摘要 文摘主要论述长时间气动加热飞行器热防护系统隔热机理的新概念,提出传统的单相固体热传导由于其隔热机制的局限性,已不能解决新型高超声速式飞行器的隔热问题,代之以气—固的辐射—传导—对流复合传热机制。多相复合传热机理可解决长时间气动加热飞行器隔热的问题。 The new concept of insulation mechanism of thermal protection system for spacecraft with long time aero-heating is presented, it is pointed out that traditional heat conduction of single phase solid can not solve the insulation problem of spacecraft with long time aero-heating because of limitation of its insulation. Therefore the new insulation mechanism is heat conduction mechanism with muhi-phase (gas-solid) and complex (radiation-conduction-convection) instead of single phase solid heat conduction.
