Title
(EN) METHOD AND APPARATUS FOR PROVIDING HIGH CONTROL AUTHORITY ATMOSPHERIC PLASMA
(FR) PROCÉDÉ ET APPAREIL PERMETTANT DE FOURNIR UN PLASMA ATMOSPHÉRIQUE DE HAUTE AUTORITÉ DE CONTRÔLE
Abstract
(EN) Embodiments of the invention relate to a method and apparatus for providing high thrust density plasma, and/or high control authority plasma. In specific embodiments, such high thrust density, and/or high control authority, plasma can be at or near atmospheric pressure. Embodiments pertain to a method and apparatus that use electron confinement via one or more magnetic fields, and/or one or more electric fields, in a manner to improve the ionization due to surface plasma actuators. Specific embodiments can improve ionization by several orders of magnitude. This improved ionization can result in a high electric field inside the sheath for the same applied voltage and can result in very high thrust.
(FR) La présente invention se rapporte, dans des modes de réalisation, à un procédé et à un appareil permettant de fournir un plasma de densité de poussée élevée et/ou un plasma de haute autorité de contrôle. Selon des modes de réalisation spécifiques, un tel plasma de densité de poussée élevée et/ou de haute autorité de contrôle peut être à une pression atmosphérique ou proche de cette dernière. Des modes de réalisation se rapportent à un procédé et à un appareil qui utilisent le confinement des électrons par l'intermédiaire d'un ou plusieurs champs magnétiques et/ou d'un ou plusieurs champs électriques de manière à améliorer l'ionisation grâce à des actionneurs de plasma de surface. Des modes de réalisation spécifiques peuvent améliorer l'ionisation de plusieurs ordres de grandeur. Cette ionisation améliorée peut entraîner un champ électrique important à l'intérieur de la gaine pour la même tension appliquée et peut entraîner une poussée très importante.
