Engine Control Actuation

Honeywell engine control actuators drive some of the world’s most modern variable geometry control needs.

Our weight-efficient and affordable solutions are based on decades of fueldraulic, pneumatic and electromechanical applications on commercial, military and business jet platforms. Our products adjust the position of valves to control bleed air transmission, and the position of compressor stator vanes to control air massflow and angle.


The Variable Bleed Valve Actuator is a pneumatic, fuel-driven or electromechanical actuator which adjusts the position of engine bleed valves and provides feedback to the engine’s controller. This increases engine efficiency, especially in higher pressure ratio engines and is available in fire-resistant and fire proof versions. Through robust design technology, Honeywell has a proven pedigree offering the lowest weight option, capable of persisting the highest temperatures in the industry. Among others, this includes the CFM56-5B and LeapX-1B turbofan engines.


Hydraulically/Fueldraulically driven Guide Vane Actuators which position the compressor guide vanes as scheduled by the FADEC or ECU in conjunction with the Main Fuel Control. The actuator consists of a hydraulic driven piston, load carrying rod end bearing and an Electrohydraulic Servovalve (EHSV) and a resolver for feedback and loop closure.


Over 10,000 Exhaust Nozzle Control Systems delivered since 1974. This mechanical system is driven by an air motor powered by engine compressor discharge air. The air motor drives five ball screw actuators through flexible drive cables. Control of the air motor is typically accomplished by a hydraulic servo signal, scheduled by the fuel control or can be controlled directly by the FADEC. This is a highly responsive system, with the air motor attaining 25,000 rpm during transients in order to meet the 0-to-100 percent per second slew requirements. The Air motor can be replaced with an Electric motor to drive the ball screws through the flexible drive cable.
