Three Engines, One Unique Design | Blohm & Voss BV 138 [Aircraft Overview #85]

Ғылым және технология

Today we look at the Blohm & Voss BV 138. This three-engine flying boat was an often-forgotten workhorse of the Luftwaffe during WW2. Its unique hull shape earned itself the nickname of Der Fliegende Holzschuh or "The Flying Clog".

    F.A.Q Section Q: Do you take aircraft requests? A: I have a list of aircraft I plan to cover, but feel free to add to it with suggestions:) Q: Why do you use imperial measurements for some videos, and metric for others? A: I do this based on country of manufacture. Imperial measurements for Britain and the U.S, metric for the rest of the world, but I include text in my videos that convert it for both. Q: Will you include video footage in your videos, or just photos? A: Video footage is very expensive to licence, if I can find footage in the public domain I will try to use it, but a lot of it is hoarded by licencing studies (British Pathe, Periscope films etc). In the future I may be able to afford clips :) Q: Why do you sometimes feature images/screenshots from flight simulators? A: Sometimes there are not a lot of photos available for certain aircraft, so I substitute this with digital images that are as accurate as possible.

    Another amazing video sir. I knew this aircraft had an amazing service record but had no idea of it's troubled youth. As an interesting late and post war aircraft out of Canada, I would suggest the Avro 691 Lancastrian. It was a bizarre repurpose of a bomber design that actually got some post war buyers.

    Thanks to Rex for another good video! A bit of additional info: In 1944, two BV 138 were shot down by allied fighters and crashlanded in the sea just outside the island where I was born, near Ålesund, Norway. Some years ago, there was an attempt to salvage one of them. Unfortunately, when the BV 138 reached the surface, it broke into several pieces and went to the bottom again, where it still lies.

    Interesting fact about the Jumo diesels is that they are opposed piston 2 stroke diesels, with two pistons per cylinder and no valve gear at all. The pistons just uncovered ports, with the intake and exhaust timing being regulated by the slight difference in timing of each of the opposed pistons. When the engine was first designed, a number of engineers from Napier took part in a secondment at Jumo, and they later designed the famous Napier Deltic engines using design experience from this period!

    @@WALTERBROADDUS In the early 30s there was a lot of interest in Diesel Aviation engines due to their better fuel economy and less dangerous fuel, as well as the interoperability with Diesel boats and submarines (especially useful for long range seaplanes). The Jumo family of diesels were some of the most widely produced aviation diesels around, powering a number of long range/high altitude aircraft like the JU86P/R recon variants, BV138 and BV222, and the Fairey III (made under license by Napier & Son). Due to their huge weight and lower RPM they weren't really suited for fighters, so they don't get the same attention most of the time! There are a couple of Aviation Diesels in production today, most notably the RED Aircraft V12, which can run on off-road diesel or Jet-A in the 600-800hp engine class.

    The engine on the top of the wing will affect trim greatly, making handling a bit tricky, and waste a lot of power. So the original twinengined version is a better solution in every way, just stupid to not allow the use of more powerful engines! According to Eric Brown, R.N., who testflew it, it handled badly in any kind of seas.

It was completely unsuitable for SAR missions, so the Luftwaffe had to rely on the Do 24 (+Do18, +He 59 etc.) Perhaps because of the steep side walls, too? I can only guess, but perhaps the short hull of the Bv 138 created too much hydrodynamic drag (keyword: hull speed)?

    I love this very distinctive-looking aeroplane! - For me, the most interestingly overlooked feature of the affectionate 'Flying Clog' nickname is that it's a great pun - a piece of very service personnel-like wordplay by the Germans: "Der Fliegende Holzschuh" is the German for it - 'holzschuh' being quite literally 'Dutch shoe', so a clog, then - but that name in itself is a humourous adaptation (or playful mangling) of the title of one of Wagner's best-known operas; The Flying Dutchman'. Or, in German, 'Der Fliegende Hollander'. So, take the Fuhrer's favourite composer's possibly most popular work, twist it and get a cute, affectionate and funny nickname for the BV 138. - I can recall reading about the Arctic convoys, which this aircraft was frequently encountered snooping around at long range and seem to recall that the Allied nickname for it was "shad", short for 'shadower', but that may not have been universal. I'm amazed that such slow aircraft were capable of surviving the attentions of enemy fighters at all, but they did and that's a remarkable fact.

    The engines are very impressive. The high compression ratios required for auto ignition of diesel fuel (17:1 in this case) require a sturdy and usually heavy engine block, bearings, etc. Not ideal for aero engines. A comparison with the General Motors 71 Series engines, developed at about the same time, is inherently unfair since the GM is an industrial engine used in boats, busses, some tanks, generator sets, pumps and the like. But, nonetheless: GM 6-71 weighs about 2,150 pounds and produced about 170 horsepower without the supercharger developed later. The Jumo 205E weighed about 1,257 pounds dry and produced 560 horsepower, maximum continuous at sea level. For the time, that is very impressive.

    Just FYI, the 4 x DB 602 V16 diesels on the airship Hindenburg (LZ 129) produced 1,100 hp each and weighed 2,000 Kgs (4,410 lbs). Entered service in 1936, (P-W Ratio 0.24). Outstanding performance/numbers for a diesel engine of its day.

    @@andysweetland8645 Jet engines were not the only types where they were ahead of the curve, it seems. A bit of a surprise: you see pictures/videos of their U-Boat engines with exposed valve train on the top and this seems primitive compared with Fairbanks-Morse and EMD medium-speed marine/industrial engines, designed in the late 1930’s and still in use today. It did not occur to me that they would use diesels on the airships, but it makes sense. In addition to greater efficiency for range, you don’t have to carry gasoline. A threat to the big hydrogen “bomb” keeping you aloft.

    @@old_guard2431 (and the others above). Thanks all for the additional info, especially re the ACh-30 Sergey. A new one on me. Re diesels generally, yup the extra range/lower fuel consumption fuel consumption obviously does/did make sense. But due to higher compression ratios (than petrol engines - which means heavier sumps, heads, crankshaft/s, bearings, etc, etc), the problem is to get the the total output (hp) up while limiting all that extra weight. But going back to the 1920's/30's, as well as that point, generally it seems that "everyone" was scared of petrol engines "in the tropics". That's why the R-R petrol-engined British R100 airship was chosen to do the proving flight to Canada (Montreal), rather than the "competing" R101 airship which had diesels (Beardmores I think). That was even though both the R101 engines, AND the whole ships structure, was WAY overweight and had much less disposal lift (weight carrying capacity) than the R100. The result was the "inevitable" (?) crash in Beauvais (France), while on it's first proving flight (planned destination was Karachi, then part of India). So it crashed at about 10% of the whole way to it's destination. Incidentally, both the (in)famous R101 crash, AND the even more well-known German LZ 129 Hindenburg airship crash (Lakehurst NJ, USA) were NOT caused by having Hydrogen as the lifting gas. Hydrogen "simply" (and literally) "added fuel to fires" which resulted from the crashes being caused by entirely different root causes. But I should stop! This thread is about flying boats (which I also love)! Cheers

    The Küstenflieger were probably critical of the BV 138 because the Luftwaffe had a perfectly good Dornier flying boat in the Do 24 which, due to it being an export order for the Netherlands, never saw general use as a recon flying boat but was instead limited to air sea rescue operations

    The diesels were part of a long line of development of opposed piston diesel engines. Junkers aero engines was planning to produce a much larger, rhomboidal version, but they couldn’t get the prototype to work reliably. A British engineer solved the problem post War by changing it to a triangular configuration and reversing the rotation of one of the crankshafts. The result was the Napier Deltic.
