A NACA duct, [1] also sometimes called a NACA scoop or NACA inlet, is a common form of low-drag air inlet design, originally developed by the U.S. National Advisory Committee for Aeronautics (NACA), the precursor to NASA, in 1945.

Jul 18, 2013 · For today’s racers—and many generations of Italian sports cars—the qualities of the NACA duct that made it unfit for jets make it ideal for most other kinds of engines, and its low profile,...

May 23, 2024 · A NACA duct is a type of low-drag air intake vent used on a wide array of vehicles from space craft to airplanes, boats and automobiles. The intake vents were originally designed for jet engine use by the precursor agency to NASA, the U.S. National Advisory Committee for …

Nov 8, 2024 · In modern aircraft, the duct is used to vent or feed secondary systems. NACA ducts have been a mainstay of high-performance road cars too. They graced the hood of certain Lotus Elites in the...

Dec 21, 2012 · NACA ducts are submerged ducts – they are installed flat. The picture at left is a closeup of a carbon fiber NACA duct. The air comes into the narrow end and a hose is attached to the round part so that you can direct the air to the brakes or the driver’s airbox.

Jul 3, 2019 · As such, even in aircraft that first employed the NACA ducts, they were limited to ventilation purposes or cooling instead of supplying air necessary for engine combustion. This, in many ways, has made NACA ducts ideal for race cars or production sports cars that require brake cooling, water cooling, and passenger cooling.

Oct 22, 2024 · What is a NACA duct? A NACA duct is an aerodynamic design feature that improves airflow management in vehicles. It typically has a rounded entrance and tapered exit, helping to minimize drag while optimizing cooling for components like the engine and brakes.

NACA air inlet ducts (also known as NASA ducts) are the most efficient, lowest-drag way to direct cooling air. These ducts are molded from tough, high-impact black or clear plastic.

High quality vacuum formed Naca vent for low-drag, optimal interior cooling. Can be fitted in windows or bodywork as an air inlet. Available in Carbon Effect, Black and Clear colour options, and Mini, Small, and Large sizes.

Mar 29, 2012 · Placement of a simple, triangular baffle prevents the air from spilling out of the NACA scoop. An added and important benefit is that cylinder head temperatures are lowered by about 30 degrees for each cylinder.
