Original abstract

The present article deals with investigation of possible causes of the additional torque on the yacht’s rudder. One of the most important aspect for design of yachts are the symmetric conditions of all parts, which are located under water level and concentricity of the ship’s screw, rudder and keel relative to the hull. These symmetric and concentricity conditions have a major impact on the resulting dynamic properties of the ships. They have either substantial impact on the overall efficiency of installed engine and ship’s screw. As the result of poorly designed above mentioned parts, there can be an unsolicited additional torque on the yacht’s rudder and higher consumption of the fuel. Last but not least of these problems leads to poor controllability and discomfort within steering. This article is focused on the investigation of possible causes of the additional torque on the yacht’s rudder.

Czech abstract

Tento článek se zabývá vyšetřování možných příčin přídavného momentu na kormidle jachty. Jedním z nejdůležitějších aspektů při konstrukci jachet je symetrie všech částí, které jsou umístěny pod hladinoujsou a souosost lodního šroubu, ormidla a kýlu vzhledem k trupu lodi. Tyto podmínky symetrie a soustřednosti mají významný vliv na výsledné dynamické vlastnosti lodí. Mají dopad na celkovou účinnost instalovaného motoru a lodního šroubu. Důsledem nepřesné výroby výše uvedených komponent může být přídavný moment na kormidle jachty a vyšší spotřeba paliva. Současně s tím dochází ke špatné ovladatelnosti lodi a nepohodlí při řízení lodi. Tento článek je zaměřen na zkoumání možných příčin přídavného momentu na kormidle jachty.
