System for controlling variable geometry equipment of a gas turbine engine particularly comprising a barrel link

摘要

A system for controlling at least two variable geometry apparatuses of a gas turbine engine that includes at least a first body and a second body, the first apparatus including a stator blade stage with a variable setting angle of a compressor of the first body capable of switching between a closed position in an idle mode and an open position in a high-speed mode, and the second apparatus including at least one discharge valve of a compressor of the second body capable of switching between an open position in an idle mode and a closed position in a high-speed mode. The system further includes an actuator for actuating the two apparatuses.

1. A system for controlling at least two variable geometry equipment items of a gas turbine engine, the engine including at least a first body rotating at a first speed and a second body rotating at a second speed, the first equipment item being a variable-angle stator vane stage of a compressor of the first body moving between a closed position when idling and an open position at high speed, the second equipment item being at least one discharge valve of a compressor of the second body moving between an open position when idling and a closed position at high speed, the system comprising:
an actuator that actuates the first and second equipment items, wherein the actuator controls a rod on which is mounted a barrel control member, the barrel control member driving one of the first and second equipment items and being linked to the rod by a link via which it is driven, the link comprising a pin that is mobile in a guiding track, a profile of the guiding track determining at least one actuation law for the one equipment item according to displacement of the rod of the actuator.
