Abstrakty
W niniejszym artykule przedstawiono ideę i wstępne obliczenia dotyczące małego samolotu bezzałogowego z zaimplementowanymi barierami mechanicznymi przy krawędziach natarcia. Pokrótce opisano prace prowadzone na całym świecie nad tego typu zagadnieniem. Na drodze obliczeń numerycznych wyznaczono rozkłady ciśnienia powietrza na powierzchniach nośnych płatowca typu delta. Wyznaczono wartości sił i współczynników aerodynamicznych. Porównano wyniki obliczeń przeprowadzone dla obiektu bez barier z wynikami uzyskanymi dla obiektu z zamontowanymi w barierami. Wyznaczone położenie i wymiary mechanicznych turbulizatorów powinny zapewnić możliwie największe zmiany wartości sił aerodynamicznych. Obliczenia przeprowadzono z myślą o wykorzystaniu barier mechanicznych do sterowania lotem mikrosamolotu.
In this paper the idea of micro UAV and preliminary calculations with mechanical barriers implemented near edges of attack were presented. The world-wide investigations on such a problem were shortly described. Air pressure distribution on plane lift surfaces was obtained by means of numerical calculations. Aerodynamics forces and coefficients values were determined. Results of calculations conducted for delta wing without barriers were compared with those obtained for plane with mechanical edge turbulizers. The obtained position and dimensions of the barriers should ensure the best possible aerodynamic forces values modifications. The calculations were conducted with a view to taking advantage of edge mechanical barriers in order to control the MAV flights.
