Rudder Bias Actuation System
Product catalog summary
Overview: The document provides technical specifications for the Rudder Bias Actuation System developed by FIMAC S.p.A., designed for use in business jet planes, specifically the Learjet LJ85. This system is crucial for providing additional yaw control in the event of an engine failure.
Specifications:
- Operating Temperature: -55°C to +85°C
- Operating Fluid: Engine Air at 149°C
- Operating Low Pressure: 65 psi (4.7 bar)
- Unit Weight: 4.0 kg
- Stroke: 88 mm
- Operating Voltage: 28 Vdc
- Piston Speed: 0.05 m/sec
- Piston Load (Extension): 900 N
- Operating High Pressure: 300 psi (20.7 bar)
Functionality: The Rudder Bias Actuator is a pneumatic device that enhances yaw control by using low-pressure bleed air from each engine, regulated by spool and sleeve valves, to maintain balance at its neutral position.
Application: This actuator is specifically employed on the Learjet LJ85, providing critical support in maintaining control during engine failure scenarios.

^—Rudder Bias Actuation System The Rudder Bias Actuator is a pneumatic actuator installed on the rudder control system of a business jet plane. In the event of an engine failure, the rudder bias actuators provide additional yaw control power to alleviate pilot effort. Each actuator is balanced at its neutral position using low pressure bleed air from each engine regulated by spool and sleeve valves. Operating Temperature:
