A flow control system is used to control fluid flow at the boundary layer an object or body about or within which the fluid flows relative to the body. The flow control system includes an actuated membrane that is displaced in a direction substantially tangential to the actuated membrane, thereby causing a disturbance or modified shear stress distribution in the boundary layer fluid flow.

Method and system for regulating pressure and optimizing fluid flow about a fuselage similar body

The present invention features a fluid flow regulator that functions to significantly influence fluid flow across the surface of a fuselage or similar structure as part of a moving or stationary body, as well as to significantly effect the performance of the body subjected to the fluid. The fluid flow regulator comprises a pressure recovery drop that induces a sudden drop in pressure at an optimal pressure recovery point on said surface, such that a sub-atmospheric barrier is created that serves as a cushion between the molecules in the fluid and the molecules at the body's surface. More specifically, the present invention fluid flow regulator functions to significantly regulate the pressure gradients that exist along the surface of a body subject to fluid flow. Regulation of pressure gradients is accomplished by selectively reducing the pressure drag at various locations along the surface, as well as the pressure drag induced forward and aft of the body, via the pressure recovery drop. Reducing the pressure drag in turn increases pressure recovery or pressure recovery potential, which pressure recovery subsequently lowers the friction drag along the surface. By reducing or lowering friction drag, the potential for fluid separation is decreased, or in other words, attachment potential of the fluid is significantly increased. All of these effects may be appropriately and collectively phrased and referred to as optimization of fluid flow, wherein the fluid flow, its properties and characteristics (e.g., separation, boundary layer), and relationship to the body are each optimized.

Transparent pane with radar-reflecting properties

The panes (1) of a naval vessel or military vehicle are often coated with a radar-reflecting layer (20) for reduction of the radar signature of the vessel/vehicle. At the same time this layer increases an enemy’s possibility of recognising the vessel in passive IR reconnaissance since the layer increases the reflectance also for IR radiation to a considerable extent. As a result, the intensity of IR radiation that an enemy receives from the panes is much lower than that from the rest of the vessel, which with signal processing can be used to increase the possibility of recognising the vessel. According to the invention, it is suggested that the panes (1) on the outer face (8) also have a second layer (21, 22) to increase emittance especially within the IR range 2-20 μm which is normally used for reconnaissance and the like. This second layer (21, 22) comprises especially two coatings, one of which is active in the IR range 3-5 μm and the second in the IR range 7-14 μm. The first coating (21) is suggested to comprise tin dioxide and the second coating (22) oxidised silicon nitride.

(3) in order to change an acoustic noise spectrum of the ship. The ship's operation team can thus selectively determine a ship's noise spectrum adapted to the requirements and conditions present at a given time to operate the ship.

Aerodynamic tip protuberances for tip vortex intensity reduction

A vortex generator includes a multiple of vorticity generating protuberances that produce small-scale vortices that are entrained within a primary tip vortex. The small­scale vortices causes the primary tip vortex to diffuse and dissipate at a rate greater than what normally occurs, thereby reducing the intensity of the primary tip vortex.

Hull thermal management system

A system for controlling a thermal signature of a boat is disclosed. The system includes a fluid compartment adjacent to an external wall of the boat. The fluid compartment is disposed between a heat source in a hull cavity of the boat and the external wall of the boat such that heat energy released from the heat source is transferred to a fluid in the fluid compartment. A fluid mover moves a first volume of the fluid out of the fluid compartment and replaces at least a portion of the first volume with a second volume of fluid, wherein the second volume of fluid has a different temperature than the first volume of fluid before entering the fluid compartment.
