TECHNICAL FIELD

[0001] The utility model relates to the technical field of military equipment, in particular to an electromagnetic ejection power-assisted system. BACKGROUND

[0002] Ejection technology has application requirements in military, aerospace, civil and industrial fields. The most representative is electromagnetic ejection technology, which can realize smooth propulsion, automation and intelligence because the electromagnetic ejection propulsion force can be accurately controlled. China's most advanced Fujian aircraft carrier and America's most advanced Ford aircraft carrier have begun to use it.

[0003] The electromagnetic ejection technology used by aircraft carriers belongs to military industry, and its technical details and performance are unknown, which is inconvenient to discuss. According to the public reports, for example, a kind of aircraft carrier-based aircraft electromagnetic ejection device is disclosed in the utility model patent with application number 201710819541.0, the main structure of which includes a platform, two connecting plates are fixed symmetrically on the lower end of the platform, the two connecting plates pass through the openings of the left and right linear motor stators, the lower end of the connecting plate is fixed with the upper end of the linear motor mover, the inner wall of the linear motor mover is fixed with the outer wall of the central shaft, the base is fixed with the linear motor stator, a pair of symmetrically arranged guide electromagnets are fixed on both sides of the opening of the linear motor stator, the lower part of the linear motor stator has a pair of symmetrically arranged suspension electromagnets A with the center line, and the lower part of the linear motor mover has a pair of symmetrically arranged suspension electromagnets B with the center line; in use, the carrier-based aircraft is parked on the platform and clamped, the power supply of the suspension electromagnets A and B is started, the suspension electromagnets A lift the linear motor mover and the platform, and then a pair of guide electromagnets are started at the same time, so that the connecting plate is always in the middle position of the pair of guide electromagnets, and then the forward power supply of the two linear motor movers is started, the linear motor mover moves forward along the linear motor stator, and drives the platform to move forward, so that the carrier-based aircraft takes off.

[0004] However, the core of electromagnetic ejection is linear motor, and the starting current of linear motor load increases by nearly ten times. On the aircraft carrier, the peak demand of heavy carrier-based aircraft ejection power is close to one hundred thousand kilowatts, and the peak power consumption of electric energy is estimated to be close to five hundred thousand kilowatts. It is a technical problem to supply such high electric energy on the aircraft carrier. Moreover, after ejection, the linear motor becomes a heater of several hundred thousand kilowatts in an instant, which not only easily causes the ejection device to overheat and burn out, but also needs forced cooling, increasing the complexity of the system. UTILITY MODEL CONTENTS

[0005] To solve the above technical problems, the utility model provides an electromagnetic ejection power-assisted system which assists in traction of carrier-based aircraft through steam motor, reduces the electric quantity required by electromagnetic ejection, and has the advantages of high thermal efficiency and small volume of motor ejection, reduces the dependence on electric energy, and improves the ejection capacity.
