Ah the memories. In 1984 a shiny new Army Cobra lieutenant went to his first Army Aviation Association of America annual meeting in Fort Worth Texas. Aside from the copious amounts of alcohol, there was a convention center chalk full of LHX models and mockups. Bell tactical tilt rotor...

@ Sundog - to your point on V-280, I suspect that Bell will start on the "operational" issues, since the air vehicle seems not to have any issues with flying. Things like: "our aircraft has only six rotor blades, all of which can fit in the back of a small tactical vehicle. We can work on the...

I very much doubt that SB>1 will not be OPERATIONALLY air transportable, not due to cabin size, but more so that the transmission and rotor hubs would have to be pulled to fit the aircraft into an air transport. To the point F-14D made, this may be the upper limit of sizing for X2 (ABC). Did...

Sometimes, "if you build it they will come" (Strike Eagle -> F-15E). Sometimes not (F-20, Mirage 4000, and many others).

Mr. Whittle is one of the more knowledge defense rotorcraft writers. I think his point is that there will not be fleets of dark green compounds or tilt rotors with US Army on the side for some time. Earliest we might see a JMR aircraft flying is 2017. S-97 is not a JMR candidate. Yes it is...

And it could fly at 27,000 feet. Downselect on AAFSS was only six months before the Johnson-McConnell Agreement. AAFSS also passed on the Boeing tilt wing which probably had similar high performance. Another element suggested by Robert Bradley is that adopting a VTOL plane like this would have...

Not wishing to start an argument here, but then why do you think Piasecki got dropped? After all they have been flying their SpeedHawk around for a while. May not have met all its goals yet on its shoestring budget, but it did fly and demonstrate their concept, and their rotor is even more...

Good discussion here on JHL: http://www.secretprojects.co.uk/forum/index.php/topic,2765.msg22117.html#new Actually there are two efforts that will go forward for further analysis (both TR) and Sikorsky appears to be planning on re-investigating the variable diameter rotor concept although I am...

@_Del_ - Thank you for these great insights. Your comments make me go back to my question regarding the disperity between two corporate methodologies for proposal writing as they merge. As with many I suspect there were significant differences in philosophy.

They should hear what naval-minded people say when they see it.

Bell switches engine supplier for next tiltrotor, chooses GE By: Jon Hemmerdinger Washington DC GE Aviation will manufacture the engines for Bell Helicopter’s third-generation tilt-rotor aircraft, the V-280 Valor, according to a media release from Bell. Bell, a division of Textron, does...

"Foreign Militaries Eye Sikorsky S-97 Raider" by Brendan McGarry Wednesday, May 7th, 2014 1:50 pm Posted in Air Source: http://www.dodbuzz.com/2014/05/07/foreign-militaries-eye-sikorsky-s-97-raider/

Here's the thing. Regarding the hand laying of blades, and the delay, keep in mind that the over one year delay was from a date that Sikorsky had said they would have no problem meeting, and then they kept missing their own revised dates. Both the X2 demonstrator and S-97 experienced flight...

The outlier in this is the USMC H-1 replacement effort. The Marines have made it clear that they want a tilt rotor solution. So there is a logic that Army gets SB>1 (Sikorsky and Boeing get paid), FARA is canceled and Marines get a V-280 variant (Bell is paid). Politically, everyone is still...

It's actually superior to both (I hate to say it as I'm a CL-84 fan, but who knows where that would have led had it been produced in the 70s) since it's not blasting the landing zone with hot exhaust. Now produce ASW and AEW variats for the USN and allies with STOVL carriers. I also really...

A shame they're not using the Zumwalt hull for the Tico replacement.

Like all other things with the government there are specifications laid out for what constitutes the minimum criterion for maneuverability by weight class. Don't recall the exact nomenclature for the document, but I would expect if the V-280 cannot at least maneuver to the standards of the...

Agree with all. I would not be surprised at all to see keen military interest in S-97.

Isn't JMR-Medium intended to replace the Sikorsky UH-60 Black Hawk and variants in the United States inventory? What is the United States Navy going to use to replace the SH-60 Sea Hawk? The United States Air Force the MH-60/HH-60 Pave Hawk? The United States Coast Guard the HH-60 Jay Hawk? The...
