Overview on the Development Research of Vortex Lift Waverider

Abstract

The waverider has good aerodynamic performance in hypersonic flight,however its performance is difficult to maintain when it deviates from the design state. In order to maintain good aerodynamic performance in both low and hypersonic velocity,related researchers took the advantages of the planform-controllable waverider and put forward the“vortex lift”waverider. In this paper,the three types of vortex lift waveriders design method,namely the fixed leading edge profile method based on the osculating cone theory,the shock generating body method based on the shock-fitting method,and the projection method based on the given shock surface are summarized.The relevant research on the aerodynamic characteristics of the vortex lift waverider in the wide speed range is also reviewed,and some suggestions are put forward to the following research of vortex lift waveriders.
