When it comes to racing, aerodynamics is everything. A well-designed aero package can make the difference between winning and losing, and at Revolve NTNU, we take this very seriously. From the initial concept to the final carbon fiber part, the journey is long, detailed, and highly technical, and Ovun plays a crucial role in turning our designs into reality.
Our journey begins months before any part is produced. Using Computational Fluid Dynamics (CFD), we digitally simulate airflow over the car’s surfaces. This allows us to experiment with various shapes and designs to optimize downforce, reduce drag, and maximize efficiency. Each part, whether it's a front wing, rear wing, or side pod is tested virtually to make sure it will perform as intended on the track.
Once the design is finalized, we create a combined CAD model for both the mould and the core, ensuring every part fits seamlessly. These CAD designs are sent to Ovun, who has been a trusted partner for more than a decade. Ovun takes our designs and machines them into MDF and IGF moulds that form the backbone of our aerodynamic components.
Ovun’s skilled technicians use advanced CNC machining to mill out the precise geometries from the raw MDF and IGF materials. This process is incredibly important, as even the smallest deviation could affect the aerodynamic performance of our car. Their expertise in working with these materials ensures that the moulds are of the highest quality, capable of handling the composite manufacturing process with precision.
The moulds then go through a detailed sanding process, starting with P240/320 grit and finishing with P600 to achieve a smooth surface. After sanding, we apply Teknoseal, which consists of four thick layers to prevent adhesion and improve durability. This is followed by clear coating and additional sanding to perfect the finish before the moulds are ready for casting.
When the moulds are complete and prepped, the real magic begins. Layers of carbon fiber are hand-laid onto the moulds and then cured to create lightweight yet incredibly strong components. This process ensures that our aero parts are optimized for both weight and structural integrity.
For some components, a core material is added before casting. This strengthens the structure while keeping it lightweight. The finished part is then cured under precise conditions, solidifying the layers and bonding everything together seamlessly.
After curing, the parts are demoulded, trimmed to exact specifications, and thoroughly inspected for any imperfections. Only then are they mounted on the car for testing and validation. Every step is critical to ensure the part not only fits perfectly but also performs as expected on the track.
Ovun’s precision and commitment to quality have been instrumental in our aerodynamic development. For more than 10 years, they have delivered precision moulds and materials, consistently meeting our high standards and tight deadlines. Their support goes beyond just moulds, they are a true partner in innovation.
We are incredibly grateful for the continued partnership with Ovun and look forward to pushing the limits of aerodynamics together in the seasons to
