The invention relates to aviation equipment. An object of this invention is to develop a new aerodynamic device which can extend the range of aerodynamic devices for aviation, increase the efficiency of the air flow power use, increase the efficiency of the lifting force and improve the efficiency of controlling the wing resultant forces. For this purpose, the aerodynamic device has an aerodynamic wing (2) with a blower (1) of gaseous working fluid (such as air) mounted above the wing (2), in accordance with the invention, the aerodynamic wing (2) has a specific shape it is designed in the form of a double-curved open surface made up by a system of longitudinal grooves (7,8) along the whole wing surface The wing (2) has a convergent segment (4) and a divergent segment (6); between the convergent and the divergent segments there is a smooth transitional segment (5). The wing outlines have end elements (11). In the convergent and the divergent segments of the wing lower surface which is not blown by air, there is a controlled drive system (10) for the wing surface cambering and area changing. The divergent segment tip on the wing trailing edge has a deflectable controlled element (9). The structural parts of the present invention meet special conditions.

The system comprises a main wing (3) with deflected flap (5), a blowing arrangement (1) with a number of nozzles located in front of the deflected flap (5) along the trailing edge of the main wing (3), static pressure sensors (4) fastened to the deflected flap (5), flight sensors (7) for measuring aircraft flight parameters, activating device for activating the blowing arrangement (1), and a control unit (6) connected to the sensors and activating device. The each nozzle is in the form of triple mini nozzle (2) with one inlet channel (10), streamlined collection chamber (9) and three outlet channels (11). wherein the outlet openings of the outlet channels (11) are located on the trailing edge of the main wing (3) above the axis of rotation of the flap (5) and the static pressure sensors (4) are located on the upper surface of the deflected flap (5), close to the flap trailing edge.
摘要:
A flow control actuator (10) for a body exposed to fluid flow comprises first and second flow surfaces (14, 16) spaced to define an elongate gap (20) therebetween. An elongate control element is disposed in or adjacent the gap and has an externally facing arcuate surface and defines a first slot (24) between the control element and said first flow surface and a second slot between said control element and said second flow surface (26). The control element (22) is moveable to allow the width of said slots to be adjusted generally proportionally. The flow of pressurised flow control fluid passes from a plenum chamber (30) out through one or both slots (24, 26) to be deflected around the arcuate surface under the influence of the Coanda effect. The flow control actuator (10) may be provided in the trailing or leading edge of an aerofoil; alternatively it may be provided between two surfaces spaced to provide said gap but otherwise providing a generally continuous surface.
