  • Patent number: 4856737
    Abstract: The present invention relates to a new and unique structure in a collapsible decelerator for aerial bodies launched from a high velocity vehicle and designed to provide a high drag stabilizer capable of withstanding release in air stream velocities from subsonic to supersonic. The decelerator preferably includes a hollow inflatable star, the outermost points of which have hooded valve openings through which regulated airflow enters and inflates the star to decelerate the body to which it is attached. The new and unique capability comprises an angular offset of each air scoop to create desired rotational speed in the selected direction.The amount of angular offset and protrusion into the air stream controls the magnitude of spin rate, the direction of angular offset controls the direction of spin.

  • Patent number: 4821984
    Abstract: A safety chamber of the telescopic type usable for an airplane includes a plurality of wall segments, granular cushioning materials and a parachute. As long as it is not in use, the wall segments are accommodated in a contracted state in the space on the ceiling of the airplace. In the event of an occurrence of emergency the wall segments are lowered one after another to constitute a chamber in which a single seat assembly is incased together with passengers sitting thereon. When the lowermost wall segment reaches the floor of the airplace, a plurality of hooks around the lower edge thereof are engaged with recessed parts on the bottom of the seat assembly and at the same time the cushioning materials fall down from the ceiling while expanding by themselves whereby the hollow space in the expanded chamber surrounding the passengers is filled with cushioning materials for the purpose of preventing the passengers from the influence of shocks.

    Abstract: An air launchable sonobuoy having two separate liquid chemicals which react pon mixing to form an expanded, rigid foam flotation device. Upon deployment in the air, windflaps release a preloaded plate within a submersible housing and urge the chemicals to mix and foam in an elastic envelope. After water impact, an orifice in the housing permits water to fill the voids at a rate sufficient to allow the housing to remain afloat until foaming and erection of an antenna within the envelope is complete. As the envelope expands, a latch releases it from the housing and permits the housing when flooded to sink to the desired depth determined by the payout length of a cable within the housing connected to the flotation device.

    Abstract: A system for transferring cargo at sea by helicopter includes an automatily activated self inflatable apparatus for reducing the velocity of the cargo if jettisoned or inadvertently dropped into the sea and for keeping the cargo afloat until retrieval may be accomplished. The cargo is lifted by a support sling attachable to a helicopter suspension cargo hook and simultaneously connected to a second sling in parallel to the helicopter through the rapidly deployable retardation and floatation device. Release of the support sling causes the cargo to drop and initiate deployment and inflation of the ribs of the parachute thereby retarding the cargo's descend and providing buoyancy for its floatation.

  • Patent number: 4007895
    Abstract: A system for ejection of a crew member from an aircraft is disclosed. In one embodiment a mass is fired from a mortar or similar ejection device and the mass has attached to it a pendant which is resilient. As the pendant reaches the limit of its length as a result of the motion of the mass, the stretch force therein pulls down the seat pan upon which the crew member is resting and a divestment device is actuated. The crew member is then accelerated upward and out of the aircraft. Once the crew member is clear of the aircraft, the pendant's weak link separates just before the peak loading is reached and the action of the pendant initiates deployment of the parachute. The mass and pendant then separate and carry on out of the area of the pilot in a ballistic trajectory. In a second embodiment of the invention, a slipping clutch mechanism is utilized such that as the pendant runs off the clutch spool, and tightens, the pendant spool begins to rotate against the clutch torque feeding out more line.

    Abstract: A pair of sector-shaped wings stored in a pair of spaced apart elongated housings strapped vertically to the back of the user and adapted to be deployed from the housings utilizing rotatably mounted handles secured to the wings. Each housing has a longitudinal opening through which a wing is packed into a housing and deployed therefrom. Each wing comprises a pliable sheet of material which is secured to its respective housing along one side margin and secured to a rigid strip at another side margin. The strips are pivotly mounted and carry the handles which allow the wings to be manipulated by the arms of the user for accomplishing sky diving maneuvers.

  • Patent number: 3964700
    Abstract: An elongated, cylindrical case has an intermediate partition dividing it into a canister and a housing. A parachute is attached into the housing with deployment means releasable by a timer. After a predetermined time has elapsed, the timer withdraws radial pawls to release an end cap from the housing, allowing the parachute to be deployed. The canister is equipped with a special end cap capable of hermetically sealing the canister so that it may convey any of a variety of cargo via airdrop. This end cap is essentially a cylinder, recessed at both ends. A disk is held adjacent the inner end of the cylinder by a center post that passes through central holes in the cylinder by the disk and is pivoted to a plurality of radial pawls that may be extended or withdrawn by rotation of the center post, so that they may engage a shoulder in the end of the canister. The center post is equipped with means for locking it in one position so that the end cap cannot be removed by accident from the canister.

  • Patent number: 3944169
    Abstract: A hang glider in the form of an aerial wing of airfoil shape is disclosed. The wing is defined by an outer envelope of flexible material inflatable to the airfoil shape and having a plurality of chambers therein each receiving an inflatable bladder. Air inlet openings are provided in the bottom portion of the envelope adjacent the leading edge of the wing. Either the bladders or the chambers are inflated with a gas lighter than air and, during flight, air enters the openings and fills the available space in the others of the bladders or chambers to provide a complete smooth airfoil shape for the wing. Shroud lines are employed to suspend a person beneath the wing during flight.
