Article C3.15.5
Internal Cooling Ducts
Chapter: C3
In Simple Terms
Teams can use special internal cooling ducts to cool their cars, but these ducts must stay within a defined drum-shaped area and air flowing through them must pass through a specific plane (called YW = -50). There's also a limit to how much air can flow into this cooling drum to prevent teams from gaining unfair advantages.
- Internal cooling ducts have a specific exemption but must be contained within the 'Scooped Drum' structure
- All cooling air flow must pass through the YW = -50 plane as it travels from inlet to outlet
- Teams cannot exceed specified flow rate limits for air entering the cooling drum
- These rules prevent teams from using cooling systems as a loophole to improve aerodynamics
Official FIA Text
Internal Cooling Ducts exempt from C3.2.4 must lie within Scooped Drum. Flow from Scoop Inlet to Outlet must pass through YW = -50 plane. Flow entering Scooped Drum must not exceed specified flux limits.
