Buffering and heat-insulating structure for extraterrestrial celestial body penetration type detection

Abstract

The invention discloses a buffering and heat-insulating structure for extraterrestrial celestial body penetration type detection, which belongs to the technical field of deep space detection task penetration type detector thermal control design. The buffering and heat-insulating structure comprises a penetrator shell, a load and a plate spring, a mounting cavity is formed in the penetrator shell,and a gap communicated with the mounting cavity is formed between the mounting cavity and the exterior of the penetrator shell; the penetrator shell provides support for the load and the plate spring,and after the penetrator invades the low-temperature soil of the extraterrestrial celestial body, the penetrator shell makes direct contact with the low-temperature soil. According to the buffering and heat-insulating structure for extraterrestrial celestial body penetration type detection, heat leakage between the internal load of the penetrator and the shell is reduced as much as possible withthe small size and weight cost, the requirements for buffer protection and heat insulation can be met at the same time, and the internal load can normally and reliably work in the extremely-low-temperature environment.

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
