An engine intended for helicopters. It is a version of the Soviet Ivchenko AI-26V engine, licence-built in Poland by PZL Rzeszów. In mid-50s Poland purchased the license for the Mi-1 helicopter and its engine.
The engine is fitted with a single-stage supercharger, a bevel gear transmission assembly, driving the main and tail rotor, a clutch for smooth coupling and decoupling the engine with the rotors and a cooling fan. Compressed air is used for the engine startup. It was a powerplant of the SM-1 (license-built Mi-1) and SM-2 helicopters.
