AUSA: Lockheed Martin company Sikorsky and teammate Boeing are taking a deliberate approach to building their prototype for the Army-led Future Vertical Lift (FVL) program, the SB>1 Defiant, officials told our contributor Richard Whittle when he visited their booth. Based on Sikorsky’s award-winning X2 technology demonstrator, the Defiant is a compound helicopter with coaxial rotors…
By Richard Whittle and Colin ClarkBell’s V-280 tiltrotor didn’t take flight – not yet – but it has tilted its rotors into helicopter mode and spun them up during its first-ever “restrained ground run test.” This test mode plugs the whole aircraft into a bulky apparatus to ensure it doesn’t take off by accident. (That would be bad). The test…
By Sydney J. Freedberg Jr.AMARILLO, TEX.: The Future Vertical Lift program aims to create revolutionary replacements for today’s military helicopters. But how? And why? The answers lie in the speed limits built into the physics of how a helicopter flies. Rival contractors Bell and Sikorsky (part of Lockheed Martin) both say they have transcended those limits to build dramatically…
By Sydney J. Freedberg Jr.WEST PALM BEACH, Fla.: The United Kingdom is following the U.S. Joint Multirole Technology Demonstrator (JMR-TD) project with “great interest” and might either get involved at some point or buy future aircraft the effort spawns, says a top British Defence Ministry rotorcraft engineer. “It’s a perfectly feasible outcome,” Bryan Finlay, the senior engineer at the…
