82 Partially-inflated rigid-structure glider US13925797 2013-06-24 US09162761B2 2015-10-20 Christopher Paul Farbolin
A partially-inflated rigid-structure glider is a portable or collapsible gliding apparatus that a user can transport in a carrying case. The gliding apparatus includes a rigid yet collapsible frame, tension membranes over both on the wings and tail, and inflatable bladder, a pair of drogue brakes, and a left and right steering mechanism. The pair of drogue brakes is located on opposing sides of the gliding apparatus and create drag on its respective side in order to turn the gliding apparatus either left or right. The user can activate either drogue brake with the left and right steering mechanism, which are control lines attached to each drogue brake. The tension membranes are fitted over the frame so that the gliding apparatus has an airfoil shape in order to create lift with the wings and tail while the gliding apparatus is in flight.

93 Airfoil configuration US264154 1988-11-11 US4927100A 1990-05-22 Eugene F. Provenzo, Jr.; Peter A. Zorn
An airfoil having two (2) basic components, a sail and spoiler, associated with the leading edge of the sail, is herein disclosed. This unique airfoil design has application in flexible wing aircraft (i.e., ultralites), sport parachutes and sport kites. In the typical sport kite embodiment of this invention, there will generally be at least three (3) aerodynamic flight control surfaces: a sail, a keel, and a flexible resilient spoiler attached to the leading edge of the sail. The sail material is itself resilient, however, sufficiently rigid to maintain a preset configuration without the need for struts, spars or extrinsic physical support. A spoiler, which is located along the entire leading edge of the sail, provides additional structural reinforcement to the sail while undergoing controlled deformation in gusty or high winds. The effect of such deformation of the spoiler causes the sail to stall before any physical damage can occur. The resiliency of the spoiler immediately, thereafter, returns the sail to pre-stall configuration, and flight is thereupon resumed without physical damage to the kite. Under certain conditions, it may be desirable to further enhance the inherent physical strength of the sail along the centerline of the sail coincident with the area of the stress imparted upon the sail by the keel. This is readily accomplished by affixing an additional section of sail construction material, or its equivalent, along the topside surface of the sail, opposite to and coincident with the placement of the keel.
94 Tandem seat for ultra light aircraft US542403 1983-10-17 US4600170A 1986-07-15 Terry L. Smith
A tandem seat assembly for ultra light aircraft is disclosed which is interchangeable with a single seat configuration. The assembly, which is primarily used for pilot training, is fitted with dual aircraft controls. The single seat must be removable from an ultra light aircraft in order for the tandem seat assembly as described by this invention to be utilized. The tandem seat assembly is thereby placed in the aircraft such that the center of gravity of the seat assembly is near the nominal center of gravity of the aircraft. Universal attachments of the seat assembly to the aircraft frame allow the seat assembly to be used with a number of different manufacturers of ultra light aircraft models.

The pilot module includes a pilot support shell constructed of a composite material formed to support the seat, legs, and back of a pilot positioned on it and forming an integral part of the fuselage primary structure. The pilot support shell is positioned at least partially forward of the forward end of the boom. At least one reinforcing member is connected to the pilot support shell and to the boom and is constructed in a single piece with the support shell. The reinforcing member also forms an integral part of the fuselage primary structure. An external fairing is positioned behind and attached to the pilot support shell.

97 Arc wing aircraft US146636 1980-05-05 US4415131A 1983-11-15 William R. Bertelsen; William D. Bertelsen
A lightweight, man carrying aircraft including a skeletal fuselage assembly in combination with a primary arc-shaped lifting airfoil having variable camber, incidence angle, and pitching moment and a secondary stabilizing airfoil of a tubular, ring-like configuration. The arc-shaped primary airfoil is superior to traditional low speed airfoil forms due to its high aerodynamic efficiency, inherent design simplicity and strength. The ring-tail assembly, offering marginal aerodynamic lift, contributes significantly to the in-flight stability and safety of the aircraft. Both airfoil members are independently controllable and constructed of a fabric or like skin material which is fitted over a wing assembly and tensioned into an operable airfoil form by the aerodynamic forces of the air during flight. Typically, the wing assemblies are supported and maintained by a lightweight, tubular fuselage structure to which is affixed the propulsion system, control mechanisms and ground support assemblies.

A nose wheel strut assembly is linked to and extends forward of the main wheel landing gear assembly and includes a resilient tension link member.
99 Powered hang glider with reduction drive US869833 1978-01-16 US4262863A 1981-04-21 Charles J. Slusarczyk
A foot-launched and foot-landed hang glider is powered by an internal combustion two-cycle engine drivingly connected through a reduction-drive unit to a large relatively slow-moving propeller. A reduction mount, so referred to because it couples the reduction-drive unit closely to the engine, allows the engine to rotate a large propeller relatively slowly, thus providing more thrust at near-stalling flight conditions. The hang glider, thus powered, also obviates the necessity of being launched from the edge of a precipice and permits flight which is not predicated on the fortuitous selection of favorable air currents.
100 Flying wing US866617 1978-01-03 US4209148A 1980-06-24 Pierre M. Lemoigne
The flying wing comprises a rigid frame and a fabric canopy secured to the frame. The canopy has propelling, braking and steering hyperlift nozzles arranged on the surface of the canopy for canalizing the flow of air rearwardly from the under side to the upper side of the canopy. A support device for the pilot comprises at least two rigid members connected to the frame and extending downwardly from the frame and terminating in a seat for the pilot. Members maintain the rigid members stationary relative to the frame. The canopy has a longitudinal intermediate strip held planar by the frame and two relatively flexible substantially triangular lateral portions on laterally opposite sides of the strip and connected to the latter. The canopy has in plan substantially the shape of an isosceles trapezium the small base of which defines the leading edge of the wing. The intermediate strip has one of the aforementioned nozzles and each of the two lateral portions has two of the aforementioned nozzles.
