Aerodynamic center, Center of pressure, Moment: Can I use Quarter chord for designing airplane ?

Aerodynamic center, Center of pressure explained clearly and intuitively for low speed and supersonic speed.
Run CFD to find AC please don't use quarter chord for designing.
Correction: "Moving towards the rearwards" change to "moving towards the leading edge"
anyway the Center of pressure changes with angle of attack

Perhaps just me. The visual elements are so distracting I cannot watch the video. Your information is complex and requires the viewer to concentrate on the material you are presenting.

He is barely literate in English.

Thank you for the explanation. Do you perhaps have a video on how te estimate center of pressure using CFD software?

[@gokmen9928]

Amazing accent. Marvelous..

[@aerodynamico6427]

"See-zaw"????

[@aldopolgeo73]

Unclear explanation. English is difficult to unferstand.

Which part do you feel like that? or the Whole video?
I will try to correct that ...

@@aerodynamicsinminutes2201 Hi, thanks for asking. This is my opinion:
1. Graphics are good
2. Video logical sequence is good
3. Since you have accent, you have to speak slower and gesticulate more with your mouth when pronouncing so the words can be understood easily (there are parts where you speak at an adequate speed).
4. The term "chunks of area" sounds strange, and by the time the person watching the video understands what it means the video is already way ahead and you feel confused. Maybe "slices" will do better, or better yet, take a few more seconds to explain what an area chunk or (slice) mean.
5. I believe you need to explain better why the center of pressure moves backward with the angle of attack and why you cannot use it for calculations if it does (after all, the center of gravity also changes with configuration -but less so, and only minimally in flight). Maybe a few more graphics to explain the concept would help.
6. Adding a a couple of minutes to the video for clarity purposes is acceptable, after all what you explain is usually poorly explained in books too.

I liked your response. If it would be someone else, he would counter argue but instead, you just accepted and thought of correcting for the sake of self-improvement. This is a sign of a wonderful personality. I congratulate you 👏@@aerodynamicsinminutes2201
