Types of drags 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 It also explains the current techniques used in formula1 racing

3. 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.

4. DRAG
• Also called as air resistance
• It depends on velocity
• Advantages when reducing drag
1. Better fuel economy
2. Good performance

5. Types of drag
• Pressure drag
• Friction drag

7. Example of pressure drag by sphere

8. HOW IT HAPPENS?

11. FRICTIONAL DRAG FOR VARIOUS
SHAPES

13. DRAG CALCULATIONS
• Formula

14. FORMULA-1 TECHNOLOGY

15. 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
