Abstract

An electromagnetic plasma propeller based on electromagnetic propulsion principle different from the gas propulsion principle features that the charged particles (plasma) are accelerated by electrostatic linear accelerator. Said charged particle is such obtained that the alkali metal and its salt (such as KCD3) is vaporized and electroionized under high temp of gas and the gas can generate strong plasma stream under high temp and pressure. Said plasma stream is accelerated by electromagnetic force.

Description

Plasma electromagnetic thruster.

The invention belongs to the technical field of: rocket propulsion technology.

A plasma (gaseous substance) is a solid body that can be propelled by electromagnetic forces. The plasma is propelled by electromagnetic forces, and the solid matter is propelled by the plasma. The solid body to be launched is internally provided, so that plasma can be generated, such as fuel of a rocket. An electromagnetic force generator is arranged in the plasma body, so that the plasma body to be emitted is an emitter with emitting capability, and the power of the emitter is derived from the propulsion of the plasma body by the electromagnetic force. The plasma is ejected by the electromagnetic force, and the reaction force acts on the emitter, so that the plasma is propelled by the electromagnetic force.

Fig. 1 is a structural arrangement diagram of a plasma thruster. A is a cross-sectional view of the open type plasma accelerator. G is a pair of accelerating electric plates, each pair is powered by a pair of discharging plates of the plasma igniter patent, and six pairs of accelerating electrodes are powered by six pairs of high-voltage generators of the plasma igniter patent. In between it is resistant to electricityAnd insulating ceramic magnetic phase at high temperature. The electrode is made into a half-moon-shaped hollow shape, accelerated plasma is forced outwards due to the action of electromagnetic force, and the half-moon-shaped electrode can contain more space charges by utilizing the phenomenon. D is a plasma generator in which the high-temperature, high-pressure fuel gas is added with an additive, such as KCO₃And alkali metals and cesium Cs susceptible to thermal ionization, i.e. addition of seed S_eeding. The gas is better increased in conductivity. C is the power supply part of the accelerating electrode, and the key point is the cascade circuit structure for realizing high-power multiple pairs of spark discharge, which is more clearly described in the cited document. E is the connecting line of the power supply to the acceleration electrode.

Fig. 2 illustrates the propulsion principle. G is two half-moon accelerating electrodes, and the plasma forms a power-on loop of the two electrodes G through D and C direct currents. Therefore, the accelerating electrode is connected with D, C power supply forms a loop with current I, and the plasma is stressed in the direction F.

F magnetic = gV₁×B/c

g is the charge of the plasma-the charge of the force.

C is the speed of light

V₁The moving speed of plasma is represented by the magnetic field intensity of vector B and V₁The vector product of (a), which is intuitively illustrated in fig. 2.

The final product of combustion is carbon dioxide and water. It seems simple, but the charging mechanism of combustion, with the formation of the end product, cannot be explained convincingly, and in fact there are many intermediate processes from the beginning to the end. Such as: it was found by instrumentation that during combustion, the most abundant ion present was H₃And O. And there are also very short-lived ions that are not easily detected, indicating intermediate processes, and not a problem that could convincingly be explained by the theory of starting and ending combustion processes.

The research shows that: where the chemical reaction is most vigorous, i.e., where chemical ionization is most active. … there is little chemical ionization in the subsequent combustion gases. The literature indicates that the most convincing way of performing chemical ionization may be:

this is an expression for the intermediate process of combustion of hydrocarbons in air.

In fact, this patent aims to be able to produce a large quantity of conductive gas, i.e. to increase the conductivity of the combustion gas. Adding easily ionizable alkali metal, such as Cs, and its salt, such as KCO₃These are methods for increasing the conductivity of the combustion gases- -the production of conductive gases in the plasma state.

The accelerating voltage comes from a high-voltage power supply of instantaneous discharge. By utilizing the structural scheme of the patent, the thrust is generated, the thrust is theoretically calculated at the light speed, and unlike a gas rocket, the transmission and reaction speed and the electromagnetic force of the thrust are completely different from those of the Japanese language in the light speed transmission and reaction.

The missile is propelled by gas at a speed of more than 7.5Km/sec, and can reach a high speed within hundreds of kilometers per second if being propelled by electromagnetic force. The electromagnetic propulsion theoretical speed is the speed of light. Generally, the acceleration of a missile propelled by a jet rocket is only in the order of 10 ten thousand g, while the electromagnetic propulsion can reach the order of hundreds of thousands of g and 100 ten thousand g. The burst force of the general electromagnetic propulsion is far greater than that of a rocket propelled by gas injection, the time for reaching the maximum speed is the fastest for several seconds, and the time is generally dozens of seconds to more than one hundred seconds. … these are all performance advantages of electromagnetic propulsion launch and conventional gas jet propulsion with this patent application.

The combined force of gas injection and electromagnetic propulsion technologies will achieve the goal of greater speed in a more economical manner. Therefore, the electromagnetic propulsion technology breaks through the natural pattern of the gas jet technology, and the electromagnetic projection is better than the original projection technology and is a new situation. It is also not a self-evident reason that this technique can be imagined to have a great impact on national defense and economy.

The key technology is only two points: a plasma generator, which is also a mature technology in the aspects of gas ignition and seed adding technology. The second point is a plasma accelerator, which works by applying instantaneous high voltage to two parallel conductors, and the key point is an energy storage and release structure for generating instantaneous high voltage, wherein, capacitors are charged in parallel, and the principle of series discharge enables the capacitors to store energy, so that instantaneous high current and high voltage are obtained, and large energy is released to accelerate plasma. This technique of generating a high power transient discharge has been described in the patent plasma igniter, application No. 98107220.8, applicant: details of the disclosure in the patent application of wangshi are not repeated.

There are attached drawings.

From the structural point of view, it is preferable that the ramjet engine is used as a plasma gas supply, and the exhaust port is preferably a structure in which an electromagnetic thrust is applied to a high-temperature-resistant conductive rail made of parallel insulating graphite.
