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
to determine drag on whatever object you place in the tunnel. the tunnel simulates the wind with a big fan at one end, and the subtle changes in drag are measured in terms of air resistance in different position. The purpose is usually to make something go faster (be more aerodynamic and have less 'drag' (downforce) ) such as F1 cars and cyclists in Time Trial events
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.
Malcolm Sayer (For Jaguar) - He was an aircraft designer who moved to Jaguar and designed the iconic E type Jaguar. This was the first vehicle to be tested in a wind tunnel. With respect to the previous contributor, development of another "iconic" automobile, the SAAB 92, was underway more than a decade before Jaguar began development of the E-type. The SAAB 92, developed by aircraft engineers & designers, was one of the first (if not the first) moderately-priced, volume-produced car whose shape was perfected through wind tunnel testing. Its coefficient of drag in the low 0.30s backs up that claim.
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.
Unitary Plan Wind Tunnel was created in 1955.

The answer is Wind + Water

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.
