A posture correcting device for a Mars landing module

Abstract

The invention provides a device for centering postures of a Mars landing capsule. The device comprises a base plate (1), a support (2), a connecting shaft (3), a torsional spring (4), a centering ring (5) and a compressing and releasing device (6). Under the conditions that the size, the weight and the energy supply of the device are limited strictly, an initiating explosive device acts to release the compacted torsional spring, and therefore the centering ring is driven to center the postures of the Mars landing capsule. The device for centering the postures of the Mars landing capsule has the advantages of being simple in structure, safe, reliable, small in size and light in weight. As the effective means for guaranteeing the correct postures of the landing capsule on the Mars, the device for centering the postures of the Mars landing capsule can be directly applied to development for a landing capsule in the first Chinese Mars landing detecting task, and can also provide reference for design of Chinese follow-up small-scale planet landing capsules.

Description

technical field [0001] The invention relates to a Mars landing system, in particular to a posture correcting device for a Mars landing module. Background technique [0002] my country plans to launch a Mars global remote sensing probe in December 2015 to realize Mars orbiting and carry out Mars global remote sensing exploration; at the same time, it will carry out Mars landing verification missions to verify Mars entering deceleration landing related technologies. [0003] Due to the constraints of the launch window and the existing carrying capacity, the weight of the lander in the Mars global remote sensing probe is only 60kg, and the volume, weight, and energy of the built-in cylindrical landing capsule are strictly limited; at the same time, due to the topographical characteristics of the landing site And the landing process is uncertain, the initial landing attitude of the landing module may not meet the specified face-up attitude requirements, and later adjustments are...
