摘要： The invention is related to an aerodynamic blunt aft body (10) of a helicopter fuselage with two strakes (7, 8) along an aft surface (9) and/or respective left hand and right hand side fuselage surfaces (5, 6). Each strake (7, 8) is defined by first and second intersection lines (3, 4) resulting from intersections of horizontal planes (z) with the surface of the aft surface (9) or the respective left hand and right hand side fuselage surfaces (7, 8). The strakes are defined by a two or three dimensional spline (12) from the surface (2) towards the aft surface (9) inside said first and second intersection lines (3, 4) and inside the bounding box (15).

摘要： A displacement amplifier receives an actuation displacement signal from a piezoelectric actuator. The displacement signal is amplified by one or more stages of compliant elements, and a corresponding force is applied to a load. Wide frequency response is achieved in response to the resilience characteristics of the compliant elements that are formed from any of several materials, illustratively aluminum, steel, titanium, plastics, composites, etc., and are produced by any of several manufacturing techniques, illustratively extrusion, die casting, forging, etc. The compliant elements can be configured as plural compliant mechanical displacement amplifier stages. In bilateral arrangements displacement signals from distal ends of the motive source are applied to symmetrical, or mirror image, arrangements of compliant elements. The motive source, which may be a piezoelectric actuator, delivers its displacement signal at one end thereof to one or more compliant elements. The other end of the piezoelectric actuator can be grounded.

摘要： To delay, reduce or prevent laminar and/or turbulent boundary layer separation a plurality of spaced-apart vortex generators (10a, 10b) have a plasma actuator (22) distributed amongst them. The plasma actuator (22) includes a first electrode (24) carried by the first vortex generator (10a), and a second electrode (26) carried by the second vortex generator (10b) in a location downstream of the first electrode, both electrodes being preferably carried by the inboard surfaces of the respective vortex generators. In other embodiments additional electrodes may be provided in the respective vortex generators (10a, 10b) and/or in a body surface on which the vortex generators are disposed. The plasma actuator (22) is configured to generate an electric field between the vortex generators (10a, 10b) and to induce fluid flow from one of the vortex generators to another of the vortex generators across a space between them. The plasma actuator is typically an AC dielectric barrier discharge device or a DC ion wind device.

摘要： The invention relates to an aero- or hydrodynamic construction, which is arranged to be in relative motion with respect to a medium, the construction comprising a front end (2) where the medium is encountered and a rear end (3) where the medium exits the construction, the construction comprising an aerofoil (10) with an end (14) for encountering the medium and an end (15) for leaving the medium. In order to keep undesired energy losses caused by the construction when it moves with respect to the medium very small, in which case it would operate with high efficiency and have a low noise level, the construction is characterized in that the aerofoil comprises a ridge part (4) and a valley part (5), which constitute a flow channel which is set at an angle (α) to the direction of motion of the construction in order to remove the medium in the form of tubular turbulent flow, a micro-vortex, from the rear end of the construction, the turbulent flow being substantially opposite to the direction of motion of the construction.
