AI-assisted Moveable Aerodynamic Flaps
What is the product?
AI-assisted moveable aerodynamic flaps that automatically adapt to changing driving conditions in real-time. These intelligent devices are designed to reduce drag on heavy goods vehicles (HGVs) by optimising airflow around the truck’s trailer.
What is it used for?
The flaps are mounted at the rear of trailers and actively change position based on wind conditions, vehicle speed, and crosswinds to minimise turbulence. The system uses machine learning algorithms and onboard sensors to determine the optimal flap position on the fly—without any input from the driver.
Why is it of benefit to industry?
Aerodynamic drag is one of the biggest contributors to fuel consumption in road freight accounting for 50-70%. These adaptive flaps have demonstrated drag reductions of up to 10% till now. The benefits aren’t just economic by reducing fuel consumption: reducing drag means lower CO₂ emissions, helping fleet owners meet ESG goals and upcoming sustainability regulations. For the case of electric vehicles, it increases their range.
What has it been proven to achieve?
Proven in wind tunnel trials at NWTF at Imperial (scaled vehicle 1:14), the AI-flap system showed reliable response to side-wind conditions, maintaining aerodynamic efficiency across a wide range of driving scenarios, without the need for manual setup or compromise on drivability. Since the technology is based on AI, it can adapt to any type vehicle and improve its performance as more data become available. This allows it to adapt as well to specific driving and environmental conditions, as well as geometries for flaps and trucks.
How can industry test this product or get involved?
We’re actively seeking industrial collaborators to pilot the technology in real-world settings. Whether you’re a fleet operator, trailer manufacturer, or Tier 1 supplier, we offer:
- AI algorithms and hardware implementation for the aerodynamic control system. Custom prototype development tailored to your vehicles.
- Support for grant-funded collaborative R&D projects
- Access to NWTF’s advanced wind tunnel facilities to evaluate your own designs
