METHOD OF AIR THERMAL CONDITIONING OF SPACE VEHICLE MODULES DURING GROUND TESTING AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: rocket engineering.;SUBSTANCE: group of inventions refers to equipment for ground testing of rocket and space equipment. Method of air thermal conditioning of space vehicles (SV) modules includes air blast from the environment, its cooling, drying, heating and supplying to thermal control module of space vehicle. In process of air blast, air temperatures at inlet and outlet of supplier are measured at different set air flow rates, volume air heating in supplier are determined. After cooling and drying, air inside heat-sound-insulated zone is heated to desired temperature. Device for air thermal conditioning of space vehicle modules includes a body, an airtight partition, dividing body into two zones – refrigerating and heat-sound-insulated. In the heat-sound-insulated zone of upper part of body there is a cooler-air drier with condensate discharge line, an air heater, an air pump with regulated speed, and air temperature sensors at inlet and outlet. In cooling zone there are an air-cooled condenser, a refrigeration compressor and an expansion device.;EFFECT: group of inventions technical result is higher the energy efficiency of thermal conditioning.;2 cl, 1 dwg
