  • Patent number: 7823840
    Abstract: Coanda Effect and lift produced along a surface of an airfoil are increased by ducting compressed fluid from the engine to the surface of the airfoil. An engine produces exhaust gases that are predominantly directed toward an aft end of the aircraft by a cowling or other structure as an exhaust plume. One or more internal ducts extend from the engine to the surface of the airfoil to thereby transmit a compressed fluid from the engine to the surface in order to suppress flow separation along the surface, thereby causing the engine exhaust flow to remain attached to the surface over a wider span. Such structures and techniques may find particular use in aircraft designed to exploit upper surface blowing (USB) techniques and structures for short takeoff and landing (STOL) performance.

  • Publication number: 20100252674
    Abstract: Runway length requirement for take-off and landing of an aircraft is reduced by taking advantage of dynamic lift overshoot, and in some cases, dynamic stall. In take-off and landing, the angle of attack is rapidly increased so that the lift coefficient exceeds the maximum predicted by the steady flow lift curve. By increasing the angle of attack at an appropriate rate, the increased lift coefficient can be maintained, without loss of control, until the aircraft touches down in the case of a landing, or until the aircraft can begin a normal climb, in the case of take-off. A low aspect ratio lifting body is preferred because of its more gradual stall behavior, and the potential to use dynamic stall for further deceleration before touchdown. Vortex fences can be oscillated to delay the onset of stall, and, in cruise, to energize the boundary-layer and reduce drag and/or control roll and/or yaw.

  • Publication number: 20090308981
    Abstract: An aircraft wing assembly comprising: a main wing element; an inboard rib and an outboard rib, each mounted to the main wing element; a bridging structure attaching the inboard rib to the outboard rib; an inboard flap and an outboard flap; and an inboard bearing and an outboard bearing, each mounted to the bridging structure and each engaging a respective one of the flaps. The bridging structure ensures that an accurate distance is maintained between the ribs during installation, and maximises the stiffness of the assembly. Also, the bridging structure can act as a shear plate supporting both the inboard and outboard bearings, thus removing any twisting moment on the ribs.

  • Publication number: 20090292405
    Abstract: A computer implemented method, apparatus, and computer usable program product for symmetric and anti-symmetric control of aircraft flight control surfaces to reduce wing-body loads. Commands are sent to symmetrically deploy outboard control surfaces to shift wing air-loads inboard based on airplane state and speed brake deployment. Surface rate retraction on a wing with peak loads is limited to reduce maximum loads due to wheel checkback accompanied by utilization of opposite wing control surfaces to retain roll characteristics. Airloads are shifted inboard on a swept wing to move the center of pressure forward, thereby reducing the tail load required to perform a positive gravity maneuver. In a negative gravity maneuver, speed brakes are retracted, thereby reducing the positive tail load and reducing the aft body design loads. High gain feedback commands are filtered from wing structural modes above one hertz by a set of linear and non-linear filters.

  • Publication number: 20090146013
    Abstract: Systems and techniques are described for actuating a control surface about a pivot point using variable moments. A bracket having a moment arm is coupled to the pivot point such that the bracket is rotatable about the pivot point to actuate the surface. A power actuator has a shaft coupled to the bracket at a coupling point on the moment arm such that actuation force applied to the shaft results in a moment produced about the pivot point. A linear actuator is configured to adjust the location of the coupling point with respect to the pivot point to thereby changing the moment arm and the moment produced about the pivot point as the bracket rotates. By adjusting the distance between the pivot point and the coupling point, the moments produced about the pivot point can be increased while conserving actuator power.

  • Patent number: 7510150
    Abstract: An energy recovery and storage apparatus especially well adapted for use with flight control surfaces on airborne mobile platforms, such as aircraft. In one form the apparatus includes a ram-like element coupled to a portion of a flight control surface. An accumulator holds a flexible container having a compressible medium contained within the flexible container. The accumulator is in fluid communication with a housing of the ram-like element. When the flight control surface is moved from a deployed to a retracted position, the energy acting on the surface is recovered and stored in the compressible medium as the ram-like element forces fluid from its housing into the accumulator. When the flight control surface is to be deployed again in a subsequent cycle, the stored energy in the compressible medium is used to urge the ram-like element into an extended position, thus assisting in deploying the flight control surface.
