Development
The Z-11 project started in 1989 and the first flight was made in Dec 1994. In Oct 2000, test flights of Z-11 were completed. The chief designer of Z-11 is Mr. Wu Ximing (吴希明), who is also the chief designer of three other Chinese helicopters, including the WZ-10. Under Mr. Wu, the Z-11 became the first Chinese helicopter to be completely designed using CAD/CAM techniques.[2]
The Z-11WB, the attack and reconnaissance variant, features pintle mount weapons and two weapon pylons on each side of the aircraft.[3] The engine is replaced by Turbomeca Arriel 2B1A turboshaft engine developing 632 kW (848 shp) of power.[4]
