technical field

The present invention relates to the field of permanent magnet technology, in particular to a permanent magnet magnetic levitation assisting system.

Background technique

The carrier-based aircraft needs to use the arresting cable to successfully land on the aircraft carrier. The aircraft carrier arresting cable is an interception device system applied to the aircraft carrier. It is located at the rear of the flight deck of the aircraft carrier. In a few seconds, the fighter plane is rapidly decelerated, the speed per hour is reduced to zero, and the sliding distance of the fighter plane does not exceed 100 meters. The arresting cable arresting device involves many high-tech technologies such as machinery, electricity, and hydraulic pressure, and is a huge and complicated project. The arresting cable needs to directly withstand the impact force and blocking force of the tail hook of the carrier-based aircraft, and must have high fatigue resistance and continuous working performance. The requirements for hardness and toughness put forward strict requirements on the material process of the arresting cable. The principle and technology of carrier-based aircraft interception is very difficult. Among them is the arresting cable support system with a unique structure, which is a device that raises the arresting cable to a specified height, so that it can be lifted to hook the tail hook of the carrier-based aircraft after the run, and it cannot be too high to catch the "dual hook" of the Warhawk. foot" leads to bias, and it is necessary to quickly pull the "tail" of the war hawk to force it to stop. Carrier arresting cables require carrier-based aircraft pilots to have more skilled flying skills.
