Abstract: Micro-electro-mechanical (MEM) translational tabs (26) are introduced for enhancing and controlling aerodynamic loading of lifting surfaces. These microtabs (26) are mounted at or near the trailing edge (24) of lifting surfaces, deploy approximately normal to the surface, and have a maximum deployment height on the order of the boundary layer thickness. Deployment of this type of device effectively changes the camber, thereby affecting the lift generated by the surface. The effect of these microtabs (26) on lift is as powerful as conventional control surfaces such as ailerons. Application of this simple yet innovative lift enhancement and control device will permit the elimination of some of the bulky conventional high-lift and control systems and result in an overall reduction in system weight, complexity and cost.
