Passive Thermal 40
Passive thermal control and thermal protection aims to maintain vehicle and component temperatures within acceptable limits using passive means. Thermal control is a broad discipline including internal and external systems, component and integrated thermal model development and analysis and correlation, attitude timeline analysis, and purge, vent, and drain analysis for vehicle cavities and compartments, thermal-vacuum testing. Thermal protection focuses on reusable high temperature thermal protection insulations such as tiles and high temperature blankets, the thermal aspects of hot structure, seals and barriers, ablative materials, thermo-mechanical analysis for induced stress, and arc jet and radiant heat testing.
