it is a simulation of real running turbine or compressor blades, since it is difficult to study a rotating and mooving machin, its better to fix the blade and let the air circulate, then study all the parameters... bilal el samad mechanical engineer
Frank wenham invented the first wind tunnel in 1871 in Greenwich England with his colleague John Browning
Aerodynamics
the purpose is they can find the best shape to go with the wind
A subsonic wind tunnel is a wind tunnel that cannot take testing to Mach 1 (the speed of sound). There are a wide variety of wind tunnels, and they come in a broad range of sizes, too. They span models from ones that test motorcycle helmets to ones that test a whole small aircraft or aircraft model. A link is provided to the Wikipedia article on the wind tunnel, and you'll find that link below.
Without wind tunnel testing and other testing, testing in flight would be even more dangerous to the test pilot, and anyone killed should the aeroplane crash.
Cascade Tunnel was created in 1900.
The present Cascade Tunnel is 7.79 miles long. The original Cascade Tunnel was 2.63 miles long.
the answer is 14.5 miles
7.79 Miles
A wind tunnel.
"Baals wind tunnel" likely refers to a wind tunnel named after renowned aerodynamicist Ludwig Prandtl. Prandtl's work on wind tunnels in the early 20th century was foundational in understanding aerodynamics, and his name is often associated with wind tunnel research and design.
Unitary Plan Wind Tunnel was created in 1955.

Wind tunnels are different sizes.
It doesn't directly. A wind tunnel is used to detect the airflow over objects such as cars and planes to improve the streamlining.
