I read many introductions of vertical wind tunnels on the Internet. I wonder how much power is consumed in the vertical wind tunnel. Has anyone calculated the power consumption?

Power consumption is very high. The larger the diameter of the flight area of the wind tunnel, the greater the power consumption. There is a small outdoor wind tunnel in Kunshan, Jiangsu. It is said that the power consumption is 360KW. The company seems to be called Yang Shenghao Precision Machinery. You can check it online, and there should be a specific introduction. Generally speaking, transformer application takes a long time, complicated procedures and high costs. It is better to use diesel generator sets, which are their own fixed assets at any time.
