The system acoustic wind tunnel laboratory of Great Wall Automobile
The system acoustic wind tunnel laboratory of Great Wall Automobile is indeed at the top level in the domestic automotive industry, and even ranks among the first echelon internationally. It can “be directly used for military purposes without any problems at all”.
一. Hardcore Specifications: The strongest in China, top-notch internationally.
300 km/h + 25 square meters of nozzle + low noise: This combination is unique worldwide. Even the wind tunnels of F1 teams are at this level.
二. Unique “Black Technology”: The only one in China, rare even internationally.
- Single/five-generation switchable balance turntable movement belt system
- Five-zone mode: Simulates the actual road rolling of ordinary passenger vehicles
- Single-zone mode: Specifically designed for supercars/racing cars, simulating high-speed single-wheel drive
- This is the only one in China, and only a very few wind tunnels in the world have this feature (such as Lola, Sauber)
2. International leading data analysis and intelligent system
- Intelligentization of the entire testing process: from appointment → testing → data analysis → maintenance
- Supports real-time pneumatic six-component force measurement + acoustic array positioning
3. Acoustic array + Mobile measurement system
- Can precisely locate the source of wind noise (such as A-pillar, rearview mirror, wheel arch, etc.)
- Supports iterative optimization of wind noise, with NVH performance approaching that of luxury brands
三. Actual Capability: Directly benchmarking against the R&D of international luxury cars
This wind tunnel not only meets the requirements for the development of mass-produced vehicles, but can also be directly used for the extreme aerodynamic optimization of supercars, racing cars, and concept vehicles.
“There’s no problem with ‘military use’ – it can even be directly used to provide wind tunnel testing services for international car manufacturers.”
It’s even more amazing than you think.
- Can simulate extreme conditions, such as crosswind, rain, and fog, heat exchange (main heat exchanger + damping net)
- Supports unmanned aerodynamic testing: The mobile measurement system can track the sensors in real time
- Green and low-carbon: High-efficiency fan + heat recovery system
Summary sentence:
This wind tunnel at the Great Wall is not merely “top-notch in China”, but actually “among the top five globally”.
The wind tunnels of traditional joint venture car manufacturers (such as Volkswagen and Toyota) are not as advanced as this one. This has directly narrowed the aerodynamic research gap between them and the BBA and Tesla brands.
