Abstract

Vjetrogenerator s horizontalnim paralelogramom poluga za translatorno gibanje krila koristi se za pretvorbu kinetičke energije vjetra u električnu energiju. Da bi ovaj vjetrogenerator mogao raditi na mnogo većim snagama vjetra, umjesto rotirajućih klasičnih krilnih lopatica, koriste se jedno ili više, simetričnih aerodinamičnih krila postavljenih u vertikalnom položaju. S ovakvim krilima su izbjegnuti veliki otpori u zračnoj struji vjetra, koja dovodi do loma nosivog stupa. Otklonjen je nedostatak geometrijskog izvijanja krilnih lopatica uslijed različitih obodnih brzina duž lopatice, kod kojih se, za zakretni moment, koristila samo tangencijalna komponenta (T) aerodinamične sile (F). Promjenom gibanja krila iz rotirajućeg u translatorno, izbjegnut je otpor vrtloženja, a ostaje samo otpor krila koji je znatno manji. Translatorno gibanje omogućuje horizontalni paralelogram poluga kojeg sačinjavaju: donja radna poluga (6) i kontrolna poluga (8) s nosačem (10) i aktuatorom (11). Paralelogram poluga mijenja prikloni kut (?) između struje zraka i krila (1), te tako koristimo aerodinamičnu silu (F) za gibanje krila u jednu i drugu stranu. Aerodinamična sila se prenosi preko radnih poluga (4) i (6) na radnu osovinu (12) na kojoj je ekscentar (13) s izdankom (17). Izdanak okreće zamašnjak (18) i osovinu (19) s generatorom (21) koji proizvodi električnu energiju. Najefikasnije rješenje je vjetrogenerator s horizontalnim paralelogramom poluga za translatorno gibanje dva krila.A wind turbine with a horizontal parallelogram of levers for translational wing motion is used to convert wind kinetic energy into electricity. In order for this wind generator to be able to operate at much higher wind power, one or more, symmetrical, aerodynamic wings positioned in a vertical position are used instead of rotating conventional wing blades. Such wings have avoided large resistances in the wind's air current, which leads to the breaking of the supporting column. The lack of geometric bending of the wing blades was eliminated due to the different circumferential velocities along the blade, where only the tangential component (T) of the aerodynamic force (F) was used for torque. Changing the movement of the wing from rotary to translational avoids the swirling resistance, leaving only the wing resistance which is much smaller. The translational motion is made possible by a horizontal parallelogram of the levers made up of: the lower operating lever (6) and the control lever (8) with the support (10) and the actuator (11). The lever parallelogram changes the oblique angle (?) Between the air current and the wing (1), so we use the aerodynamic force (F) to move the wing to one side and the other. The aerodynamic force is transmitted through the work levers (4) and (6) to the work shaft (12) on which the eccentric (13) is with the projection (17). The protrusion rotates the flywheel (18) and the shaft (19) with the generator (21) generating electricity. The most effective solution is a wind generator with a horizontal parallelogram of levers for the translational motion of two wings.
