    • A low internal leakage, rotary vane gas compressor utilizing a housing having a generally elliptical cavity, whose outer boundary is defined by an inner stator wall. A shaft mounted rotor is disposed offset from the central axis of the cavity, with an end plate secured on each end of the housing. Each end plate has a centrally mounted hole for rotatably supporting the respective side of the rotor shaft. The housing has inlet and discharge passages, each in contact with the cavity. The rotor has a plurality of radial slots in equally spaced relation about its periphery, in each of which slots a slidable vane of minimal weight is disposed. Each vane is approximately the width of the rotor, and the outer tip of each vane is in close proximity to the inner stator wall. These vanes define a plurality of chambers which undergo significant volume changes during rotation of the rotor. The vanes thus cooperate with the inner stator wall and the end plates to compress gas entering the inlet passage, such that the gas thereafter leaving through the discharge passage is at a higher pressure. Advantageously, a seal ring of particularly hard, tough steel is mounted in each end plate, and biased into contact with the respective side of the rotor to effect an essentially zero gap therewith. Each seal ring has a tapered cross section, such that the initial footprint area is small, but with rotor wear, the small contact area desirably becomes a surface contact.

    • A solid-fuel pellet thrust and control actuation system (PT-CAS) provides command authority for maneuvering flight vehicles over subsonic and supersonic speeds and within the atmosphere and exo-atmosphere. The PT-CAS includes a chamber of solid-fuel pellets that are ignited to expel gas through a throat. The expelled gas is directed at supersonic vehicle speeds in atmosphere to a cavity between an aero control surface and the airframe to pressurize the cavity and deploy the surface or at subsonic speeds in atmosphere or any speed in exo-atmosphere allowed to flow out a through-hole in the surface where the throat and through-hole provide a virtual converging/diverging nozzle to produce a supersonic divert thrust. A pellet and control actuation system (P-CAS) without the through-hole provides command authority at supersonic speeds in atmosphere. A restrictor mechanism controls the bleed of pressurized gas from the cavity to the external environment to achieve a deployment time objective for either the PT-CAS or P-CAS.
    • 固体燃料颗粒推力和控制致动系统(PT-CAS)为在亚音速和超音速下以及大气和大气中的机动飞行器提供了指挥权力。 PT-CAS包括一个固体燃料颗粒室,它被点燃以通过喉管排出气体。 排出的气体以大气中的超音速车辆速度被引导到航空控制表面和机身之间的空腔,以对空腔加压并且将其表面或亚音速的速度在大气中或任何速度在外部气氛中流出, 喉部和通孔的表面中的孔提供虚拟的会聚/发散喷嘴以产生超音速转向推力。 没有通孔的颗粒和控制致动系统(P-CAS)在大气中以超音速速度提供命令权限。 限流器机构控制加压气体从空腔排放到外部环境,以实现PT-CAS或P-CAS的部署时间目标。
