摘要： A compact diffuser for recovering pressure from a supersonic flow with boundary layers. Sharp splicer plates near the wails form boundary layer scoops and separate the flow into an inner coreflow chapel and outer chambers containing small supersonic ejector nobles. The coreflow without boundary layers undergoes a single near-normal shock to recover pressure. The boundary layers are pumped to the recovery pressure in the outer ejector chambers. The subsonic part of the boundary layer flow to the outer chambers can be choked against boundary layer scoop inlet corners to isolate the upstream flow. The leading edge angle of the splicers may be selected to help induce coreflow shocking.

摘要： Methods and apparatus are provided to control flow separation of an ambient flow along a surface and about a turret, such as by reducing flow separation aft of the turret. By reducing flow separation, the resulting turbulence may be similarly reduced such that the performance of a system, such as a laser system, housed by the turret may be improved. To reduce flow separation, a motive flow may be provided by ejector nozzles that open through the surface and are positioned proximate to and aft of the turret relative to the ambient flow. The motive flow has a greater velocity than the ambient flow to thereby create a region aft of the turret of reduced pressure relative to an ambient pressure. Within this region of reduced pressure aft of the turret, a portion of the ambient flow mixes with the motive flow, thereby reducing or eliminating flow separation.

摘要： A system and methods for broad area visual obscuration around a platform. In one embodiment the system comprises a source of visible light, shaping optics and projecting optics. The system projects a light beam onto an illumination area in a sweeping pattern to repetitively illuminate all portions of the illumination area, such that a stationary observer within the illumination area receives repeating pulses of the light at a power, intensity, frequency and duration sufficient to visually impair the observer so as to substantially prevent the observer from discerning the platform between pulses. The light pulses are capable of temporarily blinding human eyes but incapable of causing permanent vision loss.

摘要： An apparatus and method for vaporizing liquid are provided which employ a plurality of rods disposed within a storage vessel that serve as the heat transfer element. While the plurality of rods are generally submerged by the liquid fuel to facilitate heat transfer and vaporization of the liquid fuel, the rods may be packed closely together such that the liquid inventory required to maintain the rods in a submerged state is substantially less than required by conventional fuel supply systems, thereby permitting the weight of a fuel supply system that incorporates the apparatus and method to be reduced while still permitting effective vaporization of the fuel.
