Spacecraft heliocentric ellipse suspension track design method based on solar sail propulsion technology

Abstract

The invention provides a spacecraft heliocentric ellipse suspension track design method based on the solar sail propulsion technology. The method comprises the steps that the characteristics of track suspension height are analyzed, and the suspension height is decomposed into the suspension height with a constant value, and the suspension height changing in direct proportion to the sun-planet distance; on the basis, a track dynamic model of a solar sail spacecraft under a rotation inconsistent fit coordinate system is established, conditions for forming a heliocentric ellipse suspension track are given according to the balance of a two-level dynamic model, the balance conditions are met by controlling posture changes of a solar sail and changes of reflectivity, and then the heliocentric ellipse suspension track of the solar sail is obtained. The spacecraft heliocentric ellipse suspension track design method based on the solar sail propulsion technology provides a worthy reference general method for heliocentric ellipse suspension track design based on the solar sail propulsion technology.

Description

【Technical field】 [0001] The invention relates to the field of aerospace, in particular to a general method for designing a heliocentric elliptical suspension orbit of a spacecraft. 【Background technique】 [0002] After entering the 21st century, with the development of aerospace technology and material technology, advanced propulsion technology has shown a trend of vigorous development. Advanced propulsion systems such as solar sail propulsion devices and electric propulsion devices have become the most promising propulsion technologies for space missions due to their advantages of relying on solar light pressure and not consuming chemical fuels. Space agencies such as JAXA\NASA have carried out space verification experiments on this. In 2010, Japan's IKAROS project successfully sent a solar sail spacecraft into space for the first time, which officially opened the prelude to the use of solar sails to propel spacecraft. Since solar sail propulsion technology does not need...

Problems solved by technology

However, some planets orbit the sun in an elliptical motion. In order to realize real-time observation of their pole regions, it is necessary to study the heliocentric elliptical suspension orbit. Currently, the research on this type of orbit modeling method is limited, and this type of orbit is difficult to realize.
