Excellent video! Thank you very much. Two decades ago I made the unfortunate decision to go into finance. Now, I get my fix by going down shamefully deep and twisty aviation and automotive engineering rabbit holes:)

Thanks for for these videos. It is a great resource in the small niche of tailless aircraft design that is largely ignored. very excited to see more of your wing design and how it performs.

I’m so glad i found your channel for a detailed aerodynamic breakdown of these topics for the hobbyist

к большому сожалению у вас маленький опыт и все ваши математические выводы содержат грубые ошибки, которые не позволят вам спроектировать самолет с заданными летными характеристиками . Вы дилетант , который ничего не знает , сейчас во всяком случае.

Damn, this video is insane. Thinks Bro!

Well-done. There's clearly a hunger for this type of content on TH-cam, as indicated by the view counts on this video and your Part 1.

Gabe, thank you for putting these videos together. I'm not an aerospace engineer but I feel like I learned more in these two videos on aerospace than I did in my entire undergraduate program. Incredible detailed, incredibly in depth, absolutely amazing. Looking forward to future videos! Thank you!

Hey mate, would you consider doing a video that is self contained and focused on using diagrams to show that the principles discussed are obvious? I kinda get the math, but I get a little lost in some of the jargon. Making it very intuitive would be huge!

What program are you using to simulate the flight characteristics?

u teach better than my professor

16:46 does increased speed really increase induced drag? As far as i know the ind drag coeff drops with the velocity as the AOA decreases, so can we be certain that drag as a force raise?

amazing content!!!!!!!!!!! thank you so much for sharing your knowledge with us!!!!

Pretty good video. Will there be another one in these series? Have you considered doing one on box wings?

Hi, whats the reference area for planes in the drag equation? Generally in cars we use the frontal area but a lot of papers are saying that its the wing area for planes? What is actually the reference area

By far, the best video on TH-cam on aerodynamics topic! Thank You for your work! Please continue! Waiting for new detailed series on dynamic stability and winglet design!

can u mention some books to learn this?

Such a high-quality video. Thanks to Gabe, a message from a Taiwanese student who is also majoring in aerospace engineering

🎉🎉🎉 great video

I haven't taken aero yet but I learned so much from this video.

Hello sir

Your series is great at explaining the process to go from design tasks through formulas, to virtual models ending with a working test model. I appreciate the depth in this series. I have successfully built a RC Prandlt-D flying wing (no vertical surfaces.) from foam board, as tested and detailed out by Albion Bowers formerly at NASA years ago. I have been trying to simplify the build process so other can easily succesd too, this has been helpful on the quest, thank you.

How i Contact with you

Hey thanks a lot! I am working on an autonomous drone for data collection at variable altitudes, the initial plan was a flying wing but some difficulties in balancing made me choose a more traditional model, at least until the software is developed enough to control the instability of the aircraft in flight, as my area is physics not engineering I knew how it worked but I had no background on how to make it work for my particular purpose, this video made me rethink and revert the model back to the original plan as it was more efficient than the aerodynamic abomination that I'm using now, a brick with wings and a turbine strapped to its back would be a good description of what I've created

Induced drag decreases, not increases with increasing speed. Di = L^2/(πqb^2) or CDi = CL^2/(πA) with q being dynamic pressure, b the wing span, and A as aspect ratio (b^2/wing area).

O melhor trabalho sobre está configuração que já encontrei. Gostaria da indicação de literatura útil para o desenvolvimento de aeronaves deste tipo.

What sort of Cd are you aiming for with this wing? I am personally designing a speeding with a Cd of 0.05 and am currently at 0.083 Edit: can you please help me out a bit? I am currently using a mh60 airfoil with no twist, naca 009 winglets and a frontal area of 0.00876m^2

Thank you man ❤

Looking forward for whats to come!

Hi Gabe, another fantastic video! You are a master of this! So quick question, can you recommend a top couple of books to cover this in some approximate way to how you do here? Or stated another way, what do you recommend in books? Also, I’d like to recommend taking a look at the “Klingberg wing MkII” channel. He has done some really interesting analysis of a famous flying wing failure and his most recent videos have isolate a really interesting root cause phenomena related to Reynolds Number that is really a core lesson in the vagaries of aerodynamics that I think really highlight some of the things you say about verification.

Thank you so much for including the explanation of stability derivatives. Looking forward to the other videos!

This design will be very, very spin prone due to size, shape, and location of the elevons.

Excellent series! I'm really looking forward to your winglet analysis! I used to make rc wings and have test flown all kinds of weird shapes and angles to dampen adverse yaw but I've never seen the variables and their relationships explained so well. Keep up the great work!

Good stuff, would love to see how you counter adverse yaw, and produce directional control.

Very good video. I need more content like this!!!

The fastest glow up since Mr Beast

Think three forward and backward .

Plz continue the series it is really helpful

incredible videos! love the detail

Subbed for this level of details Keep going mate

subbed

As someone who had a small Module about flying robotics and fell in love with flying wings, this vid is really awesome! Thanks man. :)

Dude plz, maybe can you look into upside down v tails

This one is too theoretical for me. I wish you dived more into practical side of things that can be applied by hobbyists like me

Both parts are top notch content, thank You very much!

Great series so far, really enjoying the videos keep making them and you'll blow up

Hello Im an Inventor invented a fishtail propulsion for the flying wing. Instead of an reflexed airfoil , tandem airfoils are used. One big front airfoil is the fish body. And the small airfoil behind is the fish tail fin. The tail fin is working like a slotted flap And it's producing thrust like a propeller. It decreases drag of the big body front wing with boundary layer suction technic. Im searching for people interested in my inventions. I believe fishtail propulsion is a very efficient flying technic.

Thank You for your effort putting all this information in the video! Waiting for the next part!

where next video? :(
