The low speed wind tunnel data acquiring and the closed loop controlling of wind velocity are realized by PLC and human machine interface and inverter from Fuji.

采用富士plc、人机界面与变频器实现了低速风洞数据采集和风速的闭环控制。

This loop also passes through the Sasso San Gottardo, a demilitarised tunnel that is part of a network of clandestine Swiss Army caves and tunnels built into the mountain and used as bunkers during WWII and the Cold War.

The tunnel will also create a 13-mile (21km) loop between Bath and Midford via the canal towpath in the city.
