Confusion about calculation of aerodynamic moments

Click For Summary
SUMMARY

The aerodynamic moment for an airfoil is calculated based on the pressure distribution over the airfoil surfaces, specifically focusing on the lower surface. The formula presented in "Fundamentals of Aerodynamics" by Anderson details how these moments are derived from the forces acting on the airfoil. The confusion often arises from the reference point about which the moment is calculated, which can vary depending on the analysis. Clarification of these concepts is essential for accurate aerodynamic analysis.

Hello,

Can anybody explain how the aerodynamic moment is calculated for an airfoil ?
I was reading the first chapter in "Fundamentals of Aerodynamics" by Anderson & the formula for aerodynamic moment for the lower surface of the airfoil confused me. Is the aerodynamic moment calculated about some other point for the lower surface ?
Thank you.
 
Physics news on Phys.org
need more information like page where to find in that book?
 
no need now, i figured it out myself. was just interpreting it wrongly.
