FIELD: defence equipment. SUBSTANCE: control actuator unit has a base accommodating the control actuator, which divides the control actuator cavity into the high-pressure chamber and low-pressure chamber. The high-pressure chamber communicates with the air-intake opening, and the low-pressure chamber communicates with the distribution device and release ducts. The volume of the high-pressure chamber is at least five volumes of the control actuator. To provide the maximum developed moment and increase the speed of response, optimal selection of the relation of the areas of elements through which efflux of the incoming air flow occurs is of an essential importance. The relation between the area of the air-intake opening and the areas of the intake opening in the control actuator made in the form of a gap between the control actuator body and piston, distribution device and release ducts is 1:(0.35-6):(0.35-0.55):(1.8-2.2). EFFECT: provision of the maximum developed moment and enhanced speed of response. |
