Boundary layer influencing method for aircraft wings

摘要

A permanent wave front (2) moving in the direction of flow (3), is generated on the outer surface (1) of the wing subjected to the flow. The waves in the front extend almost orthogonal to the movement direction of the front. The flow particles coming close to the surface of the wing are moved by the wave front in the direction of the wave course. The wave front is generated as a migratory flex wave in the outer active surface of the wing, by two superimposed electrical oscillations with a phase displacement of approx. 90 deg .
