AERODYNAMICS
# INTRODUCTION
# OBJECTIVES
# DRAG EXPLANATION
# TYPES OF DRAG
# F1 TECH
 Aerodynamics is the way air move around things.
 Study of the properties of moving air and the interaction
between the air and solid bodies moving through it.
AUTOMOTIVE AERODYNAMICS
 Study of aerodynamics of cars and racing vehicles.
AERODYNAMICS
OBJECTIVES
• Reducing Drag
• Influencing the way that how a car cuts through air
• Reducing wind noise
• To provide vents for engine cooling ,etc..
• Preventing undesired lift forces at high speeds.
• For providing better downforce for good traction.
DRAG
• Also called as air resistance
• It depends on velocity
• Advantages when reducing drag
1. Better fuel economy
2. Good performance
Types of drag
• Pressure drag
• Friction drag
Example of pressure drag by sphere
HOW IT HAPPENS?
FRICTIONAL DRAG FOR VARIOUS
SHAPES
DRAG CALCULATIONS
• Formula
FORMULA-1 TECHNOLOGY
RESULTS OBTAINED AND USES
Best optimized designs for manufacturing
1. FRONT WINGS
2. REAR WINGS
3. DIFFUSERS ETC..
 Benefits
1. Reduced lift forces
2. Increased traction by increasing down force
FRONT WINGS
REAR WINGS
F1 REAR WINGS DRAG RACE CARS WINGS
DIFFUSERS
CFD ANALYSIS OF F1
