    摘要： A seal for preventing extremely hot gases from passing between a movable engine ramp and an engine splitter wall in a hypersonic aircraft. The seal moves with the engine ramp, in a direction parallel to the surface of the splitter wall. The seal includes a first flange which makes sliding contact with the outer engine ramp surface and is attached to a flexible sealing portion that fills the gap between the ramp and wall. The sealing portion maintains sliding contact with the wall as the gap changes dimension due to variations in the ramp's temperature. The attachment region can be a concave surface to radiate the seal's heat. In a second embodiment, the seal includes a second flange through which the seal is attached to the cooler side of the engine ramp.

    摘要： The invention provides a thermal insulation blanket suitable for removable mounting on a structure such as the exterior of a reusable launch vehicle. In one embodiment, the invention include a batting layer with a rigid screen embedded within it. A cover layer is secured over the batting, and a plurality of fasteners are held by the screen in a position where they extend out from the blanket to be mounted on the exterior of the space craft. The blanket can include two layers of batting with the screen disposed therebetween. The structure would have corresponding mating fasteners on its exterior to which those extending out from the blanket cover would be joined for a secure mount. The blanket can be formed of a first and a second batting layer with the screen positioned therebetween. In a preferred embodiment, a cover would be positioned over the batting layers, and the blanket would be quilted to hold the layers and cover in close proximity. In an embodiment suitable for launch vehicle use, the materials used for the batting, cover and quilting thread would be suitable ceramic fiber materials capable of withstanding reentry heating. The screen can be fabricated of titanium, stainless steel, or other material capable of withstanding reentry temperatures. The fasteners could be any of a variety of commercially available fasteners.

    摘要： A passive thermal protection system that overcomes the disadvantages of the polyurethane "water wall" includes a fiberformed ceramic insulation, a plurality of electrodes embedded in the insulation to define a wick panel, and a gelled ceramic sol in the wick panel. The system can be prepared by introducing the sol into the wick panel with its subsequent gelling by applying a direct current across the electrodes. Cooling water is held in the gelled sol to provide passive cooling, yet the system easily achieves even distribution of the water (even when subject to accelerations) without the use of pre-gelled or viscous reagents.
