Development, design and manufacturing of a micro electromechanical actuator for aeronautical applications tested and flight qualified.

The lightness and compactness of the resulting actuator, allows integrating them inside the wing / flap boxes, avoiding thus extra fairing. It has a high power density: 120 W. of peak power within 60x90x150 mm dimensions.

EMA Health Monitoring System:

  • SENER’s Health Monitoring and Management System for EMAs monitors different operating parameters of the actuator in real time.
  • It provides failure detection, diagnostic, and prognostic information to the platform and its maintenance operators.
  • Proactive maintenance strategies make use of the data in order to repair or replace the EMA before failure.
  • Main features:
  • Application: Secondary Flight Control
  • Output movement: linear
  • Motion transformation: Roller screw
  • Actuator mass: 2.1 Kg
  • Temperature range: -65ºC / +70ºC
