2000KW & 5000KW turboshaft engines powerful enough for the largest of helicopters...
??????5000?????????????_????_???
At least three type of turboshaft engines have been successfully tested for WZ-10,
all of them foreign built. Russian Klimov VK-2500 turboshaft engine that powers Mil Mi-17s sold to China is among the ones used, and so are the Pratt & Whitney Canada PT6C-67C that powers civilian helicopters of western origin in Chinese service. Ukrainian Motor-Sich TV3-117 that powers Mil Mi-28 has also successfully tested, and Ukrainians are helping Chinese to develop its own indigenous turboshaft engine
The future, long-term engines for the WZ-10 will be the domestic WZ-9 (WZ = Wo Zhou, 涡轴, designed by the 602nd Research Institute, with Ukrainian and Russian assistance. The previously erroneous claim of WZ-9 being a Chinese version of MTR390 proved to be false, because according to the publicized official Chinese governmental technical documents, VK-2500, TV3-117 and PT6 are all classified as third generation turboshaft engines, a category Wozhou-9 belongs to, while MTR390 is classified as a fourth generation turboshaft engine.
Wozhou-9 is the least powerful engine out of the five tested for WZ-10, but enjoys the advantage of lowest operational cost because there is no foreign built component. Furthermore, since it is 100% built in China, there are no political issues that would affect the purchase of vital parts. Wozhou (WZ)-9 is scheduled to enter full operational service by the end of 2009.
The transmission system was developed with the help of Agusta Westland.
Specifications for Wo Zhou - 9 (涡轴-9) turboshaft engine which installed in WZ10 for mass production :
Power: 1000 kW
Fuel consumption: 0.311 kg/(kW·h)
Pressure ratio: > 8
Inlet temperature: 1355 degrees Celsius
Power-to-weight ratio: 5.4
Another new engine is under development,
it is developed by China and Turbomeca. It is called the WZ16 (涡轴16) turboshaft engine. This development appeared in Tianjin Heli Expo in 2011. Its max out put power is 1500 kw, and will be installed in the WZ10 and Z-15 /EC175. After the installation of the new engines power would increase by 500 kw for WZ10. With WZ-9 turboshafts, WZ10 can carry 16 HJ-10 missiles with max take off weight, but the payload is very heavy for the WZ10 and engines and potentially risky for flying, so 8 missiles with other weapons serve as the max useful payload. After new WZ16 engines are installed in the WZ10, it can carry 16 of them like AH-64.
