Abstract
Изобретение относитс к конструкци м рабочих колес турбомашин. Выходные кромки 4 через одну наклонены к несущему диску 3, а остальные к покрывному диску 2. За счет такого выполнени происходит расфазировка элементарных источников шума на выходе из колеса. В результате снижаетс уровень аэродинамического шума, повышаютс устойчивость и надежность работы. Выходные кромки 4 могут быть выполнены в виде нескольких зубьев с наклонными гран ми. 1 з.п. ф-лы, 3 ил.This invention relates to turbomachine impeller designs. The output edges 4 are tilted to the carrier disk 3 through one, and the rest to the covering disk 2. Due to this arrangement, skewing of the elementary noise sources at the wheel outlet occurs. As a result, the level of aerodynamic noise is reduced, and stability and reliability are improved. The exit edges 4 can be made in the form of several teeth with inclined edges. 1 hp f-ly, 3 ill.
