Patent number: 6837463Abstract: A wing for a traction kite, etc comprises a plurality of cells formed by chordwise-extending ribs (3), valved openings (6) to the cells allowing ram air to inflate the wing. By changing the initial cut-out of the material forming the cells near wing tips (7, 8), compared with that of the cells central to the wing, it is possible to alter the aerodynamic forces at wing tips (7, 8).

Patent number: 6808144Abstract: A parafoil recovery system capable of autonomously controlling the descent profile of a payload to a recovery area and maneuvering the parafoil to execute a soft landing in the recovery area is disclosed. A descent profile management system determines wind speed and direction, altitude, heading, and position of the payload based on sensor input. The descent profile management system also determines a gliding flight path profile from the launch point to the desired recovery area. A flare and stall maneuver is executed at the end of the landing sequence by braking the parafoil to slow the vertical descent speed and groundspeed for a soft landing. The pitch attitude of the payload can be adjusted by the descent profile management system to prevent nose-first impact with the ground. The parafoil canopy is released from the payload upon touchdown to prevent the canopy from dragging the payload on the ground after landing.Type: GrantFiled: December 26, 2002Date of Patent: October 26, 2004Assignee: Lockheed-Martin CorporationInventors: Leland M.

One or more holonomic ports are formed in at least one of the third skins and a jet port is defined by at least a portion of one or more of the spors being open at its aft end.Type: GrantFiled: March 16, 1987Date of Patent: September 20, 1988Inventor: Stephen J. Sutton

Patent number: 4768739Abstract: A warning and signaling system includes a kite attached to a flexible tether rope wherein one end of the rope is secured to a person or a lifeboat. The kite is made from a material having high visibility and includes radar reflective material. The tether rope may carry an antenna for a radio transmitter and receiver. An optional inflatable chamber provides rigidity to the kite. The kite may be provided with a tail having radar reflective swatches attached thereon.Type: GrantFiled: December 15, 1986Date of Patent: September 6, 1988Inventor: Robert A. Schnee

Patent number: 4705238Abstract: Upper and lower rectangular canopies are connected by a plurality of transversely spaced vertical airfoil shaped ribs to define a plurality of longitudinal air flow chambers. Suspension lines are connected to selected ones of the ribs and are arranged in longitudinally spaced and transversely extending rows. Cells are defined which consist of a plurality of adjacent chambers between any two transversely adjacent suspension lines. Some of the cells have three chambers while others have two chambers. The suspension line dimensions and trim angles are used to impart multiple pressure centers and different arc anhedral shapes to improve various characteristics of the parachute including opening, stability and accuracy.Type: GrantFiled: July 8, 1986Date of Patent: November 10, 1987Inventor: William L. B. Gargano

Patent number: 4562981Abstract: A parachute assembly includes a canopy, a harness connected to the canopy by lines, the canopy having an apex and a basal perimeter. Envelopes in the canopy defined by a plurality of generally triangular inflatable gussets extend from adjacent the apex to adjacent the basal perimeter and taper outwardly towards the basal perimeter. The assembly includes a source of pressurized gas and flexible conduits connecting the gas source to the gussets. One or more valves for releasing the gas from the source through the conduits to the inflatable envelopes and manually operable valves to release the pressurized gas into the conduits and envelopes to inflate the gussets.Type: GrantFiled: June 20, 1983Date of Patent: January 7, 1986Inventors: David S. Smith, Geoffrey A. Smith

Patent number: 4406433Abstract: The air scoop opening at the leading edge of a flexible, ram-air inflated airfoil canopy, is framed between curved lip sections extending tangentially from the upper and lower surface members of the canopy to prevent airflow separation adjacent the leading edge and the drag producing effect thereof. A baffling curtain extends across the air scoop opening.Type: GrantFiled: December 18, 1980Date of Patent: September 27, 1983Assignee: Aerovironment, Inc.Inventors: Robert L. Radkey, Bart D. Hibbs

Patent number: 4379534Abstract: 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.Type: GrantFiled: March 2, 1981Date of Patent: April 12, 1983Assignee: The United States of America as represented by the Secretary of the NavyInventors: Ralph A. Miller, Randall F. White
