註釋The results of flight measurements of the performance and cooling characteristics of the XP-42 airplane equipped with a short-nose low-inlet-velocity cowling are given. The tests include measurements in high-speed level flight and in climb of the effects of: (1) a spinner-mounted axial-flow fan without propeller cuffs; (2) no fan or cuffs; and (3) two different sets of propeller cuffs. This cowling is one of a series being tested in an effort to improve the characteristics of radial air-cooled engine installations.
