Abstract
A thermal protection system includes a housing, an interior cavity, and a thermal barrier within the housing. The thermal barrier includes a compartment containing an insulating medium, and is disposed around at least a part of the interior cavity to maintain a temperature of the interior cavity within a first temperature range. A pressure relief valve arranged at least partially within the housing is in fluid communication with the insulated compartment and permits a fluid, such as air, within the compartment to pass to the environment outside of the compartment when a fluid pressure within the compartment exceeds a predetermined pressure. The compartment is sealed from the environment except for the fluid communication via the pressure relief valve. The pressure relief valve is coupled to a thermally-protected mounting within the housing that maintains a temperature of an operative portion of the pressure relief valve within a second temperature range.
