Abstract

The longitudinal static stability of waverider is closely related to the streamline feature of the lower surface. The relationship between the design parameters and the "concave" and "convex" characteristic of the streamlines is studied. The results show that due to the effect of the shock compression and wall expansion, the streamlines behind the shock plane compose of two parts, the "inner concave" part and the "outer convex" one. The design parameters c, n, Ma, L and the position of the leading edge point will affect the "concave" and "convex" characteristic and the longitudinal static stability of the power-law waverider evidently. When the parameter c is larger, the parameter n is smaller, the parameter Ma is greater, and the parameter L is longer, or the leading edge point is closer to the head of the basic flow field, the "inner concave" part of the streamline will be shorter and the longitudinal static stability will be better. In addition, the shape of the leading edge will not influence the longitudinal static stability of the power-law waverider if other design parameters are determined.
