Investigation of airfoil design

Abstract

In this project titled “Investigation of airfoil design” an effort has been made to make a detailed study on lift and drag coefficient of various airfoil sections. Airfoil is an important part of any airplane structure whether it may be passenger planes, jet planes or helicopters. The airfoils decide whether the lift force is sufficient to balance the weight of the plane or not and how much drag force is being applied on the plane. Airfoils are basically divided into two categories, I have tried to differentiate between the two types i.e Symmetrical and Asymmetrical airoils on the basis of their lift and drag coefficient’s variation with angle of attack, stall angle of attack and magnitude of the coefficients. I have also modelled three commonly used airfoil sections namely BOEING737, MIG21 and BELL 200XV which are of passenger, jet and helicopters respectively and tried to study their lift and drag coefficients and the lift force
