The invention belongs to space nuclear propulsion, micromass culture and vector Push Technology fields, specifically, the present invention relates to one
Type spherical structure High-precision Vector synthesize nuclear energy micro-thruster, be specially applied towards spacecraft, nuclear energy thrust face element
It synthesized by class football structure, switch the High-precision Vector thrust synthesis for carrying out size, open and-shut mode control by face element
Propulsion system.
Background technique
In recent years, continue deeply with the continuous development of space science and technology and space exploration, the power of spacecraft
Source category gradually enriches, and the dynamical system of Cong Weiniu magnitude to thousand Ns or more, form regulation system emerges one after another, matched
Propulsion device also gradually produces many changes and innovation in continuous practice.
Currently, there are many type of advanced propulsion in the world, existing advanced electric propulsion has nearly ten kinds of schemes, relates to that grind unit wide
General, maturity is different, and non-electric propulsion also has many schemes, such as: microwave/laser (being collectively referred to as energy beam) propulsion, fusion, electric sail, gold
Belong to hydrogen, high nitrogen compound, antimatter, fission fragment propulsion etc..These advanced propulsions are much in the stage of TRL < 3, advanced propulsion
Area research is also very insufficient.
Nuclear propulsion is one of the forward position of the advanced Push Technology of spacecraft.In various advanced propulsions, nuclear energy has energy
The feature that density is high, the service life is long, specific impulse is big is advanced one of the forward position for promoting research and development, and NASA is in " future space technology way for development
Line " and " 30 key technologies ", which are all mentioned, will greatly develop advanced nuclear propulsion.Currently, the focus of nuclear propulsion almost encloses
It is wound on nuclear heat propulsion, core is a fission-type reactor, and other nuclear propulsions belong to and there is no enough technical supports other than fissioning
Advanced concept, such as nuclear fusion, anti-physics and fission fragment etc..Nuclear heat propulsion based on fission is also at the starting stage, international
Upper nuclear fission is applied to space propultion also in theoretical and experimental study stage (mainly the United States, Russia), and the country there is no relevant sky
Between test.The maximum difficulty of nuclear fission heap is to minimize, and is limited, cannot reach at present cube by fission critical size
Quality within rice volume below, ton, and it is not suitable with miniaturized application.
Another hot spot direction of propulsion system is micromass culture, and micro-thruster refers generally to micro- ox pushing away to newton magnitude thrust
Into device.In Astro Recon meeting summarize in the recent period it is most mature, be expected to become promote mainly into micromass culture there are three types of: iodine Hall electricity pushes away
