Aerodynamics & Car Design Flashcards
What is Aerodynamics in car design?
Aerodynamics refers to how air flows around and through a car. Good aerodynamics reduce drag, improve efficiency, increase speed, and enhance stability.
What is Drag?
Drag is the air resistance a car faces while moving. Lower drag helps a car move faster and more efficiently, improving fuel economy.
What is the purpose of a Spoiler?
A spoiler is an aerodynamic component designed to disrupt airflow, reducing lift and increasing downforce to keep the car stable.
What is Drag Coefficient (Cd)?
The drag coefficient (Cd) is a number that represents how aerodynamic a car is. The lower the Cd, the less air resistance the car encounters.
What is Downforce?
Downforce is the aerodynamic force that pushes a car towards the ground, improving traction and handling, especially at high speeds.
What is Lift in car aerodynamics?
Lift is an upward force caused by air passing over the car, which can reduce traction. Aerodynamic design aims to minimize lift for better stability.
What is a Diffuser?
A diffuser is located at the rear of a car, accelerating airflow under the vehicle to create a low-pressure area, increasing downforce.
What is the function of an Air Dam?
An air dam is a barrier placed at the front of the car to reduce the amount of air going under the vehicle, reducing lift and drag.
What are Venturi Tunnels?
Venturi tunnels are channels underneath the car that create a vacuum effect, significantly increasing downforce by accelerating air flow.
What is the role of Vortex Generators?
Vortex generators are small aerodynamic devices that control airflow over the car, reducing turbulence and drag at high speeds.
How do Aerodynamic Mirrors help in car design?
Aerodynamic mirrors have streamlined shapes that minimize drag and turbulence, contributing to overall efficiency.
What is the Kammback Design?
A Kammback is a design where the rear end of a car is abruptly cut off, reducing drag by allowing air to flow more smoothly, seen in many hatchbacks and sport cars.
What is a Hood Scoop?
A hood scoop directs air into the engine bay, either for cooling purposes or to force more air into the engine for improved performance.
What is Active Aerodynamics?
Active aerodynamics refers to components like spoilers or vents that adjust based on driving conditions to optimize airflow, reduce drag, or increase downforce.
How does Streamlining affect car design?
Streamlining involves shaping a car to reduce air resistance. Sleek, smooth curves and avoiding sharp edges help reduce drag and increase efficiency.
