Engine Control Variable Stator Valve Actuator

The engine control variable stator vane actuator controls the position of the compressor stator vanes.

Overview

The engine control variable stator vane actuator is a linear actuator, with an integral two-stage, four-way electrohydraulic servo valve for control and position sensing for engine control feedback. Inputs to the engine control variable stator vane actuator are torque motor direct current, position feedback excitation voltage and regulated fuel pressure. The engine control variable stator vane actuator outputs are in the form of piston stroke and position feedback voltages.

Additional details include:

Controls position of compressor stator vanes
Provides positional feedback to engine controller
Driven by pressurized fuel or air (pneumatic)
Increases engine efficiency especially in higher pressure ratio engines
Engine case mounted
Integrated electrical components capable of highest temperatures in industry
Actuator has fire-resistant and fire-proof options
Lowest weight options of any supplier through robust design technology
Proven pedigree from large and small propulsion engine and auxiliary power engine operability components

We also offer electromechanical product options.
