B-52 Re-engining?

"Matt" wrote in message ...
It's kinda-on, but I believe they're currently arguing about 4 vs 8 engines.
The proposed 4-engine conversion uses the same engine fitted to the 767, so
it looks kind of ... dorky, I guess is the word.

Is the program to re-engine B-52 aircraft running?


I think the proposal was to lease Rolls Royce RB211-535E4s. They're used on the 757.
Only ever seen one pic of the proposal - does look kind of ...odd!

There's also a second proposal being looked at that would replace 8 with 8.
Sorry, I don't remember what type of engines would replace the TF-33. Latest
word is the 8 engine proposal is a little cheaper and prefered by Boeing. By
replacing 2 engines with 1 (with greater total thrust I might add) presents
some assymetric thrust problems should an engine be lost during a heavy weight
takeoff. Initially the RB-211 proposal included the "auto-rudder" which is
currently installed on 757s. This system automatically displaces the required
rudder amount for an engine loss. The problem in the BUFF, as anyone who's
ever done a 6-engine approach (done with 2 outboard engines on one side in
idle) or a 2-engine loss takeoff in the simulator knows, sometimes full rudder
isn't enough. The BUFF rudder is just too small. To solve the problem,
another automated system was going to be installed to automatically reduce the
thrust on the opposite outboard engine *and* increase thrust on the inboard
engines. By the time the automated systems were factored in, the cost had gone
up by a fair amount. Its still possible we may get 4-for-8, but right now
there's more attention on 8-for-8.

It'll be like Christmas in (insert month of first operational re-engined BUFF
arriving here). The proposal will also give us an upgraded avionics, which will
be worth as much to the average crewdog as the engines themselves.

Consider it a ten year life extension, in 2030.

At the rate they're going, you could be frozen for a thousand years,
wake up, and the only thing that you'll recognize will be made by
Boeing...

The thing that amzes me is a couple guys designed it in a hotel room
over a weekend. (Obviously they didn't do all the detail work but
still)

Hey BUFDRVR, you must have worn out those great engines.

I flew the B-52H at Minot when they were brand new. Still had the new car
smell. (1961-1966)

Hey BUFDRVR, you must have worn out those great engines.

Since 9/11/01 we've really flown the hell out of these jets. I've had a lot of
help wearing out the TF-33s.

What's this auto-rudder bit. In my years on the 757 with the RB-211's
there was no such thing.
