The Mikoyan-Gurewitsch Je-2A ( Russian Микоян-Гуревич Е-2А ) was an aircraft study by the Mikoyan-Gurewitsch design office .
development
As part of the development program for a Mach 2 fighter, the prototype Je-1 received the more powerful AM-9B engine and thus became the Je-2, with only minor modifications to the airframe . The structural design of the Je-2 was based on the earlier SM-12 prototype. The Je-2 was completed at the end of 1954 and flown in on February 14, 1955. The first flights did not show any performance differences between the arrow (2 each) and delta wing prototypes (4 each) that were tested in parallel, so a further prototype of the corresponding configuration was ordered, the 2A and 5 each. Both should get the much more powerful AM-11 engine. The Je-2A flew for the first time on March 22, 1956. In addition to the new engine, it received a boundary layer fence on each wing. Compared to the Je-2, the performance had increased significantly, and so a small pilot series of five machines was built as the Isdelije 63 for further extensive tests. In 1956, the Je-2A was also shown publicly at an air parade. The trials ultimately showed the superiority of the delta wing design of the Je-5, which then formed the initial model of the successful MiG-21 .
