An Aerofoil (also known as an airfoil) is a specialized shape designed to produce aerodynamic forces when air flows over it. It is typically used in a variety of applications, from aircraft wings to turbines and other high-performance systems where control over airflow and pressure distribution is critical. Aerofoils are designed to optimize lift and minimize drag, which are key factors in ensuring efficiency in various aerodynamic applications.

Key Features

• Shape: Aerofoils are designed with a curved upper surface and a flatter lower surface. This curvature helps in managing air pressure distribution around the foil, generating lift while minimizing drag.
• Leading Edge: The front part of the aerofoil, known as the leading edge, is typically rounded or sharp depending on the design requirements. This edge plays a critical role in initiating the airflow over the surface.
• Trailing Edge: The rear end of the aerofoil, which is tapered to allow smooth airflow separation, reducing turbulence and drag.
• Chord Line: The straight line connecting the leading and trailing edges of the aerofoil is known as the chord line. The length of the chord is crucial in determining the aerodynamic properties of the aerofoil.
• Thickness: Aerofoils vary in thickness depending on the application. Thicker aerofoils generate more lift but may also cause more drag, while thinner aerofoils are more efficient in reducing drag.
