Aerodynamics

Drag (Air Resistance) The force acting opposite to the relative motion of any object moving with respect to a surrounding fluid (in this case air). Drag Coefficient The measure of drag of an object. Drag Profile The sum of the surface friction drag and the form drag for a body moving subsonically through a fluid Friction The resisting force of surfaces to a moving object Lift The component force of fluid passing through an object that is perpendicular to the oncoming flow direction.

Aerodynamics

Weight

The force on an object due to gravity.

Grip Force

The term describing the total cornering envelope of a race car by the friction component of the tire

Downforce

The downwards thrust created by the aerodynamic characteristics of a car.

Traction

The force used to generate motion between a body and a tangential surface

SLIDE 4

Bernoulli Effect

The increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.

Mechanical Terms

Kammback

A Kammback is a car body style that derives from the research of the German aerodynamicist

Wunibald Kamm in the 1930s. A car body style that includes a smooth top back that ends at the tail. This body style reduces drag Car Exterior

Exterior detailing involves cleaning and restoring or exceeding the original condition of the surface of

the car's finish, chrome trim, windows, wheels, and tires, as well as other visible components on the exterior of a vehicle. Defines how aerodynamic a car is. How fast it goes. Rear Spoiler Fin

A spoiler is an automotive aerodynamic device whose intended design function is to 'spoil'

unfavorable air movement across a body of a vehicle in motion, usually described as turbulence or drag. Wing

A wing is a type of fin that produces lift, while moving through air or some other fluid.

Drag Coefficient

Drag Coefficient = 0.36
Lots of pressure

Project Development Reflection

Molding the car to your desire after 3d printing it was hard
Doesn’t perfectly come out as expected
Designing the car was also hard
Design the car out of scratch instead of using the autodesk fusion as a

template

Autodesk Fusion and fusion flow to design and make adjustments to my car

accordingly to aerodynamics

Technical drawing skills improved
Learned

○ Sanding (which specific sanding tool to use)

Personal Reflection

With mutliple project deadlines, work management improved
This class helped me be a better learner through self learning of tutorials
Designing the car has made me a better thinker
Being able to use multiple forms a media on this presentation will help me

improve with communication

This class has shown and given me the option to contribute to the world

through engineering.
