744 With PW "screamer" Engines?

Tue Jan 16, 2001 7:22 am

Do any 747-400's today have the old Pratt and Whitney "screamer engines which we so commonly see on older 747's?

I recently saw a computer graphic showing the 747IGW in Qantas livery with those engines? so is ths out dated form of engine to be used on a top of the range new aircraft??

To my knowledge, nobody flies a 747-400 with the old Pratt and Whitney JT9D turbofans. People can get confused with the 747-300 which looks very similar to a 747-400 but uses P & W JT9D engines. Boeing built 2 747-100B's with the stretched upper deck (SUD) of the 747-300 which makes it look like a 747-300/400, but these were hybrid aircraft and designated 747-100B(SR/SUD). A picture and more info about these hybrid 747's is in the book "Boeing 747: Design and Development Since 1969" by Norris and Wagner.

I am aware of these aircraft but the plane in the computer graphic I was referring to (which by the way is in the latest edition of Australian Aviation magazine) was the soon to be made 747IGW<<

The only models of the 747 that had the JT9D were the 100/200 & 300. If you see picture of a Swissair 747-300 you will see the JT9Ds.

I think Qantas747-sp is referring to Boeing's CGI of the upcomming B747IGW as below.

The engines do look suspiciously similar. But I'm quite sure that's an oversight on the part of the artist or that the new engines do share an uncanny similarity afar but not technologically of course.

Is it me or does the JT8D's on the 747-100/200/300/SP sound the best? I think they sound the coolest out of any plane I have herd. The 777 w/ PW comes close though

What engines did Qantas order these aircraft with? I thought they usually use RR engines on 744s.

AA61hvy - you'd need about a dozen JT8s to power a B747 - I agree that it would sound spectacular, though!

If it's anything like the Airbus order Qantas is yet to select the engines.

What engines were Boeing offering on the IGW?
