2. ABSTRACT
• Airfoils are the cross-sectional shape of an aircraft wing or propeller
blade that is designed to generate lift and reduce drag.
• The design of airfoils involves the use of computational fluid
dynamics (CFD) simulations and wind tunnel testing to optimize
their shape and performance.
• CFD simulations allow for the prediction of fluid flow around the
airfoil, including the lift and drag forces it generates, while wind
tunnel testing provides experimental data to validate the simulations.
• Data on various airfoils can include information on their shape, lift
and drag coefficients, and performance at different speeds and angles
of attack.
• This information can be used to design new airfoils or to improve the
performance of existing ones.
3. INTRODUCTION
• An airfoil is a shape that is used to produce lift when moved through
a fluid, such as air or water.
• Airfoils are used in the design of aircraft wings, hydrofoils, wind
turbine blades, and other applications where lift and drag need to be
optimized.
• The shape of an airfoil is designed to produce a specific amount of
lift and drag depending on the intended application.
• The lift force is generated by the difference in pressure on the upper
and lower surfaces of the airfoil, while the drag force is generated by
the friction between the fluid and the surface of the airfoil.
4. OBJECTIVE
• To design and analyze high-performance airfoils using CFD
(Computational Fluid Dynamics) and CAD tools to improve
aerodynamic efficiency, specifically focusing on lift and drag
characteristics at various speeds and angles of attack.
• This is supported by the usage of simulation tools like ANSYS
Fluent, JavaFoil, and CATIA V5.
• In summary, the project aims to:Design airfoils using CAD software.
• Analyze their aerodynamic performance using CFD simulations.
5. HISTORY OF AN AIRFOIL
• Aerofoil or airfoil is a cross-sectional shape designed with a curved
surface, giving it the most favourable ratio between lift and drag in
flight.
• Lift is the component such that the force is perpendicular to the
direction of motion, and drag is the component parallel to the
direction of motion.
• A similar idea is used in designing hydrofoils, which is used when
water is used as the working fluid.
• Aerofoils are highly efficient lifting shapes as they generate more lift
than similarly sized flat plates of the same area and generate lift with
significantly less drag.
6. AIRFOIL TERMINOLOGY
• The geometry of the airfoil is described with a variety of terms:
• The leading edge is the point at the front of the airfoil that has
maximum curvature (minimum radius).[7]
• The trailing edge is defined similarly as the point of maximum
curvature at the rear of the airfoil.
19. CFD RESULTS
• Velocity contours and pressure
distributions were obtained.
• Lift and drag forces measured across
multiple airfoil designs and angles of
attack.
20. COMPARATIVE ANALYSIS
• NACA 4412: Good lift characteristics
• NACA 0012/0018: Symmetrical, lower lift
• Horten Brothers: Thick profile, stable at
high AoA
21. CONCLUSION
• CFD and 3D printing enabled effective
airfoil design analysis.
• Key insights into aerodynamic
performance obtained for different airfoil
shapes.
