Question 1

What is Moment Coefficient in Thin Airfoils about?

Accepted Answer

Okay, here are the calculations based on the thin airfoil theory:

* Lift coefficient: 
   - Lift slope from theory is 2π
   - CL = 2πα = 2π(5°) = 10π ≈ 3.14

* Moment coefficient about leading edge:
   - cmLE = -πα/2 = -5π/2 ≈ -1.57

* Moment coefficient about quarter chord point:
   - From theory, this is zero.

* Moment coefficient about trailing edge:
   - cmTE = cmLE + CL = -1.57 + 3.14 = 1.57

So in summary, the coefficients are:
CL = 3.14
