My father had an aircraft identification book printed in the UK at the start of the war. It contains the He-100.

In war thunder, this thing leaks coolant after being hit by a pebble, so at least they got that right.

The 100 is a beautiful airplane, but looks only get you so far, you did very well in explaining it's weaknesses against other aircraft at the time in particular other German aircraft.

excellent!

I felt like I was watching a history documentary, keep up the good work!

Who needs millions of dollars to do a documentary.

Excellent video. The evaporative cooling had been tried before - the Supermarine 224 / Goshawk of around 1934 used it and some lessons were learned by Mitchell which fed into the spitfire design. Evaporative cooling seems to have been something that excited designers but was in itself a dead end in a warplane.

Absolutely fantastic audio/visual lesson Bis! It was on par easily with most history documentaries.

This was very well done, I learned a lot about an obscure aircraft. This also help give insight into not just the research and development of a single aircraft, but advancement in aviation of an nation as a whole. I really hope you make other videos about obscure aircraft of all nations that give the same insight like this one has.

I decided to give you oak leaves with the Iron Cross

That is a really informative, impartial factual piece of cool history. And excellent delivery with the VO (voice over)

I've never heard of this airplane. Thanks for the information. Very well presented.

But would it cool a GTX 1080 oc ?

Fascinating, I knew nothing of the 100.. I'm a big 109 fan, which is how I discovered this video. I found it compelling from start to finish... Keep it up!!

Thank you for making these videos. I didn't know I was missing this information in my life. It's great to learn more!

Excellent video - done with integrity and apparently well researched, best results of any endeavor always acquired by the love one has for the work that goes into it, soberly objective ... Thanks again Bismark!

Not only a informative but well made. The History Channel could learn a lot from you...like...for instance....how not not make their videos dumbed-down and boring long winded andddddd ... saying stuff in 8:30 instead of 45 minutes. great job THANKS!

Finally, an explanation of the German evaporative cooling system that I can understand!

I do like the passion you express thought your way of telling the storie...I really like it.

I kept seeing Your videos popping up on my feed, usually dismissed them since I had something else to watch and usually they were gaming videos, of which I had plenty to watch.. I never imagined I missed out on so many excellent quality (informative, coherent, visually enticing) documentary styled videos.. wunderbar my dear friend

Excellent video - again. From the sources I've read, it was superior in all aspects to the ME109. The HE100 v8 version removed the experimental radiator for more conventional one and still showed excellent characteristics. Its range was also superior to the ME109 and used fewer parts. It's a pity/lucky it wasn't produced at the time of the original completion to realise its true potential.

Excellent, well balanced and researched presentation!

Superbly composed video with clear, informed, well structured narration. Top notch.

Concise and thorough explanations. Altogether excellent work! Keep up the great jobs of all your videos. Thanks.

Well done and educational. I've been a long time subscriber and you never disappoint. Thanks for this Bismark!

Great video! I had never heard of the He-100 before.

A very obscure topic and an interesting analysis. I always enjoy and appreciate your productions for your insugbts anspd clear explanations. Thanks!

The visuals are a bit suspect, but the commentary is top notch and informative. Thanks!

Very good insight. I had no idea about the clever but highly vulnerable cooling system in the He100 design.

this is an amazing video, thx for the clear explanation!

I love videos like this! I actually read about this plane just the other day when I was reading about the test pilot Fritz Wendel.

I am never disappointed with your videos, another excellent presentation. Thank you.

Very informative video! More like this would be cool! Love all your other videos too! : )

Maybe an idea for a future video can be the advantages and disadvantages of radial engines and inline engines? I feel like a lot of people would appreciate some clarification in that area. Also that radiator idea is absolutely genius even if it isn't practical. Classic German engineering! :)

Great documentary, amazing English speech. I had never heard of this plane before so this was very interesting. Yes, Willy did seem to get more orders than his fair share!

Love your videos. They are so informative, intelligent and entertaining. Please keep up the great work. Greetings from Austin, Texas.

According to Nowarra the reason for the He 100's cancellation was quite simple: Having a prototype fighter be the fastest in the world stole the 109's spotlight, which cast a bad light on Udet's Luftwaffe. That's also why Heinkel's team wasn't allowed any other record flights after the 209 (which was called 109R to make it look like it was a deviation of the serial production 109). It should also be said that Udet presented the craft to the French as "the newest German fighter" and then asked Heinkel "How are you doing with the serial production?" This annoyed Heinkel greatly as no order had been given to get the factories up and running, and there never would be one, of course. Additionally, the surface cooling was more resistant to damage than the normal cooling cycle since a hole wouldn't leak as much water as one in a standard water-cooled powerplant. NEvertheless, an amazing video.

3:30 "Before we turn our attention to the actual plane design.... let me introduce our new sponsor, Raid: Shadow legends." :D

great video. I was about to like it when I found that I already had. ahhhhh, now I know why the story was familiar. And yet, enjoyable all over again.

Very well done. Excellent work!

thanks again for these interesting documentaries-I believe RJ Mitchell; designer of the Spitfire, used the wing/floatplane structure of the Schneider Trophy S5/S6 aircraft for heat sink/heat dissipating of engine coolant thus removing the high drag associated with external radiators. I am sure the practical aspects of such systems in the field plus combat vulnerability would rule this approach out.

He 100 was and still is one of my favourite German Aircraft I have in War Thunder

Wow, I learned a lot and you did a great job with a documentary.

Another excellent and informative video. Many Thanks Bro.

Great video Bismarck, you now have your latest subscriber. One thing i'd like to point out is that the Supermarine S6B had the same type of cooling system as the He-100. Mitchel designed the S6B as the fastest racing aeroplane of it's day with liquid cooling within the skin of the airframe for the ultimate in streamlining... However when he designed a fighter aeroplane, in the form of the Spitfire, he deliberately chose to use a coolant radiator with the 'Meredith Effect' instead! That may well have been for practicality and also serviceability, at the small cost of just a few knots. The Spitfire was designed with a radiator and not such a cooling system for a reason, and not because the manufacturer did't think of it or couldn't produce it. So the He-100 as fantastic as it most certainly was, perhaps wasn't robust enough for service life along with diplomatic and other technical issues.

I watched this good and informed discussion of inline engine liquid cooling. You have to admire the quality of draggy giant-displacement air-cooled radials doubling as bullet-shields for their pilots. They also have much shorter crankshafts that get along better with all the inertia of a giant propeller. Stories abound of Allied aircraft returning home with entire cylinders shot off their radial engines. My uncle was a P-47 pilot so I grew up knowing about it.

Fantastic clear narration and great content!

That was an excellent video Bismark....keep it up mate....

That cooling system is very interesting! You never see much about this plane, an intriguing little gem.

The he 100 is probably one of my favorite low tier planes in war thunder

Thanks for a great video about a plane I had been interested in. I always wondered why it never made it into production as a fighter. You explained it very well.

very good video. Believe it or not, this is the kind of topic i love learning about in detail.

by your brief description, the cooling system of the he-100 seems much like the cooling system of a refrigerator.

"Come, Heinkel, show us the meaning of haste"

Liked! Always good to learn something about aircraft and aeronautical history ;)

As always, Outstanding job! Thank you

The He-100 with surface evaporation cooling system was an amazingly fast aircraft, but not suited for a fighter aircraft because of its extreme vulnerability to any kind of battle damage. However, that version of the He-100 would have made an excellent high speed photo reconnaissance aircraft, like the British PR Spitfires. In that role, its job would be to avoid combat, especially since it would be completely unarmed, carrying extra fuel in the wings instead of guns and ammunition. The Luftwaffe really needed a high speed photo reconnaissance aircraft during the Battle of Britain, for low level work especially. The old photo recon Dornier Do 17’s were just too slow and vulnerable. And the ultra high altitude Junkers Ju 86R was very difficult to intercept, but the extreme altitude (36,000+ feet) made for low detail photos, even with huge cameras - you could tell the difference between a single engined and a twin engined aircraft from that altitude, but you couldn’t tell the difference between a Hawker Hurricane fighter and a Fairey Battle target tug. Often the Luftwaffe ended up bombing British airfields that didn’t have fighter aircraft!

I will bet they never lost one of these due to wing Icing.

Very well done video!!

Ein wahrhaftes meisterwerk von video !!! A truely masterpiece of a video !!! Mach weiter so Bismarck

Fantastic production

That cooling seems like heat pipes of some sort.

Good stuff Bis, keep them coming.....

Very well done! You have your work cut out for you good sir. Expertly conducted research, easy to understand due to a well written text, and great archive video material! Have you considered documentary journalism as a career?

Lol wish I would have watched this sooner, I got the He-100 the day it came out and spaded it in about 2 ours and never cared to look at a x-ray of the plane, I was amazed at how fast it was and it was almost impossible to over heat, I didn't even notice that the cooling system was so vulnerable until I finally got shot at by a spit and noticed all the leaks, the plane was just so damn fast the enemy never had a chance to shoot me ... now I'm done with the he-100 XD

the cooling system would be problematic in a dogfight or sustained steep climb since that would mean high engine throttle and low airflow. the plane would burn up.

You are amazing lad. Better than most official documentories to be honest lol.

Awesome vid. Keep up the good work.

Its funny to hear you talk about some of the reasons the He-100 was likely not adopted by the Germans. Especially the coolant being so spread out. When I viewed the X-ray view in War Thunder I was like "Shit.... one shot by an enemy plane or stray bullet from even rifle caliber ground AA guns and I'll have to RTB immediately!" Great innovation to give maximum performance but a huge Achille's Heel. Ty for video. Well edited and put together.

can you imagine how hard that cooling system would have been to maintain in Russia?

Appreciated your video very much - thank you!

Very interesting. Hope you continue the good work! Thanks a lot!

Hey Bis, you missed something in your overview... the final model of the He 100, the D-1, abandoned the evaporative surface cooling system and instead used a larger version of the retractable underbelly radiator. It was inserted in a "plug" below the cockpit, leading to a wing with slightly more span. It wasn't as retardedly fast as the original of course, but still capable of around 644 kph in level flight... a number only approached, but not reached, by the Bf 109 with the F version in 1941! It also had a third more range than the Bf 109, which would have made it much better suited for escorting bombers during the Battle of Britain. This could have offset the need for the Bf 110 as an escort fighter, which also used the DB 601... and thus, the problem of engine supply for the He 100 basicly solves itself... especially considering that the Bf 110 needed 2 of the engines. Speakling strictly about engine supply, for each Bf 110 C built, 2 He 100 D-1s could have been built! The D-1 is also the version that is now implemented in War Thunder... at least it is named a D-1... but its actually a D-0, still using the fragile evaporative surface cooling system and with the engine MG FF replaced by a third machinegun. Want to guess the battle rating? It's 1.7. Yes. You read that right. A plane that can keep up with the ingame Griffon Spitfire XIVe at 5-6km altitude is fighting pre- and early war monoplanes and biplanes... The He 100 is now officially the most criminally undertiered plane in War Thunder. One last thing about the cooling system... it turned out that the cooling capacity wasn't sufficient for more powerfull engines like the later DB 605, and there was no way to increase the performance of the coolant system at all... it was recognised as an evolutionary dead end. The Bf 109 is already labeled as a fighter that didn't have as much development potential than the Spitfire or later fighters, with this cooling system the He 100 would have had basicly NO development potential at all! Which is, IMHO, one of the main reasons for why it was abandoned on the final D-1 variant. Whenever Ernst Udet is mentioned, I can't help but get angry about him... what an arrogant, ignorant and spineless bonehead! He might have been a good fighter and stunt pilot, but he totally failed in any other capacity, be it as test pilot, as the man responsible for the excessive dive bomber focus of the Luftwaffe which lead to such grand things as the He 177 requirement for dive bombing capability, and lastly... at life itselt, by becoming an alcohol, tobacco and methamphetamine(Pervitin tablets in germany at the time) addict and finally comitting suicide after the failure of the Luftwaffe in the Battle of Britain. Maybe I am a bit harsh on him, he didn't choose the responsibility of becoming Generalluftzeugmeister, it was forced on him, and the fat bastard Göring also shifted the blame on him... but he didn't have the courage to stand up to anyone, either! And instead of confronting the people responsible with the fact that he just wasn't fit for this job or that the failure in the Battle of Britain wasn't his fault, or at least not his alone, he just consumed increasingly excessive amounts of alcohol and meth, which made him even more easily manipulated by Göring, and spent his time privately drawing reaaaally toxic caricatures of his superiors. He was a child in a mans body.

You've taken a very rational look at what was once, to my eight year old eyes back in 1979, a very clear case of "injustice against Heinkel". Perhaps it was, and perhaps Willi Messerschmitt really did have the inside track, but you've given some very good technical reasons why the decision NOT to put the He-100 into mass production and combat service turned out to be for the best. Have you also covered, or would you consider also covering, the He280 in this regard?

Great His tory. loved it. thanx and merry Cristmas.

You have a new subscriber. Very interesting video and analysis!

If I remember correctly this plane was originally a racing plane which is why it's covered in coolant or something like that.

Have yourself some oak leaves with that iron cross. This was a great video.

Excellent documentary and analysis.

Fantastic analysis. Thanks for sharing

One of the most beautiful fighter aircraft

I misread the title. I read wanderwaffle. My appetite clicked before I could.

Very well done and presented!

Thank you. That was very well done.

1:53 Notice the single landing gear, which, although slightly tricky to use during take off and landing, gave the plane a critical advantage in weight and drag, reducing weight by approximately 30kg and thus increasing acceleration by 3415% and top speed by 856mph. True story, I saw it on the History Channel.

That cooling system in the he100 would be far to big for war. 1 hit to the wingtips could have taken out the plane.

I enjoyed that video mate, more of this kind would be appreciated :)

Oh I got a wealth of information out of your video thank you. Henkel 100 that is a beautiful plane thanks man I do appreciate that I gave you a thumbs up

For you Bis, your own Medal - The Order of Leni- umm I mean Iron Cross with Oak Leaves and Swords... yes definitely NOT the Order of Lenin

this was posted on my birthday :D

Excellent. I do enjoy learning new things. Thanks.

You should start your own documentary channel. I enjoyed that. Tanks for the upload.

Liked for the iron cross :p

Built a semi-scale rc model of this aircraft...flew like a dream. Just saying!

I just unlocked the He 100 in War Thunder and was wondering about why it didn't play a larger role in the war. This video more than answered all the questions I had. Thank you for the lesson!

Wow i never thought you‘d actually do a german title :D schön übersetzt :D

wasn't this added in the new war thunder patch?

The bf109 was a good aircraft, but it did have its drawbacks. Limited armament, range, view from the cockpit, especially towards the 6 o`clock was some of the drawbacks. Liquid cooled engine was another, but many aircraft suffered from this - Spitfire, Hurricane, Mustang, Lightning and so on... The bf 109 always climbed very well, from the E-model had fuel injection so it could do a negative G dive, it turned ok, but not as well as the Hurricane and Spitfire, however it seems to have been able to out turn the P-51 Mustand (when flown by a capable pilot). When the Fw190 came onto the scene in late 41 early 42 it "flew rings" around the Spitfire mk V...which may seem strange to some as the Spitfire could easily out turn a Fw. However in aerial warfare speed, firepower and roll is more important than turning, as turning is only usefull if someone is on your tail trying to shoot you, and turning for any amount of time makes you predictable and an easy target for a second bandit coming into or slashing through the fight. The Fw 190 A-models and the P-47 did normally stand a better chance of returning home after hits as they were air cooled, and there are stories of P-47s making it home after pieces of the engine being shot off. I think the He-100 and He-112 might have been better aircraft, the Luftwaffe went with the bf109 and the rest is history. The Heinkel aircraft might have solved one of the major problems of the bf109 and that was its narrow landing gear, which did kill a lot of new pilots.

Well written and put together.

Very informative video and excellent research.
