Abstract

The invention discloses a carrier-based aircraft catapult device for an aircraft carrier, and belongs to the technical field of electromagnetic ejection. The catapulting device comprises a rack unit, a catapulting vehicle, a main motor and a gap bridge motor. The upper portion of the rack unit is provided with a track, the lower portion of the rack unit is fixedly connected with a main motor and a gap bridge motor, and the main motor and the gap bridge motor with outer rotors provided with spur gears are alternately and horizontally arranged in the longitudinal direction of the rack unit and meshed with the gears to form a transmission chain connected in series front and back. A plurality of main motors, the gap bridge motors and a rack unit form an independent machine base, and a plurality of machine bases are connected front and back to form acatapulting working area. A rack on the lower portion of the catapult car is meshed with an outer gear of the main motor, and when the motor is started to accelerate, the catapult car slides along the track to drive the aircraft to take off in an accelerated mode. According to the device, the rack multi-point meshing technology and power series connection superposition are adopted to meet the working requirements of high power, large thrust and high acceleration of an aircraft carrier shipboard aircraft catapult, and the device has the advantages of being high in adaptive capacity and transmission efficiency, reliable in work, low in cost and the like.

Description

Technical field: [0001] The invention belongs to the technical field of aircraft carrier electromagnetic ejection equipment, and in particular relates to an aircraft carrier aircraft ejection device. Background technique: [0002] The carrier-based aircraft ejection device is the key equipment for assisting the take-off of large aircraft on the aircraft carrier. With the help of the carrier-based aircraft ejection device, the space occupied by the aircraft take-off runway and the aircraft carrier deck can be greatly reduced, and the reliability and efficiency of aircraft take-off can be improved. It is of great significance to improve the combat effectiveness of the aircraft carrier. The existing steam catapult device is a successful carrier-based aircraft catapult device, which has the advantages of simple structure, large thrust, small moving mass and high take-off acceleration. The short service life of the sealing strip and the high maintenance cost are disadvantages. ...
