Dragster Aerodynamic Development Project

This project focused on aerodynamic development for a drag racing vehicle built for a Lithuanian racing team. Drag racing is a motorsport discipline where two vehicles compete in a straight-line acceleration race, typically over a quarter-mile distance. In this type of racing, every fraction of a second matters, meaning aerodynamic efficiency, stability, and airflow management become extremely important, especially at very high speeds.

Our work concentrated on improving the vehicle’s aerodynamic performance through several custom modifications and CFD airflow analysis. One of the primary upgrades involved redesigning the floor section by integrating vortex generators. These elements were introduced to better control airflow underneath the vehicle, helping reduce turbulence and improve overall airflow stability at high speeds.

Another major improvement focused on the hood design. The original configuration included additional air inlets which disrupted airflow and created unnecessary aerodynamic drag. To optimize efficiency, the hood was redesigned into a significantly smoother shape without extra inlet openings. This allowed airflow to remain more attached to the body surface, reducing separation and improving the vehicle’s overall aerodynamic behavior.

The project demonstrated how even relatively small aerodynamic modifications can positively influence drag reduction, airflow stability, and high-speed performance in professional drag racing applications.
