Evaluation Of Modifications Designed To Boost Performance Underway

AgustaWestland is flight testing a number of aerodynamic improvements that will boost the performance of the AW609 TiltRotor. The company undertook the first flight of a modified vertical tail fin on AW609 TiltRotor prototype #2 at its Cascina Costa flight test facility in Italy July 25. The modified vertical fin is one part of an extensive package of product improvements which also include a new, more aerodynamic, design for the engine exhaust nozzles and changes to the prop-rotor spinner cones. Together, these modifications reduce the drag factor of the AW609 TiltRotor by approximately ten percent, as well as delivering a significant weight reduction, with a resulting performance increase.

“These aerodynamic improvements, new avionics, new cockpit display system and a large number of other improvements will together give the aircraft greater performance and mission capabilities, making it even more attractive for carrying out a wide range of missions which can benefit from its much higher cruise speed, high altitude cruise capability and longer range, when compared to existing helicopters or other proposed high speed rotorcraft,” said Clive Scott, AW609 Program Manager.

An upgraded version of the Pratt & Whitney Canada PT6 engine is being used on the AW609 TiltRotor and will include the latest in technological developments, providing the aircraft with increased performance capabilities as well as the latest safety enhancements.

Rockwell Collins is supplying a fully integrated cockpit for the AW609 TiltRotor based on its Pro Line Fusion system, allowing AgustaWestland to adopt the very latest in commercial aircraft cockpit technologies, including 14 inch touch screen displays, integrated flight management systems with satellite based navigation, synthetic and enhanced vision systems and Head-Up-Display interfaces; all of which will be integrated with the aircraft’s own avionics management systems. This cockpit suite will provide the crew with increased situational awareness and will reduce pilot workload.

BAE Systems is providing an upgraded Flight Control Computer at the heart of the AW609 TiltRotor’s triple redundant fully digital fly-by-wire flight control system. The computer will include not only the AgustaWestland control laws and flight control software but also the digital engine control system.

These modifications are an integral part of the overall AW609 TiltRotor program re-baselining aimed at reducing customer acquisition and operating costs, coupled with delivering performance and technology improvements.
