Hydraulic-electric combined space thruster

Abstract

The invention discloses a hydraulic-electric combined space thruster, comprising a combustion chamber, a catalyst, an insulator, an anode, a sprayer nozzle, a permanent magnet ring and a power supplysystem. Catalyst particles are filled in a combustion chamber. A circular through hole is formed between two end faces of the insulator, and the insulator is installed in the combustion chamber and ison downstream of the catalyst (along the flow direction of a propellant, the same below). Geometric profile of the anode is the same with that of the insulator, and the anode is installed in the combustion chamber and is on downstream of the insulator. The sprayer nozzle is connected with the tail of the combustion chamber. The permanent magnet ring is nested on the tail end outside the combustion chamber. The positive pole of the power supply system is connected with the anode, and a negative pole is connected with the catalyst. A liquid rocket engine and a plasma rocket engine are integrated in one hydraulic-electric combined space thruster, so that one engine has two working modes. When an aircraft executes low orbit tasks, the aircraft works by using a combustion propellant (chemicalenergy of the propellant is converted into kinetic energy). When the aircraft performs high-orbit or deep-space exploration missions, the aircraft uses plasma propulsion to work (converts kinetic energy of a power source into kinetic energy), so that one thruster can meet different mission requirements of the aircraft, thereby reducing total mass of a 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.
