Lightweight hand laid fiberglass NACA ducts (National
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.
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.
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.
