ELECTROHYDROSTATIC ACTUATION

Parker Aerospace designs and manufactures electrohydrostatic actuation (EHA) and electrical backup hydraulic actuation (EBHA) systems that eliminate the need for central hydraulics.  EHA systems are power-by-wire actuation systems that utilize aircraft electric power for flight control surface actuation.  These systems are highly energy efficient and provide an overall weight benefit to the aircraft.

EHAs and EBHAs can be used anywhere traditional hydraulic actuation is needed.  Today EHAs and EBHAs are used on:

  • Commercial transports
  • Military fighters
  • Business jets

Technical highlights

Our EHAs offer significant advantages such as:

  • Reduced power consumption
  • Reduced vulnerability
  • Reduced life-cycle costs
  • Reduced system weight
  • Improved power consumption
  • High-pressure range
  • Voltage range
