Fuel-free spacecraft propelling system based on spatial atomic oxygen and propelling method

Abstract

A fuel-free spacecraft propelling system based on spatial atomic oxygen comprises an outer cylinder of a propelling device and an atomic oxygen collecting device. Two ends of the outer cylinder are open, the atomic oxygen collecting device is arranged at the front end of the outer cylinder propelling forwards and is hermetically connected with a radio frequency generating device and an ion cyclotron wave heating device through a magnetic confinement device, a spiral wave discharge oxygen plasma inlet and a spiral wave discharge oxygen plasma outlet in the ion cyclotron wave heating device are respectively provided with another magnetic confinement device, the atomic oxygen collecting device is used for pressurizing the spatial atomic oxygen entering the front end of the outer cylinder of the propelling device, the pressurized spatial atomic oxygen is ionized in a spiral wave discharge mode in the radio frequency generating device, the kinetic energy of oxygen ions in ionized oxygen plasma is increased in the ion cyclotron wave heating device, magnetic field configuration of a sprayer is changed by adjusting the magnetic confinement devices in the ion cyclotron wave heating device, accordingly, circumferential movement of the oxygen ions is transformed into parallel movement, and propelling force is provided for the spacecraft after the oxygen ions are sprayed out of the sprayer. Compared with the traditional fuel-borne electric propulsion technology, the fuel-free spacecraft propelling system using spatial environment particles does not need to carry working media and enables a spacecraft to work on an orbit in the whole life cycle.

technical field [0001] The invention relates to the technical field of spacecraft propulsion and space environment utilization, in particular to a fuel-free propulsion system using space atomic oxygen to propel an on-board spacecraft and a propulsion method for using the system to propel the on-board spacecraft to constant motion. Background technique [0002] Space propulsion technology can generally be divided into chemical propulsion, electric propulsion, and some other propulsion technologies (such as solar sails, tethered propulsion, etc.). At present, the main propulsion of most aircraft adopts chemical propulsion. As an advanced propulsion technology, electric propulsion is getting more and more attention. [0003] Chemical propulsion is a propulsion technology that uses chemical energy to send a spacecraft into a predetermined space orbit and achieve on-orbit maneuvering. The most prominent feature of chemical propulsion is that it can provide high thrust, and it h...

Problems solved by technology

[0006] Therefore, the problem solved by the present invention is that the launch cost of the existing fuel-carrying spacecraft propulsion method is high, and the on-orbit life of the spacecraft mainly depends on the amount of fuel carried, which leads to the limited problem of the spacecraft’s on-orbit life.
