Was the Pratt & Whitney Double Wasp the best engine of WW II?
The Pacific was a "sideshow" ???? Tell that to the men who fought there,
including my Grandfather.... As to the R-2800... Ask anyone who has ACTUALLY flown a round engine... The shake, they leak, and when a cylinder blows completely off they still get you home. Been there, done that. The fact of the matter is that both the Packard-Merlin and the P&W-2800 were excellent engines in their time. Each had it's strong points, and it's weaknesses. Ruggedness went to the P&W. Fuel efficiency went to the Merlin. Both powered excellent aircraft. Arguements about which machine was best are silly. The real discussioin should be about which men were the best. Men win wars, machines don't. OL |

Was the Pratt & Whitney Double Wasp the best engine of WW II?
It seems that I either dash off messages before I get them right, or I
hone them untill they are perfect, and I never get them posted. First problem with my message was that it was "after the fact". I have to remember to quit arguing when other people change their position. Sorry. On Sat, 06 Jan 2007 05:09:01 GMT, "Overlord" wrote: The Pacific was a "sideshow" ???? Tell that to the men who fought there, including my Grandfather.... No point asking. In "Up Front" Joe says to Willie "I don't give a damn what they say, this is the most important hole in the world, I am IN it!" A side show for deciding which was the best engine. I was thinking about that, and it is really scary that we came very close to losing more people in the secondary theater than we did ni the primary one. Jeeze! As to the R-2800... Ask anyone who has ACTUALLY flown a round engine... Asking anyone who has flown a radial, and only a radial is just the same as asking the guy if hile is important.

Men win wars, machines don't. As an engineer, I tend to think about machines, and if I think about men, it is mainly the ones that made the machines! It is easy to find cases of brave, heroic men who lost because they had the wrong machines, or had some other "system" failure. Henry_H. OL |

First they had the "Wasp" and then they had the "Twin Wasp". The "Twin" didn't mean what I once thought that it was composed of two banks that were "twins" of the singel row version. It just mean that there were two rows. Then they had the "Double Wasp" which was, fairly close, two "Wasps". (stuff that gave me a hard time snipped) The Pacific was a whole different story, and the R-2800 was more important there, but lets face it, the Pacific was a sideshow. Yeah. Pearl Harbor, Doolittle, Corregidor, Bataan, Guadalcanal, Midway, Hiroshima, Nagasaki .... why do historians even bother mentioning them? No one said that side shows couldn't be interesting. BTW AFAIK, there were no R-2800s involved in any of the spots you mention. I guess that the engines that were the U. S. "MVPs" in those cases we Pearl Harbor R-1830 Doolittle C-W R-2600 Corregidor Bataan Guadalcanal R-1830 Midway (I have to think about that) Hiroshima C-W R-3350 Nagasaki C-W R-3350 There were few, if any Merlins, either. The ETO wouldn't turn loose of them. ..... why do historians even bother mentioning them? Too much time on their hands? Actually, as I already said, the Pacific was important, it just wasn't the "engine showcase." Henry_H. Sheesh!!! BobbyG |

As far as the comments go, more energy has been wasted arguing about terms like: best, first, fastest, highest, most, etc, etc. Regional, National, Corporate and individual egos get wrapped up in this passionate discourses and no one's opinion is ever changed, and no one winds up satisfied. I ever am entertained by all the qualifiers and modifiers that folks wax eloquent with in order to support their position. You start with a superlative, and then add so many adjectives and adverbs that the claim really means nothing! (For example, don't try to tell a European or Brazillian or Australian or Russian that the Wrights were the first to fly!) What's wrong with "one of the . . ." Now to the argument, I spent many hours in the Navy being thrust through the skies by R3350s and J-79s and feel they are both remarkable, important engines. However, I do consider the R2800 the better engine, and certainly more relable and mechanically elegant. On many levels, when compared to any other engine in WWII, when all factors are considered: power to weight, reliability, variety of application, longevity, maintainability, cost of manufacturing, or any other I can think of, Pratt & Whitney really hit a home run! One indicator, was when neophytes would ask what the difference was between the similar appearing DC-6s (2800) and DC-7s (3350) the standard reply was the former had four engines with three bladed propellers, while the latter often was powered by three engines with four bladed propellers!
