You explained the instructions really well, thank you.

You keep saying further, but mean farther. (i.e. The gas station is farther from my home is an imperial measurement.) (i.e. He is spiritually further ahead in life than I am, cant not be measured with imperial measurements) I hope this helps.

The lower the Reynolds number, the more it’s like swimming through thick soup.

Faster and larger we can get planes the better and farther they can fly 🤙

Thanks for making these. I appreciate someone explaining the design instead of trying to entertain me with jokes etc.

What about the scaled travel ratios ? If we throw 1x and 2x scaled planes, measure their distance and divide the distance of larger plane by 2, would it give the same result ?

Very interesting!

Thanks for detailed instructions on building airplane. I liked it and ordered foam board. Unfortunately the length of foam board was not sufficient to take out 30" wing. So I created airplane with 15" wing length and divided all measurements to half. But I ended up making heavy airplane which was sinking too fast and couldn't glide. I checked the wing cube loading and found it to be 25 :) Restarting from scratch.

You’re amazing

We need more videos, good stuff

Keep it up I really appreciate it Just one thing Next time name or number the episodes because some people use to downlaod these videos

Nice man!

Very much impressed by your vedios

Is there your vedio on how to install mini moter on these gliders

Henceforth I shall use the Reynolds Number in arguments against puny 'stealth' planelets activists, advocating instead for BIG ASS supersonic interceptors for long range fleet security (F-111B, F-14B and their fictional modernizations)...

bro where are the next videos?? I am really invested in them.

What, if any, effects would Reynolds number have upon spin recovery? Search Medium for “going beyond procedure - an open letter” perhaps adding “light twins spin” to the search and see the single engine PA-28 discussion further down when looking at Catherine Cavagnaro’s discussion.

Thanks!

Nicely done. I've been looking for exactly what you're doing. Thanks.

Great video 👍🏻 Relax and smile 😎

What a wonderful channel. Subscribed. Have you calculated the reynolds number of your tache? (I don't know why I felt compelled to ask that)

Are the weights of those 2 different size planes scaled equal to their size difference?

Very nicely presented! Clear and understandable.

Brownean motion. That explains Reynolds number.

*I sent a link to your channel* --------- to Boeing ---------- *Hope they learn something* 😉🙂😊

Yea OK got that, Hmm, yea that too, wow did not think that, but then at 4:47 he said making planes bigger makes them more efficient… What ??!!?

wow great stuff. I shall now watch every single one of your videos

try to relax a bit in presentation. it looks like you're trying to blow up my head with your mind. 👍

Great information. Thank you.

Great vid. Thank you. Si, Christchurch, NZ.

That was good. Thanks.

Reynolds numbers are important. The standard atmosphere as lower Reynoldsnumbers at increased altitude from its own. Climbing to altitude with the same indicated airspeed, e.g. Vx, the Reynoldsnumber decreases slowly. This reduces the glide performance of the craft, the L/D reduces a little. The now obsolete Boeing Condor, a long endurance high altitude platform had an L/D of 44 at sea level. At 20.000 m the L/D was 39. This was a Reynoldsnumber effect. Flying high is a quest.

5 minutes in one sentence: Small things moving through air (e.g. bees) see it as sirup. Large things (e.g. B747) see it as a fluid like water). Hard to explain, I also needed time to understand. Running through my fathers garden with a Airfix model in my hand I wondered: he is small, the real aircraft big, the air is the same. How does the model aircraft feel the air? Doing my batchelor, and later master in aviation, it was eventually explained.

lift to drag ratio must be worsened by speed, fast planes can't match the 50:1 glide ratios of slower gliders

This is also the reason why a smaller plane has to be much more aerodynamically precise than a much larger plane. Thanks for sharing! Please have an excellent and awesome day! ☀️✨🌟✈️

thank you airplane sheldon

I don't understand.😢

Hi, do you have a template of the pieces and sizes? Do you have a set of instructions or steps written down to follow. I really enjoyed the video and would love to try it myself. Thanks

I always wondered how Reynolds number affected wind tunnel modeling of airfoils. The Wright brothers were the first to empirically study airfoil lift and drag efficiencies through wing tunnel modeling, and as you have stated, lift coefficient is not significantly affected by Reynolds number. This is why their experiments to find the best lift characteristics using extremely small airfoil models in a low velocity wind tunnel were successful.

Parasitic drag not parasite drag

wow

nice glider!! i have a question. what thickness is the foam sheet?

I am already decently experienced with designing aircraft in flyout and simpleplanes (simpleplanes is a game about making planes while flyout is more akin to software), but this video opened my eyes to advantages and drawbacks of wing loading among others

Thanks for taking the time and effort of making these videos and sharing your knowledge!! Best regards

Perfect

Thank you ❤

Great explanation thank you very much. Can someone explain to me, why some Americans develop vocal fry ?

Thank you, well explained. I asked many people who studied aeronautics at the university and so far no one was able to explain it to me so that I could understand it. Now you did that in 5 min. You did a great job. Now I got it.

Discovered Reynolds analogy in 1971 when I tried to design a paper airplane for the UCLA Engineering week paper airplane contest. It can be discussed without numbers. Basically as airfoil get smaller, the viscosity of the air becomes more important than inertial forces like lyft. That led me to use an auto gyro design that was very small with no camber. This about 3 inch tall auto gyro flew 3 times longer than 2nd place. Latter I made 1/2 inch tall auto gyros from vellum using surgical tools. These stayed aloft very long. The problem was they had to be handled with forceps and were easily lost.

Wasn't the bigger aircraft heavier, thus starting with more energy?
