the.com/wind tunnel
A tube that lies about moving so things can tell the truth about flying.
means A chamber that blows controlled streams of air over a stationary model or vehicle so engineers can measure lift, drag, and airflow without anything actually going anywhere.
from A straightforward compound of 'wind' and 'tunnel,' coined in the late 1800s as inventors like Francis Wenham built the first enclosed boxes to blast air over wing shapes — flight experiments that predate the Wright brothers and let researchers study aerodynamics on the ground instead of guessing in the sky.
- origin
- Wright brothers built one in 1901, tiny box
- trick
- model stays still, air does the running
- scale
- NASA's largest fits a full-size plane
- beyond flight
- also tests cyclists, buildings, and golf balls
