the SPECIAL ASSAULT AIRCRAFT of JAPAN. By early 1945, the Japanese military-political leadership was aware that sooner or later we should expect the allied invasion to the territory of Japan proper. This understanding has penetrated all layers of Japanese society. The bombing of cities and industrial enterprises were conducted daily, and the armed forces of the Empire fought desperately, pressed on all fronts.
The first and most important work on the rotating propeller to generate lift forces were made in the period between the world wars. Thus, it was found that the spinning rotor can generate lift force, maintaining its rotation from the incoming flow. Any drive to the rotor in this case was not needed. This mode is called “autorotation”. Its use allowed the Spanish designer Juan de La Cierva to invent the autogyro.
By the middle of 1950-ies the main front-line reconnaissance aircraft was considered to be Il-28R. But the car, excellent in all respects, by the time against the backdrop of recent supersonic fighters became morally obsolete. Created at the same time, the Yak-25P, although outnumbered, “Il”, but the requirements of the military on the prospective scout is also not satisfied. In this situation, OKB A. S. Yakovlev proposed to develop a supersonic fighter-scout with engines AM-9F (RD-9F). The government and the military supported the proposal and in March 1956 was signed the corresponding decree.
Aerospatiale SNI, a leading aerospace firm in France, with four offices, including a helicopter. Company Aerospatiale SNI takes a leading place in Western Europe for the production of helicopters.
In 1943 the situation of the Reich was not yet threatening: the front was far from his borders, and the Wehrmacht, with varying success, was fighting on foreign soil. However those soldiers who were not completely affected by Nazi propaganda, knew that in order to save Germany from defeat, you must not only defeat the Soviet Union, but also to keep the allies from being thrown across the channel and thus prevent the danger of opening a second front. These officers understood that when the level of development of science and technology only the projectile, a person giving a guarantee of reliable defeats the purpose. There is therefore nothing surprising in the fact that the group of senior officers of the Luftwaffe, the idea was to create a unit manned flying bombs, capable of finding and hitting any important target, especially the heavy ships of the allies preparing for the invasion.
Hypersonic rocket plane North American X-15. The construction of the spacecraft reusable type Shuttle “Buran” opened a new Chapter in manned space exploration. The design of this type of device has requested giant engineering research related to the problems that arise when flying at high altitudes and speeds.
The plane was developed at the request of the Polish air force jet training plane. It was the first jet car built in Poland. Work began in 1957, the First prototype with a British engine, the Armstrong first flew on 5 February 1960, the Following two prototypes had the engine “Viper”.
Designing a training jet aircraft Yak-30 began in the Yakovlev design Bureau in 1957, In 1960 it was built two prototypes, which were tested from may 1960 to March 1961, there were performed 82 flight a total duration of 43 hours 36 mins No difficulties in the operation of the airplane and engine did not arise.
The Grumman F6F HELLCAT. Analysis of the results of air combat in South-East Asia with the participation of the new Japanese high-speed fighters allowed American experts to draw a conclusion about necessity of creation in the US carrier-based fighters with higher performance. Orders to create prototypes were issued to multiple firms.
Strategic bomber b-52 STRATOFORTRESS. Contest project of a new reagent tion of the strategic bomber to replace the CONVAIR piston-IN-36 were announced, the U.S. air force in 1946. Despite the fact that some high-ranking air force officers did not believe in the possibility of the construction of a heavy jet with a range of over 13,000 km, company Boeing, Convair and Douglas enthusiastically set to work.
