""" HE-162 VARIANTS
* Heinkel built two He-162 prototypes fitted with the larger "Jumo-004D-4" engine, which was planned to lead to a "He-162A-8" version with higher performance and greater endurance. Heinkel also built two prototypes of the "He-162S" tandem-seat training glider, in accordance with the lunatic scheme to provide pilots for the fighter using Hitler Youth. No He-162A-3s, with the reinforced nose mounting twin MK-108 30 millimeter cannon, were ever produced.

* A number of advanced follow-ons to the He-162A were considered. An "He-162B-1" was slated to go into production in early 1946, with a more powerful Heinkel-Hirth 011A turbojet providing 12.75 kN (1,300 kgp / 2,870 lbf) thrust, along with a fuselage stretch to provide more fuel and endurance and increased wingspan, with proper dihedral and discarding the turned-down wingtip extensions. The He-162B-1 was to be armed with twin MK-108 30 millimeter cannon. In reality, only nine Heinkel-Hirth 011A turbojets were ever completed and the He-162B-1 never happened.

The He-162B airframe was also used as the basis for possible designs powered by pulsejet engines, one concept using a single Argus As-044 engine with 4.9 kN (500 kgp / 1,100 lbf) thrust and the other using twin Argus As-014 engines with 3.26 kN (332 kgp / 734 lbf) thrust each. Although pulsejets, unlike ramjets, can in principle produce static thrust, the Argus pulsejets didn't produce enough power at low speeds for takeoff, and so various launch schemes were considered, ranging from towplanes to catapults to the most intelligent solution, a rocket-assisted takeoff booster unit under the rear fuselage.

""" However, neither the Luftwaffe nor Heinkel engineers were at all enthusiastic about the pulsejet powered He-162 variants. Pulsejets had poor high-altitude performance, bad fuel economy, and high levels of vibration. Pulsejets operate with a pulsed combustion scheme that gave them a loud, low, rapid "putt-putt" sound, and a ride in an aircraft with such engines was likely to be rough. Messerschmitt had experimented earlier in the war with a fighter designated the "Me-328" powered by twin pulsejets, and engine vibration eventually led to the loss of the aircraft. The pulsejet-powered He-162 project was driven from the top, with the aircraft perceived as almost completely expendable. Although three airframes were set aside for testing, they were never fitted with the Argus engines.

Other He-162 variants under consideration included the "He-162C", with the B-series fuselage, Heinkel-Hirth 011A engine, swept wing, and "vee" or "butterfly" tail assembly; and the "He-162D", with a similar configuration but a forward-swept wing. They were to me armed with twin MK-108 30 millimeter cannon, and a scheme was considered in which the cannon could be pivoted upward from the horizontal, allowing the fighter to fire at a bomber while flying under it.

The He-162C and He-162D got no farther than a half-completed prototype that could be fitted with interchangeable forward-swept or back-swept wings, discovered by the Allies when they occupied the plant at Schwechat.

In fact, the only advanced variant of the He-162 that was actually flown was the "He-162E", which was an He-162A fitted with the BMW-003R mixed power plant, which was a BMW-003A with an integrated BMW-718 liquid-fuel rocket engine for boost power. At least one prototype was built and flight-tested for a short time.

* The advanced He-162 variants have proven to be of interest to modelers, particularly the imaginative LUFTWAFFE 1946 interest groups, which project the aircraft that the Third Reich might have had available had the war lasted longer. Model kits of many of these mystery aircraft are available from specialty model companies. """

wow ,c'est trop beau http://forums.ubi.com/infopop/emoticons/icon_eek.gif http://forums.ubi.com/infopop/emoticons/icon_eek.gif
des aile avec un angle, il va faire un malheure celui-la j'imagine. plus stable a grande vitesse grace à ses aile et pouvant surement allez plus vite aussi.

Ouin...les ailes inversées aussi, ça l'air fou! http://forums.ubi.com/infopop/emoticons/icon_eek.gif
