True. In a way I often think those old guys had the ability to teach better with those technologies than today's youtubers with this generation's graphic skills probably because those videos were made or supervised by actual technical professionals.
Love these old docs. No silly music. Just straight up, well presented facts with no dramatisation or wow factor in the voice of the narrator like you often find these days.
Created by the RAF’s Tucano Course Design Team, based at RAF Scampton. Sqn Ldr Pete Dummer and Wg Cdr Pete Stannard were the brains behind it and came up with the storyboard. I did all the boring start up and taxi stuff for the film crew. Pete Dummer and I did the flying sequences. These were filmed from the back of a Hercules over the Vale of Evesham. The animations were fantastically expensive to do way back then!
I did my bachelor's in mechanical engineering and have decided to step up my game to aerospace engineering and find myself confronted with a tonne of kowledge gaps and lack of intuition in a lot of concepts my peers take for granted. Seeing that little animation at 4:26 just made everything fall into place beautifully.
Probably the best video/documentary which explains various aspect of a propeller with interesting historical facts. The best part is the animation which explains propeller stuffs in the best possible way. Thanks a lot team!!
I at this moment I can only say THANK YOU ! Such clarity.. Straight to point...no stupid act no bullshits only pure info right on the track from start till end ! I love you !
The best propeller subject I have ever watched! I am doing my CFI and this is going to be with all my students now! Love and really enjoyed! Thank you!
There are no better educational aids than these old school instructional videos. This was tremendously helpful in helping me understand propeller principles. Thank you!
One of the most informative videos out there about an extremely large amount of aspects of a propeller. It explains many concepts, and does it using a method that is easy to understand, but informative at the same time. It does not bore you with unnecessary information. It provides interesting facts to make the learning more immersive and uses a chronological order as an attempt to make the information make more sense, be easier to understand. I recommend this video to everyone who even has a mild interest in aerodynamics or airplanes in general, and even if you don't, I still recommend you give it a watch.
I am doing my degree at the moment in AME (Aircraft Maintenance Engineering) and this video helped me a lot to understand the principal of propellers and the different stresses forces acting on them.
Wow. I have no aviation experience other than youtube binge-watching, and I watched each bit 10 times over before I understood the diagrams, and now I feel like I read an entire textbook on the subject in this video. Absolutely amazing production and visualisation! Best use of my time today.
Thank you for sharing this amazing video.. short, to the point and packed with useful information. I like how it's not dumbed down like today's documentaries.
This is really a fantastic overview of how a propeller works and why and they do what they do. The most helpful part of this video is the explanation of p-factor (which here is called asymmetric blade effect) that starts at 19:03. The film talks about p-factor only affecting tail-wheel airplanes during take off and that is correct about takeoffs. However any general aviation single propeller aircraft can be affected in flight by the leftward tendencies induced by p-factor when propeller axis is above the direction of flight then there will be some p-factor and will be most strongly induced during low airspeed with high pitch angle such as during initial Vx climb.
I'm interested in flying but this just flipped my brain upside down... .-. I'm gonna have to get a notebook and watch this like four more times to understand the logic lol.
Sk8boarder1700 please keep skateboarding and don't consider flying... this is BASICS of prop ops. If you don't understand this concept, good luck with the more complex aerodynamics....
Alexandre Reber When I watched this it was like 4am chill out dude. Anyone can talk shit over the internet just shows how petty you are over a RUclips video lol
Don't worry. This is more for people who are into designing aircraft. You just need an overview if you want to simply fly. Go learn to fly and have fun. Don't listen to people here yu say otherwise. They probably have not designed a single aircraft in their life but want to feel superior by putting others down
Props should push - because of the Bernoulli effect: the air the accelerate forms a narrow tube behind them, which is fed from a "fanned out" incoming cone of low-pressure; so sticking the fuselage in the way of the output is the worst possible thing you can do (reduces efficiency and exponentially increases friction), whereas putting it in front instead is doubly more efficient (reduced friction, since the air is already being drawn in from a wider angle). The missed out discussing airfoil sections and the reynolds number: the shape of the blade root near the hub, verses the midsection, versus the tips, is all dramatically different. They also forgot to talk about induced drag - the vortices at the blade tips where the high-pressure underside air rushes in to take the place of the low-pressure topside air: if you hold a bit of string at the side of a moving propeller, you will find the air is blowing the *opposite* direction to what you might think!
As others have said what a fantastically clear documentay, today's content producers could learn so much from this, content is key, not thumping background noise. By the way any idea who the narrator is? Many thanks to all concernd in making this piece.
I am now at 6th minute but I couldn't hold myself to wait till end; this explanations and illustrations are AMAZING. Thank you so much for this upload.. Regards
Wow this is a great video explanation thank you for posting this !! I had such hard time understanding aoa in relation to flight, this helped so much! 💥👍🏼😀🙏🏼🙏🏼🙏🏼
Wow, the way the oldies explain aviation related information is much more clear! Does anyone know who made this lesson and where I can find more of them?

God, the graphics here are so cool. I love those old wireframe-laser graphics.
True.

Yes, these are incredible. How were these graphics designed/made at the time?

Is it a series available for download? I'm a physics student. And this stuff is gold
Really miss this kind of graphs today. They really helped me to understand a phenomena that I couldn't understand watching modern videos.
Thanks a lot for this
Badass!! Thank you!
One of the best overviews of propellers I've ever seen. Thank you for your work!

could i fly your plane
@@Iugeer don't see why not

I at this moment I can only say THANK YOU ! Such clarity.. Straight to point...no stupid act no bullshits only pure info right on the track from start till end ! I love you !
And no annoying music!
i watched this four times. Full of information Great salute to Mr.DAVID and the Engineer who developed this video.
The best propeller subject I have ever watched! I am doing my CFI and this is going to be with all my students now! Love and really enjoyed! Thank you!
Ma'am can you give your mail id?
Excellent. I had to watch it a few times to understand it.
Sorry, if were so well explained, WE wouldn´t need to watch it 100 times more.
@@andrerovigatti9997 That's like blaming your teacher because he didn't teach you well enough so you didn't have to study for exams.
I wondered who would be the first to admit that.
@@ThomassoCZ THIS
@6:10 why does the angle of attack increase at the tip, thus requiring a twist? Is this increase caused by the larger relarive air flow?

So many lectures have been consolidated in single lecture.
Exemples are attractive.
i can't believe one of the Wright brothers is still alive. we're fortunate to have this explanation straight from the source.
I am doing my degree at the moment in AME (Aircraft Maintenance Engineering) and this video helped me a lot to understand the principal of propellers and the different stresses forces acting on them.
Where are you working brother?
Wow. I have no aviation experience other than youtube binge-watching, and I watched each bit 10 times over before I understood the diagrams, and now I feel like I read an entire textbook on the subject in this video. Absolutely amazing production and visualisation! Best use of my time today.
now you can study it for real
One of the simplest explanations. Thanks for uploading!
Outstanding guide to how propellers work and why. Thanks for this.
Outstanding ! Ton of information in only 24 minutes and very enjoyable to watch
Thank you for sharing this amazing video.. short, to the point and packed with useful information. I like how it's not dumbed down like today's documentaries.
Wow! This was so informative. I wish modern documentaries were like this. so much information thoroughly explained in a short video.
Very informative and interesting as well. Thank you for posting.
One word: BRILLIANT!!!
Thank you.
Absolutely beautiful documentary. Thanks
Holy detail!!!!!!!! that was a lot to cover!!
What an explanation!!! Very visual (and clear) about the variable pitch influence.
Great explanation. Even my CFI said he had trouble relating to the changes in pitch til they were compared to car gears.
Thanks a lot for the video David!

Very clean and comprehensive explanation with good narration and graphics.
This is brilliantly presented. Now I really should study for my english exam tomorrow.
The explanation of p-factor is exquisite in its clarity.
This video is a treasure! Thanks!
Much appreciated. Just great.
Nice work, this really helped fill in gaps.
Thx a lot for an excellent technical video. It answered many of my questions and more! Cheers!
Superb indeed. Thanks for uploading.
This is an excellent, concise explanation.
Wow! Very informative, clear explanations. I never realized that there are so many forces acting on a prop !
wait for helicopter main and tail rotor forces explanation
The Animation is gorgeous😍
David! Tahnks a lot! Got this as an edited Facebook video, I am pleased to find it at RUclips, and complete! Impressive video!
Awesome, old explainations are the best
A beautiful feat of practical engineering. hats off to those genius pioneering brains that made it possible for us to have what we have today.
Sucha freaking informative vid... literally got so much to understand and knw in just one video
WHAT A GOOD DOCUMENTARY WELL PREPARED
Brilliantly explained. So informative.
0:11 Wright invented the 1st usable plane and the 1st Aircraft carrier launch system, what a smart bros.
Also: first cruise missile was built on basis of their aircraft.
Very informative! Thanks, for uploading.
Helps a lot thanks David
...best explanation available. Thanks
Thank you. I always wondered how a propeller could lift an aircraft off the ground. Now I can prepare for the DBF competition.
dayummmmmmmm
Where are more videos like this one? I'll watch all of them!
Brilliant. I'll have to watch it a few times to get it straight.
Truly Amazing
This video documentary has propelled me to new heights. I've been spiralling in circles with them for years since learning to fly! - Well Done....
Roland , you're spiraling alright , and teetering hahaha just kidding

Salute to "DAVID WRIGHT SIR"
You are a legend😍😍😍
Iam a mechanical engineer and it is very helpful to me.
Tq sir
very informative video' Old but Gold!!!

Thanks i learn alot ,now i can go back to my model drawing board and decide what i want to achieve for flight...
Yeah, did you
Excellent presentation , need to rewatch to get the things in brain
nice to remind what i did learn long time ago
When a super old documentary teach you way more than anything new that you can find.
The opening song is my new favorite song. ❤
Nice track at the end.
thanks for the video David, learn a lot about prop aircraft, did not know this much engineering is applied on propellers only
Thank YOU!!!
Why was the Cessna pilot sweating?
His fan stopped working.
HA!
that was actually funny
😂😂😂
lmaoooo that little fan
Very interesting. Thank you
Great, genious explanation

best video which explains various aspect of a propeller
Interesting video. Nice explanation. Thank you.
Great, clear commentary no music
Such a great video thanks!
Thankyou for this video. I really enjoyed it.
this video is on point, i was wondering how front propeller make the plane fly (lift or drag)
Im studying aircraft maintenance
this helps me a lot because it is a video and not written only in a book
Brilliant explanation! 👍
Best explanation on propellers !

Its a lot to take in. But it's all the info crammed in. Thanks a million. Answered all my questions.. Thanks
Excellent!
Thanks David.
The best video I have ever watched on propellers
Awesome documentary, 10/10. Love the graphics, simple n effective. Id really like to know what hardware it was made on.
Well explained, a sound physics lesson.
I have learned a lot! Those graphics are really great. I really understand the reverse thrust. I had it wrong in my mind.
That was a great video, thanks!
i learnt alot more than i thought i would, i can actually apply this in my flight sims
anyone remember the aviation documentary series from the late 1980's called reaching for the skies? The reason I ask is because that series used to have the very loud sounds from the library footage - just like this does. And the narrator sounds familiar.
A Whole Textbook
Thanks Mate!
that is the most beautiful animation i've seen
fascinating... thank you...
