    摘要: A multi-pulse rocket is equipped with a thermally insulating barrier that serves as a rupture disk or a movable plug or plate separating staged propellant grains. When a rupture disk it used, the disk can be equipped with a pyrotechnic actuator to weaken the disk upon command, enabling the propellant grain on the fore side of the disk to burst the disk at a relatively low pressure when ignition of the propeiiant grain is needed for additional thrust. Rupturing of the disk can also be controlled by attitude maneuvering ports on the tore side of the barrier whose open or closed conditions are controlled by independently operable closures. When a movable plug is used, the plug is movable between a closed position separating rocket chamber into subchambers isolating the propellant grains from each other and an open position allowing the flow of combustion gas between the two subchambers.

    摘要: A pilot for a scramjet provides a flame front 28 whose arrival at the wall of the scramjet combustor 18 is delayed thereby reducing combustor 18 heat load By combining ιn-stream injection of fuel 19 with an interior pilot and a lean (fuel-poor) outer annulus, the bulk of combustion is confined to the scramjet combustor 18 center This concept, referred to as 'core-burning,' further reduces combustor 18 heat load One such pilot is for a two dimensional scramjet 40 effective to propel a vehicle This pilot includes a plurality of spaced apart struts 44 separated by ducts and a strut pilot 43 contained within each strut 44 A second such pilot is for an axisymmetric scramjet engine has, in sequence and in fluid communication, an air intake 16, an open bore scramjet isolator 50 and a scramjet combustor 18.

    摘要: Thrust augmentation in a rocket nozzle is achieved by incorporating injectors for the introduction of unburnt fuel and oxidizer into a nozzle to combust in the nozzle and thereby supplement the primary thrust that is supplied by fuel and oxidizer that are combusted prior to entry into the nozzle. These secondary injectors are incorporated into the design of expansion-deflection nozzles and plug nozzles. In expansion-deflection nozzles, the injectors are either in the flow deflector itself or in the wall of the divergent section of the nozzle. In plug nozzles, the injectors are either in a shell of the nozzle surrounding the forward end of the centerbody or in the centerbody itself.

    摘要: A fire extinguisher includes a tank and a gas generator breech connected to the tank. The gas generator breech is provided with a hermetically sealed gas generator cartridge. The hermetically sealed gas generator cartridge avoids the need to have a release poppet or burst shims on the gas generator breech. The enclosed space that contains combustion gas pressure is provided by the gas generator cartridge itself and not the gas generator breech. The gas generator cartridge is made from a container that can be the precursor to a beverage can used for carbonated beverages. The beverage can may corne in a thickness and material of construction that makes it a suitable, cost-effective container for the gas generator cartridge. However, other containers besides precursors of beverage cans can be used.

    摘要: A relatively inexpensive system and method for regulating the temperature of a cryogenic liquid in a storage vessel (2), such as vehicle refueling station, comprises inner and outer walls (6, 8) defining a inner chamber (12) for housing the cryogenic liquid. To provide a variable thermal resistance around the inner chamber, a thermal control fluid is disposed within an insulation space (10) between the inner and outer walls. A fluid conduit (30) has an inlet and outlet in fluid communication with the chamber and a heat exchanger coil (36) disposed within the insulation space. A control valve (38) allows the cryogenic liquid to flow through the fluid conduit so that the cryogenic liquid is in heat exchange relationship with the thermal control gas as the liquid passes through the coil (i.e., the cryogenic liquid cools and condenses the thermal control gas to reduce the control gas pressure). The pressure of the control gas within the insulation space can be modulated to thereby control the heat flow into the inner chamber by controlling the flow rate of the cryogenic liquid through the fluid conduit.

    摘要: An aft closure assembly manufactured from two separate and distinct pieces made from different materials is provided for a rocket motor case. The aft closure assembly includes at least a retaining ring piece made from a first material similar to or having a coefficient of thermal expansion similar to that of the motor case. The aft closure assembly includes a blast tube and closure piece that can be manufactured from a second material that does not need to be similar to nor have a coefficient of thermal expansion similar to the motor case and retaining ring piece. This is possible because the blast tube and closure piece includes a face seal that seals against a face of the retaining ring.
