Small-surface-source high-temperature blackbody source suitable for low-cold vacuum environment

Abstract

The invention aims at solving a defect that a high-temperature blackbody source under environmental parameters of typical space environment simulation equipment lacks a general solution in the prior art, and provides a small-surface-source high-temperature blackbody source suitable for a low-cold vacuum environment. The small-surface-source high-temperature blackbody source comprises a pyrolytic graphite heating core element, a power supply loop and a multilayer radiation screen heat insulation system, wherein the pyrolytic graphite heating core element and the power supply loop are arranged in the multilayer radiation screen heat insulation system; the power supply loop is used for heating the pyrolytic graphite heating core element in order to make the pyrolytic graphite heating core element generate heat radiation; and the multilayer radiation screen heat insulation system is used for forming a closed thermal environment inside the blackbody radiation source. The small-surface-source high-temperature blackbody source is suitable for target illumination of a semi-physical simulation system.

Description

technical field [0001] The invention relates to the field of space infrared light environment simulation, in particular to a small surface source high-temperature blackbody source adapted to a low-cold vacuum environment. Background technique [0002] With the development of infrared technology, infrared homing guidance technology has become one of the core technologies in the field of contemporary national defense and military. With the demand of hardware-in-the-loop simulation system in the development of missile weapons, infrared target and environment simulation technology has emerged. In recent years, many weapon systems need to work in a low-cold vacuum space environment. In order to make the simulation as close as possible to the real environment, the hardware-in-the-loop simulation system for simulating targets also needs to work in a low-cold vacuum environment. [0003] The environmental parameters provided by typical space ring mold equipment are: the absolute bac...
