history

The BI-8 was a project by Alexander Bereznjak and Alexei Isajew in the late 1940s and early 1950s. The previous BI project had been discontinued due to various problems, in particular a downward slope at high speeds. After years of tinkering, the two designers managed to fix the problem.

They wanted to fly extremely fast with the BI-8. The plan was to use the improved D-1A-2100 rocket engine and six RD-20 rocket engines at various points on the aircraft on the left and right. The aircraft was intended as an interceptor against bombers . Similar to the concept of the Messerschmitt Me 163, it was supposed to rise at high speed to an altitude of 10,000 meters and from there attack the bombers while gliding . The firepower of eight SchWAK cannons was exceptionally strong.

In 1951 the aircraft was largely completed and flown without engines. The pilot was Sergei Gorbacheyev. A month later the project was canceled due to lack of money.
