Abstract:

Drag and heat reductions are two core issues in the design of high-speed flight vehicles. Drag reduction can enhance the lift-drag ratio of vehicles and decrease the fuel consumption, while heat reduction can reduce the weight of thermal protection system and promote the effective load of flight vehicles. Drag and heat reductions are the key technologies to improve the fine design and enhance the flight performance. This paper mainly reviews the research status of flow control technology for drag and heat reductions of shock wave and boundary layer, from the perspective of the engineering requirements for drag and heat reductions of high-speed flight vehicles. This paper also points out the existing problems in engineering application and the direction that should be paid close attention to in the future, to realize the engineering application of active flow control of flight vehicles and improve the flight performance.

Key words: flow control, drag reduction, heat reduction, shock wave, boundary layer
