Bugatti 100P Rebuilt: The Plane That Could've Turned the Battle of Britain

concertina226 writes "A team of engineers is working together to recreate the Bugatti Veyron (or Bugatti 100P), an art deco-era fighter plane designed for World War II that would have broken the air speed record in 1940 — only the plane was never flown. Featuring forward pitched wings, a zero-drag cooling system and automated flight control assistance, plane was capable of reaching an air speed of 500mph, which would have made it the fastest and most advanced plane of its time."

      Counter intuitively, adding horsepower to a given aircraft design doesn't generally add much top speed. Instead you generally get improved climb capability.

      Horsepower is linear in nature: a horsepower (or a pound of thrust) grows exactly to scale of the amount available. But wind resistance isn't. Drag more/less grows exponentially. Particularly at the higher end of the flight envelope, doubling the speed of an aircraft far more than doubles the amount of drag on the aircraft. Thus, adding 20% more horsepower might only give you a top speed gain of a few percentage points.

      Above about 100 MPH or so, what generally makes a plane faster is "making it clean" - reducing elements of drag. For example, one of the worst possible shapes for creating drag is a circle. EG: a round pipe. Simply flaring the pipe can reduce the drag by 90% or more! Wires have the same problem - they create an intense amount of drag.

      An example of an early "clean" plane is the Mooney M20 series. Compare the Mooney M20E with the M20J. The E is smaller and lighter than the J, has the same horsepower as the J, but the J cruises at 200 MPH while the E does about 175.

      No. The whole reason you have forward swept wings is because they have good stall characteristics. On rearward swept wings, your stall originates near your root and propagates rearward and out, right over your outboard control surfaces. On forward swept wings, your control surfaces remain upstream of the stall, and thus you retain roll control deep into the stall.

      Forward swept wings are inherently unstable, but not for intuitive reasons. The center of twist on a rearward swept wing is ahead of the center of pressure. As the wing begins to flex, air pressure tries to push it back in place through negative feedback. It's the same idea as keeping the center of mass forward of your center of pressure. On a forward swept wing, the opposite is true, and air pressure tries to bend the wings further. This aeroelastic divergence leads to mechanical flutter and fatal structural issues that have only been resolved through the creative use of composite materials to produce anisotropic structures that place the center of twist forward of the center of pressure.

    Once you add armament and armor, the Bugatti would be a LOT slower. Probably slower than the Bf-109 that set the 469mph record.

    To compensate, you'd need a bigger engine. The 109, which was a small fighter to begin with (half the size of a P-51 and a third the size of a P-47), was already running a big engine for its size and barely had enough room to upgrade to the DB605 during the middle of the war. This Bugatti is tiny. It's powered by two 4.9L engines that produce 450hp each. In 1940, the 109 had the DB601 with a displacement of 34L and produced ~1200hp. By 1945, the DB605 was up to 37L and produced about 1800hp.

    The Bugatti wouldn't be big enough to run an engine that big, and while I'm sure one of you is going to ask "but it doesn't need to"... yes it does. If it's to carry enough fuel, armaments, and ammunition, it needs to have an engine that can propel it forward at combat speeds with all that extra weight, and an airframe that can hold all that. You don't get a lunar lander to the moon in Kerbal Space Program with a pair of solid fuel boosters, and you don't get an armed and armored fighter to loiter over Britain for an hour with two 4.9L engines. Not happening. Physics disagrees.

Planes have to be pulled out of the line and refurbished every so often. They can't fight forever. Unknown to the Germans, the British were far out producing them in fighter aircraft. Almost double the production. The problem the British faced was a lack of pilots to man those aircraft, and a degradation of the support infrastructure. Same as pilots, the ground crew, maintenance and airfield engineers were wearing out. But, so were the German ones. It turned into a battle of attrition. The Germans were deeper to begin with, but the British were losing less over time. The Germans eventually broke first. Their change in tactics was to cover the wearing out of their air force.

    And don't forget the limited range of the German fighters.

    The Battle of Britain was more the battle for southeast Britain. Unless RAF Fighter Command cooperated, by staying in a losing fight, there was basically no way for the Luftwaffe to seize and maintain air superiority in support of a seaborne invasion.

    The RAF had plenty of bases north or west of the Luftwaffe fighter's effective range; so if the attrition started going too badly against the RAF they had the option of temporarily pulling back to train up additional units, but could still surge forward if / when the invasion began. And Luftwaffe bombers would get shredded trying daylight unescorted raids against those more distant airbases.

    Ultimately, as painful as it might have been to people on the ground in that southwest portion of Britain, the Luftwaffe could only inflict a level of attrition that the RAF was willing to accept. It would be quite different if the Luftwaffe had the range to put fighters over any part of the UK, because then the RAF has to come up and fight, or its units get destroyed on the ground by fighter sweeps or escorted tactical bombing missions; though at least it would still have the option of training new pilots in Canada - so it wouldn't be quite as bad off as the Luftwaffe was by the end of the war where there was a good chance a trainee pilot would be shot down by Allied fighters before finishing flight training.

    It's worth looking to the history of the Bell P-39 as a good real-world example of such a design. The P-39 was also a mid-engine plane; it also tried to minimize the drag of the cockpit, had retractable landing gear and so on.

    It also turned out to be severely underpowered and could not meet its design goals without an absurd amount of post-production finishing (including 20 coats of meticulously sanded primer). It killed a quarter of the American pilots unlucky enough to fly one in the Pacific, and the British, who had originally ordered it, dumped them in less than 8 months. The Soviets, however, loved them.

    Bell improved the design with the P-63 Kingcobra, but ultimately I think the plane should be regarded as a failure, unable to compete with its enemy designs in air-to-air combat and plagued with development troubles that took years to correct.

    I would argue that the Germans would have had similar problems adapting the Bugatti's similar design, particularly noting that the Bugatti's twin internal engines COMBINED did not match the wheezy performance of the P-39's 1200 hp Allison.

    To reach the incredible performance advertised, the Germans would have had to focus on weight reduction, and thus eschew cockpit armor, heavy armament, and self-sealing fuel tanks, which suggests that it may have been subject to the same critical limitations that doomed the Mitsubishi A6M Zero. By 1941 both the British and the Germans had learned that armor, armament, and fire suppression were non-negotiable additions to fighter planes which could only be carried through dramatically increased engine performance--performance which could NOT be duplicated by a couple of hot V8s.

    Yes, in the right Universe this plane would have turned the Battle of Britain in favour of the French. Napoleon, Vercingetorix and Joan of Arc would have been standing in Blenheim Palace on top of Queen Elizabeth I, Queen Victoria and Disraeli's dismembered body parts, as they lay strewn amongst the wreckage of their Hurricane, Spitfire and Vauxhall Chevette ornithopter. The giant spice mammoths of the Russian tundra would have been no more after Trotsky's successful assassination of Joseph Stalin left Russia rich and defenceless, and the Japanese giant Iguana monster would be running rampant across Northern America smashing San Francisco to fine dust and weeing on the Washington monument turning the Potomac a bright radiated yellow colour. Cats sleeping with dogs, children refusing to obey their parents and every man wanting to write a book about it.
