In this 4th video in a series of 4 about airfoils, we search for a physical understanding and interpretation of the coefficient of moment “Cm” of airfoils. This parameter is often confusing to grasp at first, but a physical understanding of it helps us to select airfoils, planform layouts and incidence angles for the wings and stabilizers&control surfaces of our aircraft that we’re designing in SOLIDWORKS to assure that it can fly in a stable manner.
Look out for the next series on stability! We’ll apply what we learned about airfoils to get a physical understanding of stability of the aircraft as a whole.
