Abstract:

Hypersonic airbreathing vehicles are characterized by highly-integrated airframe and propulsion system. Computational Fluid Dynamics CFD tools have been used extensively in the design and analysis phrase of hypersonic vehicles. In this paper, an engineering method and a finite volume method based on the center of grid are developed tor preliminary research of interested integrative hypersonic vehicles with waverider configurations cone-shaped or canard structure. Some longitudinal aerodynamic performance increments are obtained under conditions of shut-down engine or working engine. For the vehicle with canard structure, in order to study the lateral-directional stability characteristics, we also consider the influence of yaw angle on the flow field of fore-body.
