New Bell battlefield product - Bell V280 Valor
As I said on the rotorheads page, I was on my FB account and subscribed to Bell FB page and saw the countdown to revealing big news at Quad A

Cost per unit?
One wonders.

Yes, but note the subtle difference:
The transmission rotates, and the engine stays facing fore and aft. Interesting variation on Osprey.

Thanks Lonewolf, I'd missed that. Does it mention why Bell decided to do it that way? Must be an interesting gearbox! (Yes, I'm an engineer, is it obvious ;-))
I guess the redesign is due the terrible experiences of the rotating engines on the V-22. After so many fatalities they reduced the vulnerability of the engine to ground-strikes but the lack of ground clearance is still a concern to operators and the jet efflux is less than ideal too. This design (if it works) looks much more appropriate for an aircraft you plan to land in the dark, on uneven terrain in a threat environment.
The internal bomb-bay looks interesting.

Well shiny brochures, CGI videos and images of prototype/development aircraft bouncing about seem to have convinced many of the pro-JSF crowd.
They have some JSFs in The Avengers Assemble you know? How much more proof do people need of its abilities? It stars alongside Iron Man and The Hulk!

Sikorsky Aircraft Corp., a subsidiary of United Technologies Corp. and Boeing will submit a joint proposal to build a demonstrator aircraft based on Sikorsky’s X2™ Technology rotorcraft design for the Army’s Joint Multi-Role (JMR) Technology Demonstrator (TD) Phase 1 program.
The JMR TD program supports the U.S. Army’s Future Vertical Lift (FVL) initiative to deliver the next generation of vertical lift utility and attack aircraft.
“The Sikorsky-Boeing proposal will demonstrate how X2 Technology with counter-rotating coaxial main rotors and a pusher propeller, and advanced fly-by-wire system, will deliver efficient 230-knot cruise airspeed, improved hover efficiency, and weight optimized design in an affordable package,” said Samir Mehta, president of Sikorsky Military Systems. “By leveraging our proven design, we can offer the Army reduced risk, a 100-knot improvement in speed, a 60 percent improvement in combat radius and 50 percent better high-hot hover performance.”

This is all being run by moles from Eurocopter and AgustaWestland. The idea is to cement their global domination by spending another two decades of USG research money on something nobosy wants.
Seriously - I like the X2, which is promising. But the complex won't allow Bell to be excluded, so everyone's idea has to be funded.

Ah, the Rotodyne. Its main drawback was the noise. I lived near White Waltham. You could hear it coming for miles! Not much good for a stealthy special forces insertion.
On the other hand, it sounded exactly like a steam engine - a GWR Castle Class to be precise.
So maybe the bad guys would have been fooled. "No, that's not a helicopter. It's the 6:50 from Paddington."

Why must we keep re-inventing the wheel and making uneccessarily complex?

If it does the job then why not?
The point I was trying to make was It is a working design which with mdern production methods, Materials, and avionics etc could make it quieter, Faster, Longer legs etc. Why not dust of the plans and see what BAE make of it?
Ah - I see the flaw...
