Defeated By...A Lack Of Glue?: Focke-Wulf Ta 154 Moskito

In this video, we take a look at the Focke-Wulf Ta 154 "Moskito, a mid-World War II fighter and/or night fighter from Germany. We first talk about Germany's increasing need for a dedicated night fighter as WW2 progressed, as their advances slowed and Britain and America increasingly would attack German cities. We look at the request put out by the German Air Ministry and the Ta 154's competition in the Heinkel He 219 and the Junkers Ju 388. We then talk about the comparative superior performance of the Ta 154 over the other two designs.
Then, we talk about how the Ta 154 generally copied a British aircraft known as the de Havilland Mosquito, being an all wood design that would be held together with a strong adhesive rather than nails, screws, or rivets. We look at the troubled prototypes of the Ta 154, frequently crashing and seeing ever decreasing performance . We talk about the "straw that broke the Moskito's back" in the destruction of the factory making the glue for the plane, and how their replacement adhesive utterly failed, thus dooming the Ta 154.

1 To be fair the Germans had an excellent process. TEGO film was not a glue but an adhesive sheet that was placed between wood ply and then pressed by male and female dyes into a 3D shape. Heat was applied to cure the glue and mold the plywood into shape. It was effective and strong. 2 The Ta 154 was not really cancelled because of the replacement glue was acidic. There were many reasons. a/ The Ta 154 was promoted by the powerful Erhard Milch who saw it as providing the benefit of not needing Aluminum and being able to use a cheap and available Jumo 211 by 1944 he had fallen out of favor due to an argument with Hitler and he was no longer in a position to promote this anachronistic project. (which he did obsessivily to the point of suppressing the He 219) b/ However analysis showed that with the improved 1500hp Jumo 211N the aircraft could not cope with the Mosquito and that the Jumo 213 would be needed. Junkers abandoned Jumo 211N development was abandoned to focus on the Jumo 213 which was not realistically available till mid 1944 leaving only the 1450hp Jumo 211J engine. -It's not surprise that the Mosquito with a 2 stage inter-cooled Merlin using 100/130 octane fuel would outperform 1 stage inter-cooled Jumo 211 using 87 octane. c/ The cockpit tended to disintegrate on impact which needed redesign. d/ By 1944 it was obvious that the Jets like the Me 262 and Ar 234 were going to work. The Ta 154 was now a total waste. It wasn't only the air ministry that wanted to kill of the Ta 154 it was the chief designer at Focke Wulf, one Kurt Tank. He wanted to concentrate on the Ta 400 Jet fighter and the Fw 190 and Ta 152 which had wooden wings with a steel spar. 3 The foolishness of the Ta 154 was that it was started in late to mid 1942 which is too late to complete development in time to be useful. Germany's failure was not developing the Fw 187 which would have given the Luftwaffe a Mosquito/P-38 equivalent in 1940 by firstly denying it the DB601 engines it needed and secondly the air ministry ruining it by trying to turn it into a zerstoerer. Imagine someone in the USAAF insisting the P-38 needed a rear gunner before it was allowed to enter service.

The DH Mosquito was in its element in the temperate European climate. When it was sent to the humid, tropical climate of the CBI theater, it wound up having the same problem with the glue not holding up as the Ta 154 and was soon withdrawn. FYI: German aircraft designations were the the first two letters of the manufacturer, or in the case of double named makers, the first letters of each name, e.g. Focke-Wulf - FW; Blohm und Voss - BV. Kurt Tank (Koort Tahnk, please), an aeronautical engineer and test pilot who led the design department at Focke-Wulf, was so well respected (the FW 200 and FW 190 were his designs) that he was the only designer to have two of his designs be given the 'Ta' designation rather then FW: the the high-speed/high-altitude Ta 152, an iteration of the FW 190; and the ill-fated Ta 154.

Many thanks for this video! I've had a soft spot for this plane ever since I thought that one of my late grandfather's may have flown it! It freakishly turned out to be another German pilot with the same name and age (I found photos - def. a different person, that one being with the day fighters and then test pilots, my granddad being with the night fighters). At any rate, I managed to get my hands on "Focke-Wulf Nachtjäger Ta 154 "Moskito": Entwicklung, Produktion und Truppenerprobung" by Dietmar Herrmann. As a German engineer, he arguably wrote that book as the ultimate authority: he used the original plans, designs and was able, at the time of writing, to still speak with some of the designers, engineers and pilots. As the book is currently packed away due to construction, I can't immediately check, but I do dimly remember that, while the glue was a problem to a certain extent, it was not the top issue. That *did* still fall to the lack of suitable engines and, as so often, the N**i bureaucracy and infighting. Even when the engines were available, they weren't allocated with any priority to this program. They couldn't get this high enough up the flagpole (which generally meant somehow getting this inside the short attention span of the dude with the idiotic mustache).

[@thiscouldntblowmore]

In Finland we too tried to make mostly wood construction fighter plane and it too failed, among other things but mostly because low quality wood glue, maybe domestic, maybe sourced from Germany. As far as i remember, especially parts of the tail tented to rip off in a dive with catastrophic results, the planes were called VL Myrsky.

[@bigblue6917]

Interesting that Germany did not have enough carpenters for this project. One of the big successes of the Mosquito was that parts were made by small furniture makers and sent to De Havilland for assembly. But knowing that when Germany cancelled a number of defence contracts in 1943 the scientist and engineers from them ended up fighting on the Eastern Front I think that is where the furniture makers ended up. A couple of years ago I had a brief discussion on another KZbin channel about the poor quality of the glue Germany used during the war and he pointed out that the Germans were using slave labour to make the glue. And they were deliberately sabotaging the glue so that it would not work.

[@obsidianjane4413]

Yep pretty much. The Nasties would draft the specialty carpenters needed for cold molding as "not essential workers". Opps. Both the plane factory and the glue (chemicals in general) relied on slave labor in the late war, and yeah, quality wasn't a high priority for them.

[@williamzk9083]

The Mosquito was highly limited in production due to limits in specialist wood supply and specialist workers. Only 7000 were produced (about 2000/year) and it would be impossible to produce more unless the air frame was switched to metal. It was fairly pointless for the Germans to try to emulate as they had even worse shortages, certainly no ecudorian balsa.

[@enscroggs]

Apart from the defective substitute glue, what about the wood itself? De Haviland built the DH.98 Mosquito from wood because that was their preferred material, the argument that the project would not stress the supply of aircraft-grade aluminum was just icing on the cake. The pre-war de Haviland Albatross airliner had already proved the concept of high-performance all-wood construction aircraft. In designing the Albatross and later the Mosquito, de Haviland learned that the choice of wood was paramount to success. Their ideal material was birch plywood with balsa wood (ochroma) cores. Excellent birch was available from U.S. and Canadian sources, and balsa was available from Ecuador and other regions of South America. Later on, due to shortages they substituted American Sitka spruce for the balsa wood. Birch was also the prime material used in the Hughes Hercules flying boat, though it was unfairly and stupidly labeled the "Spruce Goose" by reporters. Without any background in designing all-wood construction aircraft, what sort of wood did Kurt Tank select for the Ta 154? There was abundant birch in Russia, but by 1943 Germany was on the retreat in Russia -- not a good situation for harvesting and transporting lumber. There was good spruce in Norway and Sweden, but that required transport by sea in ships, again not ideal for a new aircraft at that time in Nazi history.

[@scientificconsideration8294]

Well there is also a fair amount of birch in central europe, though it was simple plywood that was ultimately used for the Ta 154.

[@enscroggs]

@@scientificconsideration8294 IN the construction of the de Haviland Mosquito, there was a final step. Before the engines and control surfaces were installed the whole aircraft was covered in a layer of doped linen fabric. Did Tank use something similar?

[@williamzk9083]

-The Americans had developed the Duramold process, Dehaviland merely copied it using slightly different woods instead of birch. It was used on the Hughes Hercules H4. so called spruce goose which had no spruce but lots of birch. -Only 7000 mosquitos were produced. It was impossible to increase production due to limits in supply of specialists woods and worker. For this reason the Germans shouldn't have bothered and concentrated on hybrid air-frames with steel spars and wood wings as in the Ta 154 which were quite successful.,

Great video.

The Mosquito was very hard to intercept, and was one of the first allied bombers to hit Berlin during the day, which really pissed off Hitler and Goering. But what pissed them off even more, was why the German aircraft companies, supposedly the best in the world, couldn't design a similar or better plane.

Republic and the RAF worked on fitting the Merlin into the P-51 at the same time since it provided better high altitude performance plus Packard would be producing those soon. The P-51 using the Allison was as fast as a Merlin Mustang at low altitude so it was fitted with dive brakes to become the A-36 Apache fighter bomber. The US also considered using wood construction for aircraft, primarily flying boats for transporting troop with gear to the Pacific Theater. Howard Hughes won the design competition to eventually build the Spruce Goose. The adhesive company had some difficulty coming up with a suitable glue and finally did after experiments showed how to use it. It had to be applied in a thin coat to one surface then clamped to another piece before being heated to set then cure the adhesive. For wing and body panels, ladies applied a very thin coat to a very thin section of birch veneer then used clothes irons to press it down on another section of veneer to set and cure the adhesive. That adhesive and method of application resulted in producing very strong laminated wood that wasn't affected by temperatures and humidity to this day.

This is the first time i've heard of this Luftwaffe WW2 warplane. The FW TA 154 had some differences to the de Havilland Mosquito. It had a tricycle landing gear (similar to the Lockheed P38 Lightning), and a high wing, whereas the Mosquito had a mid-wing (like many small and mid sized planes). Also the TA 154 had (good) air cooled engines like the highly sucessful single engine FW 190, whereas the Mosquito had the glycol cooled Merlin engines. The British had a lot of pre-war furniture makers, who were experienced in wood gluing and plywood manufacturing, meaning that they could apply these skills to making the Mosquito wings and fusilage. Something that Geoffrey de Havilland was very aware of. It appears that the Germans did not quite have those levels of woodworking skills. De Havilland also deployed a superior monocoque construction method for their airframes in two upper and lower halves shells, that were later screwed and glued together. FYI, over 3000 Mosquito's were manufactured in the UK alone.

[@PORRRIDGE_GUN]

The Ta154 had Junkers Jumo J211 or 213 engines. These are not air cooled. They have annular radiators but are inline, liquid cooled engines. You are confusing the FW190A series, which had air cooled BMW 801 Radials

There is an argument that Britain could have substituted many of the Lancaster heavy bombers with Mosquitos as the ratio of crew to bomb load was identical.

The Mosquitos would have been harder to shoot down and the British would have lost far less planes and aircrew. There would have also been more aluminium available for other aircraft.

IMHO even a genius like Kurt Tank sometimes may design a pile of scrap. The crew had almost no side view because the engine nacelles were mounted at the same height as the cockpit. Thus, formation flights were quite impossible. 14:07 Please note that the Ta 154C had an elevated cockpit to adress this issue.

[@obsidianjane4413]

It was designed as a pure night fighter. Visibility wasn't a priority since there wasn't supposed to be anything to look at.

[@OliverSchroeder]

​@@obsidianjane4413Poor visibility in a night fighter sounds not like a good idea. The Me 110 G night fighters flew with an extra crew member (who served as an aircraft mechanic on the ground) to have another "pair of eyes" on board.

[@obsidianjane4413]

@@OliverSchroederThat is not true. The 3rd (usually 2nd because gunners were often not carried esp. if it were a schragemusik version) member was the radar operator.

[@OliverSchroeder]

​​@@obsidianjane4413Anyway, it's complete nonsense to say that visibility would be of secondary importance for a night fighter - it is crucial! At least when using the Lichtenstein radars, the final approach to the target has to be flown on sight. I cannot imagine that the A.I. units of the Mosquito N.F. were so sophisticated that you shoot right into the blackness where the green dot of the radar screen indicates a target. I suppose the cockpit arrangement was adopted from the Fw 187 Falke, but since this was a low-wing plane, it did not affect the pilot's sight there. Apart from material defects like glue or landing gears, the cockpit enclosed by nacelles was a serious design flaw. The Ta 154C blueprint clearly indicates that a rectification was mandatory.

The Ta 154, should have been developed earlier and gotten into service by at least the fall of 1943. It could have been a frightening scourge against Allied bombers because it was reasonably fast and could carry four MK 108 cannons, which would have been a frightening danger to Allied bombers.

The Fw 187 Falke was the only realistic opportunity the Germans had but they messed it up by insisting it be turned into a zerstoerer.

[@jameswebb4593]

One should always be careful with the majority of these pods , as more often then not , they are inaccurate or suffer major omissions . In this case the D.H. Mosquito also had serious Glue failures , not in northern Europe but in S,E.Asia . Wings were detaching resulting in the grounding of Mossies . The problem was caused by the high humidity effecting the glue. Ciba Geigy developed a new glue at Duxford , which I believe became Locktite.

[@OliverSchroeder]

Now keep in mind that they cancelled the Fw 187 years earlier, and then they wanted something almost exactly like it. Possibly one of the biggest missed opportunities.

The Allison and Merlin engines were very, very comparable. The defining difference was the Allison's poor supercharger (I remember reading somewhere that the planned 2 stage supercharger for the Allison got "organized away" by the US military, dooming it to low level duties... Apart from the P-38, which had decent superchargers).

[@nerd1000ify]

The USAAF went through a period of 'turbo-mania' where they more or less insisted that they would not buy anything that wasn't turbocharged. As the USN was simultaneously insisting they they would never buy any liquid cooled aircraft ("it makes as much sense as an air cooled submarine!") Allison designed the V-1710 with the expectation that it would always be used with a turbo, and thus provided a supercharger that was practically optimised for sea level (the turbo would boost the air up to sea level pressure before feeding it to the engine). Not long after, it became clear that the weight and bulk of a turbo installation was too much to fit in a single engined fighter with a V-1710 without a significant performance penalty. So the P-40, P-39 and P-51 got hamstrung.

[@cabanford]

@@nerd1000ify I'd read that Alison was told an amazing 2 stage supercharger was being built for the V-1710 by another Army appointed company (forgot which) that then dropped the ball and never delivered. Can anyone corroborate this?

[@nerd1000ify]

@@cabanford I don't know about an external contractor, but Allison did eventually develop their own add-on supercharger that could be bolted to the back of the engine. It even had a hydraulic coupling like the supercharger on the DB60x series engines, so the speed was continuously variable. It was used on the P-63 and boosted its performance a great deal, but I don't know of any other applications.

[@paulholmes672]

The P-38 had only V-1710F's with a single stage supercharger. You had only one gear ratio at a time, and had to pick at manufacture. Lockheed added GE TurboChargers in the booms, which gave the Lightning all altitude performance, like the P-47.
