Abstract: An aerodynamic body includes an upper surface and a lower surface. The upper surface includes a first portion of a first axisymmetric body. The lower surface is mated with the upper surface. The lower surface includes a waverider shape. The waverider shape is derived from the shockwave generated by a second axisymmetric body.

Abstract: A jet noise suppressor and an airplane are provided. The jet noise suppressor includes a nozzle with a front end, a back end, an interior surface, and an exterior surface, a plurality of struts, and a plurality of vents. Each strut includes a base and a distal end with the base of each strut coupled to the interior surface of the nozzle, and each vent corresponds to a respective strut and is formed within the interior surface of the nozzle between the front end of the nozzle and the base of the respective strut.

Abstract: Method and apparatus for controlling the aerodynamics of an aircraft using an active flow control system is disclosed herein. In one example, the active flow control system includes an airframe and a plurality of fluidic oscillators. The airframe includes an inlet configured for flight speeds ranging from subsonic to hypersonic. The plurality of fluidic oscillators is mounted about a curvature of the airframe. Each fluidic oscillator includes a body and an integral nozzle coupled to the body. The body has an inflow portion and a narrow nozzle inlet formed opposite the inflow portion. The integral nozzle is coupled to the body by the narrow nozzle inlet. The narrow nozzle inlet forms a single fluid flow path from the inflow portion to the narrow nozzle inlet.
