An autogyro, also known as a gyroplane or gyrocopter, is a type of rotorcraft that uses an unpowered rotor in free autorotation to develop lift. Forward thrust is provided independently, by an engine-driven propeller. While similar to a helicopter rotor in appearance, the autogyro's rotor must have air flowing across the rotor disc to generate rotation, and the air flows upwards through the rotor disc rather than down.

Shaanxi Baoji Special Vehicles Manufacturing Co., Ltd  is a large manufacturer of light armored vehicles that also produces Hunting Eagle light gyroplanes for the needs of the PLA army aviation and other power structures of the People's Republic of China.
