  • Patent number: 3981144
    Abstract: A diffuser having a dual-stage configuration with the diffusing element of the first stage aligned perpendicularly to the second stage. The diffuser vanes of the first stage are inclined at an angle to the direction of flow so that the flow field between the first stage and the second stage changes from the conditions before diffuser starting to the conditions after diffuser starting to produce an effect similar to the change in flow cross section of a variable throat area diffuser. The second stage of the diffuser has its wall configured similar to the contour of a two dimensional ramjet inlet diffuser.

  • Patent number: 3969907
    Abstract: The cold cylinder assembly for a two stage Vuilleumier cycle cryogenic refrigerator having an outer cylinder forming a first chamber of a large diameter and a second chamber of a smaller diameter with a cold displacer within the cylinder. The cold displacer includes a first stage regenerator and a second stage regenerator. Gas from the crankcase passes through channels in the rider ring and then through ports to an annular passage within the cold displacer and then to the first stage regenerator. Gas from the first stage regenerator divides into two parts with one part passing to the second stage regenerator and then through passages to ports to impinge on an end member for the second stage heat load. The other part flows through passages to ports to impinge upon an end wall for the first stage heat load.

  • Patent number: 3970006
    Abstract: A missile nose cone removable protective cover having a rigid outer shell of cross-linked polyethylene with a semirigid backing of polyurethane foam. A shaped linear charge is positioned in a serpentine pattern between the rigid outer shell and the foam backing. The shaped linear charge is detonated by means of a detonator in an epoxy junction box in the forward end of the nose cover.

  • Patent number: 3946481
    Abstract: An apparatus for removing taper lock bolts from aircraft wings having a lever arm and a bolt which acts as a fulcrum for the lever. The fulcrum bolt is attached to the aircraft wing by means of a taper lock bolt which is adjacent to the taper lock bolt to be removed. The lever arm is operated by a pull rod which passes through a hole in the wing. A commercially available porta power tool provides an upward force on the pull rod to turn the lever arm around the fulcrum bolt to apply a downward force on the taper lock bolt to be removed.

  • Patent number: 3942320
    Abstract: A solid boron fuel burning ramjet engine having a cylindrical primary burner located within a ramjet combustion chamber. A portion of the air bypasses the primary burner to provide secondary burning at the outlet of the primary burner. Solid boron fuel pellets are ground to powder in a wire brush fuel mill with the fuel then being carried to the primary burner by air which is passed through the fuel mill.

  • Patent number: 3941335
    Abstract: An ejector wing, for an aircraft, having inlet and diffuser doors which move from an open take-off configuration to a closed forward flight configuration and having hypermixing nozzles and root nozzles for supplying primary air into a plurality of channels in the wing structure. Apparatus is provided for controlling the air flow from the root nozzles in the boundary layer in the channels. A plurality of sensing ports are provided in the channels upstream of the root nozzles. The differential pressures at the sensing ports are used to divide the flow to the root nozzles on opposite sides of the channels.

  • Patent number: 3938889
    Abstract: A method and apparatus for measuring the linear thermal expansion of a polymeric material wherein a sample with a wedge surface is mounted on a graphite block within a temperature controlled chamber. The incident and reflected beam of a laser lie in a plane perpendicular to the plane of the base of the sample and make equal angles with a line perpendicular to the plane of the base of the sample. A holographic plate is exposed by the object beam from the sample and a reference beam. The temperature is gradually increased from 0.9.degree. to 4.degree. F. between a first exposure and a second exposure. A thermocouple and indicator are used to indicate the temperature of the sample at the time of each exposure of the holographic plate. The holographic plate is then developed and replaced in the plate holder for reconstruction of the images and the fringe pattern, which indicates the expansion of the sample.
