A deep space high-speed impactor graded low-power thermal control method

Abstract

A thermal control method for deep-space high-speed impactors with hierarchical low power consumption. The impactor (2) works sequentially in the cruise flight segment, autonomous flight segment, and post-collision survival segment; wherein in the cruise flight segment, the impactor (2) is installed in the surrounding on the impactor (1); the impactor (2) includes a highly integrated module (3), a propulsion module (4), an impactor body (6), and a high reinforcement module (7), wherein the high reinforcement module (7) is installed on the impactor In the main body (6); in the cruising flight section, the orbiter supplies power and heat to the high integration module (3), the propulsion module (4), and the impactor body (6); in the autonomous flight section, the high integration module (3) The battery supplies power and heats the highly integrated module (3), the propulsion module (4) and the highly reinforced module (7); during the post-collision survival stage, the battery in the highly reinforced module (7) supplies and heats the electronic equipment (8). The method of the invention can meet the temperature control requirements of low power consumption at each stage during the impactor mission.

Description

Technical field [0001] The present invention relates to a depth low-air high speed impact, which belongs to deep space detection aircraft thermal control technology. Background technique [0002] Deep-air high-speed impact detection is an important means of detecting the internal detection of the celestial body. In the impact mission, the impactor is mounted into the outer space environment by the detector. After the detector is close to the target celestial body, the impactor is separated from the detector through the autonomous flight impact target celestial body and invaded into the target celestial body, and the impactor will Maintain long-term survival detection for a certain period of time. During the whole process, if the impactor does not make any protection, it will be directly exposed to an outer space deep cooling environment, and its internal electronic devices will not work and lead to the failure of the task. Therefore, the thermal control design of the impactor is ...
