The NACA Cowling is a type of Aerodynamic Fairing used to Streamline Radial Engine s for use on Airplane s. Developed by the National Advisory Committee For Aeronautics in 1927 , it was a major advancement in Drag reduction, and paid for its development and installation costs many times over due to the gains in Fuel Economy that it enabled. The test aircraft, a Curtis Hawk AT-5A biplane, featuring with a Wright Whirlwind J-5 radial engine, reached an airspeed of 220km/h equipped with the NACA cowling compared to 190km/h without it. The NACA cowling causes cool air blown onto the center of the motor, which is routed across the motor's hottest parts, i.e. the Cylinder and even more important, the Cylinder Head . Furthermore, turbulences after the air passes the free-standing cylinders, are prevented. The sum of all these effects reduces drag by 60%. The test conclusions resulted in almost every aircraft equipped with this cowling, starting in 1932 . SEE ALSO EXTERNAL LINKS
