287 Device and method for increasing the aerodynamic lift of an aircraft US13855234 2013-04-02 US09193444B2 2015-11-24 Carsten Weber; Markus Fischer; Arne Grote; Rolf Radespiel; Martin Dreyer
A lift arrangement for an aircraft includes an aircraft fuselage section with an outside, an aerodynamic lift body attached to the aircraft fuselage section and extending from the aircraft fuselage section outwardly, and a pair of movably held add-on bodies arranged upstream of a leading edge of the aerodynamic lift body. The add-on bodies include an aerodynamically effective surface and are equipped with incoming airflow to generate vortices that impinge on the aerodynamic lift body, thus leading to an increase in lift on the aerodynamic lift body. Thus the lift generation on a lift body is effectively influenced, in particular to compensate for loss of lift as a result of icing. The add-on bodies are moveable, and, can be moved to a neutral position in which they do not project into the flow around the aircraft, and are thus not effective from the point of view of fluid dynamics.

A number of flow altering devices are arranged so as to adjust the aerodynamic properties of the first longitudinal segment.
293 Hybrid hull for high speed water transport US177328 1998-10-22 US6058872A 2000-05-09 Robert G. Latorre
A catamaran-type boat having two or more demi-hulls that are connected by a wing-shaped superstructure is disclosed. The demi-hulls are further connected by two or more transverse hydrofoils. A tunnel is created between the demi-hulls and the superstructure. The shape of the superstructure takes advantage of the airflow through the tunnel to provide aerodynamic lift. The hydrofoils serve two purposes. The first is to provide hydrodynamic lift, and the second is to cancel wave build up between the hulls. The wave cancellation assists the stability of the craft by providing a relatively flat surface for the wing, to provide stable additional lift through the "wing in ground" effect. The combination of hydrodynamic lift, wave cancellation, and aerodynamic lift decreases the ship's drag and increases its speed.
294 Hybrid Flow Control Method for Simple Hinged Flap High-Lift System US14955913 2015-12-01 US20160280358A1 2016-09-29 John C. Lin; Mehti Koklu

298 Vehicle control device JP2012063835 2012-03-21 JP2013193596A 2013-09-30 ODAJIMA KENJI
PROBLEM TO BE SOLVED: To improve fuel consumption while securing travelling safety of a vehicle.SOLUTION: In a vehicle control device which is mounted in a vehicle and controls a movable aerodynamic member capable of vertically changing force transmitted to a vehicle by receiving traveling wind, when the occurrence of idle is not estimated (S2), a driving wheel is not actually idled (S3), a vehicle is not turned (S4) and a vehicle is not in a braking state (S5), since running safety of the vehicle is secured, ground contact pressure of a wheel is reduced to reduce rolling resistance by setting a movable aerodynamic member to cause lift in which force transmitted to the vehicle is directed upward. When a road surface condition is estimated not to be bad even though a driving wheel is actually idled (S7), when a side slip is prevented even during turning of the vehicle (S8), or when no slip by a wheel rock occurs during vehicle breaking (S9), running safety of the vehicle is secured, but slip or the like may be caused, so that the movable aerodynamic member is set to a neutral position in which force transmitted to the vehicle approaches to zero.
299 Aerodynamic noise suppressing structure of current collector, lift adjuster of current collector, and karman vortex reducing structure JP2011259072 2011-11-28 JP2013115897A 2013-06-10 KOYO TAKESHI; IKEDA MITSURU
PROBLEM TO BE SOLVED: To provide an aerodynamic noise suppressing structure of a current collector, a lift adjuster of the current collector, and a Karman vortex reducing structure, which lessen the strength of a Karman vortex to reduce aerodynamic sounds from a collector shoe, using a readily attachable and simple structure, and easily adjust a lift acting on the collector shoe.SOLUTION: When a collector shoe 7 moves in an Adirection, ribbons 9a and 9b of a disturbance giving portion 9 are exposed to an airflow F, thus they flutter in the airflow F. As a result, a separation shearing layer on a lower side, from which a Karman vortex Fis generated, interferes with the ribbons 9a. This consequently prevents the growth of the Karman vortex Fgenerated from the separation shearing layer on the lower side to lessen the strength of the Karman vortex F, thereby aerodynamic sounds are suppressed. At the same time, the Karman vortex Fgenerated in a wake of the collector shoe 7 interferes with the ribbons 9b to collapse the Karman vortex F. This reduces the strength of the Karman vortex Fgenerated from the separation shearing layer on the lower side, thereby the aerodynamic sounds are suppressed.

The rotor blade (20) comprises an aerodynamic device (30) for influencing the airflow (61) flowing from the leading edge section (24) of the rotor blade (20) to the trailing edge section (23) of the rotor blade (20). The aerodynamic device (30) is mounted at a surface (28) of the rotor blade (20) and comprises a pneumatic or hydraulic actuator, such as a hose (31) or a cavity (32), of which the volume depends on the pressure of a fluid (62) being present inside the pneumatic or hydraulic actuator. The rotor blade (20) further comprises a control unit (51) for controlling the pressure of the fluid (62) in the hose (31) or the cavity (32) of the aerodynamic device (30). The aerodynamic device (30) is in a first configuration when no pressure application to the fluid (62) in the pneumatic or hydraulic actuator is induced by the control unit (51), and is in a second configuration when the control unit (51) induces the application of a positive or negative pressure to the fluid (62) in the pneumatic or hydraulic actuator. The rotor blade (20) is furthermore characterized in that its lift (71) in the first configuration is smaller than the lift (71) of the rotor blade (20) in the second configuration.
