摘要： Pulsed detonation engines (PDEs), or various components thereof, such as the detonation chamber and/or nozzle, can be economically constructed from materials having low thermal stability, such as plastics, composites, and light metals. During operation, the intermittent injection and detonation of reactants produces a motive force (e.g., thrust) over relatively short intervals useful in orbit control and the like. The relatively short intervals of operation prevent temperatures of the PDE components from reaching temperatures that would result in their dimensional failure.

摘要： A thrust chamber assembly for liquid fueled rocket engines and the method of making it wherein a two-piece mandrel having the configuration of an assembly having a combustion chamber portion connected to a nozzle portion through a throat portion is wrapped with a silica tape saturated with a phenolic resin, the tape extending along the mandrel and covering the combustion chamber portion of the mandrel to the throat portion. The width of the tape is positioned at an angle of 30 to 50° to the axis of the mandrel such that one edge of the tape contacts the mandrel while the other edge is spaced from the mandrel. The phenolic in the tape is cured and the end of the wrap is machined to provide a frustoconical surface extending at an angle of 15 to 30° with respect to the axis of the mandrel for starting a second wrap on the mandrel to cover the throat portion. The remainder of the mandrel is wrapped with a third silica tape having its width positioned at a angle of 5 to 20° from the axis of the mandrel. The resin in the third tape is cured and the assembly is machined to provide a smooth outer surface. The entire assembly is then wrapped with a tow of graphite fibers wetted with an epoxy resin and, after the epoxy resin is cured, the graphite is machined to final dimensions.

摘要： A stiffened composite is provided exhibiting multi-directional reinforcement with continuous long fibers. The composite has a substrate and serpentine stiffeners adhered thereto. The stiffeners merge toward, join with and diverge from adjacent stiffeners to provide a stiffener matrix on the substrate. The serpentine stiffener permit the matrix to exhibit multi-directional reinforcement with the continuous long fibers within the serpentine ribs. The composite structures are useful as aircraft bypass ducts, and as other composite products.

摘要： A combustor liner includes an inner layer for facing combustion gases, and an opposite outer layer for facing a cooling fluid. The outer layer has a greater coefficient of thermal conductivity than the inner layer for reducing temperature gradients in the liner. In a preferred embodiment, the outer layer significantly reduces temperature gradients in the liner which are caused by the varying cooling ability of impingement cooling air jets for more uniformly cooling the combustor liner and reducing the maximum temperature thereof.

摘要： A solid fuel rocket engine comprises a casing which defines a combustion chamber with a solid propellant charge in the combustion chamber and an insulating layer of a water containing alkali silicate and fibers disposed between the casing and the charge. The layer is a type which will froth at a predetermined temperature which occurs during burn off of the propellant charge so that it increases in its thickness dimension in the area of the hot gases which develop and provides an adequate insulation. A method of producing the layer comprises heating the alkali silicate layer to a temperature in which it becomes plastic and sheathing the propellant charge with the plastic layer. Thereafter the sheath charge is inserted into the combustion chamber casing leaving an annular gap between this layer and combustion chamber casing. Thereafter heat is applied to the vicinity of the chamber to cause the layer to froth and expand to close the annular gap. It is advantageous to include a lining of a plastic alkali layer in addition to the layer which sheaths the propellant charge between it and the casing. In addition, it is sometimes advantageous to add a plastic foam material in the gap between the sheath, the cover charge and the casing.
