Wind Tunnels

Wind tunnels let engineers test how air moves around cars, airplanes, and other shapes.

How It Works

A wind tunnel blows controlled air around a model or full-size vehicle. Smoke, sensors, and cameras can show how air flows.

Why It Matters

Car designers use wind tunnels to reduce drag and wind noise. Airplane designers also use wind tunnels to test lift and stability.

Did You Know?

Engineers study wind tunnels by testing, measuring, improving designs, and learning from real-world use.
