The principle of the motor of the invention is that the motor shell (stator) is made into a long structure with a groove, and the inner surface of the structure is provided with a coil, thus the motor becomes a straight linear motor, and a strip-shaped rectangular steel rail is used as a sliding steel support groove of the straight linear motor. The linear motor can slide upwards to drag the fighter to take off.)

1. The electromagnetic catapult for aircraft carrier is a linear motor based on the principle of motor, and has protecting box and pulleys on two sides.

2. The pulleys slide on the special steel rails and are arranged on two sides of the protection box to help the pulleys slide in the sliding grooves, so that the linear motor works normally.

3. The steel rail is a special steel rail, and is provided with grooves on two sides and a large square hole and a small square hole in the middle.

4.380-400V alternating current and 50 wave current are added with a frequency regulator to regulate the speed of the frequency change linear motor.

(I) technical field

The invention belongs to a special purpose for large-tonnage ships, such as aircraft carriers, sailing on water.

(II) background of the invention

With the continuous development of science and technology, only American aircraft carriers in the world use ejection devices, also called ejectors, and the shape takeoff fighters using a slide device (with arc-shaped upward tilting slopes for the heads of the ships) in other countries comprise two aircraft carriers currently used in China. Its disadvantages are slow take-off speed, high oil quantity, short flying time, and influence on attack range … ….

Disclosure of the invention

The invention utilizes the principle of a motor and the motor is a circular shell also called as a stator, the inner surface of the motor is provided with a coil winding (the circular shell is sawn and pulled into a long strip to be straight), which is a linear motor, for example, the motor is made into a long groove and provided with a coil winding to be a long strip in actual production, and the motor can slide on a special long strip steel rail to be called as a rotor, thus solving the combination, ensuring that the flying speed of the fighter is high, the good oil quantity is small, the fighter flies far, and enhancing the attack range … … and the like.

Detailed Description

The invention relates to an operation step of an aircraft carrier magnetic catapult, which comprises the following steps: the barrier plate is placed flat, the fighter is dragged to the flying line for parking, the trailer is separated from the placeable place, various switches are turned on, the slow-adjustment push stay rod is close to a front wheel pillar 9 of the fighter (originally lifted), all the just-in-sequence fighters start to press a linear motor button, the fighter flies fast to leave an aircraft carrier catapult, and at the moment, the linear motor is jacked to a power switch for stopping; the linear motor moves back to the original position on the sloping steel rail (because the linear motor has weight and moves back to have a downward slope). The warplane is successfully ejected out for the first time, and the warplane is not worried to be ejected successfully again.
