A thermal protection structure with integrated functions of bearing/heat protection/power supply

Abstract

The invention discloses a thermal protection structure with integrated functions of bearing / heat protection / power supply. The thermal protection structural unit is composed of a thermal protection unit and a gap thermal protection component; the thermal protection unit includes a load-bearing frame, a thermoelectric layer and a position-limiting socket core , the gap thermal protection component includes a heat-resistant layer, a heat-insulating layer, a structural interface layer, and a temperature-controlling layer; the thermoelectric layer includes a high-temperature thermoelectric layer and a medium-temperature thermoelectric layer; Both are connected by high temperature resistant glue. The thermal protection structure with integrated thermoelectric conversion function of the present invention introduces thermoelectric materials and temperature control materials into the design of the thermal protection structure. By rationally designing the thermal protection unit and gap thermal protection components, under the premise of satisfying the load-bearing function and thermal protection function, Using the temperature difference of the thermoelectric material layer to generate power is of great significance for reducing the weight of aircraft that work for a long time in a severe thermal environment and improving the utilization rate of the internal space of the aircraft.

Description

technical field [0001] The invention belongs to the field of overall design of aerospace vehicles and multifunctional structural material design, and relates to a thermal protection structure with integrated functions of bearing, heat protection and power supply. Background technique [0002] Hypersonic cruise vehicles need to work for a long time in a harsh geothermal environment. Traditional aircraft thermal protection system designs usually take away heat by ablation or use the properties of the material itself to resist heat, which does not meet the long-term work requirements of the aircraft. The work will inevitably increase the requirements for the power source to be carried. On the one hand, it will occupy the internal space of the aircraft, and on the other hand, it will increase the weight of the aircraft. [0003] Therefore, it is urgent to break through the original thermal protection system design ideas, from the perspective of thermal management, change "blocki...
