Abstract

Hydro-elastyczna płetwa mieczowa zawiera co najmniej jeden profil (4), podparty co najmniej dwóch dźwigarach (3), a obszar środkowej części profilu (4), pomiędzy dźwigarami (3), charakteryzuje się mniejszą sztywnością od obszarów pomiędzy przednim dźwigarem (3), a krawędzią natarcia oraz pomiędzy tylnym dźwigarem (3) a krawędzią spływu. Profil (4) wykonany jest z materiału sprężystego i może stanowić wypełnienie przekroju poprzecznego płetwy. Obszar profilu (4) pomiędzy dźwigarami (3) wykonany jest z materiału sprężystego o większej elastyczności niż obszary profilu (4) pomiędzy przednim dźwigarem (3) ja krawędzią natarcia oraz pomiędzy tylnym dźwigarem (3) a krawędzią spływu.The hydro-flexible sword fin contains at least one profile (4), supported by at least two girders (3), and the area of the central part of the profile (4), between the girders (3), is characterized by lower rigidity than the areas between the front girder (3) , and the leading edge and between the rear girder (3) and the trailing edge. The profile (4) is made of elastic material and can be used to fill the fin's cross-section. The profile area (4) between the beams (3) is made of elastic material with greater flexibility than the profile areas (4) between the front girder (3) and the leading edge and between the rear girder (3) and the trailing edge.
