Description

Oblast technikyTechnical field

Technické řešení se týká aerodynamického profilu křídla, zejména v konstrukci letounu, konkrétně v geometrii křídla, přičemž ovlivňuje jeho aerodynamické charakteristiky. Geometrie křídla je dána tvarem aerodynamického profilu v jednotlivých řezech.The technical solution relates to the aerodynamic profile of the wing, in particular in the design of the airplane, in particular in the geometry of the wing, while influencing its aerodynamic characteristics. The geometry of the wing is determined by the shape of the aerodynamic profile in the individual sections.

Obecně známé profily, dané jistou geometrií a jí odpovídajícími aerodynamickými charakteristikami, nejsou vhodné pro každé letadlo, které je navrhováno. Zejména složitý geometrický tvar může působit technologické obtíže při výrobě. Křídla pro speciální účely jsou popsána například ve spisech CZUV 17179, CZUV 15912, CZUV 18600.Generally known profiles, given a certain geometry and corresponding aerodynamic characteristics, are not suitable for each aircraft being designed. In particular, the complex geometric shape can cause technological difficulties in production. The special purpose wings are described, for example, in CZUV 17179, CZUV 15912, CZUV 18600.

Podstata technického řešeniThe essence of the technical solution

Výše uvedené nedostatky stávajících řešení jsou do značné míry odstraněny aerodynamickým profilem křídla podle tohoto technického řešení. Jeho podstatou je to, že jeho spodní strana je na 29 až 100 % hloubky ve tvaru rovinné plochy a geometrický tvar aerodynamického profilu je definován následujícími souřadnicemi v Tab. 1:The above-mentioned shortcomings of the existing solutions are largely eliminated by the aerodynamic profile of the wing according to this technical solution. Its essence is that its underside is 29 to 100% of the depth in the shape of a planar surface and the geometric shape of the aerodynamic profile is defined by the following coordinates in Tab. 1:

- 1 CZ 21448 Ul kde je x- souřadnice bodu profilu ve směru jeho hloubky a y- souřadnice bodu profilu ve směru jeho tloušťky.Where the x-coordinate of the profile point is in the direction of its depth and the y-coordinate of the profile point is in the direction of its thickness.

Podstata tohoto technického řešení je dána geometrickým tvarem profilu, kterému odpovídají jisté aerodynamické charakteristiky. Z nového tvaru profilu plynou i nové aerodynamické cha5 rakteristiky. Značnou výhodou tohoto profilu je to, že jeho spodní strana je ve tvaru rovinné plochy, to znamená, že jeho spodní strana je rovná. Toto řešení zvyšuje jeho využitelnost např. při amatérské stavbě letounu a představuje značné technologické zjednodušeni při výrobě křídla. Oproti jiným podobným profilům je zvýšen maximální součinitel vztlaku, což umožňuje použití menšího křídla na letounu a tím jisté úspory při jeho stavbě.The essence of this technical solution is given by the geometric shape of the profile, which corresponds to certain aerodynamic characteristics. The new profile shape also results in new aerodynamic characteristics. A considerable advantage of this profile is that its underside is in the form of a planar surface, i.e. its underside is straight. This solution increases its usability eg in the amateur construction of aircraft and represents a significant technological simplification in the production of the wing. Compared to other similar profiles, the maximum buoyancy coefficient is increased, which allows the use of a smaller wing on the aircraft and thus some savings in its construction.
