As modern high-speed trains reach velocities of 250–350 km/h, the greatest engineering challenge is no longer engine power — it is the interaction with air.
In rail systems, aerodynamics plays a critical role not only in speed, but also in safety, energy efficiency, and passenger comfort.
At this point, the advanced engineering solutions offered by Fetech İleri Mühendislik help elevate the performance of train and metro systems to the highest level.
At high speeds, the majority of resistance acting on a train is aerodynamic.
This makes one thing essential:
👉 Designing the most aerodynamically efficient shape
These analyses are performed using advanced simulation tools such as ANSYS Fluent.
The elongated and streamlined nose of high-speed trains is not just a design choice — it is an engineering necessity.
A well-known example is the Shinkansen trains, famous for their optimized nose geometry.
When a high-speed train enters a tunnel:
This effect:
Through CFD simulations, Fetech:
High-speed trains are exposed to crosswinds, especially in open terrains.
Key parameters analyzed:
At high speeds, noise is no longer mainly mechanical — it becomes aerodynamic.
Main noise sources:
With CFD-based aeroacoustic analysis:
Sudden pressure variations can cause:
Therefore:
are carefully analyzed and optimized.
With aerodynamic improvements:
This is especially critical for:
