Pro-Werks C42-030 NACA DUCT 7 in. Hand Laid Fiberglass 14 in. Long 7 in. Wide 2 in. Inlet Depth Made in the USA Lightweight hand laid fiberglass NACA ducts (National Advisory Committee for Aeronautics) provide a positive low resistance method of air transfer. Depending on which direction that they are mounted, they will either introduce fresh air where needed, or remove it. Similar to an airplane, drag is undesirable for a race car. Every bit of drag on an airplane, a rocket or a race car increases the amount of fuel consumed and limits the maximum speed. Launching spacecraft is expensive, which makes minimizing drag critical. A NACA duct transfers air where needed in or out of a vehicle with minimal increase in drag. They are easily attached with bonding compound or riveted on fiberglass, aluminum, or steel body panels. Multiple ducts maybe mounted side by side when increased airflow volume is required. The mounting flange width measures approximately 1". NACA (the National Advisory Committee for Aeronautics) was the predecessor of NASA (the National Aeronautics and Space Administration). |
