3" NACA Duct - Carbon Fiber
NACA Duct - 3" 100% Carbon Fiber
These light weight carbon NACA ducts are perfect for venting driver cooling systems, helmet air kits and brake kits. Anytime fresh air needs to be brought into the cockpit or ducted to vital components, these 100% carbon fiber ducts are the perfect solution.
Ultra light weight and wind tunnel tested. Our NACA ducts bring air into a vehicle with minimal increase in drag. The purpose of a NACA duct is to increase the flow rate of air through it while not disturbing the boundary layer. When the cross-sectional flow area of the duct is increased, you decrease the static pressure and make the duct into a vacuum cleaner, but without the drag effects of a plain scoop. The reason why the duct is narrow, then suddenly widens in a graceful arc is to increase the cross-sectional area slowly so that airflow doesn’t separate and cause turbulence and drag.
