Next week, a team from Textron Inc. and Bell Helicopter will demonstrate the maneuverability of its experimental V-280 Valor helicopter, a platform that may one day replace the U.S. military's UH-60 Black Hawk fleet.
The June 18 demonstration comes six months after the V-280's first test flight as a technology demonstrator in the Army's Future Vertical Lift program.
"It's not just a flight test, it's actually a demonstration of what we have been able to achieve so far," retired Army Maj. Gen. Jeff Schloesser, executive vice president for strategic pursuits at Bell, told Military.com.
"What you will see is the aircraft go through a variety of maneuvers. ... One of the things we want to demonstrate is just how able you are to quickly reposition the aircraft in flight," he said. "When you are on the objective area, you are not flying fast, but what you do have to do is do tail maneuvers, turn maneuvers, roll and pitch maneuvers in a very accelerated way."
I'm mostly angry with Sikorsky for shattering the Westland Lynx's speed records with a goddamned compound helicopter and then having the nerve to go bragging about it.
Bell’s V-280 demonstration programme plans to continue to expand the tiltrotor’s flight envelope, with additional focus on manoeuvrability, after reaching 250kt this September.
So far, the aircraft has been tested on 50˚ banked turns at 200kt, which is the equivalent of 1.8g, says Vince Tobin, Bell executive vice-president for military business. During upcoming tests the manufacturer expects the aircraft to fly turns that generate more than 3g, he says.

I can see the variable power thing being an issue, though I'd argue the duty cycle on the V-22's cross shaft is probably harder (with the caveat being that at least in any scenario where it actually performs as-designed, they'll consider themselves lucky if they even have a salvageable aircraft to rebuild the transmissions on when all is said and done).
The clutch just seems to me like another complication/possible failure point when a prop that feathers completely would accomplish the same thing, unless they're really *that* desperate to save a percentage point or two of powertrain efficiency. Like I said though, it seems like Sikorsky designed a hot rod that will struggle to carry passengers/cargo, while Bell built a flying truck that will struggle mightily as a more nimble/survivable attack platform.
Army pilots are scheduled to fly in the V-280 again over the next few days, Josselyn said during a media tour of the Arlington test center on Dec. 11. An Army test pilot and a U.S. government senior test pilot are due to fly the tiltrotor.
