B-52 Stratofortress

Jschmus,

I found this in philp's pictures from the Nats.  It was entered in the humor category, but I think it's fairly accurate, don't you?

LOL!  I like it

[famvburg]

       That's what they said about the Hueys when the Black Hawks came out. I don't think it held true..........

Nice find. 

When the B-One and B-2 are finally retired it will be a B-52 that picks up the ferry crews and returns them to their duty stations.

Hmmm, with the new UH-1Y, who knows?

B-52: When USAF/Starfleet needs something to bomb the stuffing out of their enemies.

Brilliant!

RE: ASW, sounds like the USAF has made major steps in that direction, using the AN/ASQ-236 Dragon's Eye radar pod. From what I read, the idea is that a B-52 could provide perimeter defence allowing the fleet to concentrate on offensive rather than defensive missions.

Now I want to build one.

Agreed

[kerick]

It will never happen! The USAF has had every opportunity to reengine the BUFF and hasn't done it yet. I think it will be the year 2500 and these aircraft will be still be flying with TF-33s.

Clever model, no doubt!

[Captain Canada]

I bet they end up doing it.

"Analysts have identified the Pratt PW2000 engine, known as the F117 on military aircraft, as a potential replacement. That engine is used on the 757 commercial jet, which ended production about a decade ago, and the C-17 military cargo plane, which ends production this year.

Speaking the day before Holmes, Bennett Croswell, head of Pratt's military engines unit, told reporters his company has made "some very attractive offerings" to the Air Force.

Croswell said that while the F117 may be logical, in the past there were issues with control authority of the plane that could have required a re-wing to mount the more powerful engines. That problem has been solved, he said, and the company has offerings that can keep the eight-engine configuration."

As I recall, they thought about 4 Rolls Royce  RB211s  some time ago..........but I suppose that the Not Invented Here Syndrome would apply.  There's a lot of NIHS about!!

[jcf]

Mmm, yeah Boeing proposed the RB211-535 because of their experience with the engine on 7475767.

The major issue was the level of redesign required in the switch from eight to four engines, as the Pratt guy
stated, everybody was looking at basically re-designing the wing which would have rendered any $avings
moot.

PARIS: P&W developing upgrade package for B-52 engine
By: STEPHEN TRIMBLEPARIS Source:  6 hours ago
Pratt & Whitney is developing a proposal for a package of performance upgrades for the existing Boeing B-52 engine after
the US Air Force again postponed a plan to replace the venerable bomber's 60-year old TF33 engine.

Several four-engined solutions have been evaluated by the USAF to replace the eight TF33s on board each B-52H.

But the four-engined aircraft may not have enough rudder authority to counter the adverse yaw generated by an
outboard engine-out scenario, says P&W military engines president Bennett Croswell.

So P&W proposed a re-engined B-52s with eight new turbofan engines, but the USAF instead decided to postpone the programme,
he says.

The TF33 was derived from the original P&W JT3 turbojet engine that drove the first generation of jet-powered Amercian airliners.

P&W is developing an upgrade package to improve the fuel and maintenance performance for the TF33 through the end of its service life.
The USAF currently plans to operate the B-52 fleet to at least 2060.

So perhaps a four-engine B-52 would need the old D model tail? 

[sandiego89]

Tall tailed BUFF's always looked better to me.....

[PR19_Kit]

So perhaps a four-engine B-52 would need the old D model tail? 

My thoughts exactly.

But this must be at least the third time they've proposed a 4 engine BUFF so how come it's taken THIS long for anyone to come up with the 'lack of rudder authority' business?
