Doterajší stav technikyCurrent state of the art
Lietadlá vyrábané a používané v súčasnosti majú často na konci krídiel koncové aerodynamické krídelká (Winglety). Sú to malé pomocné plochy rôzneho tvaru na konci nosného krídla lietadla. Usmerňujú vzdušné víry, ktoré pôsobia na konce krídiel. Dôsledkom toho je znížený indukovaný odpor krídiel počas letu, čo spôsobuje zníženú spotrebu paliva a tým aj väčší dolet. Aerodynamické krídelká môžu mať taktiež vplyv na vlastnosti lietadla počas vzletu, dokážu zlepšiť jeho riaditeľnosť a znížiť hlučnosť stroja. V súčasnosti je u novších lietadiel bežná montáž aerodynamických krídiel na krídlach. Aj napriek tomu, že aerodynamické krídelká minimalizujú turbulencie na koncoch krídiel, ich zvolené tvary obvykle len málo odbiehajú od rozmerov (hlavne šírky) krídiel, čo nekorešponduje úplne s krídlami pozorovanými v prírode, ktoré majú induktívny odpor krídiel potlačený oveľa efektívnejšie. Problematika aplikácie aerodynamických krídiel je uvedená napríklad v nasledujúcej literatúre a v patentových listinách:Airplanes manufactured and used today often have winglets at the end of their wings. They are small auxiliary surfaces of various shapes at the end of the aircraft wing. They direct the air vortices that act on the ends of the wings. The consequence of this is reduced induced wing drag during flight, which causes reduced fuel consumption and thus greater range. Aerodynamic wings can also have an effect on the properties of the aircraft during take-off, they can improve its controllability and reduce the noise level of the machine. Nowadays, it is common for newer aircraft to mount aerodynamic wings on the wings. Despite the fact that aerodynamic ailerons minimize turbulence at the ends of the wings, their chosen shapes usually only slightly deviate from the dimensions (mainly the width) of the wings, which does not completely correspond to the wings observed in nature, which have the inductive resistance of the wings suppressed much more effectively. The issue of the application of aerodynamic wings is presented, for example, in the following literature and in patent documents:

Podstata vynálezuThe essence of the invention
Podstata vynálezu spočíva v uplatnení riešenia dvojrozmerne zahnutých aerodynamických krídelkách na krídle lietadla. Tieto majú pôdorys vo forme oblúkovo zahnutej trojuholníkovej plochy smerom dozadu a súčasne je táto plocha zahnutá nahor vo forme spojitého oblúka. Riešenie umožňuje zníženie indukovaného odporu krídiel počas letu lietadla a zníženie indukovaného odporu oproti krídlam s bežným typom aerodynamických krídeliek. Výsledkom je zvýšenie úžitkových, prevádzkových a letových vlastností celého stroja pri pomerne neveľkom investičnom vklade.The essence of the invention consists in the application of the solution of two-dimensional curved aerodynamic wings on the wing of the aircraft. These have a floor plan in the form of an arched triangular surface towards the back, and at the same time this surface is curved upwards in the form of a continuous arch. The solution makes it possible to reduce the induced resistance of the wings during the flight of the aircraft and to reduce the induced resistance compared to wings with a conventional type of aerodynamic wings. The result is an increase in the utility, operational and flight characteristics of the entire machine with a relatively small investment.

Na obr. 1 je znázornený príklad uskutočnenia vynálezu. Znázorňuje celkové usporiadanie funkčných častí navrhovaného mechanizmu. Vynález pozostáva z lietadla (1) s krídlami (2), ktoré sú vybavené aerodynamickými krídelkami (3) a ktoré majú pôdorys vo forme oblúkovo zahnutej trojuholníkovej plochy smerom dozadu a súčasne je táto plocha zahnutá nahor vo forme spojitého oblúka.In fig. 1 shows an example of an embodiment of the invention. It shows the overall arrangement of the functional parts of the proposed mechanism. The invention consists of an aircraft (1) with wings (2), which are equipped with aerodynamic wings (3) and which have a floor plan in the form of an arched triangular surface towards the rear, and at the same time this surface is curved upwards in the form of a continuous arc.
Výhodou vynálezu je ďalšie zníženie celkového indukovaného odporu lietadla (1) o zníženie indukovaného aerodynamického odporu krídiel (2) počas letu, čo spôsobí ďalšie zníženie spotreby paliva a tým aj zväčšenie doletu. Aerodynamické krídelká (3) zväčšia ich vplyv na vlastnosti lietadla (1) počas vzletu, dokážu zlepšiť jeho riaditeľnosť, znížiť hlučnosť stroja a skracujú jeho rozbeh pri štarte. Potlačia turbulencie na koncoch aerodynamických krídeliek (3) a tým zmenšia pravdepodobnosť prípadného vzniku kmitov krídiel (2).The advantage of the invention is a further reduction of the total induced resistance of the aircraft (1) by a reduction of the induced aerodynamic resistance of the wings (2) during flight, which causes a further reduction in fuel consumption and thus an increase in range. Aerodynamic wings (3) increase their influence on the characteristics of the aircraft (1) during take-off, can improve its controllability, reduce the noise of the machine and shorten its run-up at take-off. They suppress the turbulence at the ends of the aerodynamic wings (3) and thereby reduce the probability of possible wing oscillations (2).
