ABSTRACT
The desire for good aerodynamic characteristics in various airfoil designs has necessitated the
adoption and the use of the numerous researches and engineering testing models in order to
define and improve on their performance. This study focuses on determining the lift and drag
coefficients at various angles of attack. The drag and lift coefficients are determined analytically
used the obtained data. The variation in the coefficient can be accounted by the change in the
angle of attack. This correlation between the angle of attack and the coefficients is
comprehensive discussed herein as well as its effect on the airfoil lift and drag. In pursuit of
establishing and demonstrating the vehement link between the aforementioned parameters,
graphical plots and presentations regarding the lift and drag coefficients at various angles of
attack are utilized.

INTRODUCTION
Design for good aerodynamic characteristics is one of the most fundamental considerations in
any design of any kind of airfoil. Thus, the phenomenon of the wings of the birds, over time, has
gradually inspired the design of airfoils and consequently triggering numerous studies on the
performance of airfoils. This has served as an impetus for the development of a variety of airfoils
in order to optimize the lift, drag and stalling characteristics over a vast range of speed and
through a variety of fluids.
The numerous studies concerning airfoils has expended the development of various theories such
as the thin airfoil theory, the Bernoulli’s theory of flight, Newton’s theory of light and many
more.
The Bernoulli’s theory of flight is the most commonly deployed theory in the analysis of airfoils
and it states that: for a non-viscous, incompressible fluid in steady flow, the sum of pressure,
potential and kinetic energies per unit volume is constant at any point. Ignoring the potential
energy due to altitude it becomes the Bernoulli’s principle which states: when the velocity of a
fluid increases, its pressure decreases by an equivalent amount to maintain the overall energy [1].
