production and not optimized as a fighter aircraft, with the most glaring deficiency being the lack of retractable landing gear.
To accommodate this, what would eventually become the Me V1 prototype would be fitted with the desired tricycle gear, also accommodating the twin-chamber Walter rocket from the start—later it was assigned to the Ju program.
The resulting Junkers Ju used a three-section fuselage to ease construction. The V1 prototype was completed for testing in August , and was glider-tested behind a Junkers Ju Some sources state that the Walter —C engine was fitted in September, but it was probably never tested under power.
This appears to have been a formality only, with Junkers continuing the work and planning production.
While it did not reach operational status, the work was briefly continued by the Soviet Mikoyan-Gurevich MiG design bureau as the Mikoyan-Gurevich I The initial test deployment of the Me A, to acquaint prospective pilots with the world's first rocket-powered fighter, occurred with Erprobungskommando 16 Service Test Unit 16, EK 16 , led by Major Wolfgang Späte and first established in late , receiving their eight A-model service test aircraft by July Their initial base was as the Erprobungsstelle test facility at the Peenemünde-West field.
They departed permanently the day after an RAF bombing raid on the area on 17 August , moving southwards, to the base at Anklam , near the Baltic coast.
Their stay was brief, as a few weeks later they were placed in northwest Germany, based at the military airfield at Bad Zwischenahn from August to August As EK 16 commenced small-scale combat operations with the Me B in May , the Me B's unsurpassed velocity was something Allied fighter pilots were at a loss to counter.
The Komets attacked singly or in pairs, often even faster than the intercepting fighters could dive. This approach afforded the pilot two brief chances to fire a few rounds from his cannons before gliding back to his airfield.
The pilots reported it was possible to make four passes on a bomber, but only if it was flying alone. Pilots underwent altitude chamber training to harden them against the rigors of operating in the thin air of the stratosphere without a pressure suit.
Special low fiber diets were prepared for pilots, as gas in the gastrointestinal tract would expand rapidly during ascent. JG 's purpose was to provide additional protection for the Leuna synthetic gasoline works which were raided frequently during almost all of A further group was stationed at Stargard near Stettin to protect the large synthetic fuel plant at Pölitz today Police, Poland.
Further defensive units of rocket fighters were planned for Berlin , the Ruhr and the German Bight. The first actions involving the Me B in regular Luftwaffe active service occurred on 28 July , from I.
Combat operations continued from May to spring During this time, there were nine confirmed kills with 14 Me s lost. Feldwebel Siegfried Schubert was the most successful pilot, with three bombers to his credit.
They would wait and, when the engine exhausted its propellant, pounce on the unpowered Komet. However, the Komet was extremely manoeuvrable in gliding flight.
Another Allied method was to attack the fields the Komets operated from and strafe them after the Me s landed.
Due to the skid-based landing gear system, the Komet was immobile until the Scheuch-Schlepper tractor could back the trailer up to the nose of the aircraft, place its two rear arms under the wing panels, and jack up the trailer's arms to hoist the aircraft off the ground or place it back on its take-off dolly to tow it back to its maintenance area.
At the end of , 91 aircraft had been delivered to JG but lack of fuel had kept most of them grounded. It was clear that the original plan for a huge network of Me bases would never be realized.
Up to that point, JG had lost only six aircraft due to enemy action. Nine were lost to other causes, remarkably few for such a revolutionary and technically advanced aircraft.
In the last days of the Third Reich , the Me was given up in favor of the more successful Me At the beginning of May , Me operations were stopped, the JG disbanded, and many of its pilots sent to fly Me s.
In any operational sense, the Komet was a failure. Although it shot down 16 aircraft, mainly four-engined bombers, it did not warrant the effort put into the project.
Due to fuel shortages late in the war, few went into combat, and it took an experienced pilot with excellent shooting skills to achieve "kills".
The Komet also spawned later weapons like the vertical-launch, similarly rocket-powered Bachem Ba Natter , and the postwar, American turbojet-powered Convair XF delta wing interceptor.
Ultimately, the point defense role that the Me played would be taken over by the surface-to-air missile SAM , Messerschmitt's own example being the Enzian.
On around 17 May , he flew an Me B at Husum with the help of a cooperative German ground crew, after initial towed flights in an Me A to familiarise himself with the handling.
The day before the flight, Brown and his ground crew had performed an engine run on the chosen Me B to ensure that everything was running correctly, the German crew being apprehensive should an accident befall Brown, until being given a disclaimer signed by him to the effect that they were acting under his orders.
During the flight, while practicing attacking passes at an imaginary bomber, he was surprised at how well the Komet accelerated in the dive with the engine shut down.
Once down safely, Brown and his much-relieved ground crew celebrated with a drink. Beyond Brown's unauthorised flight, the British never tested the Me under power themselves; due to the danger of its hypergolic propellants it was only flown unpowered.
Brown himself piloted RAE's Komet VF on a number of occasions, the rocket motor being replaced with test instrumentation.
When interviewed for a s television programme, Brown said he had flown five tailless aircraft which did not include the pair of American Northrop X-4s in his career including the British de Havilland DH Referring to the Komet, he said "this is the only one that had good flight characteristics"; he called the other four "killers".
It has been claimed that at least 29 Komets were shipped out of Germany after the war and that of those at least 10 have been known to survive the war to be put on display in museums around the world.
According to the RAF museum, 48 aircraft were captured intact and 24 were shipped to the United Kingdom for evaluation, although only one, VF , was test flown unpowered.
Eventually an elderly German woman came forward with Me instruments that her late husband had collected after the war, and the engine was reproduced by a machine shop owned by Me enthusiast Reinhold Opitz.
The factory closed in the early s and "Yellow 25" was moved to a small museum created on the site. The museum contained aircraft that had once served as gate guards, monuments and other damaged aircraft previously located on the air base.

While it did not reach operational status, the work was briefly continued by the Soviet Mikoyan-Gurevich MiG design bureau as the Mikoyan-Gurevich I The initial test deployment of the Me A, to acquaint prospective pilots with the world's first rocket-powered fighter, occurred with Erprobungskommando 16 Service Test Unit 16, EK 16 , led by Major Wolfgang Späte and first established in late , receiving their eight A-model service test aircraft by July Their initial base was as the Erprobungsstelle test facility at the Peenemünde-West field.
They departed permanently the day after an RAF bombing raid on the area on 17 August , moving southwards, to the base at Anklam , near the Baltic coast.
Their stay was brief, as a few weeks later they were placed in northwest Germany, based at the military airfield at Bad Zwischenahn from August to August As EK 16 commenced small-scale combat operations with the Me B in May , the Me B's unsurpassed velocity was something Allied fighter pilots were at a loss to counter.
The Komets attacked singly or in pairs, often even faster than the intercepting fighters could dive. This approach afforded the pilot two brief chances to fire a few rounds from his cannons before gliding back to his airfield.
The pilots reported it was possible to make four passes on a bomber, but only if it was flying alone. Pilots underwent altitude chamber training to harden them against the rigors of operating in the thin air of the stratosphere without a pressure suit.
Special low fiber diets were prepared for pilots, as gas in the gastrointestinal tract would expand rapidly during ascent.
JG 's purpose was to provide additional protection for the Leuna synthetic gasoline works which were raided frequently during almost all of A further group was stationed at Stargard near Stettin to protect the large synthetic fuel plant at Pölitz today Police, Poland.
Further defensive units of rocket fighters were planned for Berlin , the Ruhr and the German Bight. The first actions involving the Me B in regular Luftwaffe active service occurred on 28 July , from I.
Combat operations continued from May to spring During this time, there were nine confirmed kills with 14 Me s lost.
Feldwebel Siegfried Schubert was the most successful pilot, with three bombers to his credit. They would wait and, when the engine exhausted its propellant, pounce on the unpowered Komet.
However, the Komet was extremely manoeuvrable in gliding flight. Another Allied method was to attack the fields the Komets operated from and strafe them after the Me s landed.
Arus debu dan gas yang dihasilkan membentuk suatu atmosfera yang besar tetapi sangat tipis di sekeliling komet, disebut 'koma'.
Akibat tekanan radiasi dan angin suria pada koma ini, terbentuklah ekor raksasa yang menjauhi matahari. Debu dan gas komet akan membentuk dua ekor yang berbeza, di mana ekor debu agak mengikut arah pergerakannya manakala ekor gas ion sentiasa menjauhi matahari.
Ini disebabkan oleh angin suria lebih mempengaruhi ion gas daripada debu. Saiz diameter nukleus bahagian pejal di tengah komet biasanya kurang dari 50 km.
Namun saiz koma yang mengelilingi nukleus boleh mencapai , km lebar. Ekor komet pula boleh mencapai lebih ,, km 1 AU panjang. Koma dan ekor komet membalikkan cahaya matahari dan boleh dilihat dari bumi jika komet itu cukup dekat.
Ekor komet berbeza-beza bentuk dan saiznya. Lebih dekat komet tersebut dengan matahari, lebih panjanglah ekornya. This put MTB in position to see Komet illuminated by a star shell.
The German ship was travelling at more than 15 knots, exchanging fire with the allied destroyers who were in pursuit.
Drayson's MTB was ahead of the German ship and crept in at slow speed to fire 2 torpedoes at a range of yards. MTB immediately turned away and "crash-started" her main engines to escape under cover of a smoke-screen.
Komet had now sighted her and switched fire. Within a few seconds, the 2 torpedoes struck, followed by a huge secondary explosion. The force of this blast lifted the stern of MTB out of the water and put out of action 2 of the boat's 3 engines, leaving her to return home at reduced speed.
Group B had moved to join the battle and engaged some of the remaining German vessels, but with the main target gone and shore battery fire now becoming more accurate, broke off the action and returned home.
Komet sank with no survivors. The allied forces experienced only 2 minor casualties, despite being under heavy fire.
She is in two halves and upside down, with a large part of the center section blown away by the explosion that sank her.
