The Curtis P-40 was built with both the Allison V-1710 and the Packard Merlin V-1650. Why did they build it with both engines? Which was better?
I'll cover both engines as used in various models including the E, K, F, L, M, and N. The F and L models are Merlin powered.

Greg…I’ve been an amateur WW2 historian since the third grade (I’m 62…hard to believe) and I must say, when it comes to explaining the aircraft of this period, you are so far ahead of the pack that no one else even comes close. Your videos are so crammed with technical facts and minutiae that I have to re-watch them several times to fully get everything you are throwing at me. It’s a real pleasure to watch/listen to your amazing shows. You effortlessly explain the differences in mechanical engineering as well as the flight characteristics of each aircraft. It has really fleshed out my understanding of the air war…far more than any dozen books on the subject could have…in my humble opinion. Thank you for your generosity in sharing your expertise and keep up the good work.

My fathers friend " Rusty " flew P-40's in North Africa. When I was about 12-13 yrs. old I asked him about his service . I had been reading all about the various WW2 campaigns and was eager to hear a first hand account. His refusal to talk about the war brought home to my adolescent mind that war was not glamorous and something a person may want to forget they had ever been involved in. His one concession was he told me the P-40 would dive like a streamlined brick.

Exactly, it was carnage. The short tailed P-40s were a handful, needing constant trimming with changes in speed. Dives required a lot of effort and leg strength. Two point landings were preferred due to low speed instability. Roll rate was effective though. The key was to be able to see the 109's before they pounced from above. Teamwork in finger four formation was critical. So was the fact that they outnumbered the LW by mid-late 1942.

I had a relative who flew P40's in North Africa against BF 109's. He said they were competitive and he had two victories before being shot down. His engine took a flak hit and 3 German 109's were trying to claim him as a kill as he was glidiin for a landing. He said the three each took passes at him which he avoided by faking a turn and then reversing it once they committed. He was so slow with a seized engine that they were overshooting him on their gun runs. After doing a wheels up in the desert, he was strafed by one and was badly wounded through both legs and had some eye damage from splinters. He considered them strafing a downed pilot as very poor form. He was in an ambulance on bad roads from North Africa all the way to South Africa apparently. He flew ferry missions to front line bases after that, as he was not cleared for combat.

I used to give tours and talks on the P-40 we had back at a local Museum years back and have always had a large respect and affirmation for this aircraft. We had a P-40N-30 produced in 1944, at which point the P-40s were carrying a bombload of comparable size to the much larger P-47s. Very underrated airframe in my opinion and I am glad to see a video from Greg of all people discussing some subject on it. I certainly look forward to anymore videos on the P-40 in any capacity, and if you ever do need some P-40L documentation I have some old scans of archival material that may prove to be useful.

Most effective against ground troops in China was six 250 pound fragmentation bombs that had segmented casings like a pineapple grenade, about a 10 foot detonator-probe sticking out the forward end, conventional fins but also a drogue chute on back. A vicious vicious load of antipersonnel ordnance. The only living things that I could ever justify using such hellish weapons on were The Communists. And so they were.

One pilot stated who had flown both the P-40 and the P-51 said he could at below 10,000 ft he could turn inside a P-51 with the P-40. If not for the lack of tungsten, the P-40 would have received a two stage supercharger, but this wasn't considered a drawback as the USAAC as the bomber mafia beliefed that bombers would get through (although the P-38 should have shaken that idea) based on speed. Both the P-40 and P-39 (the build two designs in case on turned out to be a turkey), were considered as to counter West Coast invasion as ground attack fighters as Japan was thought to be the invasion threat of an enemy. This was one reason for the heavier pilot protection for the P-39 and P-40.

I also know that the later P-40Ns did carry rockets, namely the 4.5" M8 rockets, but I do not know of any instances where this maximum bombload and rockets were carried together--especially since the M8 rockets were a rarity in P-40 armaments.

One thing about the Allison is that it is a modular design. It's cam gearbox and power takeoff could be bolted to either end. IIRC, it could run clockwise or counterclockwise. It was envisioned and engineered to be as versatile as possible. And strong. The Mustangs that race at Reno use Allison conrods in their Merlins because they're stronger.

Your graph at 18:12 with the 109F included is probably the key reason for the p40F. As I understand the fighting in the Mediterranean early on was particularly fierce. The attrition had yet to impact the Luftwaffe and they still had many aces in the ranks. The 109F's would frequently pounce from above and maintain an energy advantage hence the need for something to reach them. Thanks for the upload!

Thanks Greg. Yeah, I believe the P-40 got a lot of it's bad mouthing from being used in Northern Europe where they flew at higher altitudes. Where they flew mostly at lower altitudes it was more highly regarded. One thing about New Guinea - was that while the Betty had a very high altitude - the Japanese didn't have a lot of choice about the altitude they were flying at if we were attacking their air fields. Here - as I tend to mention when talking about P-40's and F4F's - these two aircraft took on the cream of Japanese Naval Aviation and fought them to a stand still. Later aircraft were taking on enemies of a less denser experience base - because of all their veterans who died at the hands of someone in a P-40 or F4F. P-40's also saw extensive service North Africa - which is where the Flying Tigers got the idea for the Shark Nose the P-40 is such a natural for. .

I agree that F4Fs took the cream of the IJN in the early war, but I’m not so sure about the P-40. I think the P-40 (and P-39) held their own against the the Japanese so long as they strictly held to fights below 15K feet and didn’t turnfight, but it was standard practice for Japanese to come down on P-40s and ‘39s from above 18K feet. It wasn’t until the F4Us and P-38s (Guadalcanal) came on the scene that the tables really turned on the Japanese Air Force. P-38s and F4Us had the altitude and speed to dictate terms of engagements. Also, there are records of a number of engagements between P-38s and Japanese above 20K feet - it wasn’t the norm but it certainly happened more than a few times.

Thanks Greg another great dive into the details! My dad was an engineer at Curtis during the war and was especially proud of the P-40 because of the in his words "the constant improvement process" he told me about a giant chalk board the was on the factory wall and how they charted the various parts and the improvements of that part during the entire build cycle of the P-40, he said "our boys deserve the best" and we are bound and determined to give them what they need. He was very proud of his war effort, even though very little ever gets mentioned of the thousands and thousands of "slide rule geeks of the day" he and other engineers/draftsman often slept under their drafting tables for a "few hours at a time" then back to work. He said "it was the most exciting and exhausting time to be and engineer" as they sometimes would make an improvement to a part and have it ready to be installed on the plane the next day!!!

Thanks for mentioning Australian P40s. As I'm a Real Baby Boomer, the war was fresh in everyone's minds when I was small, and I think I knew about RAAF P40s even before I knew about Spitfires, though they were retired before I turned 2, so I don't recall seeing any. We were often behind the door when military aircraft were being given out, but managed to achieve quite a bit with the less spectacular but still effective aircraft like the Kittyhawk and the Beaufighter. Even the Boomerang, while not a great threat to enemy aircraft did at least frighten bombers off and prove effective in ground attack and pathfinder use -- and wasn't a bad achievement for an almost non-existent industry.

It in no small way help save Port Moresby. The Japanese went from offence to defence at this place. Here in AUS the mighty "Kitty Hawk" is a revered aeroplane. There is at least one still flying.

Thanks for this interesting discussion. I know that some earlier scholars have called the P-51-B, basically, a P-40 that "Dutch" Kindleberger pulled out of a hat, when he shifted from working for Curtiss to working for North American. [And, in association with that: both the P-51-B and the P-40 were notable, mostly, for their operations at lower altitudes.] Your commentary tends to show that, although the P-40 in all its variants proved to be a [DAMN!] useful aircraft type, everywhere from the deserts of Northern Africa to the aerial "winter war" over the Aleutian Islands, and especially in the hands of Aussie and Kiwi pilots in the South Pacific, it nevertheless, whether fitted with a Merlin or an Allison engine, was never a high-altitude competitor. So, if that sort of high-altitude performance is in fact the measure of an aircraft design, then: the P-40 never made it. But, that raises the question: if an aircraft type is so darn good, and reliable, in delivering its mission at lower altitudes, then doesn't it deserve some aviation "stardom" from that? And with that analysis, rather like the ground-attack versions of the Hawker Hurricane that were used so successfully in North Africa (as well as doing most of the heavy lifting in the Battle of Britain while the Spitfires were doing their celebrity performances at higher altitudes), the various variants of the Curtiss P-40 did a damn good job, at the altitudes at which they were effective. [And, good air leaders learned to train pilots to operate them in those effective altitudes, and not those in which they performed less well. Perhaps the classic example of leaders training pilots how to use the P-40 to do what it did well (and not try to do what it didn't do well) remaining General Claire Chennault, leader of the American Volunteer Group (better known as "the Flying Tigers," over China, when there was little defending China against Japanese aggression in the air.] Anyway, let's hear it for the P-40, in all its many manifestations, and what it accomplished for deterring Axis aggression, before all the famous, wonderful, and revered later aircraft types appeared on the scene and overshadowed the good old P-40. [Similarly, I'll note, to the tough, rugged Grumman F-4-F Wildcat, which did an honest job of confronting Japanese aggression in the Pacific Theater before more modern aircraft types were introduced to totally outclass most of what Japan could produce during the Second World War in the Pacific.]

A really good presentation as always. In Europe the RAF found that most air combat with the Luftwaffe was at higher altitudes, 20,000 to 25,000 feet. Were unfortunately the P-40 was considerably slower than the Me109E/F models. It was the same story with the early P-51s, which were very fast at low level but lost its edge at higher altitudes.

"The initial Packard modifications were done on this engine by changing the main bearings from a copper lead alloy to a silver lead combination and featured indium plating. This had been developed by General Motors' Pontiac Division to prevent corrosion which was possible with lubricating oils that were used at that time. The bearing coating also improved break-in and load carrying ability of the surface. British engineering staff assigned to Packard were astonished at the suggestion but after tear down inspections on rigidly tested engines were convinced the new design offered a decided improvement."

But after that Rolls-Royce engineers went to work and developed their own bearing materials that were even better than what GM had done.

Anyone who has tried to use a 1/2" Whitworth spanner on a 1/2" SAE nut has failed miserably. It would have been easy to mix up different standard tools, and a pain to have to have both tool kits.

Always loved the P-40. My dad flew a Mustang once in IA back in the 60's. I read there are various supply ships that were sunk with new P40's in crates, 1 near a Japanese port not extremly deep. I learned to scuba-dive in Hawaii working on F-4J's (VMFA-232) and have always had a notion of trying to find one and recover it. If I ever win megabucks I may try, would take up to Greenville ME airport my family started and rebuild/hangar it :)

I think the P-40 is a clear example of "judging a book only by it's ending" in aviation/military technology. It seems the P-40 was a quite worthwhile concept in itself, just didn't receive the development that it's closest competitor P-51 got, and was then judged as "not competitive in 1945 - must have been a worse concept". To change perspective: It's a bit as if the Germans had stopped development of the Bf109 past, say, early G-variants.

The P-51 design team was much superior to the Curtiss team and took years to develop. Edgar Schmüd had been playing with his new fighter concept since Meredith published his paper on radiator cooling drag in 1935. Jacobs at NACA had been chasing low drag airfoils since 1929 and NAA Ed Horky, who extrapolated a wing from that, had studied aerodynamics/boundary layer at CalTech under Theodore von Kármán, Millikan and others on the leading edge (so to speak) of boundary layer science. It wasn't until early 1943 that the Mustang evolved into a superior fighter as the P-51B. By contrast, the Curtiss team took a P-36 and plopped an Allison out front with much indecision over cooling drag.

@@bobsakamanos4469 Well, put like that I'm sure you have a very good point, and especially the aerodynamic concept of the P-40 was propably outdated in comparison. It still very much reminds me of the Bf-109's position - a small, nimble, pre-war design facing obsolescence in around 1942. In the latter case, they stuck with it (due to manufacturing concerns, and Willy Messerschmidt quite masterfully using his influence within the RLM), even though other designs were arguable way more capable. Though the Luftwaffe was facing a different problem, and of course the long range bomber escort role that became it's main concern in Europe was where the P-51 made most sense.

A tribute to the effectiveness of the original design, although Willie was of course involved in other advanced aircraft (Me262, 210, 410, 209, etc), not just the 109. Incredible despite the increasing shortages of strategic materials and bombings. By contrast, the P-40 was a cash cow without much development. Sadly, they started with the rad in the right place (belly mounted), but did not improve the ducting IAW the Merredith effect. However, I did like their effort on the XP-42 stabilator.

Gain altitude, high speed pass through, and if you didn't knock the aircraft down... peel out and gain altitude for another high speed pass. THAT was the P-40's advantage. He also made the lead - wingman formation the bible of air combat. The morons in charge of the Army Air Force and the Navy ignored his advise for way too long, wasting many many fighter pilots and aircraft. Once his tactics were incorporated as standard practice... the F4F had MUCH better results as well. And, even the P-38 was limited to high speed pass through. It make common sense... which is why it took so long for the brass to finally "get" it.

At the time of the merger, Wright mainly built engines while Curtis built both. The key is that Curtis built liquid-cooled V-12s while Wright built air-cooled radials. So the air-cooled radials called are called Wrights. I work as a software engineer in Avionics. Last month I was reviewing spec sheets for some SBCs made by Curtis Wright which I admit is very cool. I do agree that the P-40 is kind of underrated much like the Hurricane. Now here is one thing I have wondered about for a while is since the P-40 was based on the P-36 why didn't Curtis Wright build a version of the P-40 with the R-2600? Could have been a very good ground attack machine.

Very interesting video regarding the P-40 with the Allison V-1710 engines and the Packard/Merlin. First of all the P-40 was an excellent fighter and was very tough that could stand a lot of punishment! I knew that the Allison V-1710 had better performance and more powerful than the Packard/Merlin at lower altitude whilst the Packard/Merlin had better performance at high altitude but I didn't know that the choice of engines was due to the logistics in the respective countries: the Allison V-1710 was preferred by the Americans and the Packard/Merlin by the British and the Commonwealth forces. It makes sense because the US knew well about their engines and the British and Commonwealth had better knowledge of the Packard/Merlin, that said, I read a book that said that the Allison V-1710 was easier to work on and to maintain then the Packard/Merlin. Good job again and looking forward to see your new videos 👍👍👍

The altitude power characteristics depended on what the supercharger was set for. There were low, medium and high blown engines. Spitfires, say a MkIX came in HF (high altitude) FR (medium high) and LF (low altitude) versions, the latter normally with clipped wings to improve roll rate. The Merlin 70 series was very high blown for high altitude reconnaissance.

Great video. Very well researched and presented. The Allison suffered from a lack of development related to supercharging before the war. The US Army Air Corps policy was to prioritize turbocharging over supercharging due to the parasitic drag of supercharging. Two stage supercharging gave the Merlin 60 and beyond outstanding high altitude performance. Running a two stage blower requires careful engineering in order avoid detonation issues. Intercoolers and methanol injection are some of the ways engineers tried to address detonation issues. Due to a lack of funding for R&D from the the USAAC, the Allison was not developed with two stage supercharging. The Merlin was developed this way, so Rolls Royce was way ahead. The Allison was still a quality product; well engineered, modular, robust, and easily adapted to many different applications. The V1710 story is an interesting one, well worth reading about.

I was lucky enough to see the P40 (I think there is only one flying in the UK) at a small ex WW2 airfield, Wellesbourne, Warwickshire, a couple of years ago. There is a small café, The Touchdown Cafe, on the airfield open to the public. It has an outside seating area where you have an excellent view of the light airplanes. I was sitting there having a coffee, looking at the P40, only 20m away, when a guy in a leather jacket, who was two tables away, gets up and goes through the gate to the P40, puts on his leather helmet, climbs in, starts up the engine and warms up, giving plenty of time for photos. He gives a wave and taxies out and takes off. You don't get chances to see that sort of thing so close that often! Brilliant! While I'm here, I'll give a plug to the Touchdown cafe. Well worth a visit. Look it up. The airfield itself is in danger of being developed into a housing estate which would be a damn shame. I only pop over every once in a while, but it is always fun.

Ok Greg, A little post WWII Detroit engine history. My father moved to Detroit in 1947, as a job transfer. Bring his sports car with him. A 1936 Cord with the straight 12. Well he needed a mechanic, the one he found was building race boats for the Detroit river races. He was running sur plus V12 Allison's. My father always thought he was running Allison's because at time they were very inexpensive, now you have informed me different. One of the things that always struck me, when we talked about it(I was maybe 12 and not able to understand all, but still knowing there was much missing info from my father.). He said(my father) that he was running the engines on a homemade test stand, to over rev and holding it till the piston rods would stretched and blowing the heads. Now with that info, and your video I understand why he was doing so. And am very sure that Allison's engines were doing very well in the use of race boats. Keep in mind we are talking 1946-1949 My mother and father married in 1948, and I know he did not keep the Cord long after moving to Detroit.

The Columbus, Ohio plant had its own design dept. and aircraft designed and manufactured there could be named as "Curtiss-Wright" aircraft, hence the "Curtiss-Wright CW-21 Interceptor" and the two-seater CW-22 using the same basic design. I can't say why this is so. The plant also played a primary role in the development and production of the Curtiss SB2C Helldiver, so go figure as they say. As to the use of "Curtiss" for aircraft, the name was well-known for seaplanes during WWI, as well as many other earlier Glenn Curtiss aircraft designs. He was famous for both engines and early airframes.

Caught this last night and like everything you produce it was fantastic! I don't know anywhere else one can go to to get an in depth discussion on subjects such as Wildcat superchargers, the plumbing of P-47s and the effects of octane on German fighters. Only here and thanks. The P-40 has always fascinated me and, since I was a kid, I have wondered how the Merlin engine stacked up against the Allison in the P-40 airframe. Obviously, the Merlin wasn't a magic bullet as the P-51 story would have us believe. On the subject of the P-40, I would like to hear a discussion on its predecessor, the P-36, and how that plane might have faired against the Zero had we pursued a more simpler modification of the airframe with a more powerful radial engine and not the Allison as in some ways the Hawk was a better plane and one that might have held its own against the Zero if the pilots made the Japanese pilots fight their fight like the latter often did with the P-40. Thanks again for your great videos. They do an airplane junky's soul good.

love the content on one of the "less glamorous" fighters of WW2. Would also love to hear more on the P-39, especially in Soviet use. The "less armour" comment on the P-40N sounds like a scary refinement for a pilot. the comments about running 70 inch pressure reducing engine life, my response would be that it probably prolonged pilot lives. It takes much less time to build an engine than to grow and train a pilot.

The more I read about fighters of the early years, the more clear it becomes that the most important single factor in the success or failure of any fighter was the familiarity of its pilots with the machine's strengths and shortcomings, and with the tactics and capabilities of their adversaries. A quote from a P-40N pilot in South China, Captain John Herbst: “Our boys had been flying on the deck for so long-strafing and dodging hills in bad weather-that nobody thought twice about racking around in vertical banks ten feet off the deck. It was just our ‘meat’.”

+ Flecto Varathane I think post-war comparison testing of captured examples of the late-war 3rd generation fighters had the same conclusions. The advantage depended on the skill of the pilot knowing his aircraft and the opponent's aircraft.

Thanks Greg, I've always wondered what the differences were besides the supercharging, and the fuel efficiency. I seen a video recently about the Messerspit. I wonder if you would conciser doing a video on that plane. I thought it was and interesting concept, and a small piece of history vary few are aware of.

The P-40 was a good fighter within its limitations. Pilots who flew it learned to use its strengths in combat. I had an aviation mechanic explain the differences between the Allison and Merlin engines, which are similar in many ways. The Allison is much more simply laid out with nearly everything easy to get to. The Merlins were/are like a complicated jigsaw puzzle and much more difficult to maintain. He pointed out that for every hour spent on an Allison, it would take six to eight on a Merlin. However, the turbo-supercharger system designed for the Merlin was smaller and easier to maintain than the one for the Allison. The P-40 was well employed by the British and the Commonwealth countries. The top P-40 ace was Australian Clive Caldwell, who shot down 22 Italian and German aircraft over North Africa while flying P-40s.

@@nabirasch5169 If you look at the two engines side by side, it's easy to see that the Merlin is the more complicated of the two. This video versus people who work on the two engines currently . . . the fact of the matter is the Merlins are down more often than the Allisons. Then from histories I've read, it's clear that the Merlins required more TLC than the Allisons. After WWII when boat racing became popular in America, there were thousands of both Merlins and Allisons available as power plants. The Allisons became the most popular because they were easier to maintain and they didn't breakdown as often. This is not to say the Merlin wasn't a great engine, not by any means. It does mean though, that the engine requires much more maintenance to keep it operational.

Greg… I just plagiarized this from the guy below, but it IS exactly how I feel! Sorry Christopher Pabsst! Sincerely! I’ve been an amateur WW2 historian since before the second grade my uncle was a p-38 ace in the PTO! (I’m 74…hard to believe) and I must say, when it comes to explaining the aircraft of this period, you are so far ahead of the pack that no one else even comes close. Your videos are so crammed with technical facts and minutiae that I have to re-watch them several times to fully get everything you are throwing at me. It’s a real pleasure to watch/listen to your amazing shows. You effortlessly explain the differences in mechanical engineering as well as the flight characteristics of each aircraft. It has really fleshed out my understanding of the air war…far more than any dozen books on the subject could have…in my humble opinion. Thank you for your generosity in sharing your expertise and keep up the good work. PS. Your work on Boyd is great! Should apply it to the Spit-Vs-??? argument! Those Spity guys just don't get the idea.

The Allison V12 became a favorite of tractor pullers in the 70's and 80's and were cranked up as much ad 2,500 HP, with turbos and fuel injection while running on alcohol. They proved to be quite reliable but these are short duration events rather than prolonged cruises and dogfights.

I remember reading that the engines that were used for the Flying Tigers were factory rejects, that Chennault had a team of engineers rework to functional condition. These ‘Blueprinted Engines’ were hand fitted and machined to work properly, and while this was very labor and man-hour intensive, it resulted in engines with a much tighter tolerances and as a result, were rated for much higher power output
