Mikoyan-Gurevich I-270
- Glide: December 1946
- With drive: March 1947
The Mikoyan -Gurevich I-270 (Russian Микоян - Гуревич И -270, NATO reporting name Type 11 ) was a Soviet rocket plane. It was created shortly after the end of the Second World War and was inspired by the German Junkers Ju 248, from 1945, a complete copy had fallen into the hands of the Red Army in the conquest of the Junkers works, but is a self-construction dar. So decreed the I -270 in contrast to the swept wing of the Ju 248 via a conventional trapezoidal wing and a horizontal stabilizer.
History
Development work began after the development of the engine 1945 OKB Mikoyan- Gurevich who entered new technological territory with this type. It produced two prototypes under the project name " Sch " (Russian Ж, the abbreviation for liquid rocket engine ).
Power was a building designed by Leonid Dushkin and Valentin Glushko according to German documents two-chamber rocket engine with a burning time of 4.24 min at maximum power, with one chamber to those required for take-off and climb performance maximum thrust of 14 kN produced and the other the march thrust of 4 kN. The total burn time with minimum power was 9.3 min.
The configured in all-metal construction I-270 received a pressurized cabin and a mounted on the vertical tail gepfeiltes tailplane. Since the trapezoidal wing of the middle Deckers was kept very thin with a laminar profile, the chassis pulled into the spindle-shaped hull.
Flight testing began in 1946 under the test pilots W. N. Juganow. Like their German predecessors provided the I-270, although for that time remarkable flight performances, but also suffered from the typical shortcoming of too short range. The further development of this project was therefore discontinued in favor of the parallel is located in the test phase MiG -9 jet propulsion. Both prototypes were destroyed during the testing in crashes.
