Abstract:
An aircraft system battery pack is housed in a housing having a removable cover with a window formed therein. A pair of batteries is positioned in the housing. A lamp is mounted in the window of the cover. A pushbutton switch is mounted in the cover and manually depressible from outside the cover. Electrical conductors electrically connect the batteries in series and provide a DC output voltage and electrical conductors electrically connect the batteries in circuit with the lamp and the switch in a manner whereby manual depression of the switch closes the circuit with the batteries and the lamp. The lamp then indicates the power output condition of the batteries.
Abstract:
A pilot's ejection seat is propelled in an upward direction after ejection by employing a high gain signal from a radio altimeter on board an aircraft. The vertically downward high gain vector is inverted by adding 180.degree. to its phase component and providing the resultant signal to an inexpensive gyro or assembly of gyros installed in the seat. The gyros are constantly updated with information concerning the upward vertical direction and upon ejection, the gyros maintain this information for a sufficient period of time to control the ejection seat propulsion system in a manner achieving a vertically upward trajectory that will enable the pilot to clear a disabled aircraft and achieve the orientation necessary to deploy a parachute.
Abstract:
A multi-purpose protective garment is provided for aviators and astronauts. The garment includes inflatable pads which selectively exert pressure on the chest and abdominal areas of the wearer to counteract the effects of high altitude and high G forces which have detrimental effects upon an aviator. The garment includes an integral harness for easily attaching a hollowed backpack frame which not only contains a stored parachute but serves as an oxygen bottle for inflation of the pads as well as providing an emergency oxygen supply for the wearer.
Abstract:
Aviator harness fittings are pneutically actuated by a central device including a pressurized gas cartridge. A firing pin may mechanically pierce the cartridge or automatic ballistic actuation of the firing pin may be accomplished by SEA WARS gas-generating devices when the latter contacts sea water. The ballistic actuation of the present invention requires two separate SEA WAR gas-generating devices to fire simultaneously thereby minimizing the chance of false actuation.
Abstract:
An aviator suit is provided with a sewn-on channel of hook and eye material which encloses an elongated line that extends to a floor bracket by a shear fastener. The enclosed line prevents snagging on objects within a cockpit and becomes easily removed when the VELCRO gives way during ejection when forces are exerted upon the enclosed channel line. A simplified snubber plug is releasably clamped to the aviator's seat and becomes released after the aviator has cleared a cockpit.
Abstract:
Threaded shafts engage threaded fittings at the top and bottom of a pilot's ejection seat. A motorized gear train selectively rotates the threaded shafts so as to adjust the fore-aft position of a seat while maintaining it behind a pre-designed emergency ejection path from a cockpit.
Abstract:
An assembly for restraining the upper limbs of an occupant of a seat, particularly an aircraft ejector seat, includes a storage unit which is adapted to be fixedly secured to an upper back portion of the seat. The storage houses a pair of movable cover members and first and second bladder units. The cover members and bladder units are connected by means of straps to a quick release mechanism which mates with a corresponding fitting carried by the occupant and then to a fixed structure adjacent the seat. When it is desired to deploy the restraint assembly, a tension is applied to the straps which causes the cover members to extend around opposite sides and laterally inward of the occupant's body, about respective arms of the occupant, and the bladder units to extend about the occupant's neck. The bladder units are then inflated so as to permit undesirable movement of the occupant's head.
Abstract:
The harness of a pilot may be custom fitted in the field by temporarily fitting front and back vest panels. The vest includes strips pre-sewn thereon which serve as passageways for harness straps. The straps are tightened and temporarily secured to the vest so as to closely conform to the torso of the pilot. The vest is then removed so that the front and back panels may be sewn together as well as the temporarily secured straps. The result is a harness/vest combination which will conform securely to the torso of a pilot.
Abstract:
A lock pin mechanism for a negative "G" pilot's harness includes a contoured strap lug received within a metal keeper. A lock pin passes through the keeper and engages the lug. A bearing surface exists between the lug and the keeper so that high upward forces exerted on a negative "G" strap are transmitted to the strap lug but become shared between a lug-pin interface as well as a lug-keeper interface. Thus, binding frictional engagement between pin and lug is avoided so that safe and secure withdrawal of the pin is achieved when required.
Abstract:
A backpack for a wearer in an aircraft has a rigid housing releasably storing equipment for bailing out of the wearer from the aircraft over land, water and all types of surfaces under all types of surface conditions and for survival of the wearer during, upon and after descent.
