AI Technical Summary
It is difficult for the existing technology to achieve effective ejection and takeoff of various models of aircraft (1 ton-150 tons) all-weather, and the singularity of the power supply system poses a risk of power outage accidents.
A multi-function electromagnetic catapult was designed, using the main channel and two subsidy channels. The main channel and subsidy channels each have independent power supply systems to ensure that the subsidy channels can still take off effectively when there is a problem with the main channel. At the same time, through the design of the fixing plate and screws, the three lanes are fixed in one, ensuring that the thrust weight reaches 1 ton-150 tons.
It has achieved effective ejection and takeoff of various models of aircraft all-weather, ensuring the safe takeoff of the aircraft, and reducing the risk of power outage accidents through an independent power supply system.

Abstract
Description
[0001] This patent invention is a multi-functional electromagnetic catapult. The multi-functional electromagnetic catapult can perform catapult launches all day long for various types of aircraft, such as the J-10, J-11, J-15, J-16, J-17, J-20, J-31, J-35, early warning aircraft, medium bombers, medium aerial refueling aircraft, and unmanned aircraft. It can handle aircraft with weights ranging from 1 ton to 150 tons and has variable-frequency thrust-to-weight ratios. It has a main track and auxiliary tracks. If there is a problem with the main track, the two auxiliary tracks can still be used for takeoff and the aircraft can fly into the sky.
[0002] In addition, for the multi-functional electromagnetic catapult, each track must have an independent power supply system to ensure that the power supply does not short-circuit. There is one circuit for the main track and two circuits for the two auxiliary tracks. The catapult track is 80 meters long. For a two-track multi-functional electromagnetic catapult, the three tracks are fixed together to be able to handle the takeoff of aircraft with weights from 1 ton to 150 tons.
[0003] (1) A is the main track, and B and C are the auxiliary tracks, which play an insurance role and can still perform catapult launches.
[0004] (2) There are six fixing plate screws to fix the one-catapult-three-track integrated multi-functional electromagnetic catapult. The three tracks are fixed together.
[0005] (3) The catapult launch assisting hook helps the front guide wheels of the aircraft for takeoff.
[0006] (4) The catapult launch fixing plate is for the one-catapult-three-track integrated multi-functional electromagnetic catapult. It can perform catapults with a thrust of 1 ton to 150 tons.
[0007] (5) The front deck of the aircraft carrier has a catapult track that is 80 meters long.
[0008] (6) Each of the one-catapult-three-track system must have an independent power supply system to prevent power outage accidents.

Claims
1. The patented invention is a multi-functional electromagnetic catapult, which is an innovation based on the original. I. It can catapult various types of fighter jets, such as: J-10, J-11, J-15, J-16, J-17, J-20, J-31, J-35. Early warning aircraft, medium bombers, medium air refueling aircraft and unmanned aerial vehicles. II. I have developed a super electromagnetic catapult, which can be directly repaired. Whichever part is broken, it can be directly repaired. III. The super electromagnetic catapult has a three-in-one structure. Track A is the main catapult track. Tracks B and C are auxiliary tracks. The ABC integrated electromagnetic catapult device. Track B is to assist Track A. If Track A breaks down or has problems, Tracks B and C can still catapult the aircraft for takeoff. Track C is to assist Tracks A and B. If Tracks A and B break down or have problems, Track C can still catapult the aircraft for takeoff. If two of the ABC tracks are broken, the aircraft can still take off, and after the catapulting, it can be repaired and still catapult for takeoff. (1) A is the main track. B and C are auxiliary tracks, which play an insurance role and can still catapult the aircraft for takeoff. (2) There are six fixing plate screws to fix the one-catapult three-in-one multi-functional electromagnetic catapult. The three tracks are fixed together. (3) The catapult takeoff assisting groove helps the front guide wheels of the aircraft for takeoff. (4) The catapult takeoff fixing plate, the one-catapult three-in-one multi-functional electromagnetic catapult. It can catapult with a thrust of one ton - 150 tons. (5) The front deck of the aircraft carrier. The catapult track is 80 meters long. (6) Each of the one-catapult three tracks must have an independent power supply system to prevent power failure accidents. Note: This patented multi-functional one-catapult three-in-one multi-functional electromagnetic catapult has an electromagnetic catapult length of 80 meters, a catapult weight of one ton - 150 tons, and can send the aircraft into the blue sky.
