A penetrator for detection of extraterrestrial objects with atmosphere and solid surface

Abstract

The invention discloses a penetrator for detecting extraterrestrial celestial bodies with an atmosphere and a solid surface, belonging to the field of terrestrial planet detection. The penetrator comprises a penetrator core mechanism, a protective cover, and a protective cover connection and separation mechanism and the center of mass adjustment mechanism; the penetrator core mechanism includes a penetration structure and a buffer energy-absorbing structure; the shield includes upper and lower shells and front and rear pneumatic rudder surfaces; the shield connection and separation mechanism is driven by a motor to rotate a gear, and the gear The locking rod on the upper part slides in the sliding rail on the active lock piece, so as to realize the connection and separation of the mechanism; the center of mass adjustment mechanism is composed of eight ball-screw electric telescopic rods, and the different telescopic combinations of the rods are used to realize the adjustment. The position of the core of the penetrator is adjusted, so as to realize the transformation of the center of mass of the penetrator as a whole, and create a good initial penetration condition for the penetrator. The invention can realize the integrated detection of entry, deceleration and penetration of Ganymede / Triton and other terrestrial planets.

Description

technical field [0001] The invention relates to the field of terrestrial planet detection, in particular to a penetrator for depth detection of terrestrial planets. Background technique [0002] In recent years, with the rapid development of deep space exploration technology, human beings have expanded their 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 characteristics and space environment of celestial objects. Carrying out research covering Jupiter, Uranus, Triton and other ice giant star systems is an important goal to explore dark matter, extraterrestrial oceans, and extraterrestrial nitrogen elements, and an important carrier for studying the origin of the solar system and the evolution of life. [0003] At present, lander detection is a widely used method of celest...

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
