Would'nt push that one too far codders... RR USE to make the best -- but these days GE have probably outclassed RR with the big fans. The real problem with RR was that they put too much faith in carbon composites way back with the developmnet of the RB 211.( 1972) A very good read on all this was the Sunday Times insight team - Paul Eddy . "DESTINATION DISASTER".

By the way did you know Rolls use to make small 2 liter diesel engines??
Its not that "british engineering " is crap "- its just, well , -don'k know where its gone???

and codders- just to show you I have checked my facts ( for once)


"..However the RB.211's complexity required a lengthy testing period. Things went further astray when the new fan stage, after passing every other test, shattered into pieces when a chicken was fired into it at high speed. (A short-term solution, replacing the fan blading with titanium, also turned out to be problematical, with the discovery that only one-side of the titanium billet was of the right metallurgical quality for blade fabrication). Rolls-Royce went bankrupt in 1971, forcing Lockheed into serious difficulties as well. Rolls was only "saved" by a loan from the US government arranged by Lockheed, (a highly contentious issue in both countries); and the taking of the firm into public ownership by the then Conservative governement. They were eventually able to deliver their first production machines in the early 1970s."

No Kernny they use live chickens. Its all about simulation, you see. They must simulate exact circumstances i.e a flying duck or an eagle.Ducks and Eagles are protected - Never heard yet about a flying frozen duck?????????

Well 85% of Operators choose the RB211 over the GE option........... Yes they did have problems with them in the early days - as most new technologies do - but now they go 19,000 hrs before overhaul - not bad!!!

What exactly do you base your FACTS on that GE are better???

Did you know that Allison who make helicopter engines and the ones on the Hercules are now owned by RR???

Also the Pratt and Whitney PT6 - the most popular turboprop ever was a RR design??? Or that the Labour government sold Russia 12 RR jet engines back in the early 50s which is what most Russian jets are based on

Or that Britain GAVE the USA all our research materials on early gas turbines so most of the Yank stuff is again based on British technology???

In fact Hawker Siddley and Bristol deserve much of the credit before they were swallowed up by RR - who incidently shit on poor old Frank Whittle big style!!!

And before anyone goes on about the German jets from the war they were crap - they say about German engineering - the early jets from the ME262 would only go about 20hrs before major overhaul the Whittle engine about 120!!!

I didnt say they were better- just that they have" surpassed RR on the big fans"--- Airbus 380 will use the GE big fan and not the RR.- and most Airbus 300/320 opeartors use GE engines. I am just as patriotic as you- and I do agree RR have been leaders in jet engine technology- and your stupid labour government in 1947 sold the ussr a RR nene turbojet which they copied very seriousely and came out with the brillant Mig 15 and 17 which caused havoc in Korea as it was able to outclass the sabre .Later on they developed the Mig 25 from the same engine - but you are probably aware of the problems that caused western defence chiefs.??

No they were frozen I met one othe the people who used to do the tests.
Always thought it would be a good thing to have on my CV …… ‘frozen chicken cannon operator’ or in MOD speak 'Avian air strike simulations officer'. Des

Why oh why do you not check the FACTS????

The first A380s use RR Trents and many have been ordered!!!

Selected by five out of eight operators who have so far made engine
decisions

Singapore Airlines (10 firm + 15 options)
Qantas (12 firm)
Virgin Atlantic (6 firm + 6 options)
Lufthansa (15 firm + 10 options)
Malaysia Airlines (6 firm)
Total: 80 aircraft (320 installed engines)
