Title
(EN) AN ACTUATOR
(FR) ACTIONNEUR
Abstract
(EN)
The invention relates to a microvalve actuator (14) primarily for the purpose of controlling airflow to and from an aircraft wing to control aerodynamic flow thereon. The actuator (14) is manufactured using microfabrication methods and is formed from a laminate of a shim supporting layers of piezoelectric material to which voltage can be applied at rates of up to 10kHz or more to flex the laminate and open and/or close the valve orifice (20), a plurality of such actuators being operable to open and/or close orifices at a wing surface through which air jet pulses can be emitted at the wing surface.
(FR)
L'invention concerne un actionneur à microsoupape (14) servant principalement à réguler l'écoulement d'air en direction et en provenance d'une aile d'aéronef afin de réguler l'écoulement aérodynamique sur cette aile d'aéronef. L'actionneur (14) selon l'invention est produit au moyen de procédés de microfabrication, et est formé à partir d'un stratifié constitué d'une cale supportant des couches de matériau piézoélectrique, une tension pouvant être appliquée à des cadences allant jusqu'à 10 kHz ou davantage pour faire fléchir le stratifié et ouvrir et/ou fermer l'orifice de soupape (20). Une pluralité d'actionneurs selon l'invention peuvent être commandés de manière à ouvrir et/ou fermer des orifices au niveau d'une surface de l'aile, à travers lesquels des impulsions de jet d'air peuvent être émises sur la surface de l'aile.
