Jet Engined Lancaster Bomber?

Shortly after WW2 the British were trialling some of their new jet engines and decided to use an Avro Lancastrian, a passenger plane developed from the Lancaster bomber, as a testbed by removing the two outer Merlin piston engines and replacing them with Rolls-Royce Nenes. The first plane VH742 was by most accounts pretty successful. The problem I have though is trying to track down any solid information on what sort of performance it had. Would any of the resident aviation enthusiasts happen to know where I can find anything online?

The Short Sperrin which the government developed as a back-up to the V bomber programme whilst a couple of developments down the line wasn't massively technologically advanced and was able to turn in a respectable performance. Now what would of happened if jet research had been advanced faster in our timeline and they looked at converting Lancasters to jet power as an interim step? In completely unscientific fashion simply for the sake of argument knocking roughly 20% off the performance figures of the Sperrin since that's how much less less thrust the Nene produced than the Avon plus say another 5% for for it being less streamlined and extra things that need changing still gives some interesting figures for an alternate-Lancaster. Cruising speed of 400 miles per hour with a top speed of 450 miles per hour, range of just over 3,000 miles and a flight ceiling of 36,000 feet. Whilst something like this is sure to spur the Luftwaffe to advancing their own developments to counter, of the our timeline planes they fielded during WW2 other than the Dornier Do 335 right at the very end and the jet fighters they developed would they of had anything that could of significantly challenged them?

Wouldn't even have been considered. Early jets were a pain to keep flying - engines burned out and needed a total overhaul VERY quickly. And the British had a policy of not letting jet engines get where the Russians could look at crashed ones. Ironically the first post-war Labour PM Clement Atlee sold the USSR 40 Nenes: they reverse engineered them and - Idiotlee was horrified! - used them in the Mig 15 without even paying a licensing fee.

I have to quote the wikipedia article:

http://en.wikipedia.org/wiki/Klimov_VK-1

in 1946, before the Cold War had really begun, the new British Labour government under the Prime Minister, Clement Attlee, keen to improve diplomatic relations with the Soviet Union, authorised Rolls-Royce to export 40 Rolls-Royce Nene centrifugal flow turbojet engines. In 1958 it was discovered during a visit to Beijing by Whitney Straight, then deputy chairman of Rolls-Royce, that this engine had been copied without license [1] to power the MiG-15 'Fagot', first as the RD-45, and after initial problems of metallurgy forced the Soviet engineers to develop a slightly redesigned (and metallurgically closer) copy, the engine had then entered production as the Klimov VK-1 (Rolls-Royce later attempted to claim £207m in license fees, without success).

The comparatively simple RD-45 proved troublesome due to Soviet inexperience with engineering and materials,[dubious – discuss] but was further improved to produce the VK-1 which differed from the Nene in having larger combustion chambers, larger turbine, and revised airflow through the engine. The Soviets partially tackled the metallurgical issue by touring the Rolls-Royce plant in specially-designed shoes intended to pick up metal shavings for later analysis.

Specially designed shoes! It's so Boris-and-Natasha, but it worked...
 
The Russians? I know that they had a policy of not using jets over enemy territory because they were afraid that the Germans could capture examples of them, were they really thinking all that much about the Russians during the war?

The first Meteor squadron wasn't deployed to the Continent until the beginning of '45: at that time there was little point in worrying about the Germans, because they wouldn't have time to anything with a Meteor if you landed one in front of Goering's favourite pastry shop and pushed the operating manual down his trousers. But conflict with the Soviets was a very real possibility. Remember that the British had gone to war over the freedom of Poland and that Sovs had already swallowed it down. The only reason that the UK did not try to get the US to declare war on the USSR to liberate Poland et al was that it was far too powerful:

http://en.wikipedia.org/wiki/Operation_Unthinkable

Operation Unthinkable was a code-name of two related plans of a conflict between the Western Allies and the Soviet Union. Both were ordered by British Prime Minister Winston Churchill in 1945 and developed by the British Armed Forces' Joint Planning Staff at the end of World War II in Europe.
The first of the two assumed a surprise attack on the Soviet forces stationed in Germany in order to "impose the will of the Western Allies" on the Soviets and force Joseph Stalin to honour the agreements in regards to the future of Central Europe. When the odds were judged "fanciful", the original plan was abandoned.

- The Soviets had numerical superiority in ground forces in Europe of 3 to 1, and were almost inarguably qualitatively superior as well.

Force for air resistance is a square law, so I'd expect your Jetchester to have the square root of 0.8 of the maximum and cruise speed of the Sperrin - about 90%.

It was probably during late 44-45 that the British didn't want Jets over Russian territory since they were capturing pretty much all of Europe.

Not just over Russian territory: wreckage from any jet lost over German territory would be examined by German experts. Who wouldn't have time and resources to do much for Germany with it, but some of who probably end up with the Soviets.
 
A jet powered Lanc might have been a possibility to bridge the gap between the Lincoln and the Canberra. I know, the B29 'Washington' sort of did that.
 
Given jets offer higher performance at higher altitudes, ISTM the better option would be jets on a B-24 wing.

So, the question is, what are you trying to achieve? The earliest jet bomber possible? Or the best one early? Or just a boost to existing bombers?
 
The reason that performance figures might be hard to come by might be because they weren't testing the Lancastrian, they were testing the engines. An all-jet Lancastrian may have been able to exceed the airframe's Vne, which wouldn't prove anything.
 
Does the 3,000 mile range look possible?

Not even close. The Lanc carried 2154 I gal. internally and could carry 1 or 2 400 gal Bomb bay tanks in lieu of bombs to achieve a 3,000 mi range, with Merlins. The Sperrin carried 6200 gal. The Il-28 Beagle was powered by 2 Soviet Nene engines and achieved a range of 1490 mi on 1737 I gal.
