WASHINGTON — Bell’s future vertical carry know-how demonstrator, the V-280 Valor tiltrotor, has completed its flying profession, based on a June 24 firm announcement.
The demonstrator was constructed for the U.S. Military Joint Multi-Function Expertise Demonstrator program and flew for the primary time in December 2017. It spent the final three-and-half years proving out the service’s necessities for a future long-range assault plane, or FLRAA.
The service continued flying the demonstrator past the JMR program in a two-phase aggressive demonstration and risk-reduction effort.
Bell will proceed into the second section of the risk-reduction effort “to supply preliminary preliminary designs for main subsystems and the conceptual weapons system, based mostly on data-proven efficiency that ensures transformational capabilities will likely be delivered according to the Military’s schedule,” the corporate mentioned in its assertion.
The Military is near releasing its request for proposals for FLRAA that can kick off the official program of document. Bell is predicted to compete in opposition to a Sikorsky-Boeing group that additionally flew a JMR know-how demonstrator — the SB-1 Defiant coaxial helicopter.
The service is on a path to obtain two new vertical carry plane by 2030, pursuing a future assault reconnaissance plane, or FARA, along with FLRAA. Bell and Sikorsky are competing in opposition to each other within the FARA competitors, and every is constructing an plane for a primary flight in fiscal 2022.
Though Bell’s first V-280 know-how demonstrator is retiring, the know-how and classes discovered from the primary plane will dwell on within the firm’s resolution that will likely be submitted for the FLRAA competitors.
Over the demonstration and risk-reduction section, the V-280 flew greater than 214 hours and confirmed off low-speed agility and long-range cruise capabilities, and reached a most 305-knot cruising pace. The Military’s threshold requirement is predicted to be within the 230- to 250-knot vary for the FLRAA program of document.
5 Military experimental check pilots have flown the V-280 over 15 sorties, based on the corporate assertion. The corporate used suggestions from Military pilots, mechanics and infantry squads to assist inform design plans.
Additionally by means of the V-280 program, Bell offered “intensive” knowledge explaining how its plane, by means of the incorporation of a modular, open-systems method, brings effectivity to a future program.
“We’ve got come a great distance since we began our journey eight years in the past. We made commitments, we safely executed our program on time, and we validated our efficiency claims and the accuracy of our digital fashions by means of flight demonstrations,” Ryan Ehinger, Bell’s vice chairman and program director for FLRAA, mentioned within the assertion. “Finally, the Military doesn’t ship warfighters into battle using at the back of digital fashions and so we thought it was essential to convey that bodily proof.”
“The FLRAA problem introduced by the U.S. Military was unattainable utilizing helicopter configurations. They’ve been clear about the necessity to modernize and area transformational capabilities,” Keith Flail, Bell’s govt vice chairman of superior vertical carry techniques, mentioned within the assertion. “We assessed a number of vertical carry applied sciences and decided the tiltrotor to be the one resolution to the agility, vary, and pace necessities of a Lengthy-Vary Assault Plane that may meet the fee, timeline, and threat profile required for a profitable acquisition program.”
