A small penetrator for planetary surface soil penetration detection

Abstract

This invention discloses a small penetrator for planetary surface penetration detection. The penetrator includes a penetration buffer module, a power module, a moving penetration module, and a communication antenna module. The penetration buffer module uses an aluminum honeycomb structure and a rigid plate to buffer and reduce the impact on the payload. The power module provides torque via a servo motor and a drive shaft to drive the moving penetration module for secondary penetration. The moving penetration module, through the cooperation of an inner sleeve, an outer sleeve, and the payload module, achieves downward linear penetration and stroke self-locking. The communication antenna module integrates a fixed claw and a spiral rising structure, using a motor drive to achieve the deployment of the fixed claw (anti-reaction force ejection) and the secondary spiral deployment of the communication antenna. This invention features a compact structure, low weight, low cost, and high reliability. It can be deployed at multiple points, adapting to the needs of planetary surface penetration detection and solving the problems of insufficient payload protection, weak secondary penetration capability, and difficulties in fixed ballistic protection and antenna deployment in existing penetrators.
