A novel leeward airbag for enhancing aerodynamic characteristics of a high-speed train in crosswind: The effect of installation positions

Key Points

• The leeward airbag significantly enhances the aerodynamic characteristics of a high-speed train in crosswind conditions,
• An increase of 25% in stability was observed during testing at speeds over 200 km/h,
• Assessment involved varying installation positions of the airbag to determine optimal placement,
• Implications support the development of better safety features for high-speed trains in windy conditions.
