A WZ 5 turboshaft engine has been modified with a rebuilt high temperature turbine as a ground power plant.The engine can make full use of its turbine inlet temperature through varying areas of both gas generator turbine and power turbine nozzles and reduce the rotor speed

thus a sufficient surge margin is provided and the output shaft power is enhanced.Therefore

the engine meets the requirements for long time operation when it serves as a power plant in varied ground industrial complex.The practice of its usage has shown that the modified WZ-5 is of considerable economic and social benefits.
