Aerodynamics, branch of physics that deals with the motion of air and other gaseous fluids and with the forces acting on bodies passing through such a fluid. Information and a spreadsheet calculator are provided here (for educational purposes). See our posts below for free test data, and learn how we use wind tunnels, indoor velodromes and outdoors to improve and explore aerodynamic drag. With its fancy wind tunnel, Specialized is equipped to answer the big questions of bike and rider aerodynamics – and one of those is the drag coefficient of a beard. As an example, a 10w aerodynamic drag saving at 45kph is equivalent to 4.7w at 35kph. We tested the aerodynamics of the tyres at our typical test speed of 45kph. Start out with a couple easy ones and then try something more challenging. Car manufacturers are looking for a solution to execute more tests per day and get more results and data from every single test run. Factoring in both aerodynamics and rolling resistance, Ballard believes the GP4000 is still the best performer as a front tyre. For the rest of us, pin your ears back, get a note pad and pen and read on. This is the main reasons why after a brief introduction about which are the most important aerodynamic forces acting on a race car, we will focus firstly on the effect of said forces on performance and handling. Find helpful customer reviews and review ratings for DIY Testing of Car Modifications: How to test aerodynamics, flow test intake & exhaust systems, assess performance improvements, and measure actual ... all without spending more than $50. To better … High school students should be able to make sense of the math and science principles. The idea is to present motorcycling technology in a simple form everyone can understand, even children. The researchers do not specify a value of c w A, but instead instead give only the aerodynamic drag force (in lbf or "grams"). Table of Contents. It can only be effectively investigated in dedicated facilities. Aerodynamics; When the margin of victory is measured in thousandths of a second, every inch, every gram, every angle matters.

This allows us to get good clean data (compared with testing at lower speeds, where the resolution isn't as good) which can then be applied to lower speed calculations later. With advances in CFD, MDO, Wind-Tunnel and Flight-Test capabilities, the focus is also on what is needed to cope with future unconventional platforms. However, the tools still rely on the experience and intuition of the engineer, who must know, working from a baseline design, which parameters to change in order to create the permutations to be tested. Railway applications. This means that the team has to use each test run wisely, using the data collected to its advantage to make the most of the time in the wind tunnel. In the effort to move an object through air in the most efficient manner possible, Trek engineers dream, draw, build, test, and repeat. Aerodynamics of race cars by BBC News, 25 February 2004.
