7-phase multistage linear induced electromagnetic propeller

Abstract

A 7-phase multistage linear induced electromagnetic propeller comprises a driving coil, an armature, pulse power supplies and a charger. The driving coil is formed by a plurality of double-pancakes which are coaxially arranged on an insulation skeleton and is divided into multiple stages. Each stage of the driving coil is externally connected to one group of the pulse power supplies. A single-phase power supply in one group of the pulse power supplies is formed by one pulse capacitor and one discharging switch. One charger charges the capacitors of all the pulse power supplies. The multistage driving coils are coaxially arranged on one insulating sleeve and are fixed. The armature is placed in a first stage driving coil. The armature forges ahead linearly in the driving coil under an electromagnetic force effect. The armature accelerates from the first stage driving coil. When the armature arrives at a position of a next stage driving coil, the pulse power supplies which are externally connected to the stage driving coil begin to discharge. And the armature continuously forges ahead.

Description

technical field [0001] The invention relates to an electromagnetic thruster, in particular to a 7-phase multi-stage linear induction electromagnetic thruster. Background technique [0002] An electromagnetic thruster is a device that converts electrical energy into kinetic energy. Electromagnetic propulsion uses electromagnetic force to push objects to accelerate, theoretically there is no limit to the maximum speed, and it can reach a very high exit speed. According to the structure and working principle of the electromagnetic propulsion device, it can be divided into the following types: orbital type, synchronous coil type, reconnection type, helical coil type, linear induction type, etc. The linear induction electromagnetic thruster evolved from the principle of a 3-phase linear induction motor. Polytechnic University in the United States has mainly conducted a series of theoretical and experimental research on multi-stage linear induction electromagnetic thrusters powe...

This increases the difficulty of remote control and operation of the charging power supply. When there are many stages, too many voltage levels need to be monitored, which increases the risk of high-voltage tests.

[0005] 2. The coil parameters are exactly the same, and the power frequency can only be adjusted by adjusting the capacitance parameters. As the armature speed increases, the power frequency increases, and the capacitance value of each stage decreases. In order to keep the total energy of each stage power supply equal, the capacitance The initial voltage value is getting higher and higher, which brings difficulty to the insulation design of the system
