In this project titled investigation of airfoil design an effort has been made to make a detailed study on lift and drag coefficien of various airfoil sections. The chord line is the straight line connecting the leading edge of the airfoil to the trailing edge. The system consists of a series of 4, 5 and 6 digit airfoils.

Air acts in various ways when submitted to different pressures and velocities;

All of the airfoil parameters such as maximum lift coefficient, angle of attack at stall, stall behavior, pitch moment, extent of laminar and turbulent flow, and the location of airflow separation are. See also, michael cavanaugh, paul robertson and w.h. The answer turned out to be surprisingly simple, but led to a new, and somewhat tricky, design consideration. All of the airfoil parameters such as maximum lift coefficient, angle of attack at stall, stall behavior, pitch moment, extent of laminar and turbulent flow, and the location of airflow separation are.
