Summary

Description This test fuselage (circa 1926) is fitted with Cowl No. 10, the prototype for the first commercial installations. Developed in the PRT to reduce air resistance around a radial engine, the NACA Cowl proved to both lower air resistance and improve engine cooling. It earned the NACA its first Collier Trophy in 1929 and rapidly became a standard appliance for radial engines.
