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.

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

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!

One of the best overviews of propellers I've ever seen. Thank you for your work!

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.

@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?

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.

One of the simplest explanations. Thanks for uploading!

Outstanding ! Ton of information in only 24 minutes and very enjoyable to watch

i can't believe one of the Wright brothers is still alive. we're fortunate to have this explanation straight from the source.

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.

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.

Outstanding guide to how propellers work and why. Thanks for this.

So many lectures have been consolidated in single lecture. Exemples are attractive.

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.

This video is a treasure! Thanks!

Thanks a lot for the video David!

David! Tahnks a lot! Got this as an edited Facebook video, I am pleased to find it at KZread, and complete! Impressive video!

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.

Thanks for uploading this.

The explanation of p-factor is exquisite in its clarity.

This is an excellent, concise explanation.

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 an explanation!!! Very visual (and clear) about the variable pitch influence.

Superb indeed. Thanks for uploading.

This is brilliantly presented. Now I really should study for my english exam tomorrow.

Nice work, this really helped fill in gaps.

Salute to "DAVID WRIGHT SIR" You are a legend😍😍😍 Iam a mechanical engineer and it is very helpful to me. Tq sir

Awesome, old explainations are the best

Its a lot to take in. But it's all the info crammed in. Thanks a million. Answered all my questions.. Thanks

The Animation is gorgeous😍

Holy detail!!!!!!!! that was a lot to cover!!

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!

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! 💥👍🏼😀🙏🏼🙏🏼🙏🏼

Brilliantly explained. So informative.

thanks for the video David, learn a lot about prop aircraft, did not know this much engineering is applied on propellers only

best video which explains various aspect of a propeller

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.

Thankyou for this video. I really enjoyed it.

Until watching this, I didn't realize how critical an understanding of the propeller, in relation to all of aviation, was.

Excellent presentation , need to rewatch to get the things in brain

Perfect video and explains! Thanks.

Im studying aircraft maintenance this helps me a lot because it is a video and not written only in a book

Thanks to you and youtube.

Short precise sentences. I understood every word even though I didn't grasp half the physics.

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?

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

Sorry, if were so well explained, WE wouldn´t need to watch it 100 times more !

that is the most beautiful animation i've seen

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!

Accessible yet highly detailed. This kind of film is perfect for people like me who have more than a passing interest in aerodynamics but no engineering background.

Really really good! Very well explained :)

Thank you Lord for allowing me to find this gem.

Great, genious explanation

outstanding! my head just grew 2 sizes......

May I ask where you found this documentary? I would like to find an HQ version... Thank you!

Very interesting. Thank you

can i get link of the videos describing shock waves. i think there were 3 videos, old fashioned videos?

Best explanation on propellers !

Such a great video thanks!

Helps a lot thanks David

The angle of attack of a propeller blade is generally measured at a point that’s 3/4’s of the way from the hub to the tip. The blade is usually widest at that point and it’s where most of the thrust is produced. To calculate the angle of attack, divide the pitch by the diameter and then divide by 2.36. The result will be the tangent of the angle. Use the arc tangent function to convert it to degrees. For a 69x50 prop, it would be 50/69/2.36=0.30705 and atan(0.30705)=17.069 degrees. The 2.36 is 3/4’s of pi..

This actually visualized the explanation exactly as I need to know... But boy that clicking sound within the video (probably a sound effect of old film rolling) is frustrating... XD I kept thinking my speaker is broken...

nice to remind what i did learn long time ago
