20080210808INTEROPERABLE AERIAL REFUELING APPARATUS AND METHODS - Interoperable aerial refueling apparatus and methods are disclosed. In one embodiment, a receptacle configured to fluidly receive a terminal portion of a refueling boom is coupled to a refueling drogue. A retainer is coupled to an aircraft that removably retains the receptacle when the aircraft is refueling another aircraft configured to directly engage the boom. The receptacle releases the receptacle when the terminal portion of the boom engages the receptacle so that an aircraft that receives the refueling drogue may be refueled. In another embodiment, a method includes providing fuel to a first receiving aircraft that receives fuel by directly coupling to an end of a refueling boom. The method further includes, while the tanker aircraft is in flight, configuring the boom to supply fuel to a second receiving aircraft having a refueling probe operable to receive fuel from a drogue.09-04-2008
20080223978VARIABLE FLUID INTAKE WITH RAMP AND INFLATABLE BAG - Methods and apparatus for a fluid inlet according to various aspects of the present invention comprise a housing and a ramp at least partially within the housing. The housing and the ramp define a passage through which air may flow to the engine and a cavity on the opposite side of the ramp from the passage. The ramp is moveable within the housing to change the size of the passage and the cavity. The system further comprises a seal substantially disposed across the cavity.09-18-2008
244021000 Cylindrical rotor sustained 1
20120160955Hybrid Rotor - A hybrid rotor for an aircraft includes a Magnus rotor rotatable around a Magnus rotor axis and a transverse flow rotor that is kept rotating around an axis of rotation and has a number of axially extending rotor blades that are actuatable to rotate around the axis of rotation and are configured stationary relative to the tangential angle position. The Magnus rotor is located within the transverse flow rotor and has an axis extending in the direction of the axis of rotation. The guide mechanism has a housing segment partially surrounding the transverse flow rotor in the circumferential direction. The housing segment has an adjustment mechanism and is deflectable relative to the Magnus rotor axis. The housing segment is aligned such that the transverse flow rotor generates a propulsion force and causes a transverse flow onto the Magnus rotor to generate lifting force by way of a Magnus effect.06-28-2012

20110079677Ornithopter - The claimed invention is an ornithopter with three improvements over previous designs. First, it has a more efficient wing. Instead of using a heavy bracing rod to regulate the flexibility of the wing, it uses a lightweight cable tension system. Second, it has a steering mechanism that separates the servos from the tail itself, reducing the likelihood of damage in the event of a crash. Third, the ornithopter has a modular design, which allows more control over the external appearance of the model. Various bodies can be used with the same drive mechanism, and it permits the individual hobbyist or the kit manufacturer to produce additional body designs without having to take on the complex task of designing a new flapping mechanism.04-07-2011

20090218438VTOL personal aircraft - A vertical take-off and landing (VTOL) aircraft comprises (1) a fuselage having a front end, a rear end and two lateral sides, the fuselage defining a substantially horizontal central longitudinal axis of the aircraft; (2) an aircraft tail arranged at the rear end of the fuselage and including a rudder and an elevator on each side of the fuselage with movable surfaces for controlling the aircraft; and (3) a wing on each side of the fuselage having a front edge, a trailing edge and an upper surface extending from the front edge to the trailing edge. According to the invention, means are provided for increasing the speed of an airstream flowing over the upper surface of each wing, and an air deflector is disposed on each side of the fuselage between the trailing edge of each wing and the aircraft tail. These deflectors each have a deflection surface to deflect downward the airstream flowing over the upper surface of the wing to act as a “brake” to the forward motion of the aircraft and to provide additional lift so that the aircraft may hover.09-03-2009
