Investigation of Insulation Effect on Thermal Control System of Remote Sensing Satellite
Session
Poster Session 4
Abstract
The thermal control system (TCS) is one of the main systems of spacecraft (SC). Its purpose is to maintain all the components of a spacecraft within their respective temperature limits. In general, the thermal control system is composed of two different types of systems the passive and active. Multilayer Layer Insulation (MLI) is the most common thermal-control elements on spacecraft. MLI is considered as a passive type. MLI blankets prevent both excessive heat loss from a component and excessive heating from environmental fluxes, rocket plumes, and other sources SC model in Low Earth Orbit (LEO) is created by thermal desktop program, in order to launch a parametric study to check design of thermal control elements ( Radiators , Heaters , MLI ) by calculating the temperature field along the equipment panel and verify that the maximum and minimum temperature of the lower sheet of the panel is within the design range of temperature from 0˚C up to 35 ̊C .Verifying the optimum selection of the power of heaters and the correct distribution of them along the panel zones is performed by increasing or decreasing the area of MLI on the upper sheet of the panel, which controls the amount of heat dissipation from SC.
