Abstract

The invention discloses an electromagnetic propulsion device. The electromagnetic propulsion device comprises an electromagnetic railgun and a thermoelectric power generation device. The electromagnetic railgun comprises two launch trajectories and an armature which is arranged between the launch trajectories. The thermoelectric power generation device comprises cold end substrates, hot end substrates arranged on the launch trajectories and thermoelectric modules arranged between the cold end substrates and the hot end substrates. The hot end substrates are used for conducting heat of the launch trajectories. The cold end substrates are used for providing low-temperature cold sources. The thermoelectric modules are used for conversion between heat / cold and electric energy. According to the electromagnetic propulsion device, the thermoelectric power generation device is disposed on the electromagnetic railgun; the heat of the launch trajectories is conducted through the hot end substrates, so that the temperature of the launch trajectories is decreased and loss caused by overheating of the launch trajectories is prevented to a certain degree; meanwhile, the thermoelectric modules convert heat into electric energy, so that the electric energy conversion rate of the electromagnetic railgun is effectively increased.

Description

technical field

[0001] The invention belongs to the technical field of electromagnetic emission, and in particular relates to an electromagnetic propulsion device. Background technique

[0002] Electromagnetic rail gun is a new type of launching device that can accelerate projectiles to ultra-high speeds. It uses electromagnetic energy to drive projectiles into mechanical energy. This technology is also used to accelerate rockets, satellites, etc. The electromagnetic railgun consists of two parallel conductive rails, a high-power pulse power supply, a switch, and an armature with good contact conductivity. Compared with other launching devices, the electromagnetic railgun has a higher launch speed, a projectile with greater kinetic energy, fast response, and precise control. But the electromagnetic rail gun has the following problems now: 1. Low electric energy conversion efficiency, huge energy system, low energy utilization rate, improving energy utilization rate and redu...
