# What is an aerodynamic analysis?

3.1 Aerodynamic analysis

The main reason of the aerodynamic analysis is to determine drag coefficient of the vehicle which affects fuel consumption, predict low and high pressure areas, separation points and down force which affects vehicle dynamics. All these parameters are also investigated deeply in this project.
• ### At what speed does drag matter?

At speeds over 9 mph, it's the dominant force of resistance. By the time you hit about 30 mph, 90 percent of your power goes into overcoming air resistance, or what scientists call aerodynamic drag.19 oct 2021
• ### What's the most aerodynamic shape?

For speeds lower than the speed of sound, the most aerodynamically efficient shape is the teardrop. The teardrop has a rounded nose that tapers as it moves backward, forming a narrow, yet rounded tail, which gradually brings the air around the object back together instead of creating eddy currents.
• ### Does more drag mean more fuel consumption?

This means that at freeway speeds the frictional drag is no longer the main gas guzzler – aerodynamic drag will now account for more half of the fuel you're using, or even more. The faster you go, the more fuel you use pushing your car through the air.
• ### How much downforce does an F1 car produce?

Modern Formula One cars can generate as much as 5G down force. That means, at full speed, the effective weight pressing down on the track will be 5 times the weight of the car. Almost all the surfaces of a Formula One car are engineered to produce down force.13 abr 2021
• ### How is drag calculated?

The drag equation states that drag D is equal to the drag coefficient Cd times the density r times half of the velocity V squared times the reference area A. D = Cd * A * .5 * r * V^2. For given air conditions, shape, and inclination of the object, we must determine a value for Cd to determine drag.
