Patent number: 8490915Abstract: The present invention is a ram air rigid structure glider, which uses both ram air inflation and a rigid structure in order to produce the necessary aerodynamic lift to glide through the air. The frame uses two main structural beams, the spar and the keel, to form the general shape of the wings and the tail. The hubs and the network of lines expand the structure laid out by the spur and the keel. The hubs are evenly placed along the spur, and the network of lines are connected and crisscrossed in between the hubs. The sail is a piece fabric wrapped around the frame and has a plurality of cells, which are evenly spaces throughout the sail. The plurality of cells allows the sails to be inflated by ram air pressure. The pilot pod carries the user in the supine position and is attached to the frame.Type: GrantFiled: July 20, 2011Date of Patent: July 23, 2013Inventor: Christopher Paul Farbolin

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). This allows attachment of flying lines (9, 10) to wing tips (7, 8) only, despite the wing having no framing to maintain its spanwise shape under the loading of flying lines (9, 10). The increased aerodynamic forces at wing tips (7, 8) are achieved by making the aerofoil profiles of the cells progressively more reflexive towards wing tips (7, 8), by giving wing tips (7, 8) a residual twist increasing their angle of incidence, by placing the centres of pressure of the cells near wing tips (7, 8) somewhat forward of the pivot line of the wing, etc.Type: GrantFiled: February 9, 2001Date of Patent: January 4, 2005Inventor: Peter Robert Lynn

Patent number: 6824098Abstract: An aircraft is provided having an inflatable parafoil canopy wing and a suspended fuselage. The wing is constructed such that, when inflated, it has an airfoil configuration having leading and trailing edges, thereby producing lift by interaction with air encountered by the leading edge. A central compartment confines a buoyant gas which causes the total volume of the wing to be varied in response to the degree of inflation with the buoyant gas. With sufficient inflation, the aircraft is capable of vertical take-off and landing (VTOL).Type: GrantFiled: May 28, 2003Date of Patent: November 30, 2004Inventor: Gregorio M. Belloso

-
Patent number: 6131856Abstract: A parachute has its suspension lines divided into groups, each group connected to the load through a linear actuator. During descent of the parachute, foreshortening of an actuator or of any group of adjacent actuators causes the parachute trajectory to move in the direction of the foreshortened actuator. Multiple parachutes connected to a single load, with each parachute being connected to the load through an actuator, can similarly have their trajectory controlled. The trajectory of the parachute can also be changed by a system of normally foreshortened actuators which lengthen by actuation. Simultaneous, rapid shortening of all actuators just before ground impact can be used to reduce the descent velocity at ground impact.Type: GrantFiled: June 4, 1998Date of Patent: October 17, 2000Inventor: Glen J. Brown

Patent number: 5620153Abstract: A para-plane (parachute or parafoil airplane), ultralight, or the like is provided with a ducted propeller or fan to increase efficiency of the powerplant, thus reducing the size of the powerplant required. In addition, the duct may reduce propeller and/or engine noise and enhance safety for pilot, passengers and bystanders. Axial vanes may be provided upstream or downstream of the propeller within the duct to counteract the torque effect of the propeller. In another embodiment, a novel inflatable parafoil may be provided to reduce the effort required to initially inflate a prior art parafoil and reduce the incidence of ground strikes of the parafoil. The inflatable parafoil may be inflated with a buoyant gas such as helium or hot air to further reduce ground contacts and provide limited buoyancy to the aircraft.Type: GrantFiled: March 20, 1995Date of Patent: April 15, 1997Inventor: Harold M.

Patent number: 5033698Abstract: The curve profile of the front edge of an air-filled wing or sports kite of a type which is guided from the ground is maintained without the use of any bracing system. This curve profile, which is very important in determining the flight characteristic of the wing, is controlled exclusively by adjusting the various lengths of balance lines. Two symmetrical line bundles or connecting balances radiate from end points of at least two steering lines and are fastened to various points on the wing base. If so desired, central balance lines can be connected to the wing base without intermediate fastenings. The fastening points on the wing base are located chiefly at the front portion of the wing base. The lengths of the various balance lines preferably increase from the side edges to the middle. However, the rate at which the balance line length becomes greater can increase, decrease, or remain constant, at least in certain areas.Type: GrantFiled: September 7, 1989Date of Patent: July 23, 1991Inventor: Wolfgang Schimmelpfennig

Patent number: 4875642Abstract: A light aircraft having a parachute-wing, a single propeller, and means for controlling the direction and speed of the aircraft by simple control lines to the canopy. The carriage is supported by at least two support lines which are secured at attachment points spaced apart laterally with respect to the fore and aft direction of the craft. By ensuring that the support lines are of different lengths a side-to-side suspension bias is created which compensates for the propeller torque reaction.
