Latest Patents

One of Uhlman's latest patents is titled "Adaptive material actuators for Coanda effect circulation control slots." This invention provides a system and method for introducing tangential control fluid flows along the surface of an aerodynamic member. The fluid flows are directed toward a Coanda surface located at the trailing edge of the aerodynamic member. The design includes at least two injection slots on opposite sides of the aerodynamic member, which produce opposing forces. The control of fluid flow from each slot determines the net effect of these opposing forces. Smart material actuators are utilized to control the flow of fluid by varying the size of each slot.

Another significant patent is the "Device for stabilizing re-entrant cavity flows past high-speed underwater vehicles." This stabilizing device is designed for supercavitating vehicles and isolates re-entrant jet flows of liquid from its cavity. The device features a receiving means positioned on the supercavitating vehicle where the re-entrant jet flow impinges. An exit means is connected to the receiving means to carry the received re-entrant jet flow out of interference with the cavity. This innovation stabilizes the cavity, improves controllability and maneuverability of supercavitating vehicles, and reduces self-generated noise, enhancing the operation of acoustical sensors incorporated in the vehicle.
