FIELD: physics, control.
SUBSTANCE: system for controlling two variable geometry devices in a turbo machine comprises an actuating mechanism which acts on both variable geometry devices. One of the variable geometry devices is a blade device having a stator blade step with a variable setting angle. The other variable geometry device is a valve device which is an air bleeder valve. The blade device is part of the high-pressure housing of a turbo machine and the valve device is part of the low-pressure housing of a turbo machine. The control system is configured to control by gradually opening the blade step and gradually closing the air bleeder valve as the value of the actuating mechanism control parameter increases. Another invention of the group relates to a turbo machine having said control system.
EFFECT: group of inventions reduces the weight and size of the system for controlling two variable geometry devices.
