Large-scale low-noise wind tunnel
TESTING AND TRIALLING FACILITIES
RTRI Japan
RTS PRIORITY AREAS1
Capability Statement
This wind tunnel provides the world high performance of low noise (75.6 dB at 300 km/h) and wind speed (max. 400 km/h). It serves the purpose of basic research and development of technologies aimed at aerodynamic noise reduction in high-speed operation, reduction of train air resistance and improvement of aerodynamic noise characteristics, etc.
Capability – Systems
Carbody; pantograph
Capability – Testing
Aerodynamic noise tests (open tunnel); aerodynamic drag tests (closed section)
