Abstract

Przedmiotem zgłoszenia jest aerodynamiczny kolektor wydechowy, zwłaszcza do tłokowych silników lotniczych, który charakteryzuje się tym, że w wewnętrznej części profilowanej (1) kolektora wydechowego od strony wlotu gazów spalinowych (2) zamocowana jest podpora czołowa (3), a od strony wylotu gazów spalinowych (4) zamocowana jest podpora tylna (5). Pomiędzy podporą czołową (3), a podporą tylną (5) umieszczony jest co najmniej jeden obrotowy rotor (6). Obrotowy rotor (6) składa się z co najmniej dwóch kierownic gazów (7) o zarysie śrubowym o stałym skoku i zmiennej szerokości geometrycznej zamocowanych na wale (8). Wał (8) łożyskowany jest w łożysku (9a) osadzonym w podporze czołowej (3) i w łożysku (9b) osadzonym w podporze tylnej (5). Kąt osi obrotu wału (8) obrotowego rotora (6) względem osi wzdłużnej kolektora wydechowego wynosi od 0° do 30°.The subject of the application is an aerodynamic exhaust manifold, especially for piston aircraft engines, which is characterized in that in the internal profiled part (1) of the exhaust manifold, from the side of the exhaust gas inlet (2), a front support (3) is mounted, and from the side of the exhaust gas outlet (4) the rear support (5) is attached. At least one rotary rotor (6) is placed between the front support (3) and the rear support (5). The rotating rotor (6) consists of at least two gas guides (7) with a helical profile with a constant pitch and variable geometric width mounted on the shaft (8). The shaft (8) is mounted in a bearing (9a) mounted in the front support (3) and in a bearing (9b) mounted in the rear support (5). The angle of the axis of rotation of the shaft (8) of the rotary rotor (6) in relation to the longitudinal axis of the exhaust manifold ranges from 0° to 30°.
