Missions for Submarines, Autonomous Underwater Vehicles (AUV) and Autonomous Surface Vessels (ASV) may require transiting the open ocean and conducting over-the-horizon operations in the littoral zone for months. These longer duration missions will demand highly reliable control actuation to ensure mission success, survivability of high value payloads, and to remain undetected.

Electrohydrostatic Actuators (EHA), often referred to as “power by wire”, are fully self-contained actuation systems that combine design elements from electric and electrohydraulic actuation. Moog began investing to develop advanced EHA technology in the late 1980’s for the next generation of “more electric” aircraft flight controls. Over the last two decades, we have matured the technology making significant advancements in performance, reliability, weight and design footprint making it ideal for critical naval subsea and surface missions.

Moog’s presentation will explore the utilisation of EHA technology including:

  • Addressing the demanding requirements of critical naval missions.
  • The various actuation architecture options available for large submarines, AUV and ASV control systems.
  • An evaluation of the advantages and disadvantages of the EHA in the undersea domain relative to naval warfare.
  • An analysis of the relative reliability that can be achieved.
  • The implications of EHA to system redundancy.
