  • Patent number: 5259430
    Abstract: This invention provides an improved aircraft wheel rim wherein a demountable tire bead flange has an annular chamfer within the outboard end of the flange bore, and a split lockring which cooperates to maintain the flange on the wheel rim body has an outer surface chamfer which matches the flange bore chamfer, the angle of the flange bore and lockring surface chamfers being determined by the coefficient of friction of the material comprising the wheel rim assembly such that a compressive wedge-locking load force exists at the chamfer joint as may be imposed by inflation of a rim-mounted tire.

  • Patent number: 5235128
    Abstract: This invention provides provides a separable nosecap for the forward end of a homing torpedo, the nosecap and torpedo comprising a missile that is launched into the atmosphere for a ballistic trajectory to a distant underwater target. The nosecap comprises a nosecap shell having a volume of rigid cushioning foam material within its interior space defining a cavity into which is mounted a pneumatic apparatus including a flexible inflatable sleeve for forcefully disengaging the nosecap from the torpedo after the missile has entered the water environment. The inflatable sleeve engages the forward end of the torpedo and, upon inflation and axial extension, the sleeve disengages the nosecap from its mounting to the torpedo such that a homing mechanism of the torpedo may guide it to the intended target.

  • Patent number: 5099960
    Abstract: The invention provides an integral brake disk comprised of two brake disks each having a disk thickness of one-half the design required disk thickness and these two disks are clamped together in planar face-to-face orientation by fasteners to form the integral brake disk. The integral brake disk has an inboard-facing brake wear surface provided by a wear surface of a first of the combined brake disks and an outboard-facing brake wear surface provided by the second of the combined brake disks. The integral brake disk is put into braking service for a first period after which refurbishment is required. The integral brake disk is refurbished by declamping the two disks and grinding the worn wear surfaces to planar specification. The two disks are recombined at the ground planar surfaces and reclamped to form a new integral brake disk.

  • Patent number: 4995483
    Abstract: This invention provides brake clamping and declamping in response to a position feedback controlled brake actuator in which an electric torque motor drives a rotating member of a reciprocating drive mechanism to axially move another member into out of engagement with a brake pressure plate of a multi-disk brake assembly. A microprocessor controller receives electric signals indicative of (i) a pilot's command for braking, (ii) a command for brake release and antiskid braking, (iii) the position of the torque motor rotor at any instant, and (iv) the initiation of brake clamping of the multi-disk brake. The controller generates a feedback control signal to the torque motor which adjusts the motor rotor position, in revolutions, to increase or decrease brake clamping in accordance with the pilot signal and to effect brake release in accordance with an overriding antiskid signal.

  • Patent number: 4905935
    Abstract: An aircraft windshield transparency includes a base frame defining an opening into which an inboard-positioned transparency is mounted with at least one outboard-positioned transparency and an interlayer between the two transparencies. The interlayer exhibits a stronger adhesion to the outboard transparency than to the inboard transparency. The peripheries of the outboard transparency and interlayer carry a means which functions to expose a groove penetrating to the surface of the inboard transparency such that the outboard transparency and interlayer may be removed and the inboard transparency thereafter functions as the primary windshield transparency of the aircraft.

  • Patent number: 4865162
    Abstract: This invention provides a roller screw drive mechanism (60) driven by an electric torque motor (50) through a gear drive (58,58',58") associated with either the screw (64,94) or nut (62,92) member of the roller screw drive mechanism. Rotation of the gear drive (58, 58', 58") by the torque motor (50) effectively moves the other member of the roller screw drive mechanism into axial engagement with the brake pressure plate (32) for braking action in response to an electrical control signal fed to the torque motor. A plurality of torque motor driven roller screw drive mechanisms are mounted in a balanced arrangement about the axis of the wheel and brake assembly to effectively apply and release a brake pressure force on the brake pressure plate in response to an electrical control signal to the torque motors.

  • Patent number: 4788766
    Abstract: A method of fabricating a multilayer circuit board assembly capable of operating at microwave frequencies. Specifically, multilayer circuits such as complex beam forming networks and antennas having internal via holes may be fabricated in a single bonding cycle. This is accomplished by first preparing individual circuit boards (10) by pre-forming holes (18) through circuitry (14,16) etched on opposite sides of a substrate (12). The holes (18) are next selectively plated with a conductive layer (20) and then with a material (24) capable of forming a melted fusion bond and/or a solid-state fusion bond. Bonding film (56) is placed between each board-to-board interface of a multi-board assembly and the assembly of boards is subjected to a bonding cycle of heat and pressure wherein an integral unit is effected.

  • Patent number: 4788914
    Abstract: A nosepiece for the forward end of a missile that is launched into the atmosphere for a ballistic trajectory and a water entry impact comprises a frangible base and a separable nosecap, the base having multiple segments of rigid foam defining an axial bore into the base and a volume of soft cellular foam within the bore to protect the forward end of the missile. The nosecap is in seated relationship within the bore opening on the tip end of the base during airborne flight and separates therefrom to expose the axial bore opening prior to water entry impact such that upon impact the base is fractured by the force of water entering the exposed bore and thus separated from the missile.

  • Patent number: 4696376
    Abstract: A torque tube (50) having a cylindrical body (50a) is characterized by a plurality of key surfaces (50k) which extend radially from the surface (50s) and extend longitudinally from an inboard end (50i) to terminate at an outboard end (50o) in a radius (R3) which defines a transition (50t) into a radially extending rib (50r). The cylindrical body portion between adjacent keys (50k) also extends at the outboard end (50o) into a flange (50f) which is continuous about the outboard end of the tube. The combination of radially extending ribs (50r) and flange (50f) define T-sections at the outboard end (50o) which provide the strength requirements of the torque tube in its intended service application.
