Kawasaki Heavy Industries successfully completed flight tests of the “K-RACER” unmanned helicopter at the Taikicho Aviation Park in Hokkaido.
This machine is a special type of UAV – rotorcraft, which has a main rotor (4 m in diameter), wings and pulling rotor on the left and right side instead of the tail rotor.
The propellers on the wings neutralize the torque caused by the rotation of the main rotor and create direct thrust. In addition, in direct flight, the wings increase lift by reducing the load on the main rotor, providing high-speed flight that cannot be achieved with conventional helicopters.
The heart of the UAV is the supercharged engine of the “Ninja H2R” motorcycle thanks to the technical cooperation between Motorcycle & Engine Company and the headquarters of technological development.
