Two major developments in the Chinese aerospace industry were revealed at the recent Singapore airshow. United Aircraft Group announced a tilt rotor UAV in the six-ton class, capable of carrying cargo and passengers for both civilian and military applications, and the COMAC C919 airliner received another order for 40 aircraft for Tibet Airlines, in a special high-altitude configuration. The C919 is crucial for the success of the Chinese civilian aircraft industry, competing in the most important single aisle market segment in commercial aviation, currently dominated by the Airbus A320 series and the Boeing 737.  * * * Want to watch this podcast as a video?
