Development of rocket planes in the USSR

 

In 1940 of pilot VP Fedorov flew to the missile-carrying SC-9 (Sergei Korolev-9) design of our compatriot, one of the founders of the Soviet space program. The aircraft rocket engine was installed RDA-1-150, created by LS Dushkin based engine ORM-65 design Glushko.

1941 In August, it was decided to build the Soviet fighter liquid rocket engine (LRE). This aircraft was designed to perform a single attack on an aerial target in the same flight. Short time of the engine should be, according to the designers, enough to dial a short time the necessary height.

After the attack aircraft, using aerodynamic quality, I had to land at the airfield. It was a bold project. Implementation of the plan could not have a positive outcome. Knowledge in the field of flying objects flying at high speed was not enough. It has not been studied questions of stability and controllability of the aircraft flying at speeds of up to 800 km / h (design speed fighter). Serious problems were liquid jet. Even a bench test it does not always end well.

The plane constructed AI Bereznyak and AM Isaev led VF Bolkhovitinov. Hence the name of the aircraft - BI-1. The first flight took place on May 15 1942, the time of the engine was a 66. The flight lasted 3 9 minutes with. Flight height - 840 m, flight speed - 400 km / h, a vertical rate of climb - 23 m / s. Test flight made captain GY Bahchi- Vangi, he alone continued to experience this plane.

In subsequent flights it had reached the height of 4000 m, flight duration - more than 6 min.

27 1943 March was held the seventh test flight GY Bah- chivandzhi Bi-1. In accordance with the task needed to reach the speed of 750-800 km / h. In this flight brave pilots died. It was the last flight of the domestic jet Bi-1.

After World War II the advanced countries of the world have revised their policies in the field of combat aircraft. In the middle of 1940-ies. in the United States were built experimental rocket plane Bell X-1 and Bell X-2. This took into account the results of the development and operational use of the German wartime rocket plane Me-163.

 

Bell X-1

 

The first flight on the aircraft Bell X-1 was in December 1946, with the duration of the flight a little over 4 rocket-minute plan could reach speeds of 2560 km / h and climb to an altitude of more than

21000 m. For the first time in November 14 miret1947 city by plane Bell X-1 reached supersonic speed - 1 224,5 km / h at an altitude of 10800 m. The flight was made an American pilot, Captain Robert Yeager. The significance of such flights can not be overestimated: a response was received to the question on the behavior of the aircraft on sound and supersonic speeds.

In 1953 the firm of "North America" ​​was designed and built an unmanned experimental aircraft Laboratory X-10.

Powerplant: two engine Ju-40 (another designation - J-33). The jet engine with centrifugal compressor passed bench tests in Lynn, flight - in California. For the first time a new engine installed on the aircraft F-80. Flight tests of the aircraft gave a great and useful scientific material used in the development of new aircraft. The aircraft was later applied to the layout of X-10: the shape of the wing, empennage.

16 September 1956, the American pilot Everest plane Bell X-2 reached speeds in 3 times the sound.

Outstanding speed record for rocket planes were established by American pilots in 1960-ies. Bella on the plane X-15.

Rocket engines, particularly liquids, have been used as an additional power plant, operated at the start of the aircraft. This facilitated the implementation of take-off. Engines could be built-in or suspended.
