Electric servo-actuator CSDEHA001

electrohydrostaticEHAnot specified

Overview
Parker Aerospace designs and manufactures electrohydrostatic actuation (EHA) systems that use electric power for aircraft flight-control surface actuation. These self-contained, motor-driven units replace centralized hydraulic systems to reduce aircraft weight, improve power efficiency and simplify maintenance. EHA solutions are developed for both primary and secondary control surfaces and are engineered to meet aerospace qualification standards.

Key features

• Electrohydrostatic Actuation (EHA) system architecture with integrated motor, pump and local reservoir
• Electric-power driven actuation for primary and secondary flight-control surfaces
• Lower aircraft weight compared with conventional centralized hydraulic systems
• Improved power efficiency and localized power management
• Enhanced maintainability and modular serviceability
• Designed and manufactured by Parker Aerospace

Applications

• Actuation of aircraft flight-control surfaces (elevators, ailerons, rudders, flaps)
• Suitable for tail surfaces and other primary/secondary control surfaces on commercial, military and rotorcraft platforms
