기판에 부착된 인공위성용 필름 히터의 성능 및 온도 변화 특성 = Performance and Temperature Change Characteristics of a Film Heater Attached to Substrates for Satellite Applications

다국어 초록 (Multilingual Abstract)

This study has examined the performance and temperature change characteristics of a satellite film heater fabricated using screen printing technology using silver paste. The temperature variations in the film heater attached to CFRP and Al 6061 substrates were modeled numerically in an FM (Flight Model) environment incorporating radiation heat transfers in a vacuum state under various sink temperatures. The results demonstrate that the constrained distance between heaters increases non-linearly with the sink temperature. The required power density to reach the maximum allowable temperature diminishes with the sink temperature. The required power density is higher than the ESCC standard of 0.54 W/cm², which is assessed in an EM (engineering model) environment without substrate.
