A vehicle includes a surface over which airflow passes. A plasma actuator is configured to generate 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 airflow from a surface of the vehicle includes generating plasma in air surrounding the surface at a position where the airflow would separate from the surface in the absence of the plasma.

Selon l'invention, un véhicule comprend une surface sur laquelle passe un flux d'air. Un activateur de plasma est configuré pour produire du plasma au-dessus de cette surface, le plasma couplant une quantité de mouvement dirigé dans l'air environnant la surface, de sorte à réduire la séparation du flux d'air de la surface. L'invention concerne également un procédé de réduction de la séparation d'un flux d'air d'une surface du véhicule. Ce procédé consiste à produire du plasma dans l'air environnant la surface, à un emplacement où le flux d'air se séparerait de la surface en l'absence de plasma.
