To determine the capability of a morphing hypersonic waverider, this paper develops an optimal morphing control scheme to quantify the impact that the representative morphing error has on aerodynamic performance. The morphing waverider concept could improve thermal loading, vehicle acceleration, local and global load factors, fuel consumption, and total energy dissipation. The key design limitation of conventional waveriders is that the optimal geometry is highly dependent on the Mach number, and deviations from the design point significantly degrade performance. The Naval Research Laboratory has developed a family of morphing waveriders with a constant leading edge and a top surface with a morphing lower stream surface to enable ondesign performance across a wide Mach number range. To evaluate the morphing waverider concept, a Mach 10 waverider is designed to enable shock attachment from Mach 10 to 5. A Q-DEIM-algorithm sensitivity analysis identifies the optimal control points set (actuator locations). This paper shows that the ideal morphing waverider significantly improves performance and a two-control-point or six-control-point system provides 90 and 97% of the ideal control system performance improvements. This work demonstrates a methodology to actuate the waverider lower stream surface to enable optimum aerodynamic performance across a range of Mach numbers.
