I had a question: why would coefficient of moment for a wing matter when there would be a much more significant moment generated on the whole aircraft due to center of pressure and Cg? Does Cm of the wing itself play a significant role in the aircraft's overall stability?
Great question, and yes, for conventional aircraft the stability is dominated by the position of the horizontal tail and main wing relative to the CG. The change in pitching moment as a function of angle of attack from the airfoil will affect stability, but only slightly as you point out. However, the pitching moment on the airfoil (and therefore the main wing and horizontal tail) do affect the trim condition. This is especially apparent for flying wings, some of which use reflex trailing edges to adjust the pitching moment of the airfoil/wing for trim purposes. Does that help?
@@AeroAcademyOnline Yes! Thank you so much for the response! I didn't expect to receive an answer and didn't realize that you posted this (UA-cam didn't give me a notification). I am done my final now and thankfully I passed, but thank you for your explanation sir!
The authors have two wrong scientific approaches: researching the creation of Lift force and Low pressure at upper side of the wing, relative to the ground surface and Earth. I explain the aerodynamic cavitation and existence of Lee side aerocavern, and creation of Aerodynamic force. Low pressure creates force normal to the cord (contact surface), and it name is "aerodynamic force" because is made from the air (aero) in motion (dynamic), or wind relative to the wing (object).
Thank you for your videos! These have been a great help towards my Senior project

Thank god I found your video! The best explanation I've found so far
thankyou sir
