This is absolutely stellar. No other word for it. The work behind this must have been monumental.

This is SO incredible. The ingenuity in even a "simple" WWI era aircraft engine is astounding, and really impressive. What a fantastic video!

A treasure.Pure content with none of the glitz or irritating "improvements" inflicted on us by the fatuous Artiste Wannabees on most production teams these days: no gratuitous slow-panning, no breathless fast-cuts, and the soundtrack was actually listenable in its own right instead of being the seemingly obligatory rap-yap. Yay!

Amazing how complex this rotary engine was. The engineering a tooling that went into it was astounding, especially considering the early era of flight.

To use one of the current buzzwords, this video is VERY satisfying. Excellent animation, and even the music was OK, subtle and smooth. Great vid!! I have to amend this comment...each time I re-watch this vid, I am more and more impressed. The animation's parts' actual 'motion' is smooth, and precise. Positions of pieces are logical. The actual 'rendering' (is that the word?, the creation of the images of the pieces) is SO realistic. Texture of the surfaces, shadows, sharpness (threads etc.) great! The text is concise but clear and well-phrased. I was surprised at how 'thin' the carburetors were. I was almost totally unfamiliar with these types of rotating engines, I'd heard of them but never seen one, even an animation, in action.I was literally amazed to watch it rotate, and still find it a little hard to fathom, despite seeing it all laid out. lol All in all, quite an impressive vid.

What a marvelous piece of machinery. And this before the days of CAD and CNC engineering.

Those who didn't liked this video, aren't engineers!!! Such a master piece.

This Clerget Aircraft Engine is over 100 years old.Look at the engineering and details to assemble.I love it!!

Excellent rendering, very impressive! I've been a mechanic for over 40 years and after watching the valve train motion I still can't quite wrap my head around the cam ring operation. The man who invented that was surely a genius!

100% TOP SHOW WOW GREAT MUSIC AND EVERYTHING THANK YOU SIR .

I had heard of this engine before but had no idea how it worked. Thanks for a truly informative and entertaining presentation.

This is an absolutely outstanding animation. Many thanks to the brilliant people who made this!

Having always been facinated by engineering and have rebuilt quite few car engines in the past THAT Mr Jensen was THE FINEST annimation I have ever seen. Absoultely enthralling. I know a little about the clerget engine but I learned so much, I could find an old version strip and rebuild it just from watching the video...Dont know what else to say apart from thank you so much for creating and sharing.

Brilliantly modeled and animated. Huge amount of work.

From harvesting ore from the earth, refining into steel, machining steel into unique parts, and finally assemble them all into an engine. So much detail, effort, and precision for a machine that will be targeted to be destroyed. You can tell a lot about a person even more so with militaries by the weapons they use to destroy you.

Amazing to watch, love seeing how all the connections are made....

Hell of a Bass player in the sound track.

I am building a metal model of this engine and had no idea where the exhaust came out.... this video helped me learn and appreciate the magnificent engineering that went into it's manufacture. Well Done Sir.

Excellent!!! Here it is 100 years after the Great War and these rotary engines are all but forgotten...thank you for bringing them back to life...

Thanks this was my dream wen I was 16 years old and never had the opportunity then I learned DC auto and mechanic diesel and gasoline and now after 45 years is great to look this video thanks for the people who have the time for this

As someone who has both worked on and digitally modeled round engines, allow me to say WOW. You did a great job.

Fantastic Pierre beautifully done regards Tim

One of the coolest things I've seen. An old retired engine mechanic.

This is truly a great piece of CAD work, IMHO! I also think that educational videos like this one are truly educational- on many levels; Allowing countless people to understand the internal workings of engines, that almost certainly, they wouldn't be able to see assembly and disassembly, in any other way.

the CAD work is amazing and I didn't know this engine in the end will start rotating its whole block , great animation !

Now THIS is what youtube was invented for. Utterly astounding work and I can't thank you enough for allowing us to see it Pierre.

Extremely well done. That rotating motor has always amazed the shit out of me.

Never really understood how theses engines worked. This is awesome.. You can really appreciate the engineering in that time period..

Excelente resultado, obrigado! 👏😃. Maravilhosa demonstração.

Fantastic engine, fantastic graphics . . . truly stunning!

Excellent animation. Perfection.

This engine is not only beautiful but pure genius! Wow!

That was awesome I freaking loved it beautifully done really enjoyed that. I can watch that over and over

I quote Englisman French here: "This is just the most interesting and well produced video I have ever seen, the amount of work that must have gone into this gem must have been enormous , I can only say thank you for having the vision to produce this."

A big thanks !!! Finally I understood how it works this kind of motor. Also first time I see a motor moving and the crankshaft fix...

Excelente trabalho! Merecedor de premios de animação e CAD! E a música perfeitamente adequada. Trabalho para ser guardado como um jóia preciosa de explicação, demonstração de funcionamento e montagem!! Parabens à toda equipe de trabalho!!!

That was fantastic, well done!! Absolutely love these engines and their mechanical workings.

The best animation I ever seen..A huge thumbs up!!!

I mean...how come people came up with this in early 1900’s?!?! Simply unbelievable engineering....

Great animation, helped me get my head around a few complexities !. Thank you.

Really very impressive. Useful for students and teachers of technical and engineering courses.

A really complex engine. Great animation.

This animation is incredible...at least I think it is animated. FANTASTIC! Many thanks. I never realized how many parts were inside a rotary engine. Saw a few run and fly at Old Rhinebeck, NY airport many years ago. Watch out for the castor oil. It lubricates the intestines as well as the engine!

Very very nicely done tech video! Been around airplanes since about 1953. Dad was in the Air Force and we flew from places like Rio to the U. S. in recip engined planes. I did not fly in a jet till 1967. I worked near a U.S. Air Force base during my career as an engineer at White Sands Missile Range in NM and saw many old recip engined bombers at the Air Show and Family Days at Holloman A. F .B. Your video brings smiles to my face and a song to my heart!

I love ROTARY engines.Been a military aircraft buff since childhood and the ROTARY engine has always fascinated me.Thanks for sharing man,I love this stuff.And the video...awesome and informative.Excellent work brother.

Very professional and slick... well done. Thanks for posting this Pierre, loved it.

sounds like a gatling gun at the end- excellent production. A moving Haynes manual !

As primative as this engine was, it still was machined and assembled with great precision at a time when most roads in America were dirt and cowboys still had a job.

It isn't often we see attention paid to rotary engines. A fine piece of work.

This is wonderful - I'm going to show it to my engineering students.

Outstanding simulation, and fitting music.

Absolutely beautiful. I can’t even imagine the pain staking effort that went into this production.🤙👍

Perfect video !!!

That's one insane motor! Thanks for the hard work making this video! It must have taken forever!

I thing it was wrong when I see the main body rounding, but I found a video of a real one working... amazing!

beautiful video, I can only estimate the amount of hard work has gone into making such a fine content. thank you.

Brilliant thanks for all the effort

finally a youtube video with great music

This video is absolutely phantastic ! ! ! nothing more to say !

>> Merci Pierre >> une merveille de technologie française d'il y a + de 100 ans!!

what kind of animation is this ? blessed with it man

Accurately depicted and skilfully made. Great job!

Es realmente increible la forma como explica el.mecanismo de este maravilloso motor, gracias por permitir conocer su funcionamiento.

This is the best video i have ever seen on UKposts. Just cant imagine how much hard work is there behind this video . Amazing my friend 🖒

Excellent tutorial video and amazing 3D modeling, I am trying to create the 3D models in Solidworks even it is too hard for me. I am a big fan of the Warbird and the work you have done helps me a lot, thank you very much and I am appreciate your impressive work!

Excellent, and the music was perfect. Some cool jazz....😎

Un chef-d’œuvre. Du grand art ! Merci Monsieur.

I am lost for words here ! This is just the most interesting and well produced video I have ever seen, the amount of work that must have gone into this gem must have been enormous , I can only say thank you for having the vision to produce this. Unfortunately the morons that insist that the engine does not rotate on a rotary engine will not see this video, they should be forced to watch it, not that their miniscule brains would comprehend what they were seeing ! Very Many Thanks for posting this!

Exelente video de un motor de un aeroplano ......saludos desde MEXICO....

Merveilleuse! Outstandind production, really showing the complexity of these motors in proprer detail.

One out of a million videos of this kind.

Vídeo muito bom e informativo, eu sempre quis saber como funcionava um motor desse, só não imaginava que era tão complexo. Obrigado por nos ensinar, parabéns pelo vídeo!!!

Incredible engine, to think that technology advances in great steps

Amazing. Phenomenal work!

Fantastic precision. Great presentation. Thanks a lot.

Outstanding work on the design, and especially the assembly animation. One of the very best that I've ever seen, and, I'm saying this over 5 years after your original release. Thanks again, SCR

beautiful

Absolutly fantastic !!!!!!!!

This is an amazing video. It shows the design elements very well. All of that designed with paper and pencil.

Thank you very much for an outstanding video. I could watch that 100 times

This engine was invented, assembled, then put in use over a 100 year ago

It's amazing engine technology.... stunning

Great job putting this together.

Fantástico trabalho de projeto e animação. Mas balancear um motor desses com toda essa massa girando devia ser uma coisa de outro planeta!

Très beau reportage pour ce remontage.... Il fallait une précision incroyable aux machines d'usinage pour obtenir la précision voulue dans les ajustements.... Beau travail.

Rett og slett fantastisk, en god opplevelse.

Thank you 🙏 i have seen it,never work on it! Looks great 👍 simple with lots of bearings ,fascinating full engine turning ☝️for cooling system 😂👏👏👏👏👍

Brilliant video, amazing and instructive. Thanks.

Amazing CAD work. I really appreciate the time you took to model this and the assembly.

Absolutly every part of that rotating assembly would have to be balanced perfectly even the exhaust manifolds.

I vote for most excellent video and audio 👍 on UKposts.

Awesome video, thank you

Спасибо.

fantastic cgi!thanks man ,greetings from serbia

Superb! Thank you very much.

My dream now is project engines like This

Congratulations for the incredible work! Excelente movie!

Coolest visual explaining, and coolest music too ! Top quality production - well done .

Amazing technology of 1900's,I wonder how this is possible

Amazing n very complicated👍
