FIELD: machine building.
SUBSTANCE: two-channel fuel supply and control system of the GTE relates to the field of aircraft engine building and is designed to automatically control the GTE in all engine operating modes. System contains the main and backup control channels, an inter-throttling chamber, adjustable chokes, a constant pressure valve on the metering unit, and a pneumo-hydraulic converter.
EFFECT: improvement of the dynamic characteristics of the GTE with the backup control channel in all operating conditions is achieved due to the fact that in the backbone of the backup control channel, connected to the controlled cavity of the servomotor of the dispenser, a spool with a variable flow section is installed, hydraulically connected to the pneumo-hydraulic converter.
