METHOD simulate the heat flux for ground testing of thermal modes SPACECRAFT

摘要

Method for simulating external thermal fluxes for ground testing thermal spacecraft modes, comprising the steps that put the spacecraft in thermal vacuum chamber krioekranami, evacuated chamber quenched krioekrany to simulate cold space environment and subjected spacecraft exposed to the thermal fluxes from the simulator external thermal fluxes thermal vacuum chambers, characterized in that the spacecraft to a thermal vacuum chamber space reproduce heat flow , Simulator external thermal fluxes, feeding alternating voltage to each heating element simulator external thermal fluxes and continuously measuring the power consumption in the heating elements, fixed abrupt increase of power consumption in the heating elements relative to the power of the heating elements in the stationary heating mode cull heating elements, which are characterized by the above-mentioned power jumps, warm krioekrany, vented thermovacuum kama y replace the rejected heating elements, repeat the operations of rejection and replacement of the heating elements to achieve all the heating elements of a stationary heating mode, and then establish a spacecraft in thermal vacuum chamber and affect the spacecraft heat flows from the simulator external thermal fluxes, simulating vacuum and temperature flight regimes .
