Embodiment Construction

[0035] The present invention will be further described below in conjunction with accompanying drawing.

[0036] Depend on image 3 As can be seen, the present invention provides a method for selecting a target star for manned asteroid detection, which comprises the following steps:

[0037] Step 1: Determine the constraints for the primary selection of the target star

[0038] The constraints for the primary selection of the target star are composed of asteroid orbital parameters, the asteroid's absolute magnitude, and the asteroid's spin period, and each part is in a parallel relationship.

[0039] The asteroid orbit parameters include the semi-major axis a, eccentricity e, and orbit inclination i of the asteroid orbit. It is determined by the carrying capacity of the launch vehicle and is the primary factor considered in the primary selection of the target star. In this example a min max , e1 ,e 2}, imin ,a max ,e 1 ,e 2 The calculation formula is

Abstract

The invention discloses a target asteroid selection method for manned asteroid exploration. The method comprises four steps as follows: Step 1: determining constraint conditions for target asteroid preliminary selection; Step 2: screening an asteroid data base according to the constraint conditions which are determined in Step 1 and used for target asteroid preliminary selection to obtain primarily-selected targets; Step 3: performing primarily-selected asteroid orbit design and related calculation, including design of task orbits, calculation of velocity increments, search of launch windows and calculation of task periods; Step 4: performing target asteroid optimization, including a target asteroid optimization model and solutions. The method involves a strict target asteroid preliminary selection process and a target asteroid optimization mathematical model, so that a target asteroid which has the project realizability and the exploration value can be provided.

Description

technical field [0001] The invention relates to a method for selecting a target star for manned asteroid exploration. Based on the method, target stars with both engineering feasibility and scientific value can be screened out, belonging to the technical field of aerospace. Background technique [0002] The manned exploration of asteroids has very important and special significance. Due to the subjective initiative of astronauts, they can carry out detection activities such as on-site investigation, arrangement of scientific instruments, sample collection and preliminary identification of samples, so they can better complete the asteroid detection mission. The selection of the target star is the primary problem and the key technology to be solved for manned asteroid exploration. Most of the existing methods for selecting target stars for manned asteroid exploration are only based on the asteroid’s orbital parameters, ignoring the asteroid’s physical characteristics, and the...
