The pilot shown at 6:45, with his plane "Comrades in Arms", was my uncle, Eddie Musgrave, an RAF pilot with 137 Squadron. Flying his "whirlybomber"", he attacked the German auxiliary cruiser Togo (setting out on her maiden voyage after conversion, and about to be renamed Coronel), forcing the ship back to port in Boulogne and ending its cruiser career before it begun. He was later shot down over France, and is buried at Pihen-lès-Guînes.

[@PeteSampson-qu7qb]

Well done, Ed! Oh, those props! Everyone talks about the airframe and/or engines but a prop plane only functions as well as its prop. The Rotol constant speed props, for example, did as much to hold the line as the Spit, the Hurricane, or even the Merlin! It took several aeronautical engineering courses for me to understand that and I hope I can pass some of that along here. Anyone who knows much of anything about the P-47 Thunderbolt has heard of the "paddle blade propellors" that transformed it from adequate to excellent but almost no one explains why. I'll try to keep this simple. A propeller, like any airfoil, produces lift and drag and both increase with speed until, at some point, they cancel out. A thin airfoil, like a paddle blade prop or Rotol prop or F-104 wing, will continue to produce more lift than drag up to a high speed. An airfoil more like a Fokker D.VII hits that point at a much lower speed. Simple? Not really but we're getting.

The De Havilland Hornet was effectively a Whirlwind with Merlins. It was said to be the finest propellor aircraft ever by Winkle Brown. The Whirlwind was definitely ahead of its time and full of innovations which later other companies borrowed and used in their designs. DH Mosquito being one.

[@johnp8131]

My father was a De Haviland rigger/engineer for over 50 years from 1931 onwards. He would be turning in his grave because of your initial statement! The DH 98 and subsequent 103 were derived mainly from the 88's and 91's technologies which both pre-dated Westlands concepts. Although I would have agreed if you'd have said Westland Welkin, which were stationed just up the road from where I was. Although quite a few years earlier.

[@TheHarryMann]

I doubt the Mosquito was influenced at all by the Whirlwind. A really big problem with Westland was their lack of expansion of production capability... I think the dialogue says the de Havilland propellor was on the prototype which gave good performance... that’s the opposite way around to what was subsequently suggested! Peregrine production was terminated... Hives at RR just had to rationalise. But fantastic aircraft potential just the whole programme was 6 months behind requirements... NB. This was a high aspect ratio wing so potentially with development an excellent high altitude interceptor.. but not a dog fighter match for FW190 though

A fitter (now deceased) who was a member of our club, Scarborough Historical Aircraft Club, was based at Hucknall which was Rolls-Royce's test airfield.

[@richardvernon317]

Like all Petter designs what was under the skin was mostly a Dogs dinner. Lightning was another aircraft in that category. Canberra would have been as well, bar the fact that most of the kit the RAF wanted to put in it didn't fit or could be got to work in time, so the equipment fit of a Mosquito bomber ended up going into it.

[@pingpong5000]

Teddy Petter's obsession was to create small, lightweight, low-drag aircraft, if they wished to put Merlin's on it, they would have had to redesign the whole aircraft to carry the extra weight and power/torque, and that aircraft would have been the Welkin. The air ministry was looking for an aircraft to act as a flying test bed for the Frank Whittle jet engine and the Whirlwind was looked at for this but it was realized that even those jets would have been too heavy for the aircraft which is why it was left to Gloster to build one from scratch. The horsepower created by the early Merlin was less than a thousand so not much more than the Peregrine for a much heavier engine, also as all these engines were only around 40% efficient, the engines were actually producing near to 3000 HP but most of this was wasted due to heat, noise, friction drag, regarding the drag of the thick propellers and their extra drag and supersonic drag, keep in that mind.

[@Charlesputnam-bn9zy]

I remember seeing - that was in 1962 - in a 1944 (forgot the month) issue of the American FLYING Magazine an advertisement for scale models of warplanes of the time, including the Brewster Buffalo, Lockheed Hudson (with the tagline "Used with terrific results against Japs in the Solomons" !), the nazi Focke-Wulf FW-190, and the Westland Whirlwind. That's my 1st knowledge of this plane.

[@stephenjacks8196]

Same problem with Brit Air ministry as German RLM. Stuff (fuel, materials) was earmarked for existing designs before new designs. Mosquito was approved because it didn't use strategic Aluminum. Whirlwind used existing low demand engines. Problem with this and Me110 was that fighters require turning radius to turn with target when dogfighting. The weight of the engines extended out on the wings made banking, required for turns, slower than single engine aircraft without heavy wing weights. Only twins with competitive bank rate was Do335 and P-38 (not sure why ailerons were that effective).

[@alan-sk7ky]

11:10 of course not forgetting the DH Hornet/Sea Hornet. 380+ built so not a failure either ;-)

[@emjackson2289]

The Westland Whirlwind was - for my two pence - the perfect example of the very last of the first-half-of-the-war planes that simply couldn't be made any better than they were but were the ultimate expression of design and technology that had started with the Italian and Japanese (then German, British and Americans) c. 1934-35.

[@ofeliawotsits6080]

Nice to hear that Rotol blades were a success in the prototype. Becoming an apprentice at Dowty in 1978, blades were still a big part of their business, and they are still going. Always loved the look of the Whirlwind, it really did look the part with the cannons all mounted in the nose, it looked deadly. Two engines and the thin wing made it look like a race aircraft, and it should have been very fast. One of the early Airfix kits my Dad ever made when I was a kid.

[@bertmeinders6758]

Did your research include a magazine called "Look and Learn"? Besides filling in gaps in my education in the 1960s, it had a feature about the Whirlwind, which attributed its demise to the interaction between the propellors and the engines. I was only a schoolboy then; I didn't become an engineer until the late 1970s. But I did remember the outline of the article.

my uncle Hilton Ashton flew Whirlwinds, flying many 'Rhubarbs' and much night flying. great insight on the propellers !

[@gregculverwell]

When I was a child I loved building model aircraft kits. My favourite was the Whirlwind. As for fitting the the Merlin, I don't believe it was possible to do without a major redesign. The Merlin was a lot longer and 50% heavier. That would move the centre of gravity well forward. To be counter that would have required a much longer fuselage and / organisation moving to the wings forward. Then the wing area would have to be increased to compensate for the extra 1/2 ton of engines. By the time you do that it would virtually be a new aircraft.

[@alan-sk7ky]

Before you even got to the explanation of the real rason why a Merlin-powered Whirlwind was never made, I was already saying "It's because it would use twice as many Merlins as a Spitfire or Hurricane."

It is worth noting that in the Whirlwind the layout of the Peregine allowed for an excellent level of cowl streamlining. Not realy equalled with the Merlin until the 'streamline' 130 & 131 versions that had repositioned ancilliaries as used in the DH Hornet but by then the Merlin was a very highly developed engine.

[@markfryer9880]

I got to know the Whirlwind through a Commando cartoon magazine story in the 80s. Watching this video I just realised with it's development date that it must have been one of the first aircraft to feature the perspex tear-drop bubble canopy in 1940. That is far ahead of most other WWII fighters. I seem to remember that it also had hydraulic assisted control surfaces. I found this video interesting in that problems were not so much the engines but rather the propellers and constant speed hubs. The Whirlwind also fits into the same category as the Me 110 in the pre-war category of Heavy Fighter. The 110 was not without it's problems but found it's niche as a night fighter at great cost to Bomber Command.

[@nickbrough8335]

Looking at the success of the Mosquito and P-38, there is no doubt that the W Whirlwind would have been very welcome addition during the Battle of Britain. Thereafter the RAF didnt have much tactical need for such an aircraft and in the ground attack the Beaufighter and Mosquito were both more than adequate. In hindsight, if there had been fewer issues with the Peregrine engine, then there ought to have been more opportunity to test out other aspects of the design (cooling, flaps and propeller) before the WW entered service.

Propeller Mach drag problems were more extensive than usually accredited. The prototype Mosquitos propeller blades were trimmed a few inches because of vibration due Mach compressibility between the blade tips n the fwd fuselage. Ditto the Beaufighter.

Check out Matt Bearman's (cited by Ed) excellent series of articles in The Aviation Historian magazine. Although "modern" fighter designs were capable of reaching high transsonic speeds (in a dive) by the late 1930's, the shortcomings in the aviation industry's knowledge of supersonic aerodynamics had far-reaching and doleful effects on the performance of fighter designs, including the fabled P-38 Lightning.

Canadair developed in the fifties an aircraft called the dynavert. It had tilting wings to provide vertical lift. Look it up on KZbin. But what very few know is that the whirlwind was designed so that it could do the exact same thing. THAT is why it was developed with an engine that could run in both directions. Teddy Petters uncle Percy was the big driving influence in developing STOL/VTOL. The genius lay in adapting an airframe that could be converted to the same. Combining a tilting wing with fowler flaps thrust vectoring gave classified variants the ability to do high speed channel crossings and still land on very short to non existent landing site's in occupied France in particular. These variants though few in number were flown by the most highly skilled pilot's who built what they flew and knew the aircraft litteraly inside and out. The conventional wing spar was replaced by a tubular sleeved spar. All classified variants were fitted with self destruct to avoid the technical specifications falling in to enemy hands.

All these arguments regarding the Whirlwind are well rehearsed and rather circular in nature. Sorry - but this video is a Red Herring.

Even re-stressed, it was really too small vis wing-loading et al. 3) Let's also remember that all that additional heat from two Merlins would also have required much larger radiators - more drag etc etc...etc. As for the point about the DH airscrews.... Pah. The Spits used the DH airscrews too, - same blade-form, and had no issues with speed or altitude. Was DH's blade-form the most efficient out there...? No - but it didn't hold-back the Spitfires. Sounds like someone's been clutching at straws....!

So De Havilland scuppered the Whirlwind in order to make the Mosquito look good... The buggers!.. Having been born and raised in Yeovil I've always had a soft spot for Westland products. So many thanks, Ed, for shifting the responsibility for the failure of this gorgeous aircraft to a rival factory. (Joking)... A very interesting reassessment, as ever. 👍

I don;t recall that De Havilland was mentioned anywhere in the video. Where on earth did you come up with that?!?

[@billdyke9745]

@@GBooth the propeller that worked less well than the one on the prototype was made by De Havilland.

[@GBooth]

@@billdyke9745 That's a stretch. The Mosquito was designed to a totally different purpose and specification than the Whirlwind, and one that came some time later, as well. There's zero evidence of any attempt by DeHavilland to saddle the Whirlwind with poor props. Rather, it was a problem that was evident on many aircraft of the period in Britain, as well as the US and Germany. The difficulty - and it wasn't limited solely to DeHavilland's propeller division - was that the trans-sonic aerodynamics of propellers were poorly understood at that time. The shame is that no one in the RAF, at Westlands in the MAP or at the A&AEE or RAE ever thought to ask why the performance of the second prototype Whirlwind was superior at altitude to the production examples. Given the economic and resource considerations already in play in the Air MInistry and the MAP in the late '30's however this understanding - had it come - would likely have been too late to save the Whirlwind in any event.

[@johndell3642]

I think you're mixing up the Westland Whirlwind with the Westland Wyvern. I can't find any description of the crash you describe that matches any crash of a Whirlwind. However, it matches exactly the loss of the second Westland Wyvern prototype (VP113) on 31st October 1949. During a demonstration flight the engine failed and the pilot (Squadron Leader Michael A Graves) tried to make an emergency landing but overshot - Killing 5 year old Ann Wilkins and 40-year-old Edith Brown. 57-year-old Elsie Hockey died of her injuries shortly afterwards. Full details of the crash are on the Aviation safety website. aviation-safety.net/wikibase/74680

Wow, wow, wow. Hold on a minute. The Kestrel engine was used in the prototype Messerschmidt Bf109. I wasn’t aware of that, now that, would make an excellent topic for a video!

[@Steve-GM0HUU]

BF 109 production continued after WW2 in Czechoslovakia and Spain. I believe that a number of the Spanish built aircraft had Merlin engines. I also believe that today, if you see a Bf 109 flying, chances are it will have a Merlin.

[@drfill9210]

Yeah the rolls Royce connecting to the me 109 is well known

Yes, I was familiar with the Merlins added to the Spanish variants after WWII, just not the Kestrel added to the German prototype before the war. Still think it would make for an interesting video…

The prototype Ju 87 also had a Kestrel -the German engine manufacturers were lagging behind at that point.

[@pizzagogo6151]

That was great thanks, like everyone I always looked at it as great plane bad engines...The whirlwind still comes across as missed opportunity but exactly as you describe also people can forget the context of Britain’s wartime realities, not persisting with too many projects but sticking to making a lot of what was known to work ( especially for an aircraft that didn’t seem to have a role)- did make practical sense. (In a direct contrast to so a lot of Germanys lack of sense in project management). Sad , as it would be awesome if these had made in enough numbers for some to still be around & flying today.

[@fooman2108]

Didn't it seem that most of the early war fighters seem to have a prop change in pretty short order after they first flew? I know both the Hurricane and Spitfire were initially fielded with fixed pitch two blade props. This seems to a kind of a trend there....

[@sugarnads]

Those changes were due to evolving technology involving constant speed and variable pitch props.

[@fooman2108]

@@sugarnads So why didn't they do that with the whirlwind which seemingly (at least to my non-aerodynamicist eyes) had the same problem? It was of the same vintage.

[@duncanhamilton5841]

@@fooman2108 Probably because it would have been a waste of engineering time and resources. 114 built, and production stopped. Wartime average would be 1/3rd lost due to accidents. Of the remainder, 1/2 would be available at any one time. So getting performance gains on a 1st Gen out of production fighter, when heavier or faster stuff is coming down the line (Mossie, Beau, Cannon Hurri and Typhoon, Mk1 Mustang, Mk5/9 Spits), whilst you've also got Bomber Command placing huge demand on development of Wellington, Stirling, Halifax and Manchester/Lancaster - that would have been a total waste of time. Same thing applied to the Stirling - an excellent aircraft crippled by the wingspan. With a longer wing it could have flown higher and further, but why bother trying to make a 1st Gen heavy better, when you can concentrate that engineering time on making the 2nd gen planes better.

[@GBooth]

@@fooman2108 Because the leadership in the Air Ministry and - more crucially - the Ministry of Aircraft Production had already come to a negative assessment of the Whirlwind - more for economic than technical reasons - by the time the prototype flew, and curtailment of further development was a foregone conculsion. Moreover, as a new type in service, the Whirlwind's early months were spent working out the discrepancies and shortcomings of the original design which, as we know, were substantial.

[@fooman2108]

@@GBooth That is also a sad truth in the U.S. a manufacturer/designer can piss someone off and even great designs will just never be given a chance.... An example for about three generations was Grumman fighters (the cats, built by the Bethpage boilerworks (my dad has thousands of hours in Grumman aircraft), that nearly strangled any thought of a different company making fighters. McDonald-Douglas (now Boeing) are usually mentioned as not having made a FIGHTER for the USN for nearly 70 years before the Hornet/super Hornet.

[@Theogenerang]

If you want a really good analysis of an aircraft type you have to look past accepted folklore and speak to someone like the late Captain Eric Brown. Someone with experience in a wide variety of aircraft will always be able to pick an aircrafts strong and weak points. I suspect many of the folks who wrote about the Whirlwind in the 1950's had little to no experience in the type, let alone test pilot experience. Glad to see this interesting aircraft given a second look.

Bit of a medium are you? 😂

[@dubsy1026]

Re the DH prop, I'd heard some issues with Spitfire Vs having constant speed unit failure (prop type not specified, but I expect DH) at high altitude, and later on the Spitfire abandoned DH props all together. So seems like DH props were generally a bit shoddy?

Great video. Indeed puts all I thought I knew onthis may I state brilliant combat aircraft. Mach problems with props at the start of the war is a problem new to me. Yet seeing your great video Ed the reason this plane failed is the concept requirement of an interceptor in stead of longrange escort as primanal war.

[@romanbrough]

I recall reading an account by a Whirlwind pilot. He liked it, but he suggested that it needed three changes. 1. Switch to Merlin engines. 2. More ammunition. 3. The ability to move fuel between engines. Their squadron gave up the Whirlwinds and were given Hurricanes. They were not at all impressed.

[@GBooth]

A great presentation, Ed. Thank you for bringing us up-to-date on the research about this 'kite. I'd also recommend you check out Greg Baughen's series of books on the RFC and RAF over the 1910-1945 period (not yet a completed series. Currently at approx 1942). While not specific to the Westland Whirlwind, his study of the RAF's interwar planning and procurement sheds additional light on why the Whirlwind's production was curtailed. As you point out, it had as much to do with economic and production considerations as with shortcomings in its design and performance. While one of my favorite aircraft of the period and certainly an aesthetically attractive machine, it sets the lie to the old adage "if it looks right..."

[@demos113]

[@mikepette4422]

I always assumed that the Peregrine ,no matter its capabilities, were all that was keeping the Whirlwind flying at all. Given the desperate need for Merlins it just seemed that from everything I read on this subject that the Peregrin was available for this plane and had the Merlin been the primary engine it would have been totally cancelled before the Battle of Britain. Glad you confirmed my rather general theories and an excellent video indeed.

[@michaeldillon3022]

[@barryervin8536]

Re-powering the Whirlwind with Merlin engines would have required it to be made into almost a different airplane. It's surprisingly small and light for a twin engine fighter. The original concept was a fighter with high power from 2 relatively small engines. A Merlin powered Whirlwind would have had to be the size of the Mosquito.

[@stevejohnson4774]

Westland themselves proposed a Merlin powered Whirlwind and is evidenced by the letter mentioned in the video which survives in the national archive although a copy can be found on the secretprojects site. It maybe a widely held belief a Whirlwind could not accept Merlins but is one that holds no water - you are essentially arguing against the designers and manufacturers

[@jerryavalos9610]

Perhaps not, look at the DeHavilland Hornet. Small twin engine fighter with two 2000 hp Merlins.

[@SvenTviking]

If they had developed the Peregrines, in the same way as the Merlin, they could have seen 12-1,350 hp and well over 400 mph. But it was a single aircraft engine, and as such, not worth keeping the production line open,

[@pylon500]

One almost wonders if they would have just got ONE of the latest Merlin, and stuck it on the nose and put the canons out in the wings...

[@nicholasconder4703]

@@stevejohnson4774 Barry has a point. The issue lies in weights and balances. Adding two Merlins to the airframe would have increased the weight in front of the centre of lift, a change in the centre of mass requiring a redesign of the wings, changing the fuselage, or some other change to facilitate using the larger and heavier engines. It would be like the Boeing 737 Max-8 problem all over again, without computer assistance to compensate for the change in aerodynamic performance of the aircraft.

Thanks for revisiting your original analysis of the Whirlwind, I haven’t seen your original episode but I am sure that your original video was based upon the available information available at the time, no matter what aircraft gets reviewed there will be conflicting opinions within the aircraft enthusiasts world, but in this case it seems that a consensus has been reached, at least for the whirlwind. In my humble opinion the Whirlwind was just the right aircraft but at the wrong time and place in history, and perhaps we should be thankful for that, maybe if it had been a good aircraft the RAF and other airforces would not have had the excellent aircraft we did, The Hurricane, Spitfire and Mosquito, and the big daddy of heavy bombers that was the Lancaster, all with the roar of the mighty Merlin, the most famous engine in the most famous aircraft of WWII.

[@dphalanx7465]

While the Peregrine is the key problem, there are a lot of other things you could fix that would enhance and extend the service of the Whirlwind. 1] Belt feed for the cannon; doubling ammo load. 2] Cross-piping of fuel tanks; increasing range & mitigating battle damage. 3] Replacement of air intake filters with larger, more efficient types; improving engine performance. 4] Extension and further streamlining of nose; easier access to armament & increase in speed. 5] Removal of leading-edge slats; reduce landing problems & save weight. It would have surpassed the Hurricane and kept up with the Typhoon to the start of 1944 probably, seeing another year in service. In fact, a Whirlwind Mk.II with improved Peregrines; 100 octane fuel, and the improvements listed above might have delayed/reduced the numbers of Typhoons produced, if not stymied the type altogether.
