Цель изобретения - снижение уровня аэродинамического шума.The purpose of the invention is to reduce the level of aerodynamic noise.
На чертеже приведена головка, осевой разрез.The drawing shows the head, the axial section.
Вентиляционная головка содержит корпус 1 в виде усечёаЫрго конуса, тарелку 2, шпиндель 3 с маховиком 4 и крестовину 5. При’этом отношение расстояния Ь от крестовины 5 до боль2The ventilating head contains a housing 1 in the form of a truncated cone, a plate 2, a spindle 3 with a flywheel 4 and a crosspiece 5. At the same time, the ratio of the distance L from the crosspiece 5 to the pain 2
