| Application No. | Application Title | Issue Date |
| 20110114797 | Fail-Operational Multiple Lifting-Rotor Aircraft A rotorcraft having multiple rotors, and wings that provide lift in forward flight, has a mechanical coupling between rotors that can be disengaged and optionally reengaged, during flight. The coupling, which can prevent a failure of one rotor from interfering with rota... | 05/19/2011 |
| 20110036955 | Aircraft with Integrated Lift and Propulsion System A vertical take off and landing (VTOL) aircraft is designed to be so efficient that it can be commercially competitive with runway dependent aircraft operating in a range of 100 to 1000 miles. Improvements include a high efficiency tilting rotor and wing design that ena... | 02/17/2011 |
| 20100327123 | Rotorcraft with Variable Incident Wing A twin-rotor side-by-side compound rotorcraft has a fuselage and variable incident wing assembly that pivots relative to fuselage. The aircraft also has landing gear assembly and a tail fin assembly. The variable incident wing assembly is pivotally attached to the fusel... | 12/30/2010 |
| 20100276549 | Fail-operational multiple lifting-rotor aircraft A rotorcraft having multiple rotors, and wings that provide lift in forward flight, has mechanical coupling between rotors that can be disengaged and optionally reengaged, during flight. The coupling can, which can prevent a failure of one rotor from interfering with ro... | 11/04/2010 |
| 20100230547 | Stop-rotor rotary wing aircraft Systems and methods for transitioning an aircraft between helicopter and fixed wing flight modes are provided. In one embodiment, an aircraft comprises a plurality of wings each having a spar and a flap; a flap actuator configured to move the flap with respect to the sp... | 09/16/2010 |
| 20090283644 | CONTROL LEVER ASSEMBLY FOR A TILT-ROTOR AIRCRAFT A control lever assembly for a tilt-rotor aircraft, comprises at least one control lever which is movable relative to a control lever support. The control lever support has a rotational position that varies in correspondence with the tilt of the rotor of the aircraft. F... | 11/19/2009 |
| 20090266942 | Tilt outboard wing for tilt rotor aircraft Tilt-rotor aircraft experience increased efficiency and fuel economy by including wing extensions outboard of the tilting nacelles. Stall and buffeting during conversion from rotor-born hover to wing-born forward flight are reduced to an acceptable level using wide chor... | 10/29/2009 |
| 20090045295 | Vertical/Short Take-Off and Landing Aircraft A vertical/short take-off and landing aircraft with a single proprotor assembly that has a pair of inline counter-rotating rotors. Two inline counter-rotating engines are directly connected to the rotors. One engine is shut down in horizontal flight to improve efficienc... | 02/19/2009 |
| 20060097103 | Method and apparatus for vehicle control using variable blade pitch An integrated propulsion and guidance system for an aircraft or other vehicle includes an engine coupled to a propeller via a driveshaft to produce propulsive force. One or more of the propeller blades are pivotably mounted with respect to the hub of the propeller. A co... | 05/11/2006 |
| 20060032971 | TAILBOOM-STABILIZED VTOL AIRCRAFT A disclosed flying craft includes a suspension structure having a first end and a second end, a lift unit, and a payload unit. The lift unit includes a nacelle and a tailboom, and pivotally couples to the first end of the suspension structure, and a payload unit couples... | 02/16/2006 |
| 20060016927 | Method and apparatus for rotatably supporting movable components, including canards Methods and apparatuses for rotatably supporting movable components, including canards. An apparatus in accordance with one embodiment of the invention includes an airfoil configured positioned external to an aircraft fuselage. A connecting portion can depend from the a... | 01/26/2006 |
| 20050230519 | Counter-quad tilt-wing aircraft design The invention consists of a specific, matched arrangement of aeronautical elements which (1) eliminates aerodynamic interference of, and (2) adds variable-cycle propulsion to, the level flight mode of a four-propulsor tilt-wing VTOL (vertical takeoff & landing) aircraft... | 10/20/2005 |
