The P-51 Mustang and Fw 190 Dora 9 are surprisingly close in performance. It' surprising because the Mustang had a lot of advantages in supercharging, fuel, charge cooling, and a big edge in production quality, but the Dora comes through with displacement, RPM, MW-50 and a decent airframe.
I think just about every single article or video about the P-51 talks about how the installation of the Merlin engine turned it into a great fighter. That's not false, but there is a lot more to it, and the US contributions to the Merlin side of the story are almost never mentioned. I'll address some of that here.
The video was getting too long, which happens a lot, so I only covered speed and engine power. If the video does well, I'll make a follow up covering climb, turn performance and other factors.
Support for this channel is appreciated.

Corrections and Additions:
North Korea uses meters for altitude, I simply forgot about that country
Carb heat kills performance. I was speaking from the top of my head in general terms and not in reference to a specific fighter. For Merlin or Allison powered planes it's not really a factor. That said, fuel injected engines have an advantage in that they don't need carb heat, either as something selectable by the pilot or a source of heat that runs all the time to prevent icing.

The ONLY youtube channel (that I've ever found) that does "real" comparisons between WWII aircraft, explaining from actual period source material the actual turn rates and actual speeds at particular altitudes ext. What your analysis shows (in my opinion) is that the various planes of WWII were very evenly matched, the performance numbers are derived from various advantages, superior displacement, aerodynamic advantages, supercharger or turbocharger designs ext, but no matter how the performance is achieved the general performance characteristics of the major types of all nations was generally very similar. To me this says, its not the planes that determine the outcome of the battles, its the pilots and the tactics, the logistics and maintenance because the planes are remarkably evenly matched from a performance standpoint. The 10-1 kill ratio's aren't due to inherent advantages in plane design, they are well trained pilots in well maintained aircraft with good logistics facing poorly trained opponents with poorly maintained equipment and logistical problems. The German's had aces with 300 kills, but these men flew until they died... and their successors were never able to replicate those results because they could never be trained and prepared sufficiently. Japan had the same problem, they could never train pilots quickly enough to make up for the ones lost and so the quality of their pilots steadily eroded while the US sent Aces (25 kills) back home to train new pilots allowing the US to maintain the quality of its pilots throughout the conflict. Everybody wants to argue which plane is the best, the truth is, they were all excellent and all got better as the war progressed but it wasn't the planes that won the battles, it was the men that flew and maintained them, and the logistical support making available spare parts fuel and ammunition. Obviously I am fascinated by the technical advances in aircraft design during this period and I love the way you are able to explain how this model introduced this design innovation which changed this performance parameter in this way, shows the steady technical advances made by every nation at the time, I find it fascinating. I hope at some point you decide to talk about the P-38, I would love to know how it stacks up by the numbers given that it is so much larger than the single engine types.

@benjaminmiddaugh2729 3 года назад
The one thing you left out are numbers (unless you're including those in logistics). I don't remember seeing a graph of kill ratios versus number of aircraft being brought to bear, but by the end of the war the allies had significantly more planes and pilots to bring to bear, which would only have compounded the other advantages you've already mentioned.

A P-38 or a Tempest video would be really nice. I would also love to see a video purely based on wing shapes and designs. Like the advantages of the elliptical wing Spitfires used. Or which airfoil shapes grant which advantages like the "laminar flow" wings americans liked to use so much. And also maybe even construct the "ideal subsonic fighter wing" based on the things we have learned about it. Though that may differ based on what the plane is built for.

@James Kendrick - clarification - an "Ace" is defined as a pilot who has achieved a total of five confirmed kills in combat. Given all the risks of air combat in WWII, this is a significant accomplishment. For many reasons, there were few American aces with more than about 15 confirmed kills and they were indeed rotated back to the USA to provide instruction to new pilots, passing along lessons learned. One issue historians tend to gloss over is the tremendous danger of just flying anything in WWII, without people shooting at you. It seems like I have seen multiple fighters that suffered more losses in accidents than they did in combat. This is somewhat understandable for carrier-based aircraft, but it affected many aircraft. The Bf-109 was a bit of an "expert pilot's" aircraft with its narrow landing gear that led to many ground loops and crashes by rookie pilots - often fatal crashes. I expect the Spitfire was somewhat unforgiving with narrow track landing gear and absolutely atrocious pilot visibility on the ground until the tail wheel lifted from the runway. Simple, rugged, reliable, easy to fly were very important characteristics for reducing all of that "wastage." The B-17 checked all the boxes, but the B-24 was a real handful and suffered many fatal crashes in training and in combat. The B-26 Marauder was also quite dangerous while its bugs were worked out and the wing area increased. The F4U Corsair took so long to be made safe to fly from aircraft carriers that it spent more than a year as a land-based fighter. Your family member killed while landing after their first combat mission is just as dead as if they had been killed by flak over the target on their 20th mission. Maybe someone could really analyze the "wastage" rate on USN aircraft carriers during WWII. IIRC, it wasn't unusual for an aircraft carrier to lose about 10 percent of its aircraft per month to accidents even when not in a combat zone.

I was friendly with a WW2 P51 veteran, whose 1st mission was at 2:30am on D-Day. His group (361FG), was later attached to Patton's drive across France, so he did mostly ground attack. He told me that he wished he flew the P-47 for that kind of work. Toward the end of the war, he encountered a, "long nosed FW-190". Not sure if he went to war emergency power, but he said that FW-190D ran away from him. I have a couple more dogfights that he got into - if there is enough replies, I'll detail them here. Greg - awesome videos, really stellar. Thank you.

Sweden flew the P51B/D and DB605 engines and half of the DB605 engines where Swedish built and in peacetime conditions. So if one wants to compare the Bf109G6 vs P51D that would be a great source. They seem to both have been flown on 100/130 aviation fuel which is the regular fuel used by airlines all over the world post war. But the Swedish Mustangs should have been flown at least a short while on the equivalent of B4 fuel as Sweden used fuels in the 75-90 octane range during the war.

@@drawingboard82 I don't know that many details, but as I understand it the U.S. held a patent on the octane boosters used to raise the octane of gasoline distilled from lower quality oil stocks, which gave the U.S. a head start in developing capacity to mass produce such fuel. (It may have been Shell oil due to the influence of Jimmy Doolittle in the 1930s, but don't quote me on it.) Germany had acquired the license for the process, but their supply of suitable stocks of oil and other additives was restricted during the war. As the arsenal of democracy the U.S. was pumping the stuff out in comparatively large quantities. We know Germany had to turn to synthetic fuels, but I read they did have 100/150 octane C-3 fuel by mid war, and still managed to have 100/130 octane C-3 fuel even late in the war, but I'm guessing not in the quantity desired. More data on actual quantities could help with the picture here. Overall, I think the most significant factor in the near doubling of aero engine horsepower by the end of the war was the increase in octane that allowed use of higher manifold pressures.

I don't care what era this is from, it's a great education in the realities of engineering. While science is a study the possible and why things work, engineering is the art of application, and a study in practicality. The years from 1935 to 1946 and the evolution of the airframe and powerplant technologies is one of the best examples of the role of engineering and compromise, with necessity once again being proven the mother of invention.

@@nexpro6118 Yeah the carburetor did have some quirks that when directly compared to injection looks inferior but injection was very early tech then and the negative g effects that caused issues with the carb were sorted with the advent of the throttle body and the addition of miss shilling's orifice. Vapor locking is just as relevant with injection systems and mixture rate is infinitely adjustable with carburetor also solving your issues with adjustment when using MW50.

A while ago a couple of us asked you why the German engineers got stuck with 3 blade propellers while Americans and British jumped to four to five blades. After a bit of googling, I believe I got the answer. Turns out that not only the Germans had kept the 3 blade design, the Soviets did too. And what all of them had in common is guns firing trough the propeller arc.

German interrupter gear was top notch (actually it worked in reverse, not blocking firing, but instead firing the guns when prop was clear and firing button demand was there), and MG 131 was electrically primed = easy to control exact time of firing. 4th blade may had decreased RoF a bit, but doable.

Something I should note: my paternal grandmother's first husband (KIA 2/2/45 in Hausach while trying to make a wheels-up landing of a P-47D), 1st Lt. Albert W. "Bummy" Pines, actually did get his only aerial kill of a Focke-Wulf Fw-190 of some variant in a P-47D of the 315th Fighter Squadron ("The Crusaders"), 324th Fighter Group, 12th Air Force. We don't know what variant it was, but we do know it was not an overclaim; multiple pilots actually saw it disintegrate in the same manner as the tail was basically shot off and the port wing pitched upwards and it started something of an aerial cartwheel as it was coming apart and his old wingman, 1st Lt. Mike McGrath, who lived through 2009, I believe, was the guy whose life he saved; the Fw-190 was shooting at him and then, all of a sudden, it wasn't and he realized Bummy had gotten it. But that's not really the point. When Mike and Bummy both landed at Luneville, since they were actually flying a fighter-bomber mission against railroad targets, well, Mike was very much aware how difficult it was for a P-47D pilot who was maybe 800-1,000 feet BELOW the Fw-190 to shoot it down. So he asks him "how the hell did you do that?" Bummy, as recollected by Mike many years after the fact, admittedly, though it does match Bummy's foul mouth and laconic sense of humor: "The [bleep] if I know." Apparently, shooting down an Fw-190 of any kind was considered pretty impressive. Love a lot of the US contributions to the Merlin that you never hear about. The ultimate Packard Merlin, V-1650-9 that went into the P-51H I know you'd call a superprop, was almost "a Merlin, if American engineers had designed a Merlin", where yeah, it had more similarities than not with the Merlin 100-series, but it was its own engine. But even the V-1650-7 powering the P-51D was not a part-for-part copy of the Merlin 66, no matter how many times I've seen "oh, it was just a Merlin 66".

Your videos almost always have some information that I wasn't aware of, such as the impact of higher octane fuel on late war allied aircraft performance, or why so few WWII aircraft used turbochargers rather than superchargers (which is kind of the reverse of the automotive case). I really liked your debunking of the P-51 range myth in an earlier video. If you ever find the time (and Mrs. Greg gives you permission) I'd love to hear what you had to say about the late war Japanese and Italian fighters (e.g. the Ki-84 or the Fiat G.55). Some of these seem to have been really exceptional machines about which there is very little discussion. (I don't know if there is sufficient detailed technical documentation to do the kind of work that you usually do). Anyway, keep it up!

I personally cannot imagine the impossible task that would have been thrust upon the United Sates if the British Isles had been overrun. Of course, if that wouldn't have been a problem for you, or your interest is generally counter to the historical end result, then you are welcome to roll your dice and forever debate the proper parliamentary procedure for the sake of absolute correctness while the fire licks at your doorstep. People who are theoretical ideologues may have a hard time appreciating "time threat" and "no-time threat" protocols that many who work in the real world are taught to use every day. In a "time threat" there is wiggle room for planning before acting, but in a "no-time threat" the objective is to act before control is lost to the point that discussion becomes academic. Those of us who do our jobs based on these strategies are actually taught that one of the traps that will make failure more likely is thinking that gathering more information is always better, when in reality it can cause a paralysis from action that is far worse. Yes, there really are situations like that in world affairs, as bitter as it may be for some to accept.

In practice, this ended the arms embargo of the Neutrality Act. Of course, belligerent countries were still forbidden from taking out loans in the United States, so broader issues of finance were still an issue, but the messy politics of Lend-Lease belong properly to a separate video.

Excellent as usual, Greg.

I'm also very impressed by the combination of physics and metallurgy involved in the engine mounts for the Merlin, and for the Dora's V-12 as well. Finally, I hope you'll briefly explain in some other video (or perhaps have done so already, in which case, where?) what's involved in WW 2 propeller design. American piston-engined fighters didn't begin to go to paddle-bladed props until right at the end of the war, and even then, it's pretty uncommon to see them in photos. The F6F and F4U-4 that my Dad flew in 1944-45 all had relatively narrow prop blades. German fighters, however, especially the FW-190, seem to have adopted the paddle-bladed prop much earlier. Why? What are the advantages / disadvantages of narrow vs. wide propeller blades? My limited observations have been that few modern planes, private or commercial, use props with that sort of wide blade.

Generally speaking, a "wide" blade (the technical term is high activity factor) will have better efficiency at low speeds but worse efficiency at higher speeds than a same diameter, same number of blades low activity factor ("narrow") prop. So a wide blade may provide a bit better maximal rate of climb and maximal sustained turn performance (both achieved at moderate speeds), but may have a bit worse cruise performance and top speed.

According to Stanley Hooker in his book 'Not Much of an Engineer', (ISBN 978 1 84797 325 2), the 60 series Merlin began in 1940 when the RAF asked for a turbo supercharged Merlin to deliver 1,000 HP at 30,000' for a pressurized Wellington bomber. While RR had well developed tech and tooling for mechanically driven centrifugal compressors, they'd be starting from scratch with an exhaust turbine. However, RR had the larger Vulture motor that delivered 1,000 HP at 30,000'. Long story short, they put the Vulture's compressor in front of the compressor of the Merlin 45 (the engine in the Spitfire V) and - with the after cooler - they got the requisite 1,000 HP at 30,000'. This Merlin 60 was tested in a Wellington bomber. RR suggested the engine be tried in a Spitfire and by mid 1941 they flight tested it in a Spitfire Mk I, which led to the Spitfire IX reaching service in June 1942. By the time the Mustang was in production, Packard was already producing Merlin XXs (or the Packard equivalent) under license. Given the interest in 1942 in the way the Merlin 61 transformed the performance of the Spitfire, it was hardly a leap of imagination to wonder what would happen if you put one in a Mustang. Neither was it much of a leap to get Packard to produce it. The conversion done by RR was literally that: a conversion. It even used a prop from a Spit IX. The RAF were exploring the feasibility of converting their existing fleet of approx 600 Mustang Is to Merlins. The new North American P-51B was a re-design rather than a conversion. Thus it got a deepened fuselage, redesigned induction and cooling systems, redesigned wing root, etc etc etc. It was a major undertaking.

As I recall, tolerances of the Rolls Royce parts were too coarse and the parts usually required some degree of hand fitting before they could be installed, which was normal for Rolls Royce craftsmen. For efficient mass production Packard needed the parts to fit interchangeably without hand fitting, so they tightened the tolerances on the parts.

That's absolutely true. Rolls Royce was hand fitting the parts for every single engine. Packard improved it mainly by using modern production techniques.

Rolls Royce was capable of manufacture to tight tolerances, they just did not see the point as they had the skilled trades to sort and fit the parts which best matched.

The next chapter in the story, after being told by Packard the existing plans are not precise enough, is actually pretty funny. Instead of redrawing the plans, Rolls Royce simply shipped an entire Merlin engine to Detroit. Which worked, but was also a bit passive aggressive.

The P-51 D had was a vary different airplane than the earlier models. The "bubble" canopy is the most obvious but they also had greater affective virtical fin area , and thicker wings to house the browning M2 machine guns in it's "normal" position. I have read of complaints from pilots saying the the "D" model had "leaky" fire wall seals that made them vary hot at low levels and just no longer "fun" to fly.

I think it all comes down to the pilot and the specifics of the situation. Each plane has certain situational advantages which can be utilized against the other by a skilled pilot. Either way, two of the loveliest combat aircraft to ever grace the sky.
