we service
At the heart of aircraft engine performance and reliability, our teams support the
maintenance of a wide range of advanced equipment families
Oil system components
The oil system is a critical part of the engine. In particular, the lubrication unit ensures efficient lubrication and cooling of mechanical components, enabling high rotational speeds while maintaining reliability and long service life.
Valves
High- and low-pressure (HP/LP) valves of the Active Clearance Control (ACC) system optimize engine performance by precisely adjusting internal clearances throughout each phase of operation.
Fuel System Components
On board the aircraft, fuel is not only used to produce thrust: pressurized by the fuel pump, it also powers several engine actuators, including those of the VBV and VSV systems.
Sensors
Sensors installed on turbofan engines continuously measure key physical parameters (speed, vibrations, temperature, fluid levels, etc.) to provide an accurate, real-time view of the engine’s condition.
