| 20090152392 | PARAMETRIC GEOMETRY MODEL FOR A BLENDED WING BODY - Lofting of a Blended Wing Body air vehicle is accomplished by first determining the required payload volume of the air vehicle. The payload volume is then analyzed to determine a list of corner points of the payload volume. The list of points is passed to a Loft Module as keep-out points and a body portion of the blended wing body is established using a faceted minimum volume which encloses all of the provided keep-out points. A trapezoidal wing shape and size is then determined to accommodate aerodynamic performance requirements. A leading edge of the body portion and trapezoidal wing leading edge are trimmed and a trailing edge of the body portion and trapezoidal wing trailing edge are blended. A leading edge elevation is established and with leading edge radius as an input all other point coordinates and all tangents and remaining curvatures to smoothly enclose the payload volume in a first set of aerodynamic sections are defined. The aerodynamic requirements of the trapezoidal wing including Wing Thickness, Camber, Twist and Shear establish a second set of aerodynamic sections and sections in a transition region between the body portion and the trapezoidal wing are then defined. The blended wing body is then lofted based on the first plurality of sections, second plurality of sections and transition sections. | 06-18-2009 |

| 20100252674 | Reducing runway requirement for aircraft - 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. | 10-07-2010 |

| 20130341459 | Compression-lift aircraft - A supersonic aircraft design using compression lift for enhanced cruise performance. Each engine nacelle at mid-span has a vertical wedge at the nose which creates shock waves under the wings. The increased pressure behind the shock waves pushes up on the wings, creating compression lift. The second part of the process is trapping the shocks by some vertical surfaces. The inboard shocks are intercepted by a keel under the fuselage. This causes the reflected shock effect, which increases compression lift. The keel is just wide enough to store the main landing gear's wheel bogies one behind the other. One strut carrying a wheel bogie retracts upward and forward. The other strut retracts upward and backward. This allows tandem bogie storage in the narrow keel, which reduces drag. Outboard shocks are trapped by wingtip fins with pointed noses to reduce shock interference at the point of shock trapping. | 12-26-2013 |
