WZ10 turboshaft

The WZ10 turboshaft is a domestic development study for a high-power turbine shaft, with a power of 1800 kilowatts, that would enter production around the year 2015 for the new "20 Ton" helicopters. Russian arms maker Oboronprom and China's AVICopter signed a memorandum to jointly develop a civilian heavy helicopter based on the Mi-46. Oboronprom referred to the planned Mi-46 as having a takeoff weight of 30 tons, but the phrase "20 ton" has long been used in China to designate the future helicopter meeting requirements in this weight class.
