Abstract: A supersonic fan nozzle for abrasive blast removal of coatings particularly for use with plastic abrasive media, provides much greater media particle velocity, a more uniform velocity profile, and a more uniform media particle distribution than prior art nozzles. The new nozzle has a constant height throat area about 1 inch long, about 1.57 inches wide, and about 0.125 inche high. The throat opens into a constant height diverging slot which diverges at about a 6.5 degree half-angle for about 9.5 inches to a final exit width of about 3.75 inches. A nozzle-to-hose coupling connects at one end to a conventionally sized blasting hose and at the other by a rectangular opening to the throat. Used with light plastic media entrained in an airflow stream at operating pressures of 15 to 80 psig, the nozzle has successfully removed coatings from a variety of delicate underlying substrates with little or no observable damage to the substrates.

Abstract: A gas turbine engine combustor cooling system for imperforate non-metallic combustor liners has a wall positioned adjacent to the liners forming therewith a cavity. The wall has a plurality of inlets for admitting cooling air into the cavity and a plurality of outlets for exhausting the cooling air into a separate passageway after it impinges the liners. The exhausted cooling air is transferred upstream of the liner where it is combined with fuel for burning rather than discharged downstream as cooling film.

Abstract: An improved multiple-layered omnidirectional flexible joint disposed to flexibly connect between a convex spherical ball surface associated with a rocket motor nozzle and a concave spherical cup surface associated with a rocket motor case, the space between curved mounting surfaces being filled by overlapping spherically concentric layers constructed in an alternating manner of relatively rigid and relatively resilient materials interleaved and bonded to one another. The rigid layers are made of glass-fiber-reinforced epoxy-resin composite material, and extend outward beyond the edges of the resilient layers, so as to protrude toward the hot environment within the rocket motor case. The protruding edges of the glass-epoxy composite material layers tend to melt together, and thereafter protect the resilient layers from direct exposure to the intense thermal environment within the rocket motor case.

Abstract: An unsupported, flexible, quasi-linear phased-array antenna within a space-based radar system which is tethered to a host satellite in free space. The antenna is formed by a plurality of antenna elements which are connected serially along a common axis. The antenna points in an Earth-pointing direction via gravity-gradient forces acting thereon. The phased-array antenna is capable of radiating a narrow electromagnetic beam in the end-fire direction along the array either in a spot or conical beam for detecting, identifying and tracking moving targets on or near the Earth's surface. According to one aspect of the invention, the phased-array antenna forms an elongated conductor which moves through a magnetic field in space for generating electrical power.
