A buffer heat insulation structure for penetrating detection of extraterrestrial celestial bodies

Abstract

The invention discloses a buffer heat insulation structure for penetrating detection of extraterrestrial celestial bodies, and belongs to the technical field of thermal control design of penetrating detectors for deep space exploration tasks. The buffer heat insulation structure includes: a penetrator housing, a load, and a leaf spring. An installation cavity is opened inside the penetrator housing, and a common connection is provided between the installation cavity and the outside of the penetrator housing. Clearance; the penetrator shell provides support for the load and the leaf spring. After the penetrator invades the low-temperature soil of an extraterrestrial body, the penetrator shell is in direct contact with the low-temperature soil. The buffer heat insulation structure for penetrating detection of extraterrestrial celestial bodies provided by the present invention reduces the internal load of the penetrator and the heat leakage between the shell as much as possible at the cost of small volume and weight, and can satisfy both buffer protection and Thermal insulation requirements to ensure that internal loads can work normally and reliably in extremely low temperature environments.

Description

technical field [0001] The invention relates to the technical field of thermal control design of penetrating detectors for deep space exploration missions, and more specifically relates to a buffer heat insulation structure for penetrating detection of extraterrestrial celestial bodies. Background technique [0002] The penetrator (penetrator, hereinafter referred to as the penetrator) is an effective means of in-situ detection of extraterrestrial celestial bodies. It uses the hard landing method to penetrate the surface soil of the celestial body to a certain depth at high speed and protect Survival of internal detection instruments under extremely high overload conditions for scientific detection. The penetrator is especially suitable for in-situ detection of the surface and subsurface of celestial bodies in areas where soft landing probes are difficult to reach. It has unique advantages of low cost and flexible application. For the detection of extraterrestrial objects s...

Problems solved by technology

Therefore, the coupling of extremely high overload and extremely low temperature, coupled with the strict constraints of the penetrator's own volume, weight, energy and other available resources, has brought severe challenges to the thermal control design of the penetrator.

However, due to the particular environmental conditions and resource constraints faced by the penetrator, the conventional means of spacecraft thermal control are often not suitable for the penetrator, and there is still a lack of buffer heat insulation for the penetrator's overload protection and heat leakage control Effective solution to meet the penetrator's survival under extreme force and heat conditions
