I thought this one might be easy, as I used it before as a "mystery plane" on my old website. Aircraft #8 is the Berenznyak-Isayev (also known as Bolkhovitinov) BI-1. The image is from page 37 of "Under the Red Star; Luftwaffe aircraft in the Soviet Airforce" by Carl-Fredrik Geust, 1993.
The BI-1 was the first rocket-powered fighter built in the Soviet Union. Most of its structure was of wood covered with fabric, while the rocket engine was a Dushkin D-1A, which in its later versions provided 1,100 kg of thrust. First powered flights were in early 1943 and later that year a top speed of nearly 560 mph was recorded. On 27 March, 1943, on the seventh flight, the BI-1 crashed, killing noted test pilot G. Ya. Bakhchivandzhi. A replica of the aircraft is on display at the museum in Monino, Russia. The link below has more information on the design.
