Detector emission method employing force-borrow mechanism to select space detection target

Abstract

The invention relates to a method for emitting detector which can select the detected target via swing-by mechanism, belonging to the technique of deep space detecting rail transfer. It can solve the problems of approachability evaluation of detected target with long semi long axis or large eccentric rate. The inventive method comprises: calculating optimized dual impulse transfer track; selecting swing-by track type; and assembling the swing-by tracks. First calculating the optimized dual impulse transfer track from the target star to emitting star; using the emitting star as swing-by star; using the parameter of dual impulse transfer at the emitting star as the match parameter in swing-by flying; using the heliocentric large-ellipse orbit whose period is several times of the revolution period of emitting star and the deep space device at aphelion, to search for the emitting parameter of said match condition. The invention guides in the swing-by mechanism to realize the expansion of former dual impulse transfer, to improve the approachability of the target with long semi long axis or large eccentric rate.

Description

technical field [0001] The invention belongs to the technical field of transfer orbits for deep space exploration, and relates to a detector launch method for selecting an interstellar detection target by using a leverage mechanism. Background technique [0002] In the early 1990s, the space research units of the United States, the European Space Agency, Japan and other countries and institutions once again set off a deep space project aimed at deepening the understanding of the solar system, further exploring the mysteries of deep space, and revealing the law of the evolution of the universe. The climax of exploration activity. At this time, the focus of detection targets began to shift to the large number of asteroids and comets in the solar system, that is, those non-cooperative asteroids with small volume, light weight, irregular shape, unstable rotation characteristics, weak gravitational field and uneven distribution. Small celestial objects, as well as the eight majo...

AI Technical Summary

Problems solved by technology

Using these classic two-pulse transfer strategies, the evaluation results are that those small celestial bodies with orbits close to the Earth have good accessibility (the total velocity increment required to realize the rendezvous mission is small), and those with large scientific value , but the accessibility of small celestial bodies with large orbital semi-major axis or large eccentricity is very poor (the total speed increment and launch energy required to realize the rendezvous mission are very large, which has exceeded the current human technology can achieve Degree)
