    摘要: A truss beam comprised of a plurality of joined convex-curved rods with self-aligning adapters (SAA) adhesively attached at each end of the truss beam is disclosed. Shear web panels are attached to adjacent pairs of rods, providing buckling resistance for the truss beam. The rods are disposed adjacent to each other, centered around a common longitudinal axis, and oriented so that adjacent rod ends converge to at least one virtual convergence point on the common longitudinal axis, with the rods' curvature designed to increase prevent buckling for the truss beam. Each SAA has longitudinal bores that provide self-aligning of the rods in the SAA, the self-aligning feature enabling creation of strong adhesive bonds between each SAA and the rods. In certain embodiments of the present invention, pultruded unidirectional carbon fiber rods are coupled with carbon fiber shear web panels and metal SAA(s), resulting in a lightweight, low-cost but strong truss beam that is highly resistant to buckling.

    摘要: An ultralight helicopter has a pair of counter-rotating rotor assemblies which in combination yield zero net angular momentum when rotating at equal speeds. A single motor drives both rotors through a counter-rotating bevel gear set coupled to a pair of concentrically nested output shafts. In an alternative embodiment, the motor is coupled to the rotors through a hydraulic drive system which includes a hydraulic pump and at least one hydraulic motor driving each of the rotor assemblies. The pilot is advantageously suspended in a "hang-glider" type harness from a single hang point positioned proximate the center of lift of the helicopter. A control bar is fixedly mounted to the frame and is grasped by the pilot suspended in the harness. The pilot maneuvers the helicopter in both the pitch and roll directions by manipulating the control bar. The pilot shifts his own center of gravity relative to the center of gravity of the helicopter while grasping the control bar to thereby maneuver the helicopter.

    摘要: 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.

    摘要: A novel freely grasped hand-sail is described, which consists essentially of two profiled airfoil surfaces inclined towards each other at an angle between about 180.degree. and 120.degree., the leading edges of this hand-sail also forming an angle between about 180.degree. and 120.degree.. In one embodiment, the airfoil consists of sails kept rigid by aerodynamically preformed battens, which sails are stretched symmetrically between two masts and a middle boom. The freely grasped sail turns around its horizontal axis when set against the wind, and stabilizes itself at a certain turn, whereby the section that is more vertically directed yields forward thrust forces, to propel, for example, a sailboard, and the section that is more horizontal in this position mainly yields upward thrust forces to compensate the weight of the hand-sail and the rolling moment exerted on the sail. Wave-jumping while wind-surfing, in particular, can be made easier with the help of this hand-sail.

    摘要: An ultralight aircraft of lightweight minimal construction includes a collapsible Rogallo type wing from which a hang cage is suspended by a main hinge assembly. The wing includes a longitudinal keel of lightweight tubular construction, leading edge members and a cross brace. A flexible lifting panel is secured along and between the wing members to define a lifting surface. The hinge includes a pitch hinge bracket having an upper longitudinal sleeve in which the keel is clamped. A ball joint connection secured to the bracket is connected to upwardly extending hang cage struts by means of hinge connecting plates to permit free rotation of the wing about a spanwise axis extending longitudinally through the cross brace. Rotation of the wing without pilot intervention induced by positive or negative wind gusts striking the flexible wing panel causes the angle of incidence between the wing and hang cage to vary so that the wing presents a relatively constant angle of attack to relative wind enabling the aircraft to be essentially stall free during flight. A cable and spreader tube arrangement interconnecting forward and trailing ends of the keel to the cross brace undergoes tension and compression loading to distribute bending stress acting on the keel during excessive wind loading to other parts of the aircraft.

    摘要: A human powered hang glider (10) has a fixed wing portion (12) and a pair of movable wing portions (14, 16). Flexible sheet material (26, 28) is connected to trailing edges (30, 32) of the movable wing portions (14, 16). A support structure (34, 36) for the flexible sheet material (26, 28) overlies each flexible sheet material (26, 28). Elastic bands (52) and wires (74, 76) are connected in opposing relationship to the movable wing portions (14, 16) to allow reciprocation of the movable wing portions (14, 16). When the flexible bands (52) cause upward movement of the movable wing portions (14, 16) the flexible sheet members (26, 28) move away from their associated support structures (34, 36), allowing air to pass through the support structures (34, 36). When pilot (70 pulls on wires (74, 76) to move the movable wing portions (14, 16) downward, the flexible sheet portions (26, 28) move against their associated support structures (34, 36) to provide increased lift from the movable wing portions (14, 16). In a typical flight, these movements are performed occasionally, and the hang glider is otherwise launched, flown and landed in a conventional manner.

    摘要: An aircraft, either rigid-wing or a collapsible hang-glider, is provided which is a bi-plane of apparent annular-wing construction in plan view, but the wing tips of an anhedral foreplane are separated from and above the wing tips of a dihedral aftplane. In a hang-glider construction the wing tips of the foreplane may be supported above the wing tips of the aftplane by struts, the trailing edges of the foreplane wing tips being supported by the struts above the leading edges of the aftplane wings. Also in the hang-glider, the geometry of the fore and aftplanes can be varied by moving their points of connection to the keel therealong.

    摘要: A high performance hang glider includes a frame to which is attached flexible sail fabric to create a delta-shaped Rogallo wing. The sail is of double thickness throughout a substantial portion of the wing area to provide an envelope inflatable in flight by air entering an intake opening at the nose of the wing and exhausting through nozzles in the underside of the wing tips. A more efficient double-surface airfoil is thus provided which automatically changes its camber in response to changes in speed for optimum performance.

Movement of the bracket also adjusts the billow of the sail and the dihedral of the frame.
