CA 2625520

An aircraft includes a surface over which an airflow passes. A plasma actuator (1) is configured to generate a plasma above the surface, the plasma coupling a directed momentum into the air surrounding the surface to reduce separation of the airflow from the surface. A method of reducing separation of an airflow from a surface of an aircraft includes generating a plasma in air surrounding the surface at a position where the airflow would separate from the surface in the absence of the plasma.

Sachant qu'un aéronef comprend une surface sur laquelle passe un flux d'air, on décrit un activateur de plasma produisant un plasma au-dessus d'une surface, ce plasma assurant le couplage d'un élan orienté dans l'air entourant la surface pour réduire une séparation du flux d'air par rapport à la surface. On décrit aussi un procédé de réduction de ladite séparation par rapport à une surface d'aéronef, qui consiste à produire un plasma dans l'air entourant la surface en une position dans laquelle le flux d'air se séparerait de la surface en l'absence de plasma.
