Description

technical field [0001] The invention relates to the technical field of electric propulsion, in particular to an electromagnetic induction plasma accelerator. Background technique [0002] A variety of engineering applications need to realize the generation of plasma and accelerate it. Typical applications include plasma spraying, surface processing, or propulsion systems in aerospace. [0003] In the field of aerospace, the propulsion device, as the part that provides power, is extremely important to the spacecraft and is the basis for the spacecraft to complete its mission. Compared with traditional chemical propulsion, electric propulsion accelerates the propellant through electric energy to obtain thrust, and its propulsion energy comes from outside the propellant, which can obtain a higher jet velocity, thus effectively reducing the consumption of propellant and increasing the effective efficiency of the spacecraft. load. At present, electric propulsion technology has...

AI Technical Summary

Problems solved by technology

Take the typical situation of various core components in the United States as an example, in which the life of the discharge capacitor can reach 10 7 times, the discharge switch can reach 10 5 times, but the life of a typical pulse gas valve is only 10 3 Second, it greatly restricts the practical application of this type of device

[0009] 2. Power consumption problem

The spool of the valve switches between stationary-high-speed movement-static state at high speed, a large part of energy will have to be consumed in the braking of the spool, so a large extra power is required to drive the valve to work, which causes While reducing system efficiency, it also brings problems such as heat dissipation and system complexity

[0010] 3. Interference problem

There is an electrical connection between the drive device of the valve and the drive circuit of the excitation coil group, which may cause mutual interference between the two, or even malfunction of the valve.
