Problems solved by technology

Among them, the thrust of the launch vehicle mainly comes from the energy conversion of the propellant. According to the type of propellant, it can be divided into: liquid rocket propulsion and solid rocket propulsion. While these two technologies obtain high thrust, some disadvantages are also exposed. Environmental hazards caused by high temperature ablative materials, toxic and harmful or even highly toxic discharges, single-use and low fuel controllability (such as solid propellants), etc.
Electric propulsion technology is widely used in the propulsion, deceleration and attitude adjustment of small and medium-sized products in near-earth and deep space exploration due to its characteristics of small thrust, repeatable ignition, and long battery life. seem powerless

Abstract

The invention discloses a propelling method and a propelling device for liquid-phase carbon dioxide phase change based on high-voltage discharge. The method comprises the following steps that carbon dioxide is contained in a heat insulation container in a liquid phase form, high-voltage discharge is carried out in the liquid-phase carbon dioxide to generate plasma to be instantly heated so that the carbon dioxide can be converted into a gas phase from a liquid phase, and carbon dioxide gas obtained after phase change is jetted by a preset jetting amount in the preset direction to obtain thrust.

Description

Technical field [0001] The invention belongs to the technical field of aerospace and extraterrestrial exploration and propulsion, in particular to a propulsion method and propulsion device for a liquid phase carbon dioxide phase change based on high-voltage discharge. Background technique [0002] In recent years, with the rapid development of extraterrestrial detection technology, the demand for exploration, development and utilization of extraterrestrial resources has become more and more vigorous. In extraterrestrial exploration, propulsion technology is the basic guarantee for the transportation of various aircraft.
