Wind machine (film)

The wind machine is usually at shooting applied to air - to simulate and severe weather effects.

In the early days, gasoline-powered aircraft engines and rotors from Curtiss-Wright were used for this purpose, but these had the massive disadvantage of not only generating enormous noise, but also producing annoying exhaust gases . Today only moving electric giant fans are in use. Although the noise level has been minimized by using electric motors , the unavoidable wind noise is usually reduced by diverting the air flow through canvas ducts .

Types of wind machines

Directional wind blower

• Small wind machines: Propellers only generate weakly directed wind power
• Tube wind machine: Strongly directed wind current with a wind exit diameter of 840 mm.
• Flow fan: Extremely strong wind

Surface wind blower

• Ring fan: Generation of medium-weak, area-wide airflow.
• Propeller wind machine: Strong but extensive wind
