A new Chinese unmanned hypersonic aircraft can rival the aerodynamic performance of advanced US military fighters, scientists from Beijing say. The new hypersonic drone boasts a lift-to-drag ratio of 8.4 in subsonic flight, already at par with the F-22 Raptor. The lift-to-drag ratio is a crucial parameter for measuring aerodynamic efficiency. A higher value indicates greater resistance of the aircraft to the pull of gravity and enables it to fly a greater distance. The F-22 is the only stealth fighter in the US military capable of supercruise, or sustained flight at supersonic speeds. Watch thee video to know more about the drone
