A hydraulic-electric combined space thruster

Abstract

The invention discloses a liquid-electric combination space thruster, which comprises a combustion chamber, a catalyst, an insulator, an anode, a nozzle, a permanent magnet ring and a power supply system. The catalyst particles are filled inside the combustion chamber; a circular through hole is opened between the two end faces of the insulator, and installed in the combustion chamber, located downstream of the catalyst (along the flow direction of the propellant, the same below); the geometric shape of the anode and the insulator The same, and installed in the combustion chamber, located downstream of the insulator; the nozzle is connected to the tail of the combustion chamber; the permanent magnet ring is nested at the outer tail of the combustion chamber; the positive pole of the power supply system is connected to the anode, and the negative pole is connected to the catalyst . The present invention integrates the liquid rocket engine and the plasma rocket engine into a liquid-electric combined space thruster, so that one engine has two working modes, and the aircraft uses the mode of burning propellant to work when performing low-orbit missions (the propulsion The chemical energy of the agent is converted into kinetic energy), and the aircraft uses plasma propulsion when performing high-orbit or deep-space exploration missions (converting the kinetic energy of the power supply into kinetic energy), so that one thruster can meet the needs of different missions of the aircraft, thereby reducing the total mass of the spacecraft.

Description

technical field [0001] The invention relates to the technical field of spacecraft engines, in particular to a combined hydraulic-electric space thruster for aircraft attitude and orbit control. Background technique [0002] Since October 4, 1957, when the former Soviet Union launched the first artificial earth satellite, human beings have never stopped exploring space. From the Apollo moon landing program to the Curiosity Mars rover, from the International Space Station to Tiangong-2, scientists from all over the world have explored this mysterious universe with continuous innovation. [0003] The rapid development of the aerospace industry is inseparable from the support of space propulsion technology. After decades of development, space propulsion technology can basically meet the needs of various space missions. As a technology developed on the basis of rocket propulsion, space propulsion can be divided into four categories according to the nature of the mission: launch,...

Problems solved by technology

However, as a branch of the plasma thruster, the thrust provided by this type of thruster is on the order of micronewtons, which cannot meet the requirements of low-orbit missions.
