This made them slightly smaller than Allison V-1710s. In addition, Merlins had 12 cylinders in a V configuration, while Allisons had 10. In general, barring supercharging, they were very comparable. However, supercharging made all the difference in the world. Eh?What was the first to utilize a single-stage? Did the early PBY Catalinas (pre-WW2) have single-stage on their Twin Wasp engines?
Anyhow, a nice link about super and turbo-charging. Superchargers and Turbochargers
Yup, that was my point.BTW, the V-1710 Allison was a V-12 engine.
BTW, the V-1710 Allison was a V-12 engine.
The article is wrong. The V-1710 was a V12:This is a direct quote from the article;
"Rolls-Royce Merlins, which were named after a type of falcon rather than the magician, had 1,650 cubic inches of capacity. This made them slightly smaller than Allison V-1710s. In addition, Merlins had 12 cylinders in a V configuration, while Allisons had 10. In general, barring supercharging, they were very comparable. However, supercharging made all the difference in the world. "
Wot, a source worse than wiki?Other gems from the article:
Some British Merlin superchargers had three speeds.
F4F with a 2-Stage, 1-speed Supercharged Pratt & Whitney R-1830 Engine
In compensation, this delay allowed the Mk 60 and engines to have not only two stages but also two speeds and eventually three speeds for greater pilot control.
A P-40 with the same engine [2-stage Merlin] would still not be competitive with German opponents.
Second, it [P-47] used turbocharging for its second stage of forced induction.
In America, bombers typically used supercharging for the first stage and turbocharging for the second.
They also imply that Hooker improved S/C of the Merlin when going from XX to 45.
Don't think so, I am fairly sure the Allison had 1710 cylinders. Its right in the name!The article is wrong. The V-1710 was a V12:
Allison V-1710 Engine
I dread to think what people will be reading in 100 years time. There is an article doing the rounds showing 50% of people killed in the blitz on London were killed by British artillery, based on a study in 1938.Ohhh Kay...
I now see that was from the "article" - sadly, it's from a museum, too.
It's already happening in many "forums" out there with photoshopped images becoming "fact" along with old myths and propaganda creeping into canon.I dread to think what people will be reading in 100 years time.

The whole discussion about people in the blitz being killed by British artillery is to hang 50% of the deaths on Churchill. Tragic TBHIt's already happening in many "forums" out there with photoshopped images becoming "fact" along with old myths and propaganda creeping into canon.
I've seen a few sites that dwell on Dresden, for example, and they're actually using Goebbels as a source!
It's infuriating, in all honesty.The whole discussion about people in the blitz being killed by British artillery is to hang 50% of the deaths on Churchill. Tragic TBH

Did the Wildcat F4F have a two stage supercharger?
