FIELD: engines and pumps.
SUBSTANCE: invention may be used in electronic hydromechanical systems (ACS) of automatic control of a gas turbine engine (GTE). In addition to the first EMC there is the second and third EMCs introduced, besides, the second hydraulic inlet of the first EMC is connected with the outlet of the second EMC, in which the first hydraulic inlet is connected with the low pressure manifold, and the second hydraulic inlet - with the outlet of the third EMC, the first hydraulic inlet of which is connected with the low pressure manifold, and the second one - with the high pressure manifold, the controlled inlet of the second EMC is connected via diode isolation with the third outlet of the electronic controller and a tumbler "Stop" in the cabin of the aircraft, the controlled inlet of the third EMC - with a tumbler "Stop" in the aircraft cabin.
EFFECT: improved quality of ACS operation and higher reliability of GTE and safety of AC due to introduction of redundancy of unreliable elements in a tract of fuel supply to CC.
