The Supermarine Seafire 47 was one of the earliest Superprops, it wasn't the best British Superprop, in fact it wasn't even the best Superprop from Supermarine, but it's a beautiful plane with great performance and some interesting technical features.
A large portion of this video covers the Rolls Royce Griffon series of engines.

Note: A couple errors I need correct.
1. It was the FRENCH Navy, Not the British Navy that replaced all Seafires with Hellcats in 1950. In regards to the British Navy, Seafire 47's were operating from HMS Triumph. These didn't hold up and when she returned to England the Seafires were replaced with Boulton Paul Balliols because she went into use for cadet training.
2. Yes, the Mk8 came out after the Mk9. The point is that every Spitfire I know of in numerical order after the 8 has the earlier type of non self sealing fuel tank. These include the 9, 11, 16, 19, 21, 22, and 24. As some of these are post Mk8, Supermarine went "back" to the earlier non self sealing design. In regards to the Mk9, yes it came out before the 8, but I'm not sure when the design work started on the 8 vs. the 9. In any case, the most numerous marks have non self sealing upper tanks.
3. The wing on the Seafire 47 is not "the same" as the early Spitfire model, nor did I say that in the video. Obviously it's different. As mentioned in the video it has a folding mechanism and the entire structure is beefed up relative to early airplanes. However the wing areas of the Seafire 47 and early Spitfires are within ONE percent of each other. The wingspans are within ONE inch. The wing profiles are EXACTLY the same NACA numbers for the main section and the tips. All this stuff is the same, yet the weight of the plane doubled.

I was in Hong Kong in 1949 and the RAF was flying "Spits", probably Mk 24's. They'd to go up and dog fight several times a week, there wasn't much traffic at KaiTak airport so they had the skies to themselves. Several were WW2 aces who'd square off against about 8 or 10 younger pilots and teach them dog fighting. It was the best display of air-to-air combat you could ask for, the aces would make these amazing maneuvers, they'd roll and twist around, stand on their wing tips in tight turns, the most experienced pilots would make these high speed dives right down to the deck, pulling up at the last minute. It would've been great if we had modern digital cameras, or even phones, so we could take videos of these guys. Some of them had red spinners on their noses which looked really great, it was the show of a lifetime.

@20chocsaday 2 года назад

Dogfighting was one of the topics covered in an interview around the time of the first use of of the STOL Harriers. I think they were being deployed to W. Germany at the time. The [man from the ministry] was asked why we should want such slow aircraft anyway, apart from the fact that they could take off from the middle of the forest. His reply about the low (not supersonic) performance was that, If it ever did come to dogfighting, experience has shown that speeds rapidly drop below 300 miles per hour.

A video on the Spitfire 22/24 would be stellar. Two extremely capable (admittedly nearly identical, aside from the fuel systems, elevators and guns/stores) machines with almost none of the downsides of the earlier Griffon Spitfires. 390 mph at sea level, 454 at 19,000 feet, and a rate of climb of 5,100 ft/min with the Griffon 64! The Spit 24 with the Griffon 64, 223 gallons of internal fuel, Hispano Mk Vs with 650 rounds, 8 rockets, spring tab elevators, blistering performance and superb handling would have been a real asset had it appeared earlier. The revised stiffer wing with the bigger tabbed ailerons, better landing gear, etc. of the Spit 21-24 (and thence Seafire 45-47) hasn't really been covered in depth anywhere and I'm almost tempted to do a video on it myself.

⁠@@user-kz7gi4tc5lyea I wasn’t too sure about that either. My great grandfather found out about how he had died from another pilot called J S B Reynolds. He was another Flying Officer and served in the same squadron. There is even a photo of him and Bruce reading a map together. Apparently what had happened was, the pair had just touched down and began taxiing to get off the runway when they were told via radio to get off as another spitfire that had suffered damage had to do an emergency landing. Reynolds managed to manoeuvre off but Bruce seemed unaware as he didn’t manoeuvre. The damaged Spitfire unfortunately landed on top of him, instantly killing him. We believe he took off his headset once he had landed and simply didn’t hear the control tower telling him. If you visit the IWM Photos and search ‘Italy January 1944’ you can see most of the photos🙂

@WarblesOnALot 2 года назад

G'day, They're a Rectangular Prism shaped, or (Hemi)Cylindrical, Flexible Bag, or Fuel-Cell ; the Walls of the Bag are a Sandwich comprising outer layers of Vulcanised (Sulphur and Heat- treated "Cured") Rubber Fabric which were Fuelproof..., with a 1/2-inch layer of Raw Latex between the inner and outer Layers. Raw Latex reacts chemically to exposure to Petrol by coagulating and congealing into a Jelly-like Paste So...in an ideal world, the Projectile punches a neat round hole in the Wall of the Bag, the Liquid Petrol cops the Ballistic Energy, the flexible Bag contains the Hydrodynamic Shock by ballooning and transfering the Wave-Energy to the surrounding Wing/Fuselage structure..., so the Projectjle is stuck inside the Fuel, with not enough Air to have enough Oxygen to ignite - even if it was a Tracer or an Incendiary Round. Then the Raw Latex between the layers of the Bag Walls oozes accross the Entry/Exit Wounds, and the Petrol coagulates the Latex in the Hole through the outer Layers, thus plugging the Hole/s. Not perfectly "self-sealing", but a hell of a lot better than having a burst if Gunfire rip through a basic Sheetmetal Box - like one would find in a Sopwith Camel or a Mitsubishi Zero... Once it had been holed, the Self Sealing Tank had to be pulled out and replaced..., and they were heavier than sheetmetal ; but the Self Sealing Tanks prevented a LOT of Aerial Fireballs. Until 20mm Auto-Cannons were fitted to Aircraft, and blew holes in the Tank Walls and Seams too big for the Latex to plug. They don't call the phenomenon an "Arms Race" for nothin' (!).

The Spitfire cemented her legacy very early on by the pilots who flew it, the enemy who feared & respected it, the ground crew who serviced it, & the general public who fell in love with it... Its a legacy that exists to this day, & quite rightly so.

Years ago i had a lovely evening with Jeffrey Quill about the Spit and the different marks. we both agreed that the Mk IX was the best Spit in its handling qualities. He said thad that the balanced feel was destroyed with the Griffon. He also said that the plane started to become more of a handful. the Merlin powered planes handled the way " RJ designed it to handle". Jeffrey said he and "Mutt" Summers were in constant talks about the Griffoned powered Spits. what was noticed in own conversations was his referring the Merlin powered Spit as" her or she "yet the Griffoned powered Spit turned into " it's". he delighted in the earlier Marks and the constant work to improve the earlier Spits. he remarked that the Fw190 caught them off their feet hence the Mk 5a. Well just a little tidbit from those that Ive met over the years.

A very interesting and comprehensive film. It's a amazing that Joe Smith and his team at Supermarine were able to keep the design compitetive with its contemporaries considering the age of the basic design and that the aircraft was never designed for carrier use. I have just one issue which is that you state that the Seafire F.47 was replaced by the Hellcat after its operations in Korea. This is definitely not the case. The last lend-lease Hellcats had been disposed of some years before. The replacement for the Seafire, both in Korea and generally, was the Sea Fury FB.11. In fact the Seafire F.47 was only ever an interim aircraft until the introduction of the Sea Fury, hence its small production run.

@tonym480 2 года назад

Interesting comment toward the end of the video Greg, regarding skin wrinkling on the Seafire. Years ago now I worked for someone who had been an airframe fitter on HMS Indomitable when she was with the Royal Navy Pacific Fleet toward the end of WW2, and one of the things he mentioned was having to inspect the earlier Merlin engine model Seafires for skin wrinkling, especially after they had been carrying out diving attacks against ground targets. Being quite a small man he used to get the job of climbing around inside the fuselage to check for damage to the internal structure, a job he unsurprisingly disliked.

@stephenconnolly3018 2 года назад

He claimed the wrinkling was due hard deck landing. There was too many factual errors and gaps in his knowledge. It is Called the Dunning Kruger effect

@nexpro6118 Год назад

It wasn't really widely known at the time that if you keeped constant maintenance on the airframe and wings to keep it as smooth and clean as possible, that it would GREATLY help with aerodynamics and drag. Helped drag, massively!!! The Germans were even worse at this than the US, especially since the Germans were having to manufacture aircraft in wartime conditions and areas. Its why the late variant, P-51s like the, D variant because they discovered to keep the fighter as clean and smooth as possible.

The marks VII and VIII were re-engineered as the definitive Merlin spitfire, but were pre-empted by the success of the mark IX and it's Packard engined alternative, the mark XVI.

It wasnt until late in the war, like in, 1943 time frame that it was finally discovered that if you make the aircraft as slick, clean and smooth as possible, that it helps reduce drag by a shit ton!!! Which obviously means that even if a US Fighter had less HP than a German Fighter by about 100-200HP, the less drag from the US Fighter would make up that 100-200HP lose. It helped the US, especially with the P-51D variant with a smaller engine/displacement and with higher octane fuel and smoother airframe that made the, P-51D the best/superior Fighter during the war. Unfortunately it didn't come until very late 1943 and wasn't used in big numbers until 1944 towards the end of the war. Imagine if the, P-51D variant was in mass numbers in 1941......

No unit replaced late model Seafires, either 45s or 47s, with Hellcats (that certainly happened in the Second World War): 800 NAS switched to Attackers, 802 to Sea Furies, and 812 to Fireflies.

The British gave Mr Smith a hard tie about his replica Stonehenge, which is made of white limestone. He simply said I it will be fine and a good replica, just wait several 1000 years and it will be weather dark like the original! 😎 Oh, he was going to paint it camo, like many of the WWII regular Spitfires, but the British were having kittens over that color scheme, so volunteered to pay for the Navy colors and insignias to keep the plane like the original configuration and historically correct.

Great episode, Greg. You've made an old British patriot misty eyed for the glory days.

@michaelmagill189 2 года назад

My opinion may be a bit jaded but riding in the back of a P38 going 400 mph at 50 feet off the Mojave Desert with the infamous Fish Salmon at 10 years old tends to do that. That said, I do like Cessna's and am fascinated by all things aviation. I like that you, Greg, discuss the good, bad and ugly. Without comparison one has no basis of judgment and you provide that baseline. Keep the vids coming and I'll damn sure keep watching

@wkelly3053 2 года назад

One of the best yet. I did like what seemed to be a bit more talk about the heritage of the airplane, specifically the progression of the fuel system, and not quite so much on interpretation of graphs. Nothing against graphs and charts, just a good balance here. Thanks!

Hi Greg, oh I did enjoy this video and this particular series of "Super Props". As stated, these were the pinnacle of piston powered fighter aircraft development and hold a special place in aviation history. Once again your focus and dedication to the facts make the story accurate and objective. Cannot wait for the upcoming videos. In particular, although I have many favorites, the mighty Sea Fury is the one I'm holding out for the most. BTW, I thought the Sea Fury, not the Hellcat, replaced the Seafire? Thanks again Greg. Keep up the great work, it's much appreciated and enjoyed.

@neildonaldson3408 2 года назад

It is interesting that there was only one other follow up to the Seafire 47. Perhaps the Seafang may be covered within the Superprop goup. End of the line? Surely, but it would be good to see the comparisons between all these later types. Well done Greg. An excellent piece. Thank you.

Hi Sir, thank you once more for sharing your searches and knowledge! You can see a very good job when even the subject is not expectacular in interest wise at least for me like this particular plane, the Seafighter, but you keep stuck in front of the screen and can't let it go!! To give you an idea of it, yesterday I was watching this video late night hours and I was dead sleeping, half of it I couldn't stand my eyes open anymore and I quit! Today in the morning the first thing I did after my breakfast was to come back again and watch it properly!! Good job!

...and here I was thinking that the extra blades were because there was surplus and manufacturers were getting them at a serious discount. 😁 On a serious note, I love your videos. Things like the "breakaway wingtips" of the Bearcat are real eye-openers. As well, your discussions on flight performance and the realistic evaluations are something that anyone who is interested in powered needs to see.

@Pete-tq6in 2 года назад

I enjoyed this one, a very fair and balanced assessment. The Seafire 47's subsequent carrier prop aircraft, the Seafang (based on the Spiteful), couldn't dive as fast as the Seafire 47 and its laminar flow wing didn't offer the benefits that were promised. After the Spiteful, Supermarine attempted to use the wing on their first jet - The Attacker, which wasn't a particularly illustrious machine either. The Spitfire really was Supermarine's masterpiece. Reginald J Mitchell was a great designer who died too young, had he lived longer it would have been interesting to see what he could have developed.

Great video once again, Greg; thanks. I was fortunate enough to stumble across a documentary I had watched years ago, and I'm sure you have seen it. "History of Formula 1 and Formula One". Apart from the apparent car stuff I know you enjoy, there was a great reference to the de Havilland DH 106 Comet (1:20:10) and its and other aircraft's influence that continues to this day in F1 and all kinds of motorsport activities. A little off-topic from your video, I apologize, but I had to put pen to paper, so to speak, before I forgot! Have a great week.

@Mishn0 2 года назад

My fingers were quivering over the keyboard primed for a comment on the carrier durability of the Seafire, but you got to it before the end. I read in a book somewhere about it, if they hadn't had the maintenance carriers like the HMS Unicorn, with spare aircraft aboard, the British carriers would have had to pull off station in Korea due to bent Seafires well before their scheduled rotation date. Excellent video, as always.

@agskytter8977 5 месяцев назад

A Norwegian pilot, who had served in the Royal Navy in the far east during WW2, compared the Corsair vs Seafire to the C3 Corvette vs Triumph TR6.. He loathed the Seafire and quit the RNoAF after the war when he had to fly the Spitfire Mk9.

@donbalduf572 2 года назад

Great job. I’ve seen restored Bearcats fly at air shows, but had no knowledge of the Seafire. I was very interested in conversion of a land-based fighter to carrier use, which is a challenge. Without a complete redesign of the structure it’s certain that limit loads would be reached or exceeded. They did well to make it work as well as it did.

@johnmurrell3175 2 года назад

They did it with the Mosquito as well, one major problem was the flight deck was too narrow so they needed to land off centre to avoid hitting the tower containing the bridge.

@rogerwhittle2078 2 года назад

Great analysis, Greg, I hadn't realised the massive difference between early Spitfire's and the mighty Mk47. On the subject of Max take off weight, I seem to remember reading that the Mk47 was the equivalent of the prototype Spitfire (K5054) taking off with 24 passengers and their luggage! The other point I am now aware of is; American Carrier prop aeroplanes were all much bigger and even heavier than the miniscule Seafire. Supermarine's managed to pack an enormous punch into what is actually a very small aeroplane. Well done again, thank you.

@rring44 2 года назад

I think climb should be added into the maneuverability discussion. In a vertical scissors, obviously climb is important. Also I think it matters in a sustained turn fight, if you know the enemy plane has an equal turn, but you have a better climb, you can turn and climb and that gives you a huge advantage.

Getting the charge air temperatures as low as possible was superbly important to prevent detonation.........an inter cooler between stages and after cooler before entering the engine were crucial to getting the best results. Great photos illustrating that RR engineering to accomplish that.

@dukecraig2402 2 года назад

I wonder how something like this would do turned into a hot vapor engine.

@wazza33racer 2 года назад

@@dukecraig2402 basically it was.......the fuel is sucked into both superchargers where it is vaporized and mixed evenly. Stanley Hooker explains in his book, that this system was on par in terms of performance with the German multi port,mechanical fuel injection on their engines.

@RWBHere Год назад

Thanks Greg. That's a decent assessment. One thing to bear in mind is that the British government and War Department are renowned for both understating and overstating figures in publicly available documents, so they have to be taken with more than a grain of salt. That obfuscation is deliberate; nobody wants to tell their enemy about the true capabilities of their defensive and offensive materiel. Nonetheless, the high attrition rate of carrier landings speaks volumes. Britain was making the most of what they had at the time, and the Spitfire and Hurricane were both early to mid-1930`s designs at heart. The RAF and RN had access to 150 octane fuel during the second half of the war, but it's supply was definitely limited at times because of the effects of U-boats on transatlantic tankers. The situation had improved markedly by the end of 1944, so aircraft could be flown with that higher grade fuel more frequently. The public had to survive with 70 octane 'Pool Petrol'. Oh, and a big thank-you to the USA for sorting out the bearings and lubrication in Merlin engines! The non-standard thread sizes in the Merlin 65 were a bit tedious for us at first, but tools are easy enough to produce.

@coreyandnathanielchartier3749 2 года назад

Another interesting video, Greg. Aside from several personal opinions and suppositions, a mostly factual study. When you are able to pick the competitors for a comparison, you can easily 'round off' the edges to achieve the results you desire. Your comments at the end actually summed up the entire affair: The Bearcat, F4U-5, and proposed versions of the Hellcat, were better at what they were designed for than was the Seafire, and indeed, Supermarine needed to design a new aircraft for the carrier fighter task. Creating lashed-up Spits or Hurricanes for sea duty during a war emergency is altogether different than continuing on after the war with this. I am aware that this company was engulfed in the Spitfire development and production throughout the entire war, and this would affect their future, for the worse. What they WERE able to do with this plane is impressive, considering the multitude of compromises required for the conversion to a shipboard fighter, however, the durability of this plane was predictable-the US rejected the Mustang for carrier use- it would require much redesign and view over the nose was poor, and it's only real advantage over the F6F was speed at extreme altitude, useful for escorting heavy bombers but of little use for ground attack or Naval strike force escort. I suppose it's a cultural thing, but the British have a tendency to carry on with a thing when that thing has outlived it's usefulness. We did the same thing in Korea........scrapping all the Hellcats and P-47's, and using the Mustang for ground attack.....a lot of pilots paid the price for that nostalgic whim....P.S. did I read correctly that there is a Wyvern study? One of my favorite planes....
