Well, if you read carefully what I have written in this discussion, you will notice that I have not questioned 500mph speed claim by the Republic. Infact I'm mostly having fun and also collecting nice written material for future discussions about the supposed 3200rpm rating of the P-38L and propeller tip speeds in that case.
Well Harri, those of us who know you understand that you take great joy out of being a troll.
BTW, the P-38 has serious trouble with tip speeds at altitude, only exacerbated at full rpm. You might notice that the P-51J, powered by a mechanically supercharged version of the P-38's V-1710-119, also suffered by tip speed losses at 3,200 rpm.
(that's right, North American used full rpm limits) This problem would have been partially offset had the WPB accepted the P-38K with its .423 reduction gear and "paddle" blade props. According to Tony Levier, the K was about 40 mph faster at 40,000 ft than the P-38J-1-LO, on less horsepower.
That exhaust thrust discussion just came as a nice little bonus. And actually some respected aviation writers seem to have some doubts about that mach 0.76 claim like F.H. Dean.
I happen to know Diz Dean. He's a very nice man, sneaking up on 80 years old. Nonetheless, no one in the industry would classify Diz as a "writer". He's skilled at compiling data, making sense of test reports and explaining the engineering. However, a writer he isn't.
Now, where does he express doubts about Mach .76?
And then to the exhaust thrust. First it should be noted that you made a statement so it's generally your problem to prove it.
Says who? I offered the figures quoted by Higginbotham. He was the engineer in charge of Republic's powerplant engineering department. Proving what he wrote is easy, I have a copy of the letter. Proving their theory is not my concern. However, I put a great deal more credibility into Higginbotham's numbers than yours. He was there doing the testing.
Why is it every discussion with you results in you dropping your pants and producing a ruler? Any time someone makes a technical error, you attempt to pound them over the head with it. Are you insecure? There must be some deep-rooted cause of your dickhead behavior. I know the cure, but you're not up to it.....

Well, actually I was hoping to see at least 50 lines about how great knowledge you have about these things and how minimal my knowledge is. But I was not disapointed when I saw that nazi and weasel stuff, thanks.
I suppose that I could have dedicated 50 lines as what an accomplished amazinhunk you are. However, your own trolling and condescending words have done that far more efficiently than I could have managed in 100 lines. BTW, where did I refer to you as a Nazi?
Toad,
I admit that I have been wasting bandwidth here and I also admit that I have been kidding someone.
That's double-speak for "trolling". Harri is a master at double-speak, carefully mis-interpreting English text to suit his need.
BTW did you know that I teached tip speed and roll rate theories to CC/Widewing? Want a prove? Try Google...
Geez Harri, "teached"? I admit, Harri did correct some misconceptions about roll rate theory. However, I do not recall ever discussing tip speeds. Unfortunately, Harri never endeared himself to the crowd at rec.aviation.military, for the same reasons he has not done so here. Harri is certainly well educated, and seldom misses an opportunity to point that out. What he lacks are the basic social skills found this side of a rattlesnake's hole. He won't let minor issues such as honesty and truth get in his way either.
It's amusing, I run into guys like Harri at the gym all the time. Frequently, while I'm sparring, they ask to go a few rounds for a workout. Almost without exception, they attempt to take advantage of the "old man" by stepping up the effort, ignoring club rules about intensity and trying their best to knock me silly. What they don't know, but quickly discover is that the "old man" is in better shape and has much better skills than they. Too bad Harri isn't into competitive boxing...
Naw, that would be too easy...
I am not an aeronautical engineer. Nor do I claim any special knowledge. I do, however, have access to a very large collection of personal correspondence, both written and recorded. In addition, I have access to Warren Bodie's huge collection. When I quote from any of these records, I cannot, nor am I inclined to "prove" what is stated. I am merely reporting what was said or documented. Now, if someone like Gripen has a problem with that, well, tough toejam.
My regards,
Widewing
