Race Car Aerodynamics Gregor Seljak April 8‚ 2008 1 Introduction First racing cars were primarily designed to achieve high top speeds and the main goal was to minimize the air drag. But at high speeds‚ cars developed lift forces‚ which affected their stability. In order to improve their stability and handling‚ engineers mounted inverted wings profiles1 generating negative lift. First such cars were Opel’s rocket powered RAK1 and RAK2 in 1928. However‚ in Formula‚ wings were not used

Advantages of Aerodynamics for Modern Performance Cars Advantages of Aerodynamics for Modern Performance Cars Thesis: Aerodynamics‚ the effects of air flow over surfaces‚ is an indispensable element for modern cars’ efficiencies‚ both economics and performance related‚ because aerodynamics helps to decrease the dragforce‚ makes cars more stabilized and gives a chance of reducing fuel consumption. I. Performance A. Aerodynamics Basics 1. Theory a. Air flow b. Pressure and forces

INTRODUCTION TO AERONAUTICS: A DESIGN PERSPECTIVE CHAPTER 3: AERODYNAMICS AND AIRFOILS “Isn’t it astonishing that all these secrets have been preserved for so many years just so that we could discover them!!” Orville Wright 3.1 DESIGN MOTIVATION The Physics of Aerodynamic Forces Figure 3.1 shows a cross section view of an aircraft wing. A wing cross section like this is called an airfoil. Lines drawn above and below the airfoil indicate how the air flows around it. The

damping ratios instead of actual damping coefficients is so that we can normalize the discussion for all dampers. Choosing a damping ratio is a generally a tradeoff between response time and overshoot (you want to minimize both). Typically‚ passenger cars will use a damping ratio of around 0.25 to maximize ride comfort. For a racecar‚ the damping must be considerably higher for road holding and control of the unsprung mass motion. Data has shown that for racecars‚ a good baseline for damping ratio is

Homework Introduction to Aerodynamics Name: Natalie Hume 1. In your opinion what has been the most important development/invention in the history of aerodynamics and why? I feel that I could pick something very complex and technical for this question. But I think in terms of science and simplicity I pick Bernoulli’s principle. This principle laid the foundation for the development of aerodynamics. It allowed for people to understand the relationship between pressure and velocity and continue

Aerodynamics General aerodynamics Paper aircraft are a class of model plane‚ and so do not experience aerodynamic forces differently from other types of flying model. However‚ their construction material produces a number of dissimilar effects on flight performance in comparison with aircraft built from different materials. In general‚ there are four aerodynamic forces that act on the paper aircraft while it is in flight: • Thrust‚ which keeps the plane moving forward; • Aerodynamic lift

“During each NASCAR race they average 8 crashes every race”(Wikipedia‚ 2016). Some people believe that race car drivers are not athletes. People who side with NASCAR is a sport say that there is a lot of what the drivers do besides just get into the car and drive. People who don’t believe it’s a sport say that anyone can get into a car‚ turn left and anyone can do it.There are many good points to both sides‚ most people believe race car driving is a sport‚ but some who say it is not. There are many

Derp‚ the GT Turbo Starlet race car went from 60 then gradually up to 100 then to 150 till it hit the 180 mark. With both feet on the pedal‚ one hand on the wheel and the other on the gear‚ Dale glanced at me sitting on the passenger seat. Right then and there‚ my heart went from normal to a heart beating itself out of my own body because of fear. Or was it adrenaline? Or excitement? I didn’t really know. Everything was mixing with everything else as the race car got faster. It was somewhere in

Are Race Car Drivers Athletes? When people hear the word athlete‚ the first people they probably think of are athletes like Reggie Bush‚ Kevin Garnett‚ or Sidney Crosby. The last kind of person that is probably thought of is a race car driver. Which raises the question‚ is a race car driver a true athlete? Much of this depends on how you would define the word athlete. According to The Merriam Webster Dictionary‚ athlete is defined as “a person who is trained to compete in athletics” (Merriam-Webster)
