Method and aerodynamic body with device for reducing the drag of a limited supersonic flow region

摘要

The method is for the reducing of a wave drag connected to a limited supersonic flow region via a surface of an aerofoil (1). Spoilers for the creating of weak compression shocks (9) are provided on the surface of the aerofoil in the flow direction (6) in front of a strong compression shock (7) terminating the supersonic region. Groups each with a number of small spoilers are arranged on the surface (2) of the aerofoil and are extended in the flow direction and spaced apart at right angles to the flow direction. An independent claim is included for a device for the reducing of a wave drag on an aerofoil.
