...the K800 vertical take-off unmanned aerial vehicle (VTUAV), is focused on developing future high-speed helicopters. The K800 utilises an advancing rotor concept likely to employ a co-axial main rotor with an additional propeller for horizontal thrust. It has a weight of 800 kg and a designed speed of 450 km/h. The programme is similar to that represented by two models of co-axial rotor VTUAVs displayed at last November's Zhuhai Airshow 2012 as part of the so-called 'Avant Courier' concept - one with an aft-mounted horizontal-thrust propeller like the US Sikorsky X2, and a second with two side-mounted propellers similar to the Eurocopter X3.
