There's a Lancaster bomber based in Hamilton (Canada) that flies over Toronto occasionally. Four Merlin engines together. Sweet.

Man I would sure love to fly a mosquito........





Little more on the Merlin.

From: http://www.vansairforce.com/community/showthread.php?p=81681#post81681

Now the 1650 cubic inch Merlin in airline service in the same era. Used by TCA, CPA and BOAC. Again life started out grim. TCA had 20 in flight shutdowns in one month! With takeoff power set at 1660hp at a staggering 71 inches. Cruise power was initially set at 40 inches and 1100hp. Engine life on wing was 200-450 hours in most cases. With a lowering of cruise power to 950hp, life picked up considerably. Over a one year period and 957 ocean crossings, 2 engines made it past 2000 hours, 7 made it to 1750 and the average life on wing was 654 hours (no jug changes on the Merlin). TBO was set at 1250 hours although this was just as meaningless as with the Wrights.

Initial problems were with the intercooler pump seals, compressor surging, coolant leaks and erroneous fire warning lights. Rolls Royce offered TCA a "won't be sorry" warranty on their Merlins- 6000 hours or 3 years. They would pick up the tab on any unreasonable wear or failures. RR probably lost money on this one! The Merlins on the North Stars were in a power egg which had rads and almost all parts attached in one piece for quick removal and replacement. Good idea. They needed it. It appears that very few Merlins had catastrophic failures- indeed, one was held at full takeoff power for 5 hours in a flight test until the oil supply ran low- pretty tough. Coolant leaks caused most of the shutdowns.

71 inches is a hell of alot of boost.  Course the Reno guys are running well over 120 inches.  :o

Back in the early days of Merlin development and production (one and the same due to the wr requirements) the Rolls Royce technical staff used to select random engines as they came of the production line, connect them up to the test rig, and run them at full power until they blew up.  They would then strip the engines down analyse what component failed, and strengthen it accordingly.

Using this method they turned the engine round from being one of the most unreliable in RAF service, to the most reliable, in considerably less than 12 months.

Of course all the while this reliability development was going on, they were also starting to increase the power outputs, which in turn was increasing the stresses on the various components thus increasing the workload of the engineers trying to find ways of keeping the damnd things running ::)

All in all, I believe the Merlin (and it's big brother the Griffon) must go down as one of the great engineering achievements, especially when you take into consideration the fact that all the while the above was going on, the Germans were doing their utmost to put Rolls Royce out of business, permanently :o

I answered a For Sale advert in the paper in a small town in New Zealand called Blenheim, where I worked, about ten years ago. So I walk out to the unattached garage with the seller and we start talking about all sorts of stuff to do with collecting. He said to me, "I've got a Rolls Royce Merlin engine, over there under that canvas".....And he did too. Unbelievable. It's a long story so I won't bore you with it....

Not sure what this airplane was called but it combined two of the Rolls/Merlin engines
and drove one prop !
Only one was built.--This may be a pic of the dual engine setup.

A good friend of mine lives very near to the Aerospace Museum at RAF Cosford. We used to love sitting out in the garden when they were running the engines up, beautiful music.
We also had grandstand seats for the yearly airshow  ;D
The Lancaster/spitfire/Hurricane flyby was always a great moment to watch and hear.
Though the Vulcan, when he pulled the nose up and hit the afterburners, was awesome too.

My bike can be repaired.
My insanity is a little more permanent.

Gerhed, Is that two complete Merlins, with individual crankshafts, side by side? Or is it a Vulture?

The Vulture was effectively two Peregrines (baby Merlins) mated onto a common crankshaft, creating a 44 Litre, 24 cylinder 96 valve 2000+hp monster :o As fitted to Avro Manchesters, and prototype Hawker Typhoons and Tempests 8) It was abandoned in favour of the more powerful and reliable Napir Sabre iirc.

The guy that had the Merlin had it gifted to him when his good friend, who owned it, died of cancer. The Merlin had a gearbox and it was for the left hand (port) wing of a Mosquito fighter bomber. They had props that rotated in opposite directions to offset the massive gyroscopic effects. As you know, the Mossie was made of wood and weighed just about nothing. The old man that died collected all sorts of stuff including Spitfire, P51 Mustang and Mossie bits and pieces. He sourced this stuff from Royal New Zealand Airforce Base Woodbourne, close to where he lived, in the 1950's and 1960's. He even had a coal fired steam train that he bought off New Zealand Railways way back when they converted to diesels. He built and designed his own home on the hills behind the town of Blenheim. About once a year he would fire up his steam train, which was on tracks underneath his house, and would drive (is that the right word?) it 20 yards or so out into the sunshine.

Of course, everyone back then thought he was an eccentric madman, but like us, he knew what he liked and he got what he wanted. If only I had as much foresight as he had. And of course the world needs more people like that.

Not sure.
The engine is at the Glenn Curtiss Museum in Hammondsport, N.Y.
I'll check on it next time I'm there.
I make a yearly pilgrimage.

When I was an air cadet in England I was lucky enough to be able to sit in the cockpit of one of the Battle of Britain Flight's Spitfires. Sheer bliss.

I sat in the one at the Brussels Military Museum. Scary feeling, imagin being chased by a BF109 guns blasting.
