EHA/EBHA innovation

Electrohydrostatic actuation (EHA) and electric backup hydraulic actuation (EBHA) are power-by-wire systems that deliver less system weight, enhanced avionics integration, and reduced lifecycle costs. EHAs and EBHAs are self-contained hydraulic systems controlled by high-power electronics which allow the use of traditional, proven hydraulic actuation configurations for fault tolerance.

Efficient flight-proven system expertise

The product of decades of research, development, and flight-tested reliability, Parker EHAs and EBHAs offer significant advantages:

  • Reduced system weight - Hydraulic distribution systems are reduced
  • Reduced power consumption - Power is used as required, yielding a more efficient system
  • Improved maintainability - Hydraulic disconnections between actuation equipment and the vehicle system are eliminated
