Abstract
Изобретение позвол ет повысить КПД вентил тора. Отношение длин дуг 5 участков 3 и 4, образованных пересечением поверхности каждого участка.с цилиндрическими поверхност ми, ось которых расположена на оси вращени рабочего колеса, подлине разреза 2 посто нно. Такое выполнение разреза лопатки обеспечивает более равномерное обтекание пера 1 лопатки, что приводит к снижению аэродинамических потерь. 2 ил,The invention allows to increase the efficiency of the fan. The ratio of the lengths of the arcs of 5 sections 3 and 4, formed by the intersection of the surface of each section. With cylindrical surfaces, the axis of which is located on the axis of rotation of the impeller, is half of section 2 constant. This embodiment of the incision of the blade provides a more uniform flow around the blade 1 of the blade, which leads to a decrease in aerodynamic losses. 2 or
