Testing of the Škoda 26Ev train operated by Arriva has begun in a wind tunnel. The wind tunnel tests are conducted to determine the train’s aerodynamic characteristics for certification purposes. Among other things, the tests assess the vehicle’s sensitivity to crosswinds under operational conditions. The aim is to determine whether the structure remains stable and resistant to overturning even in adverse conditions.
The model is placed in the airflow on a special rotating platform that simulates a railway embankment. Tests will be conducted at various yaw angles with airflow speeds of up to 75 m/s (270 km/h). A total of 30 different scenarios will be tested over several days. Before the actual testing, construction work on the model was required, and an extensive evaluation will follow.
The wind tunnel has a test section diameter is three meters and is the largest of its kind in Central Europe. It can generate wind speeds of up to 90 m/s (324 km/h). For comparison, a hurricane reaches Category 5 on the Saffir-Simpson scale, starting at 70 m/s. The wind tunnel’s total power consumption is 2.2 MW.
