The leading edges of wings, nose assemblies, tails, fins, struts, and other components of aircraft, atmospheric entry vehicles and missiles in which the leading edge is blunted and the flight Mach number is supersonic, are provided with passive airflow channel, resulting in significantly reduced wave drag and total drag, significantly increased lift-to-drag ratio, and reduced sonic boom.

1. A body component for reducing drag during at least supersonic motion of the body component in a flow, the motion being in a direction of travel, said body component comprising a leading edge, a trailing edge generally opposite said leading edge, an upper surface extending between said leading edge and said trailing edge, and a lower surface extending between said leading edge and said trailing edge and separated a distance from said upper surface, thereby defining an interior volume within said body component, said body component further comprising a channel extending through said interior volume between an inlet opening at said leading edge and a single outlet opening in said body component below said upper surface, wherein said channel has a cross-sectional area whereby at the at least supersonic motion of the body component, a detached normal shock wave develops in front of said leading edge so the flow enters said channel with subsonic relative motion, creating a subsonic section at the inlet opening of said channel.
