wind tunnel
Aerodynamics testing facility
A wind tunnel is a chamber where air is blown past a stationary object to study aerodynamic effects—essentially simulating flight or motion while the object stays still.
Engineers use wind tunnels to test aircraft designs, car bodies, and building models: The prototype spent months in the wind tunnel before production.
Scale models and full-size vehicles alike undergo wind tunnel testing to measure drag, lift, and airflow patterns.
