Drag and Cooling With Various Forms of Cowling for a Whirlwind Engine in a Cabin Fuselage
An investigation on the cowling of radial air-cooled engines was conducted in the 20-foot Propeller Research Tunnel at Langley Field. Cooling and drag tests were made with each form of cowling. The propulsive efficiency was found to be practically the same with all forms of cowling.

The Variation in Pressures in the Cockpit Fan Airplane in Flight
"The results of an investigation to determine the pressures in the open cockpit of a Vought VE-7 airplane are given. The information has been considered valuable on account of its possible effect upon the operation of instruments, particularly altimeters, due to a variation from the true static pressure which is induced by the passage of the airplane through the air. The observed values are small and the effect upon instruments is inconsiderable" (p. 1).
