 Wind
tunnels have been around
for well over a hundred
years. Even before powered
flight had been achieved
aircraft designers like
the Wright brothers used
them to understand how
air flowed over aircraft
surfaces.
Wind tunnels come in
many different sizes and
can reach speeds from
1 mph to over 17, 000
mph. Most are used for
testing aircraft but can
also be used for testing
cars, submarines, buildings,
golf balls, and even wheelchairs.
Wind Tunnels are fairly
simple devices, but have
you ever wondered how
a wind tunnel works? Johnny
Alonso spoke with NASA
Langley Researcher Luther
Jenkins to find out more.
