DOME has been working on wind tunnel experiments enthusiastically since the early days, when we delivered the super sports car DOME-ZERO. We constructed the 25% wind tunnel with moving belt in 1987, the 50% one in 2001. We have been striving for aerodynamics.

DOME TUNNEL■Facility Construction

Steel-framed steel plate structure (plate thickness:9mm). A horizontal closed-return Gettingen type wind tunnel has been installed indoors, whose air duct length is 99m. Wind temperature can be steadily regulated to optimize the laboratory environment. Sound insulation is provided to preserve the surrounding environment.

DOME TUNNEL ■Test Section

The test section is 2.75m wide by 2.5 m high, which is sufficient for testing 50% F1 models and other similar vehicles. The test section is 8 m long and is sufficient for tandem testing involving turbulence simulation.


The main fan is an axial-flow type and operates stably to produce winds up to 60m/s.

DOME TUNNEL■Contraction Cone

A high contraction ratio of 8.3 ensures stable airflow and uniform temperature distribution.

DOME TUNNEL■Cooling System

The facility includes a cooling system capable of wind temperature control within a range of 25±3℃ (at a wind speed of 45 m/2), which is sufficient for consistent measurement.


A moving belt 2m wide and 5.5 m long (equipped with a vacuum system) is installed on the floor of the test section. This belt runs at up to a maximum wind speed of 60m/s, the fastest belt speed achieved in Japan. A boundary-layer suction unit is installed at the front end of the belt. The moving belt is installed on a turntable for testing involving a yaw within ±5 degrees. There are also tire arms to suit this type of experiment.
