Abstract

Patente de Invenção: <B>"PONTA DE ASA ESPIRAL E CILìNDRICA"<D>. A presente invenção refere-se a um dispositivo na forma de uma cavidade espiral cilíndrica opcionalmente móvel adequada para ser montada na extremidade de qualquer aerofólio de geração de elevação, do tipo de máquina voadora tais como os aviões, os planadores, e os aparelhos que requeiram uma elevação aumentada durante o deslocamento, por exemplo, assim permitindo que um arraste induzido seja reduzido, o empuxo seja aumentado, e permitindo que baixas velocidades em altos ângulos de incidência e altas velocidades em cruzeiro nivelado sejam atingidas em vóo ou enquanto produzindo o levantamento. A aplicação desta invenção torna possível o mesmo desempenho ou o desempenho inicial utilizar motores menos potentes, viajar distâncias mais longas e mais rapidamente enquanto consumindo menos combustível e/ou carregar cargas mais pesadas, e em adição o dispositivo torna possível aumentar consideravelmente e artificialmente a relação de aspecto de uma asa enquanto retendo o mesmo aerofólio e a aerodinâmica inicial de um avião em vóo por exemplo ou de um aparelho de elevação utilizando a elevação para a velocidade subsónica.Invention Patent: <B> "SPIRAL AND CYLINDERIC WING TIP" <D>. The present invention relates to a device in the form of an optionally movable cylindrical spiral cavity suitable to be mounted on the end of any lift generation airfoil, of the type of flying machine such as airplanes, gliders, and devices that require an increased elevation during travel, for example, thus allowing an induced drag to be reduced, the thrust to be increased, and allowing low speeds at high angles of incidence and high speeds on level cruising to be achieved in flight or while producing the lift. The application of this invention makes possible the same performance or initial performance using less powerful engines, traveling longer distances and faster while consuming less fuel and / or carrying heavier loads, and in addition the device makes it possible to increase the ratio considerably and artificially wing aspect while retaining the same aerofoil and the initial aerodynamics of a plane in flight for example or a lifting device using lift for subsonic speed.
