Penetrator for detecting extraterrestrial celestial body with atmospheric layer and solid surface

Abstract

The invention discloses a penetrator for detecting an extraterrestrial celestial body with an atmospheric layer and a solid surface, and belongs to the field of terrestrial planet detection. The penetrator comprises a penetrator inner core mechanism, a protective cover, a protective cover connecting and separating mechanism and a centroid adjusting mechanism; the penetrator inner core mechanism comprises a penetrating structure and a buffer energy absorption structure; the protective cover comprises an upper shell, a lower shell, a front pneumatic control surface and a rear pneumatic control surface. According to the protective cover connecting and separating mechanism, a motor drives the gear to rotate, the locking rod on the gear slides in the sliding rail on the driving locking piece, and therefore connection and separation of the mechanism are achieved. The centroid adjusting mechanism is composed of eight ball screw electric telescopic rods, and the position of the inner core of the penetrator is adjusted through different telescopic combinations of the rods, so that centroid transformation of the whole penetrator is achieved, and good initial penetration conditions are created for the penetrator. According to the invention, integrated detection of entry, deceleration and penetration of terrestrial planets such as Ganymede / Triton and the like can be realized.

Description

technical field [0001] The invention relates to the field of terrestrial planet detection, in particular to a terrestrial planet depth detection penetrator. Background technique [0002] In recent years, with the rapid development of deep space exploration technology, human beings have expanded the detection targets to some more far-reaching celestial bodies on the basis of various means of detection of major near-Earth celestial bodies such as the moon and Mars, so as to further understand the various celestial bodies in the universe. Structural features and space environments of celestial bodies. Carrying out research on stars in ice giant star systems such as Jupiter, Uranus, and Triton is an important goal for exploring dark matter, extraterrestrial oceans, and extraterrestrial nitrogen elements, and is an important carrier for studying the origin of the solar system and the evolution of life. [0003] At present, lander detection is a method of celestial body detection...

AI Technical Summary

Problems solved by technology

[0005] At present, domestic and foreign researches on surface high-speed impact penetrating probes have achieved certain results in the fields of target celestial body orbiting and landing, but there is a lack of in-depth research on the survival of penetrators after impact, specifically for Ganymede and Triton The research on the specificity of the entry stage of this kind of target star with an atmosphere is even less reported

Moreover, conventional penetrators achieve energy management through reverse thrust rockets during the entry phase, but the reverse thrust reduction in the atmospheric environment is complex, and the thermal protection and deceleration schemes for penetrators facing the atmospheric environment need to be studied
