BI – 1
The first Soviet rocket plane.The flight to the BI-1 was difficult and not only from habit. It was possible to sit on it only after the development of fuel, it was unpleasant to have close proximity to nitric acid under high pressure, sometimes breaking out through the wiring joints, and even through the walls of pipes and tanks. These damage had to be repaired all the time, which greatly delayed flights that continued throughout the winter of 1942-1943. During their death, Grigory Yakovlevich Bahchivandzhi died on March 27, 1943, when the plane at a speed of over 800 km / h from a horizontal flight went into a dive from which it could not get out. The reason became clear only later. The wine was a straight (non-swept) wing, which has the effect of pulling into a dive at speeds of 900 km / h or more..
