    Abstract: A method of supersonic thrust generation includes generating a thrust supersonic exhaust plume (522) having a first average velocity from an engine (500), and expelling a bypass exhaust plume (532) having a second average velocity from the engine, the first average velocity greater than the second average velocity, so that the bypass exhaust plume inhibits coalescence of an engine exhaust plume compression shockwave (536).

    Abstract: An airfoil body may include a plurality of tubercles along a leading edge of the airfoil body and a plurality of crenulations along a trailing edge of the airfoil body, wherein at least one of a position, a size, and a shape of the plurality of tubercles and the plurality of crenulations varies in a non-periodic fashion. The non-periodic fashion may be according to a Fibonacci function and may mimic the configuration of a pectoral fin of a humpback whale. The tubercles and crenulations may be defined with respect to a pivot point. The spanwise profile, including the max chord trailing edge curvature, may closely follow divine spirals and related Fibonacci proportions. The spanwise chord thickness may vary in a nonlinear pattern. Related methods are also described.

    Abstract: The lift and drag performance of all vehicles is strongly influenced by viscous effects, and in turn, laminar separation bubbles. This application employs an effective fluid boundary layer control strategy that reduces parasitic drag, allows for more usable angles of attack, and delays or stops separation. In the approach of this application, the control surface effectively uses the Magnus effect to delay or stop a separation bubble from forming, which can increase lift, reduce drag, and delay degrees of stall by directly manipulating the velocity gradient in the fluid boundary layer.

    Inventor: KROO, Ilan

    Abstract: A safe, quiet, easy to control, efficient, and compact aircraft configuration is enabled through the combination of multiple vertical lift rotors, tandem wings, and forward thrust propellers. The vertical lift rotors, in combination with a front and rear wing, permits a balancing of the center of lift with the center of gravity for both vertical and horizontal flight. This wing and multiple rotor system has the ability to tolerate a relatively large variation of the payload weight for hover, transition, or cruise flight while also providing vertical thrust redundancy. The propulsion system uses multiple lift rotors and forward thrust propellers of a small enough size to be shielded from potential blade strike and provide increased perceived and real safety to the passengers. Using multiple independent rotors provides redundancy and the elimination of single point failure modes that can make the vehicle non-operable in flight.

    Abstract: A bidirectional flying wing maximizes efficiency and reduces sonic boom during supersonic flight. The flying wing has bilateral symmetry across two perpendicular planes and a substantially isentropic compression bottom surface that minimizes the shock wave projected downward during flight. The flying wing may be rotated to provide a high aspect ratio and a low sweep angle during subsonic flight. The flying wing may be rotated to provide a low aspect ratio and a high sweep angle during supersonic flight.
