AERO(HYDRO)DYNAMIC DEVICE Russian patent published in 2001 - IPC

FIELD: automotive industry, shipbuilding, aircraft industry. SUBSTANCE: invention relates to devices aimed at improving aero(hydro)dynamic characteristics of road, water and air vehicles. Device has ejector guide plane installed with clearance behind or in space of main aero(hydro)dynamic surface of vehicle. This plane projects outwards by its ejector part behind main surface at obtuse angle to oncoming flow, other (guide) part of this plane being directed inwards and forwards. Main surfaces can be extended behind rear walls of vehicle, thus forming air or hydraulic pocket with wall. Cheeks for fastening device on vehicle body are installed at end faces of plane. Plane can be hinge-connected to change its angle either by entire plane or by turning ejector part of plane relative to oncoming flow. Proposed device can be provided with aero(hydro)channel with intake and outlet holes on main surfaces. Ejector plane, secured on front edge of outlet hole, projects outwards at obtuse angle to oncoming flow. Guide plane can be secured on rear edge of intake hole and be directed inwards the channel and forwards. Planes can be hinge-connected to main surfaces for changing angle of tilting and overlapping outlet and intake holes, respectively. Common channel can unit many holes with ejector planes. EFFECT: improved performance of vehicles. 9 cl, 10 dwg
