Methods are provided by which a treatment fluid (e.g., a liquid corrosion inhibitor) may be applied onto the interior surfaces of an aircraft fuselage. The methods include (a) deploying an automated guided vehicle (AGV) comprising a carriage assembly and a robotic spray system carried by the carriage assembly within the interior of the fuselage, (b) closing the cabin door opening of the fuselage with the AGV positioned therewithin, and (c) operating the AGV so as to move within the fuselage along a longitudinal axis thereof to spray the treatment fluid onto the surfaces thereof.

The present invention relates to an aerospace vehicle comprising an airplane or spacecraft, operatively coupled to an airship balloon containing lighter than air gas adapted to elevate the vehicle. A control system adapted to deflate the balloon upon reaching a predetermined altitude by directing the gas for powering the vehicle at greater speed. The balloon can be re-inflated for decreasing the speed of the vehicle upon reaching a destination and deflated in a controlled manner for landing the vehicle or disengaged from the vehicle upon transferring the gas from the balloon to a propulsion system of the vehicle.

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.

Methods and apparatus for an adaptable solar airframe are provided herein. In some embodiments, an adaptable solar airframe includes an expandable body having an aerodynamic cross-section that reduces parasitic air drag at any given thickness of the body, further being able to change its shape in flight in response to changes in the relative position of the sun; and a flexible solar PV system attached to the surface of the expandable body.

Disclosed is an invention related to a waterproof unmanned flying apparatus, which is waterproof or water resistant and can perform in inclement weather conditions. The flying apparatus comprises of a main frame covering the outer structure of the flying apparatus that is constructed out of a single piece or multiple pieces which are fused together or mechanically attached to create a watertight seal. A centralized frame can be configured in numerous layouts to include the size and number of rotor blades. The flying apparatus can be used in various applications such as a training device, an aerial photography, and any other event for which the flying apparatus would be required to fly in or around water. The flying apparatus protects expensive internal electrical components that would normally be destroyed by water and moisture. Furthermore, the flying apparatus can be attached with devices for providing features intended for user's consumption.

A mechanism(10) arms, disarms, and activates an airplane emergency evacuation system having a slide with one end connected to a girt bar (16). The mechanism includes floor fittings (18) mountable below and at each edge of the airplane door (14). Each floor fitting includes a base (32) defining a notch (40) for receiving the girt bar and a pawl (42) mounted to the base. The pawl rotates relative to the base from a locked position preventing removal of the girt bar from the notch, and to an unlocked position permitting removal of the girt bar. Support fittings (20) mountable to the door, engages the floor fittings when the door is closed and locked. A first jaw (58) extends downwardly to one side of the notch, and faces generally towards the notch from the support fitting. First and second linkage members (60) and (70) connect to one another and rotatably mount to the support fitting. A second jaw (94) extends from the second linkage member and faces generally towards the first jaw. The mechanism operates to rotate the second jaw towards the first jaw to capture the girt bar therebetween, and to rotate the pawl to the unlocked position to disarm the system and allow normal use of the door. To arm the system, the second jaw is rotated in the opposite direction which releases the girt bar and causes the pawl to securely lock the girt bar to the floor of the airplane.

A variable geometry lighter-than-air craft which can change from a buoyant airship to a heavier-than-air craft by changing shape. The craft has a flexible envelope filled with helium or other lifting gas. Releasing or tightening the adjusting lines changes the envelope shape by adjusting the internal dimensions and extending or withdrawing wing expansion sections. The craft's shape can change from an ovoid shape for lighter-than-air flight to a winged shape for heavier-than-air flight. Controlling the craft's speed and trim regulates the aerodynamic lift.

An aircraft is constructed of an airfoil shaped inflated involucrum of lightweight gas-impervious plastic film. The airfoil is maneuverable to attain forward self-propulsion upon ascent as well as descent. The gases contained in the involucrum are heated by solar radiation to reduce craft density with the upper surface of the airfoil being translucent and the lower surface of the airfoil interior mirrored for concentration of the radiant energy upon an interior cylindrical black spar. A honeycomb reradiation barrier is provided beneath the translucent surface. In one embodiment a large volume involucrum is changeable in camber to maximize forward propulsion. The craft may be utilized to suspend a large fog broom for the purpose of condensation of water vapor. In a further embodiment a manpowered inflatable craft is formed with a flexible longitudinal medial fold which separates the airfoil into wing segments. Each segment includes a passive trailing zone. When the wing segments are oscillated about the medial fold, the craft is propelled by ciliary thrust.
