Abstract

Изобретение позвол ет снизить аэродинамический шум вентил тора. Осевой зазор между отсекателем 5 и торцовой поверхностью 6 рабочего колеса 3 составл ет 0,01 - 0,08 его внутреннего радиуса. Такое выполнение позвол ет уменьшить взаимодействие отсекател  с пограничным слоем, возникающим на торцовой поверхности, и улучшить дросселирование потока через зазор . 2 ил.The invention makes it possible to reduce the aerodynamic noise of a fan. The axial clearance between the cutter 5 and the end surface 6 of the impeller 3 is 0.01-0.08 of its internal radius. This embodiment allows to reduce the interaction of the trimmer with the boundary layer that occurs on the end surface and to improve the throttling of the flow through the gap. 2 Il.
