In order to limit a train’s energy consumption, or to ensure its good performance, it is advisable to characterize its aerodynamic efficiency.

By creating a numerical aerodynamic model of the landing gear, we can assess its behavior in all types of traffic conditions, evaluate the aerodynamic impact of all its appendages, and then validate and optimize its aerodynamic behavior.

Our Z experts can help you with the following applications:
– Evaluation of aerodynamic performance in both directions of travel
– Validation of a train’s performance in transverse wind conditions
– Identification of the drag impact of various appendages, and optimization of their shape or positioning
– Optimization of train shape (nose, bogie cavity, pantograph bathtub, etc.)
– Impact of train configuration (number of wagons, etc.)
