| 20090014596 | LONG ENDURANCE AIRCRAFT HAVING MORPHING WING CONFIGURED TO CHANGE SHAPE - A long endurance powered aircraft includes a central spar, a propeller coupled to the central spar, and a wing coupled to the central spar. The wing includes a first spar and an opposing second spar. Leading ends of the first and second spars are coupled to the central spar and trailing ends of the first and second spars selectively diverge from the central spar to define a morphing wing configured change shape to optimize aircraft flight parameters in response to changes in at least one flight condition. | 01-15-2009 |
| 20090050749 | Aircraft wing spoiler arrangement - An aircraft wing comprising an upper surface; and two or more spoilers pivotally attached to the upper surface, wherein at least two adjacent ones of the spoilers are separated by a gap, and wherein the width of the gap is: greater than 1 cm; and sufficiently small to choke the flow of air through the gap such that for at least one flight regime with the adjacent spoilers deployed, the average air flow speed through the gap is less than 10% of the true air speed. | 02-26-2009 |
| 20110062289 | Envelope With Gas Management System For Lighter-Than-Air Aircraft - An envelope holds gas in a lighter-than-air aircraft. The envelope has an outer shell, an inner wall, a compressor, and a valve. The outer shell has an upper surface, a lower surface, a leading edge, a trailing edge, opposing side surfaces, and an airfoil-shaped lateral cross-section. The inner wall divides the outer shell into high and low pressure chambers. The compressor is disposed between the high and low pressure chambers and controlled to selectively force gas from the low pressure chamber to flow into the high pressure chamber. The valve is disposed between the high pressure chamber and the low pressure chamber and controlled to selectively permit gas from the high pressure chamber to flow into the low pressure chamber. | 03-17-2011 |
| 20120104183 | OPTIMAL WING PLANFORMS FOR REDUCING THE INDUCED OR TOTAL DRAG OF THE WING OF AN AIRCRAFT DRIVEN BY WING-MOUNTED TRACTOR PROPELLERS/ROTORS - The disclosure relates to Aeronautics, more particularly relating to wing planforms that reduce wing drag substantially in aircraft driven by propellers or other rotors in tractor configuration. An aircraft comprising a wing and propeller system ( | 05-03-2012 |
| 20080237403 | METAL INJECTION MOLDING PROCESS FOR BIMETALLIC APPLICATIONS AND AIRFOIL - A method of producing an airfoil including the steps of providing a first preform having a metallic powder of a first alloy, the first preform defining an airfoil body having curved pressure and suction sides. A tip cap is disposed between the pressure and suction sides of the airfoil at a radially outer end of the airfoil body. A partial height squealer tip extends radially outwards from the tip cap to provide a second preform that is a metallic powder of a second alloy different from the first alloy. The tip cap is formed in the shape of an extension of the squealer tip. The first and second preforms are sintered to consolidate the metal powders. An airfoil according to the method is also disclosed. | 10-02-2008 |
| 20100025541 | LIFTING FOIL - A lifting foil having a lower trailing course having a margins and an upper leading course margins connected in a manner to enhance lift of the foil. | 02-04-2010 |
| 20100258681 | Flying Saucer - This invention provides a kind of flying saucer, which pertains to aviation vehicles area. It includes capsule, operating and controlling system, energy electrical system, inner-cabin facilities, fuel system, start-up system and ignition system. On capsule there fix capsule motion direction regulating equipment and capsule whirling steadiness regulating system. On capsule there fix fuel tank. On fuel tank there is a fuel tube. On capsule there fix a flywheel jet engine also, which includes flywheel spindle, flywheel and jetting device. Flywheel spindle connects to capsule. Flywheel is fixed on flywheel spindle. In the peripheral region of flywheel there fix several jetting devices. It can realize vertically taking off and landing. Capsule motion direction regulating equipment and capsule whirling steadiness regulating equipment are fixed on capsule. It can be simply handled, and it flies smoothly and steadily. It is convenient to change directions. In flight, flying saucer produces a spiral airflow whirling around capsule and simultaneously spirally propelling toward the bottom of capsule, which can boost the propelling speed toward the bottom of capsule. This invention has advantages of its high flying speed; it's flexible in changing directions; its high security; its low fuel costs, and so on. | 10-14-2010 |
| 20120305714 | ANNULAR AIRBORNE VEHICLE - An airborne vehicle having a wing-body which defines a wing-body axis and appears substantially annular when viewed along the wing-body axis, the interior of the annulus defining a duct which is open at both ends. A propulsion system is provided comprising one or more pairs of propulsion devices, each pair comprising a first propulsion device mounted to the wing-body and positioned on a first side of a plane including the wing-body axis, and a second propulsion device mounted to the wing-body and positioned on a second side of the plane including the wing-body axis. | 12-06-2012 |
