A jet actuator positioned within a hollow space in an aerodynamic structure for controlling the flow over an aerodynamic surface thereof includes a movable member linearly displaced by a voice coil mechanism and a flexible diaphragm defining a compression chamber open to the exterior of the aerodynamic surface through an orifice. Reciprocal displacement of the movable member changes the shape of the flexible diaphragm to alternately expel fluid (e.g., air) from and pull fluid into the compression chamber through the orifice. The movable member includes a...
1. A jet actuator for control of an aerodynamic structure, comprising:an aerodynamic structure having an aerodynamic surface and a hollow space adjacent the surface; an orifice opening through the aerodynamic surface adjacent to the hollow space; a substantially rigid movable member sized to fit within the hollow space, the movable member having a pair of pistons connected by an elongated cross element defining an axis, the movable member being substantially symmetric in terms of its mass about a plane extending perpendicularly through the mid-point of t...
