Last year we wrote an article about aerodynamic analysis using CFD of a Dirt Late Model that garnered a lot of attention. On that model one of the most prominent aerodynamic devices is the rear spoiler. One question that often comes up is, what is the difference between a spoiler and a wing? Some people … Continued
The GoFly Prize is a Boeing-sponsored competition in which more than 3,500 innovators on 824 teams from 103 countries create a personal flying device such as a UAV to compete for $2,000,000 in prizes. In 2018, TotalSim was asked by the GoFly Prize organizers to provide contestants with CFD simulation software allowing the top minds … Continued
We are proud to announce that TotalSim US have been awarded a Small Business Innovation Research (SBIR) Phase I project through AFWERX and AFRL with the Department of Defense. The SBIR program is a highly competitive program that encourages domestic small businesses to engage in Federal Research/Research and Development (R/R&D) that has the potential for … Continued
It’s the most wonderful time of the year: Christmas. Every year, kids (and some adults) eagerly wait for Santa to deliver their presents. As you watch the Santa Trackers, you’re probably wondering if Dasher or Rudolph could fly a little quicker so that the presents get delivered sooner.
This version of Santa’s sleigh, named the Jingle Jet, is designed and drawn by Mikael Sedlacek. It’s equipped with 2 jet turbo engines; therefore, this sleigh does not require the services of Santa’s 10 reindeer. The Jingle Jet is designed with an aerodynamic body so that it can glide through the sky.
Dirt track racing is a popular form of automotive racing in the United States. Dirt Late Model is a unique vehicle, with its inclined nose, flat doors, large spoiler, and open backs. Typical weight of a Dirt Late Model is a minimum of 2,300 lbs. These vehicles require a powerful engine that can produce over 800 horsepower that allows the vehicle to achieve high speeds. From the tight wheel arches to the angle and location of the rear spoiler to the different fender heights, every design component of this vehicle influences aerodynamics. Wind tunnel testing for this type of vehicle is difficult due to the extreme yaw (side slip angle) the cars experience while cornering. Without the constraints of the wind tunnel, Computational Fluid Dynamics (CFD) methods are ideal for testing and understanding the aerodynamics of dirt racing cars.
