The invention discloses an electromagnetic catapult of an aircraft carrier shipboard aircraft. The electromagnetic catapult is composed of an aircraft carrier, a shipboard aircraft, an electromagneticcatapult, a rail pulley vehicle, a cone winch, a return motor, an electromagnetic brake, an electromagnetic clutch, a storage battery pack, an intelligent controller and an operation table. The conewinch pulls the rail pulley vehicle to push the shipboard aircraft to realize electromagnetic catapult-assisted take-off; the perimeter of the lower end of the cone winch is small; the steel wire ropeis large in tension, the pulling speed is low, and the circumference of the upper end of the cone winch is long; the steel wire rope is small in tension, the pulling speed is high, the rotating speedof the high-speed outer rotor permanent magnet brushless motor is fixed, the linear speed of the steel wire rope is the acceleration in a stepless speed change state, the high-speed outer rotor permanent magnet brushless motor always works in a high-rotating-speed state with high efficiency and high power, the number and the voltage of the storage batteries are adjusted, the electric quantity andthe power required by catapult-assisted take-off of the shipboard aircraft are met, different take-off voltages are selected by pressing a high-low voltage conversion button according to the size ofthe shipboard aircraft, and the beneficial effect of controllable electromagnetic catapult-assisted thrust is achieved.
