Thanks for the link. Loved it. Somehow I have always connected more to the not so well-rated US designs (like the P-38!)
What an effort they came up witth, incredible.

Only 5 parts being identical to regular P-51s was a big WTF moment to me...

"On 31 December 2018, our XP-82 Twin Mustang flew for the first time since 14 December 1949. Although it wasn’t supposed to fly yesterday, all that was planned to do was the last FAA required runway high-speed taxi test, lift off for a second or two and then back down, deploy full flaps and brake to a stop. It accelerated so fast after the planned lift off that Ray, our test pilot, realized that getting it back down and stopping it in the remaining runway would be marginal. So he pushed the power back up and flew for about five minutes.

The unexpected and dramatic acceleration of our XP-82 at 55 inches of manifold pressure occurred because it was approaching three times the horsepower of a single engine Mustang and one and a half times the weight. The XP-82 has 1860 hp each side for total of 3720 hp, compared to 1500 hp for the P-51. Our XP-82 weighs approximately only 1 1/2 times more than a P-51 - 14,700 lbs. compared to 9500 lbs. for the P-51.

The very short gear-down flight showed zero airframe squawks, hands-off no trim required, with all engine temps and pressures normal.

This wonderful test flight came after a 10.5 year restoration encompassing 207,000 labor hours. Many thanks to Ray Fowler, our test pilot and all of the men and women that made this restoration possible. Thank you, Tom Reilly."

The P-51 Mustang, the aircraft that the XP-82 is based on, has to be the most important and decisive aircraft ever built in the history of aviation and aircraft development. One thing is sure, it was a game changer and without it, the Air War in Europe during World War II would not had won by the Allies.

The P-51 was developed for the British and their R.A.F. and they didn't want it because it was a dud. An under performing fighter compared to their Spitfires and Hurricanes. It was only after the original American made engine was replaced by a British Rolls Royce engine did the P-51 became the famous game changing fighter it's now known for.

You vastly overstate the Mustangs importance. The Air war in the ETO would still have been won with P-47's, Spitfires and P-38's if not for the Mustang.

The P-51 Mustang (with its 3 internal fuel tanks and 1 drop fuel tanks under each wing) allowed fighter escort for the American and British bombers all the way deep into Germany and back. Also it was capable of 455 mph at 35,000 feet.

Hey, Nofly. It would be awfully nice if you knew what the hell you were talking about. Most important airplane in history!!? Are you kidding me? The air war would not have been won without it? The early Mustangs weren't "duds" and it just so happens the British DID like it. They used them at low level for, what they called, Army cooperation missons. The USAAF called it Tactical Reconaissance. At sea level, it was one of the fastest airplanes in the world. That's with the Allison engine.
They liked the airframe so much, in fact, that they thought it was worth trying out a Rolls Royce Merlin in it.
The airplane was great, but could the air war have been won without it? Yes. Because Republic designed the P-47N, and had there been no Mustangs, those are the fast, long range fighters that would have wound up escorting 8th Air Force bombers to Germany. Instead, not needed in Europe, P-47N's flew long missions to Japan from Ie Shima and Iwo Jima. VLR missions...very long range.
And the P-51's used during the second world war had a top speed of 435 MPH, not 455.

Maybe you need to Google some, Pooch before you criticize me.

You mention the P-47? Read this:

https://nationalinterest.org/blog/b...smash-hitler-and-win-world-war-ii-124091


One paragraph on page 1 says:
Quote
The bombers were escorted for parts of the missions by U.S. Republic P-47 Thunderbolt fighters, but because of their limited range they could only go as far the western German border.


Another paragraph on page 3 says:
Quote
In May 1941, Lt. Col. Bob Olds was given the task of organizing the ferrying of Lend-Lease planes to England. He was an advocate of adding range to all fighter aircraft to increase their ferrying capability. As part of that effort, Lockheed and Republic were asked to increase the range of the P-38 and P-47 fighters they were producing. The modifications of these aircraft, essential for any escort role, were pushed forward to increase their ferrying range, not their combat range. Thus, by chance the P-38s and P-47s delivered to the Eighth Air Force in 1942 (P-38) and 1943 (P-47) were given the capability to extend their combat ranges. With the addition of the tanks, these fighters could escort the bombers farther but still not far enough. They could not go all the way with the bombers on deep strikes into Germany. German fighters would learn to wait and attack the bombers after the escorts had to turn for home.


again, on page 3, another paragraph:
Quote
The original Mustang as designed for the British had an underpowered Allison engine. It did not perform well at altitudes above 15,000 feet. It was pure serendipity that a pilot who flew one of the early British versions suggested its performance could be significantly improved by replacing the Allison engine with the same Rolls-Royce Merlin engine that powered the RAF Spitfire. That idea was the stroke of genius that made the Mustang a great high-altitude fighter. It matched or bettered the performance of any German fighter except the Messerschmitt Me-262 jet fighter that entered operations too late to affect the outcome of the air war. But even with external drop tanks, the P-51 did not have the range to escort bombers on their deepest penetrations into German territory. It took further design work to come up with a fix.

In the summer of 1943, North American was told to add another 200 gallons of gas storage to the P-51 design. The head of the company said that it was impossible to accomplish because the landing gear would not hold the additional weight. He was told to try it anyway. He did. Schmued was able to modify the design to provide for an 85-gallon fuselage tank to the rear of the armor plate behind the pilot. With further design modifications, the P-51 with the internal tank plus 108-gallon drop tanks could fly to Poland, a round-trip of 1,700 miles, at speeds approaching 440 miles per hour and at altitudes up to 40,000 feet. It was now the fuel load of the bombers that limited the range of Eighth Air Force strikes.


In this: https://www.questia.com/library/journal/1G1-191999630/
Quote
Maj. Gen, William E. Kepner, of the Eighth Air Force Fighter Command, who wrote, the-p-51-mustang-the-most-important-aircraft-in-history This makes the P-51 the most important aircraft in history. I define most important as (1) the aircraft that provided a major change in the direction of a major war and (2) one that was irreplaceable; no other aircraft could have provided this critical capability at that critical juncture.


Also read this starting at page 36 but if you want to read the first 35 pages too, go ahead, you will learn something. https://digitalcommons.lsu.edu/cgi/viewcontent.cgi?article=2218&context=gradschool_theses

Only the P51 was able to escort B-17 and RAF bombers deep into Germany and back. The P-47 and the P-38 were good planes but even with their fuel drop tanks, they did not have the range the P-51 had.

re P47 range, please watch this vid


It is rather long , but helps explain some 'shenanigans' re P47 range- it's quite illuminating
Posted By: Vaderini

Re: XP-82 Twin Mustang - 09/04/20 09:06 AM

I can wholeheartedly recommend the video bolox has posted, it really is an excellent video. And some questions to make yourself question your own reasoning:

Quote
the most important and decisive aircraft ever built in the history of aviation and aircraft development.

Why is the P-51 more important and decisive than the Wright Flyer, Heinkel 178, or the Boeing 747? What would've happened if the P-51 never existed?

Quote
One thing is sure, it was a game changer and without it, the Air War in Europe during World War II would not had won by the Allies.

Why was Germany incapable of winning "the Air War in Europe" before the P-51 arrived? Why did the Luftwaffe bleed dry on the eastern front without the P-51 serving in any relevant numbers?

P-38s were the first American fighters over Berlin.

P-47s of the 56th FG did reach Berlin in 1945.

Re: XP-82 Twin Mustang - 09/04/20 03:59 PM

Yes, and the P-47 I mentioned quite clearly was the "N " model. Not the short ranged D's that served in Europe. The P-47N was the last major developement of the airlplane and was one of the longest ranging single engined fighters of the war. First of the Thunderbolts to have a wet wing.
Oh wait, is this supposed to be about the F-82?

I wouldn't go that far with such a declarative statement. Just because we're older doesn't mean we are stubborn because we are set in our ways. Consider that we have cumulative knowledge built up over the years that we draw from, and the wisdom that this brings. We're not closed minded, we simply have a much broader, in-depth pool of information to draw and extrapolate from stored in our heads.

You won't believe how many times I've said, "Gee, I was such a little dumbarse," to myself over the years as I grew older. I swore I knew everything when I was seventeen. In my forties I now realize that I don't know nearly as much as I thought I did, and I bet by the time I'm as old as my grandparents were, that I'll come to the conclusion, "I don't know a #%&*$# thing."

Let's see... I'll be SEVENTY in January. I am a Junior in college with a 3.4 GPA in my major, and a 3.05 GPA overall including classes I took in the seventies and didn't do real well, including a D and an F, which brings my overall down a bit.

I learn new things everyday whether it's in school, painting, gardening, cooking and/or reading or watching things of interest on the web.

Don't worry, you'll figure it out. I knew everything in my teens and twenties too.

Re: XP-82 Twin Mustang - 09/04/20 07:40 PM

The P-38 (at least until the J-25) was too unreliable in the cold temperatures common at high altitude over Northern/Western Europe. It was also considered too complicated by some (though certainly not all) of the ETO pilots.

The XP-47N did not fly till mid-1944, and the P-47N was not ready for service until 1945, well after the P-51s were available.

There are very good reasons the P-51 was used for the long range escort mission in Europe.
