A permanent magnetic levitation ejection aid system

Abstract

The invention discloses a permanent magnetic suspension type ejecting and flying assisting system. The system is characterized in that a fixed permanent magnetic railway (1) and a movable permanent magnetic railway (2) are oppositely mounted in parallel; a permanent magnet mounted on the fixed permanent magnetic railway (1) and the permanent magnet mounted on the movable permanent magnetic railway (2) are in opposite N-S pole direction, so that the movable permanent magnet railway (2) can be suspended above the fixed permanent magnetic railway (1); a copper-steel composite plate (8) is mounted at the bottom part of an aircraft; a power panel (5) is mounted above the movable permanent magnetic railway (2); a motor drives the power panel (5) to rotate to cut the permanent magnet on the fixed permanent magnetic railway (1) to produce a magnetic line of force which leads to electromagnetism to push the movable permanent magnetic railway (2) to drive the aircraft (6) to accelerate to move forwards, and then the aircraft (6) is separated from the movable permanent magnetic railway (2) to independently fly. The system is compact in structure, stable to suspend, small in energy consumption in acceleration, and obvious in flying assisting effect.

Description

technical field [0001] The invention relates to the technical field of permanent magnetic levitation, in particular to a permanent magnetic levitation ejection aid system. Background technique [0002] Carrier-based aircraft need to use catapults to successfully take off on the aircraft carrier. At present, there are mainly two types of aircraft carrier catapults: steam catapults and electromagnetic catapults. The technology of the steam catapult is relatively mature, but it has the disadvantages of bulky size, high energy consumption, labor-intensive maintenance, and high operating cost. The electromagnetic catapult uses electromagnetic force to accelerate the aircraft. Its working principle is similar to that of an electromagnetic linear motor. However, in order to achieve full acceleration, the electromagnetic catapult requires a long track, which has disadvantages such as high failure rate, difficult maintenance, high energy consumption and low work rate. .

The technology of the steam catapult is relatively mature, but it has the disadvantages of bulky size, high energy consumption, labor-intensive maintenance and high operating cost.

The electromagnetic catapult uses electromagnetic force to accelerate the aircraft. Its working principle is similar to that of an electromagnetic linear motor. However, in order to achieve full acceleration, the electromagnetic catapult requires a long track, which has disadvantages such as high failure rate, difficult maintenance, high energy consumption and low work rate.
