Abstract:
Methods and apparatus for an actuator system according to various aspects of the present invention include a housing; a sleeve having a deformable portion; and a mover for applying force to the sleeve. The sleeve, which is sealed to the housing, is configured to reside and move within the housing. The mover applies a force against a portion of the sleeve, causing the deformable portion to deform and move.
Abstract:
A deployable raceway harness assembly for use with a multi-stage rocket includes a first cable bundle configured to extend across a second stage of a multi-stage rocket from a guidance unit to a first stage of the rocket. The deployable raceway harness assembly includes a deployable raceway cover configured for detachable coupling with the multi-stage rocket. The deployable raceway cover extends over at least the first cable bundle and a second cable bundle. The first cable bundle is fastened to the deployable raceway cover. The second cable bundle is configured to extend from the guidance unit to the second stage and is shorter than the first cable bundle. An in-flight deployment mechanism is configured to detach the deployable raceway cover and the first cable bundle extending across the second stage from the multi-stage rocket in-flight leaving the second cable bundle extending to the second stage in place.
Abstract:
A gripping jaw assembly for a pull tool for setting pull type fasteners of a type which include a pin and collar and/or sleeve with the pin having a pull portion adapted to be gripped by a plurality of jaws in the jaw assembly with the jaws having a plurality of gripping teeth and with the jaws being movable in separate guide tracks and also supported in a manner whereby the jaws and their gripping teeth are maintained axially and radially in phase with each other and with the pull portion of the pin and with the jaw teeth of the separate jaws being maintained in phase with each other when gripping the pull portion of the pin.
Abstract:
Projectiles that include a propulsion system and a launch motor which are located on opposing sides of a payload and a method of directing a projectile toward a target are generally described herein. Placing the propulsion system and the launch motor on opposing sides of the payload may provide many potential advantages when designing the projectile. These design advantages may make it easier to create a projectile that includes more propellant and/or payload while still permitting the projectile to be stored within existing containers having a fixed size.
Abstract:
A gripping washer includes a washer body having first and second rigid support surfaces. A fastener hole extends between the first and second rigid support surfaces. An inner washer perimeter extends around the fastener hole. One or more elastomeric gripping tabs are coupled with the inner washer perimeter. The one or more elastomeric gripping tabs extend inwardly into the fastener hole from the inner washer perimeter. The elastomeric gripping tabs are pliable relative to the first and second rigid support surfaces of the washer body and deform and grip the washer with a fastener passed through the fastener hole. By gripping a fastener with the elastomeric gripping tabs the gripping washer is anchored to the fastener and substantially prevents decoupling of the gripping washer from the fastener prior to installation (e.g., fastening with a work piece). Gripping of the fastener with the gripping washer thereby minimizes foreign object debris.
Abstract:
A toroid pressure vessel includes a toroid body having an inner shell and an outer shell. The toroid body includes a toroid outer perimeter. The outer shell extends along the toroid outer perimeter. A planar exterior face extends along at least a portion of the outer shell and the toroid outer perimeter. A support belt circumscribes the toroid outer perimeter and is coupled along the planar exterior face. The support belt braces and supports the pressure vessel along the toroid outer perimeter against bulging force (and hoop stress) generated by pressurized fluids within the vessel. The support belt facilitates the use of thinner pressure vessel shells and thereby decreases the weight of the pressure vessel while providing a support to the outer shell that substantially prevents deformation of the planar exterior face.
Abstract:
Some embodiments pertain to a projectile and method that includes a flight vehicle and a propulsion system attached to the flight vehicle. The propulsion system includes a plurality of motors that propel the projectile. A guidance system is connected to the propulsion system. The guidance system ignites an appropriate number of the motors to adjust the speed of the projectile based on the location of the projectile relative to a desired destination for the flight vehicle. In some embodiments, the flight vehicle is a kinetic warhead. The projectile may be an interceptor that includes a first propulsion stage, a second propulsion stage and a third propulsion stage that includes the third propulsion system. The number of booster motors that will be ignited by the guidance system depends on the speed that the projectile needs to be adjusted to in order to maneuver the projectile to a desired location.
Abstract:
A swage type fastener including a swageable collar member having a pintail member secured thereto to define a pintailed collar; the pintailed collar is operable to be secured to a stud or pin member by an installation tool which applies a relative axial force between the pintail member and collar member to cause a swage anvil to swage the collar member into a locking groove portion on the pintail member and then to sever the pintailed member from the installed collar member; the stud or pin member can have a gripping groove construction at its free end to grip the collar member at initial swage and relatively low swage loads and to resist the installation tool pulling the collar member into the swage anvil instead of swaging it onto the stud or pin member under the subsequently high swage loads.
