Graded low-power-consumption thermal control method of deep-space high-speed impactor

Abstract

The invention discloses a graded low-power-consumption thermal control method of a deep-space high-speed impactor. The impactor (2) sequentially works in a cruise flight section, an autonomous flightsection and an after-impact survival section. In the cruise flight section, the impactor (2) is mounted on a surrounding device (1); the impactor (2) comprises a high-integration module (3), a propelling module (4), an impactor body (6) and a high-reinforcement module (7), wherein the high-reinforcement module (7) is mounted in the impactor body (6); in the cruise flight section, the surrounding device supplies power to and heats the high-integration module (3), the propelling module (4) and the impactor body (6); in the autonomous flight section, a battery in the high-integration module (3) supplies power to and heats the high-integration module (3), the propelling module (4) and the high-reinforcement module (7); and in the after-impact survival section, the battery in the high reinforcing module (7) supplies power to electronic equipment (8) for heating. According to the method, a low-power-consumption temperature control requirement of all stages in an impactor task period can be met.

Description

technical field [0001] The invention relates to a thermal control method with graded low power consumption for a high-speed impactor in deep space, and belongs to the technical field of thermal control of deep space exploration aircraft. Background technique [0002] The detection of high-speed impacts in deep space is an important means of detecting the interior of celestial bodies. In the impact mission, the impactor is carried by the probe into the outer space environment. After the probe is close to hitting the target celestial body, the impactor and the probe will separate and hit the target celestial body through autonomous flight and penetrate into the interior of the target celestial body. After that, the impactor will Keep a long-term survival probe for a certain period of time. During the whole process, if the impactor does not provide any protection, it will be directly exposed to the deep and cold environment of outer space, and the electronic equipment inside i...
