Abstract

The invention relates to a planning method for a spacecraft reentry return orbit. The planning method comprises the steps that a, the reentering point position and speed of the spacecraft reentry return orbit are determined; b, the parameter variable of planning of the return orbit is determined; c, a return orbit planning equation is established; d, the return orbit is calculated; e, the heelingangle time curve is calculated; f, reentry overload of the spacecraft reentry return orbit is planned; and g, the step a to the step f are repeated, and the spacecraft return orbit is solved in an iteration mode. According to the planning method for the spacecraft reentry return orbit, the return orbit of a spacecraft can be designed quickly by adopting the planning method, and a certain referencevalue for return orbit design of near-ground orbit return and deep space jump return is achieved.

Description

technical field [0001] The invention relates to a return orbit planning method for high-speed reentry of a spacecraft. Background technique [0002] Return refers to the process that the spacecraft enters the earth's atmosphere along its orbit or transition orbit after orbit change, decelerates and lands under the action of aerodynamic force. The trajectory of the spacecraft during the return process is called the return trajectory. The return orbit of a near-Earth spacecraft can be divided into an attitude adjustment section, a braking section, a taxiing section, a re-entry section, and a landing section. The dynamic models used in each section are different, and the calculation process is relatively complicated. During the return process of the spacecraft, high-speed re-entry leads to serious aerodynamic heating and harsh environment. The deceleration overload during re-entry, heat flow and total heat absorption caused by aerodynamic heating, and landing accuracy are all ...
