Embodiment Construction

[0033] A design method for a spaceship to return to a predetermined landing point and return orbit, which is to realize the sub-satellite point accurately passing through the predetermined landing point by selecting the average anomaly angle of the orbit, adjust the semi-major axis of the orbit to make the orbit meet the regression characteristics, and establish the semi-major axis of the orbit and the orbital level The double-layer iterative solution process of the two parameters of the anomaly angle obtains the matching design parameters of the orbital inclination, the semi-major axis of the orbit, and the mean anomaly of the orbit to ensure that the sub-satellite trajectory of the spacecraft accurately passes through the predetermined landing point every return cycle.

[0034] The method comprises the steps of:

[0035] Step 1. Establish an algorithm for the sub-satellite point to pass through the predetermined landing point

[0036] Consider the Earth's gravitational pertu...

Abstract

The invention provides a design method for an airship returning back to a predetermined fall point recursive orbit. According to the design method for the airship returning back to the predetermined fall point recursive orbit, a sub-satellite point can accurately pass a predetermined fall point by selecting a rail mean anomaly, a rail satisfies recursive characteristics by adjusting the rail semi major axis, a double-layer iteration solution process for two parameters of the rail semi major axis and the rail mean anomaly is established, design parameters which are mutually matched with the rail inclination angle, the rail semi major axis and the rail mean anomaly are obtained, and an airship sub-satellite point track is guaranteed accurately passing through the predetermined fall point at every recursive period.

Description

Technical field: [0001] The invention relates to the technical field of aircraft track design, in particular to a method for designing a return track of a spaceship returning to a predetermined landing point. Background technique [0002] In order to ensure that the manned spacecraft can provide astronauts with the opportunity to return to the domestic scheduled landing site every day, the orbit design of the manned spacecraft in my country’s manned spaceflight project has always followed the design principle of the return orbit. The manned flight of the first phase of the project and the rendezvous and docking of the second phase of the project The manned spacecraft used is 2 days to return to orbit. In the third phase of the space laboratory and space station project, the orbital height and orbital inclination of the manned spacecraft have changed compared with the first and second phase projects. The spacecraft of the third phase of the project plans to return to orbit in...
