Abstract
To solve the problem of thermal barrier is one of the key technologies that restrict the development of hypersonic vehicles. Starting from the point that phase change materials could be used as additional heat sink, five thermal control system concepts using phase change materials are put forward based on characteristic of different vehicles. They are air cycle system, vapor cycle system, liquid loop system, open evaporation cooling system and direct phase change materials heat storage system. The key technologies for the concepts are selection of appropriate phase change materials and encapsulation design of the materials, which are discussed on the background of aeronautics and astronautics.
