BAE Systems, ROCHESTER: As part of its Helicopter Electro Actuation Technology (HEAT) program for the U.K. Royal Navy's EH101 Merlin helicopter fleet, AgustaWestland has awarded a GBP 18.5 million ($32 million U.S.) contract to BAE Systems for the development of the digital flight control computer. HEAT will be the first electromechanical fly-by-wire system installed on a helicopter.
“The new state-of-the-art system will replace older, more complex hydraulic systems,” said Mike Austill, managing director of Avionic Systems for BAE Systems. “This reduces pilot workload, cost of ownership, maintenance, and weight while improving survivability, safety, and aircraft handling and agility.”
The HEAT system, designed in a joint effort by AgustaWestland, BAE Systems, and Claverham, will replace the existing hydro-mechanical rotor control system on the EH101. It comprises two dual-lane flight control computers that together will provide quadruple-redundant electronic control — allowing the system to function safely even if two of the systems were to fail. The fly-by-wire controls initially will interface with the pilot inceptors and actuators, and eventually will replace the existing autostabilizer and autopilot functionality.
“We are pleased to partner with BAE Systems on this groundbreaking technology, and we look forward to benefiting from the company's decades of fly-by-wire experience,” said Martin Fausset, programs director at AgustaWestland.
The system will expand the operational envelope of the aircraft for U.K. Royal Navy ship operations in adverse weather. It also will improve aircraft handling, enabling improved terrain following and masking and increased agility on the battlefield. The very high reliability and low power dissipation of the HEAT flight control system will ensure the Merlin's ability to operate for long periods remote from landing bases.
BAE Systems is the premier trans-Atlantic defense and aerospace company, delivering a full range of products and services for air, land and naval forces, as well as advanced electronics, information technology solutions and customer support services. BAE Systems, with more than 100,000 employees worldwide, had 2005 sales that exceeded GBP 15.4 billion (U.S. $28 billion).
