Type of Wind Tunnel


■The Maibara Wind Tunnel has two test sections that can be selected according to the test purpose.
Both test sections are equipped with instruments to efficiently implement wind tunnel tests. See the following for details.

Open test section

Open test section
@RTRI
　The open test section is used to test mainly the aerodynamic noise generated from the test model placed on a supporting gear between the nozzle and the collector.The cross section of the open test section is 3m wide x 2.5m high.

Closed test section

Closed test section
@RTRI
　The closed test section, 5m width x 3m heightx 20m length, is composed of a windward wind tunnel (length 6.5m) and a leeward wind tunnel (length 13.5m), both separately movable, and used to test and improve the characteristics of the aerodynamic force and drag work on train models and study the flow around them.
