Problems solved by technology
[0002] The carrier-based aircraft catapults used on aircraft carriers in all countries in the world are mainly steam-type catapults. Although the technology of steam catapults is mature, they are complex in structure, large in size, high in cost, and poor in technical performance. They belong to backward military technology in the past. The electromagnetic catapult system uses electromagnetic power to catapult carrier-based aircraft, and has the advantages of simple structure,
[0003] The advantages of small size, low cost, and high technical performance belong to the advanced military technology in development. The commander of the US aircraft carrier first used the electromagnetic catapult system, but its technology is not mature, there are many faults, and it has not been installed.

[0016] The following is a further description with reference to the drawings.
[0017] in Figure 1-Figure 8
[0018] When the carrier-based aircraft is ready to take off, press the take-off button to start the low-speed brushless permanent magnet outer rotor motor to rotate clockwise, the intelligent controller controls the electromagnetic clutch to pull in and drive the linear outer mover, and the low-speed brushless permanent magnet outer rotor motor works at The low-speed state with high efficiency and high power drives the linear outer mover to accelerate forward from the low-speed stage to the middle-speed stage. When the permanent magnet particles are aligned with the middle Hall sensor, the front ends of the left permanent magnet strip and the right permanent magnet strip arrive Linear inner stator, middle Hall sensor control low-speed brushless permanent magnet outer rotor motor to automatically shut down, control high-speed brushless permanent magnet linear motor to driv...

Abstract
The invention discloses a relay acceleration aircraft carrier shipboard aircraft electromagnetic catapult. The catapult consists of a high-speed brushless permanent magnet linear motor, a low-speed brushless permanent magnet outer rotor motor, an electromagnetic brake, an electromagnetic clutch and a catapult connector, a linear outer rotor is positioned between a left gripper guide rail and a right gripper guide rail and translates back and forth; the low-speed brushless permanent magnet outer rotor motor and the linear inner stator are both located in the middle of the electromagnetic catapult. Automatic gear shifting and relay acceleration are carried out between the low-speed brushless permanent magnet outer rotor motor and the high-speed brushless permanent magnet linear motor; the maximum power and the maximum efficiency of the low-speed motor and the high-speed motor are brought into full play to drive the linear outer rotor, the high-low voltage conversion button is pressed according to the size of a shipboard aircraft, different take-off voltages are selected, the electromagnetic catapult with controllable thrust is achieved, and the V-shaped guardrail of the catapult connector has the functions of automatic connection, separation and collection.
Description
Technical field [0001] The invention relates to an electromagnetic catapult for an aircraft carrier-based aircraft, specifically an electromagnetic catapult for a relay acceleration aircraft carrier-based aircraft. Background technique [0002] The carrier-based catapults used on aircraft carriers in various countries around the world are mainly steam-type catapults. Although the technology is mature, steam catapults have complex structure, large size, high cost, and poor technical performance. They belong to the backward military technology in the past. The electromagnetic catapult system uses electromagnetic power to eject carrier-based aircraft. It has a simple structure, [0003] The advantages of small size, low cost, and high technical performance belong to the advanced military technology in development. The US aircraft carrier Shangshuai first used the electromagnetic catapult system, but its technology was immature and there were many faults, and it could not be installed....
