WSK PZL-Rzeszow of Poland has introduced an up-rated version of its popular GTD-350 turbo shaft engine, which powers the Mil Mi-2 helicopter. The GTD-350W offers improved compressor efficiency, resulting in an increase in take-off power of 18kW, to 315kW. The improvements are also available as a retrofit for existing engines. To date, some 50 GTD-350Ws are in service in five countries.
The company also manufactures the PZL-10W turbo shaft, which powers the PZL-Sokol twin-engined helicopter.
