In June this year the second multi-year procurement contract was signed for the Bell Boeing V-22 Osprey. It will deliver 93 MV-22s for the Marine Corps and seven more CV-22s for the US Air Force over the course of five years. With the current annual rate of production running at around 40 aircraft, that means that in the near future there will be considerable production capacity available for foreign military sales (FMS) as deliveries to the U.S. military drop off.
Israel will receive six Bell-Boeing V-22 Osprey tiltrotors, U.S. Secretary of Defense Chuck Hagel confirmed. They will come out of “the next order to go on the assembly line,” he added, with delivery within two years. The V-22s are being built under multi-year contracts, the latest of which was signed earlier this year.
Companies proposing either tiltrotor or compound helicopter designs have won contracts from the U.S. Army for its joint multi-role technology demonstration (JMR TD) Phase 1 program to develop a next-generation vertical-lift aircraft.
AgustaWestland is flight-testing a redesigned vertical fin for the AW609 civil tiltrotor, part of an extensive package of aerodynamic improvements aimed at reducing drag by up to 10 percent, cutting weight and increasing performance. Other changes include new engine exhaust nozzles and modifications to the prop-rotor spinner cones.
In the midst of three new helicopter programs, Bell announced major changes to its executive leadership team in late August.
AgustaWestland is flight-testing several aerodynamic improvements that promise to boost the performance of its AW609 tiltrotor. In fact, these modifications reduce the tiltrotor’s drag by about 10 percent and deliver a “significant” weight reduction, resulting in the performance increases. The company is also upgrading the AW609’s turboprop engines, avionics and flight-control system.
While Bell Helicopter may be banking on its tiltrotor technology to recapture market dominance in U.S. Army aviation, the civil market will continue to rely on conventional helicopter design for some years to come, CEO John Garrison told AIN.
The tiltrotor test rig (TTR) development team at NASA Ames Research Center was honored today with a 2013 NASA Group Achievement Award. Team members include personnel from NASA Ames, Bell Helicopter and Triumph Aerospace Systems. The TTR is a joint project among NASA, the U.S. Army and U.S. Air Force to develop a new large-scale system that can test prop-rotors up to 26 feet in diameter at speeds up to 300 knots, allowing for advanced research on tiltrotors and other rotorcraft concepts.
Contract negotiations between the U.S. Army Aviation Applied Technology Directorate and AVX Helicopter, Bell Helicopter and the Sikorsky/Boeing team–the potential Phase I vendors for the joint multi-role technology demonstrator (JMR-TD)–are nearing completion. Announcement of the awards for a new U.S. Army medium helicopter are planned for September, according to an Army spokesman.
AgustaWestland has confirmed reports that certification of the AW609 civil tiltrotor has been pushed out to 2017, a one-year delay. A company spokesman told AIN that the schedule change is the result of numerous upgrades being made to the design in terms of aerodynamics and systems, including new engines, avionics and fly-by-wire flight controls.
