  • Publication number: 20160311512
    Abstract: A wedge frame for an aircraft that provides tailstrike angle enhancement. The wedge frame has converging, non-parallel faceplanes that tilt a rear portion of the aircraft fuselage upward in order to prevent or reduce risk of the tail of the aircraft striking the ground during takeoff and landing. A method to prevent or reduce risk of the rear portion of an aircraft from striking the ground during takeoff and landing by using a wedge frame having converging, non-parallel faceplanes to tilt upward the rear portion of the aircraft.

  • Publication number: 20150367944
    Abstract: Systems, methods, and apparatus for permitting evacuation of an aircraft following a water landing are disclosed. In one or more embodiments, the disclosed method involves deploying, an evacuation unit, from inside a storage housing located proximate a door of the aircraft. In one or more embodiments, the evacuation unit comprises at least one step and a wave fence. In at least one embodiment, when the evacuation unit is fully deployed, at least a portion of the wave fence is in water-tight contact with at least a portion of a frame of the door such that water flow into the aircraft is prevented and/or inhibited.

  • Patent number: 7431366
    Abstract: The invention provides an innovative and practical new class of crossover motor vehicles for carrying passengers and for carrying cargo in a cargo or pickup bed, while still being of sufficiently small dimensions as to be garage-able in many home garages. Representative embodiments can carry 6 or 7 or 9 persons in comfortable seats all with adjacent or facing seats for companions; plus substantial varied cargos, which can potentially include sporting or recreational equipment such as bicycles or a powered waterscooter or snowmobile or motorcycle; camping gear including a 9-person tent; furniture such as a Queen bed set; appliances such as a washer and dryer; utility equipment such as a snowblower or riding lawnmower; or substantial quantities of items such as lumber, bark or fertilizer.

  • Publication number: 20070114327
    Abstract: A wing load alleviation system and method for alleviating the lift-inducing structural-bending force (i.e., moment) experienced by each of the wings of an aircraft. The apparatus includes a deployable panel and an actuator mounted in each wing. The actuators are responsive to a command generator. The actuator is mounted inside the wing and the panel is mounted flush with an outer surface of its respective wing. Each panel can be moved between a retracted position, where it has no affect on airflow moving over the wing, to a deployed position in which it deflects air off of the wing. Each panel is preferably located at a span-wise location at least about halfway along the length of the wing toward the wing tip, and more preferably at least in part outboardly of the outboard-most trailing edge device in the wing. The apparatus effectively shifts the lift-inducing structural-bending forces experienced by the wing more inboard towards the fuselage.

  • Publication number: 20070108347
    Abstract: An aircraft fuselage includes a tubular shell having a centerline axis, opposite ends, and a cross-section having a radius R(?), where ? is the angular coordinate of a cylindrical coordinate system, a curvature Curv(?), where Curv(?) is the inverse of a local radius of curvature of a surface of the shell, and a circumferential shape that varies radially by no more than ±7% from that of an elliptical cross-section at substantially every station along the centerline axis between the nose and tail ends thereof. The weight of the shell is minimized by “tailoring,” i.e., optimizing, at least one structural attribute, expressed as a function of ?, associated with every element of the shell, such that the weight of the shell required to react a design load incident thereon is less than that required to react the same design load, but wherein the same structural attribute has not been so tailored.

  • Publication number: 20050133308
    Abstract: A mobile platform galley cart storage and retrieval system includes a plurality of joined walls defining a galley area. A plurality of mobile carts are stored in the galley area, including at least a first side-by-side subgroup of carts and a second-side-by-side subgroup-of carts positioned above the first subgroup. An optional third subgroup is positioned above the second subgroup. An automatic transfer system lifts and horizontally transfers carts to predetermined storage locations on racks supporting each elevated subgroup of carts. The carts are stored in either randomly accessible locations or in first-in/last-out locations.

  • Publication number: 20050061916
    Abstract: A fuselage for an airplane comprising a first side of the fuselage having a first curvature; and a second side of the fuselage having a second curvature; wherein the first curvature is different from the second curvature at a substantially vertical cross section of the fuselage. The invention can also be characterized as a cross section of an airplane comprising a first side of a fuselage with a first curvature; a second side of the fuselage with a second curvature that is coupled to the first side of the fuselage; a storage compartment within the fuselage; a seat within the fuselage; and an aisle within the fuselage; wherein the first curvature is different from the second curvature. The invention can reduce or eliminate sonic boom when applied to a supersonic airplane such as a supersonic business jet with a long slender fuselage.

  • Patent number: 5992797
    Abstract: An improvement to a subsonic passenger aircraft is provided. The passenger aircraft has a fuselage including a main passenger seating deck (14) including forward, middle, and aft regions. The fuselage includes an upper forward deck (16) located above the main passenger seating deck forward region and accessible thereto. Both the main deck and upper forward deck having doors (30), (26) therein for passenger and supplies ingress and egress. The fuselage includes an aft upper deck (18) located above the main passenger seating deck aft region and accessible from the main deck. An upper middle region (20) is located above the main deck middle region. In one embodiment, the upper middle region (20) is of a height elevationally less than either of the forward and aft upper decks. The cross-sectional area of the fuselage at the upper middle region is less than the cross-sectional area of the fuselage at either the forward upper deck region or the aft upper deck region.
