The Sukhoi Su-5 was a mixed-power interceptor. It had a Klimov VK-107A piston engine in the nose and a VRDK motorjet compressor. an axial compressor driven by a long shaft from the VK-107A. The motorjet was a stop-gap solution that was quickly superseded once genuine jets appeared. https://www.destinationsjourney.com/historical-military-photographs/sukhoi-su-5/ #SukhoiSu5 #aeroplane #Aircraft #airplane #aviation #fighter
