This video covers some, but not all of the specifics of the P-47 D-40 as well as some other things I haven't seen discussed before.

[@nuchbutter]

So grateful for DCS, and the P-47D module. I fly AT402s during the crop-dusting season, and when I'm spraying, I'm always pretending that I'm flying a Jug strafing Nazi convoys. DCS lets me fly my favorite WW2 bird in virtual reality...

I knew a man who owned a -47D model. He showed me how to prep it for flight and even let me start it. That was a thrill I've never forgotten. He would always say "If you want to fly a plane that excites all the girls, fly a -51. If you want to get home to your girl, fly a Jug!"

I am a Greg fanboy. And by that I don’t mean that I think Greg is the be-all and end-all, or that he’s always right. But I do find that every video like this teaches me just how much I did not know about these aircraft. For that, I am very appreciative.

[@karlbrundage7472]

In 2020 I attended the Museum of WWII Aviation and my first takeaway from the staff is that all of the aircraft there are not only flyable, but literally get flown at least yearly. I was especially intrigued to find a F3A-1 Corsair---- Built by Brewster--- in their collection. I learned, via Greg's narrative that that particular aircraft was the subject of "Blueprinting" and that it's otherwise disasterous build was being rectified by meticulous fitters and mechanics. The museum is spectacular and I recommend it to anyone remotely interested in WWII aviation. I was particularly impressed with the staff, who are all volunteer, who were very accommodating regarding photos, etc. as well as general knowledge of the exhibits. As an aside, when I introduced myself as a submariner, the staff immediately bombarded me with questions about my career and experiences underwater. I thought it a bit surreal, as I looked around at the aviation history surrounding us...............................

[@GregsAirplanesandAutomobiles]

Thanks, and that's exactly right about their Brewster Corsair. It's essentially what I would call a blueprinted airplane and is probably as good or better than any production Corsair from WW2.

[@beefgoat80]

The whole time I was growing up, I was only interested in the P-38 and the P-51. I saw the P-47 as an old cow. Now that I know more about aircraft of the era, I have a respect for the P-47 I never thought I'd have before. (Edited because I had a typo, I typed out P-39 instead of P-38)

[@SvenTviking]

Something interesting about the P38, look up how much the pilot has to do if he is flying in cruise mode and suddenly has to go to combat mode as, say, he’s been “bounced” by the enemy. Let’s say it’s about 30 seconds of switch flicking starting with turning the gun heater on. He’s dead meat. The pilots begged Lockheed to put it all on one switch, like every other manufacturer did, but they refused.

[@OuterHeaven210]

Have u ever played war thunder? It's got multiple p47 models in many different nations. The aircraft is absolutely amazing. A hot rod in the sky to be sure. After dropping ur payload u can then start climbing in order to go book n zoom. One of the few planes that earns the title "multi-role".

[@yl9154]

Mr. Greg, you are a most extraordinary communicator. I love airplanes, but I am always amazed that I can enjoy these fairly lengthy technical lectures (or series of lectures, as in the case of the p-47)! And I appreciate that you clearly, explicitly differentiate between your opinions, beliefs, speculations and facts.

[@williammorris584]

I agree. I tend to enjoy longer-firm videos on technical subjects , but even well researched and knowledgeable creators can be tedious and unenjoyable. What prevents Greg’s videos from falling in that bin is the logical progression from point to point, and the balance between terse and complete.

[@Anymouse6980]

The museum is on Peterson AFB. I used to live and work on Peterson a while back. There are aircraft inside and outside the museum. Going to the museum was a nice visit. I recommend it to everyone. There are procedures to allow civilian museum visitors to go to it on the Air Force base. Anyway, great job Greg.

[@MrFarwestt99]

I toured this museum last Saturday and was extremely impressed with their aircraft displays. What's more they are all flyable. If you go, take the tour of their facilities. The docent guides are older gentlemen, most if not all, are veterans. Johnny our guide was very well informed on history and operation of each of the aircraft. One of the most interesting, besides the P-47 is their P-38. That plane was found buried off a runway on a pacific Island. They brought it back and the museum completely rebuilt it to flyable condition in their shop. Highly recommend a visit to the museum if you are in the Colorado springs area. Also, be sure and see their immaculate Douglas AD5 Skyraider that has a cockpit for a crew of 2. The pilot escaped the fall of Saigon by flying it to Thailand. ---- He had 15 close friends also crammed on board.

[@adrianotero7963]

Is this the museum that has the internals of the P-47 on full display ? From the engine back.....all the different plumbing that it has ??

[@TheGrover1968]

I'm an aircraft mechanic by vocation. I have since childhood been fascinated with WW2 aircraft. I've been as much of a fan of the P47 and P-38 as the Mustang and have appreciated your extensive coverage of the P-47 and the blame it took for the bomber mafia's blunder. I find it interesting that in spite of the "superiority of Mustang, Corsair and others, the highest scoring American ace was a P-38 pilot.

[@lucashinch]

When I was 10 years old, I had built about a dozen or so plastic model airplanes. And ultimately each was heroically destroyed using bottle rockets plus other small fireworks leftover from the 4th. Suddenly one day, my destructive and immature behavior ceased once unpacking new model while pre-reading assembly instructions for a model of the "Hun Hunter", a historic Thunderbolt from WW2, Korea and more. It was my first high quality model with fine detail all the way down to the 2 Schrader valves within landing main gear wheel hubs. Everything about that model building experience helped me to gain an appreciation for vintage warbirds and the harrowing stories told by flight crews both up above and below. Thank you for all the time and effort you spend producing the aviation videos. The "P-47" was my first favorite prompting a serious appreciation for aviation and grows evermore. Thank you again.

[@jcarlknight]

I think the "Manual meshing control" is for using the hand-crank inertial starter. The flywheel is cranked up to speed (about 80 rpm on the hand crank) and then engaged to the engine jaw with the manual meshing control.

[@jonathanmiller8020]

Greg, fellow Tulsan and may have overlapped your visit to WWII aviation museum. They had a layout of the P-47 intercooler/turbosupercharger system of the “Jug” in a different building that gave me a new level of appreciation, thanks to your earlier videos. The plane was built around this system and it explains why the airframe is so HUGE! Thank you for all that you do!

It's nice to hear from a local. I did see the stuff in the other buildings, the museum is just amazing.

True WW II aviation fans learn to spin their eyes fast enough to read the Curtiss or Hamilton Std emblems while the engine is running. Seriously, thanks again Greg!!

[@magoid]

The dorsal fin was definitely retrofitted to earlier models, up to the D-25. The reason was loss of yaw control, probably at low speeds and max power. The tail warning radar was also retrofitted to earlier models. I know this because I read a article about the P-47 in the FAB (Brazilian Air Force) service, during and after WW2. If memory didn't fail me, the fin was retrofitted during the war (although not all units got it) and the tail radar after, in a effort to bring all the units to a common standard, equivalent to the D-40.

[@TheJustinJ]

The fin does not provide a measurable increase in area. And what few extra square feet of area it adds, it's located much closer to the centers of gravity and aerodynamics than the rest of the tail. So, it's not only too small to be effective but its leverage is also significantly hampered as well simply because its not located far enough aft to do much. To exasperate the issue, its of exceptionally low aspect ratio, and therefore its lift-curve slope (dCL/da) is going to be very shallow and develop little if any side-force at shallow side-slip angles. Therefore, it does not appear it will provide additional yaw-stability in the way you envision. It actually creates a very strong vortex-lift at extremely high sideslip angles encountered during a spin. It generates this lift by developing a strong vortical flow due to its extremely low-aspect ratio. The aft end is truncated in a sharp angle, where the vortex is shed at steep sideslip angles and that vortex more easily follows the contour of the rudder when its deflected against the sideslip. E.g. when the aircraft is in a fully developed spin to the right, nose going right, the rudder is deflected to the left to counter the spin in order to recover. But the vertical stabilizer could and likely did stall at that sideslip angle. Or at least become ineffective at creating additional side-lift by increasing camber (rudder deflection) alone. By generating a vortex flow at that juncture, the vortex cuts the vertical stabilizer in half, effectively quartering its aspect ratio, which almost doubles its stalling angle of attack. It also allows airflow to follow the contour of the deflected rudder, instead of separating. Its the phenomenon that allows the F/A-18 to attain 60*Deg AoA with an medium (4.0) Aspect Ratio wing. The F-16, various Sukhois, F-22/35 and others also use this for improved lift at high AoA.

[@kysupersport]

There is a beautiful P47 N, the first thing you see as you enter the Elgin Air Force Museum near Ft. Walton Beach, FL. Don’t miss it! My uncle flew P47’s and was shot down and thrown from his plane when he crashed. Locals secreted his body from the German’s just 17 miles from Omaha Beach. This happened late July 1944 and we still were just 17 miles inland? Scary.

I know the Pacific saw some P-47 use. Truthfully, I’d be inclined to choose the P-38 in the pacific. There were a lot of pilots lost to engine failure over water operations. Having that second engine would be at a minimum reassuring. Well… I digress from the informative video.

Interesting stuff on the P-47! When I was in the USAF; I was project officer to mount a KC-97 for the Malmstrom AFB museum in the 80's. The plane was flown in from the boneyard in AZ and made several passes down the runway before its final landing on a crystal blue day. Unfortunately, I did not have a camera for the arrival.

Alas, I have R/G color blindness, so I can’t get a license, but was a diesel mechanic and now a computer engineer, so I could have been a great plane captain or crew chief! Keep the memories flying!

[@Madkite]

Have pored over just a tiny number of the P47 plans. The complexity of these aircraft is unimaginable to most people. There must be hundreds if not thousands of drawings. Let alone thinking of making them. We forget the army of people that made it happen. The jug was also very thoroughly built. Everything was a cast aluminium or steel arm for mechanical bits. Very few pressed tin things. So nice when you can get a close look at these aircraft. That is a rare treat indeed. It's very cool to share.

[@Heatherder]

Lots of forged parts. Cast parts are brittle and poor in tension and not common outside of engine casings and other oddball shaped parts

[@BobSmith-dk8nw]

I used to play Lucas Film's _"Secret Weapons of the Luftwaffe"_ I liked the Jug and I liked the P-38. The problem with flying the P-38 - was you couldn't control the engines separately in the game. I hated the P-51. Every time I took a hit - I'd be looking at that coolant temperature - and if that needle so much as quivered - it was climb for altitude and head for home. If you had enough altitude you could glide back to Allied Lines after the engine quit - but if you didn't - you couldn't. During WWII the Germans had a phrase .... _"Die Deutsche Blick"_ which meant "The German Look". This referred to the Germans compulsive glancing over their shoulder looking for Allied Aircraft. In a P-51 I had _"Der Kühlmittel-Blick"_ or The Coolant Look ... The thing here - is that you were glancing at the coolant gauge even if you hadn't taken a coolant hit - just in case you had. What a pain in the ass. .

Hi Greg, the Hamilton Hydromatic props were installed on the D-22 and D-25 from the factory. There might have been a few loose planes with this propeller like the one with the pressurized cabin, and maybe a few converted on the field. The rest before the D-22 and after the D-25 used the Curtiss Electric props, from the skinny 12' 2" diameter prop and the two different size paddle 13" diameter props.

Thanks Greg, the P-47 has been one of my favorite WWII fighters. The constant evolution of the thing is fascinating. I realize that all aircraft went through improvements but it appeared to make leapfrog differences in the P-47 performance.

[@SoloRenegade]

especially when you consider that the XP-47 started out as part of the "Light Fighter" program and was going to use an inline engine.

[@muskepticsometimes9133]

Wow more P47 great video. I can't imagine maintaining this plane - hard enough without that complex turbo system !

[@roberthenry9319]

Absolutely awesome. Thank you. Looking forward to all to come from Greg.

[@JohnDoe-tw8es]

Thanks very much, always love anything about WW2 airplanes.

[@robertgreene821]

I just saw this video, and appreciate how hard it is to see a p-47 with turbo intact. I know you are familiar with Chris at Planes of Fame who flies one, with the supercharger for weight balance only. If you are ever in Palm Springs you must visit our Air Museum! I am a docent there on most Sundays in the European hanger where we fly two P-51s, a P-63, C-47, AT-6, a non flying P-47 and Spitifire MK IV. THe Pacific hanger has a full complement of carrier planes as well as a P-40 Would love to meet up and give you a tour!

[@hangie65]

Excellent, informative and fun-to-watch video, as always. Many thanks for posting, Greg.

[@craigpennington1251]

Do not hear dog even with headphones on. At least your output volume is up. Most aren't. 47s are my #4 in favorites. Thanks for posting some very interesting facts about this cool fighter.

[@ironteacup2569]

I really want to have an in-depth style video of the changes of each version and how the are improved or better

[@GregsAirplanesandAutomobiles]

That would be 29 versions of the D model alone, it would be a really long video

[@ironteacup2569]

@@GregsAirplanesandAutomobileslong form videos are the best. I would enjoy it all. Maybe not that deep of a dive then?

[@alexmelia8873]

Greg, you are an amazing creator and I love watching your videos on my layovers as much as you love making them on yours. Thanks so much. The technical talk makes it easy for me to sleep on these different beds as it just soothes my mind. It would be amazing to run into you at a hotel bar one night and just chat old planes. Keep up the great work! Would love to see more bigger/heavy stuff like bombers or even modern jets (757?)

[@williamscore5322]

Such a great museum/restoration facility. Went through there about 10 years ago, definitely recommend it, as well as the Peterson Air Force museum at the same time.

[@DavidSeniw]

Sir, I visited the Co Springs museum 1-2 years ago. I especially enjoyed a P-47 turbo charger that was open, on display, showing the amazing size of just this piece of hardware. As for the KC-97 restaurant, try the steak sandwich next time, you will not be disappointed. Love your work. Don't spare the sidebars, they always make connections to other topics.

[@Thuddster]

Hi Greg, Love your content! Please please please, do a piece on the A1. I know, it was technically post-war, but it's clearly the son-of-Jug, and the Spad deserves some love and exposure on your channel. The peak form of the art! Thank you.

[@sgtyork9330]

It certainly does fly. I've been blessed to watch it fly. 29 of those planes in the collection fly. Don't forget the Corsair F-3A model. The Lightening P-38F and F-7F Tigercats both fly. Yes, 2 flying F-7F Tigercats. They are planning on restoring a Razorback P-47 they have including the complete turbocharger and Pratt Witney R-2800 engine on display in one of the other hangers.

[@ethanmckinney203]

Thanks, Greg! It's amazing what you can find out by looking behind the panels of an aircraft.

[@patrickshanley4466]

Excellent presentation AGAIN

[@vvvci]

When Greg visits any Aviation museum.... the docents and museum staff tremble in fear, lol! On any topic dealing with WWII warbirds (or even more modern non-military aircraft) Greg is way more informed than they are, well, anyone besides the guys in the back restoring the old War birds. Greg could literally write a textbook or two (or three) on just about any aircraft in a museum collection... after all, do we know anyone else who quotes WWII pilot and maintenance manuals (much less for foreign aircraft) on a daily basis? On the other hand, as a lifetime warbird nerd, I cheer when Greg discovers a P-47 complete with full turbocharging plumbing leaking all over the museum floor! p.s. - I just discovered a book, "HELL HAWKS" by Robert Dorr and Thomas Jones, that claims the 356th Fighter Group of the 9th AF flying Thunderbolts out of England routinely carried 2, TWO thousand pound bombs during pre-invasion fighter-bombing missions over Normandy and France. Because many of the targets demanded low-level attack runs (like the V1 launch sites), many pilots were killed in the blast of their own bombs.

[@GregsAirplanesandAutomobiles]

Well.. they don't know me, and everyone I met at the museum was quite nice. I promise they have subject matter experts there that know more than I do at least in their respective areas of expertise.

[@leighjones5551]

What a lovely example of a P47. This was another very interesting video. Great work again. 👏

[@JM-sl9ql]

It's a great museum. Highly recommend. They have a fully functional Link trainer, with navigation map, that you can get in and "fly." Interesting restoration shop. Good exhibits. And the planes are flyable.

[@JP-su8bp]

Superb job of sharing your visit. Thank you.

[@PoochAndBoo]

Great video. One thing, though. The N model wasn't just used in the last few weeks off the war. They began operating out of Ie Shima in April of '45. Four groups were operating over Japan before the war ended. One P-47N pilot, Oscar Perdomo, became an "ace in a day" over Japan. His unit, the 507th, was also the only P-47 outfit in the Pacific to be awarded a Presidential Unit Citation.

[@GregsAirplanesandAutomobiles]

I recently made a video discussing Oscar Perdomo. You are right about the earlier use of the N.

[@terraboundmisfit]

I love your channel. Accurate info makes the difference.

[@Quick_Bisquick]

Howdy Greg! Just found your channel and noticed a very familiar airplane in the thumb nail! The P47 in the museum is one of I think 4 flying examples with a working turbo system, real useful up there at 6000ft field elevation. Another super neat and rare thing at the museum is the P38. It also has working Turbos. I have been volunteering at that museum since I was twelve so I love seeing coverage of it and glad you seemed to have a fun time! Hope you come back and do videos on some of the other unique birds!

[@GregsAirplanesandAutomobiles]

Next time, or more correctly every time I'm in Colorado Springs, I'm going there to get footage for a video. There is just so much there to talk about.

[@Quick_Bisquick]

@@GregsAirplanesandAutomobiles Exactly! They all have pretty unique stories too if you get into specifics. I would suggest the P38 or the F3A as a great next video from there!

[@GregsAirplanesandAutomobiles]

I have a lot of interest in the F3A and of course the P-38. The Tigercats are important as well for my super prop series.

[@SvenTviking]

Used to be owned by the Imperial war museum at Duxford and with those black and white chequers, it has Duxford markings.

[@acefox1]

Great video Greg! Would LOVE to see you do more walk-around detail videos like this!
