An analytical investigation of airplane spin-recovery motion by use of rotary-balance aerodynamic data

From Introduction: "Many investigations have been made in the Langley 20-foot free-spinning tunnel in which the natures of airplane spins and recoveries have been determined experimentally with dynamically scaled-down models. The results of some of these investigations are presented in references 1 to 5."

An Analysis of the Variation With Altitude of Effective Gust Velocity in Convective-Type Clouds (open access)

An Analysis of the Variation With Altitude of Effective Gust Velocity in Convective-Type Clouds

From Introduction: "In the present paper, the variation of effective gust velocity in convective-type clouds with altitude is investigated. Data obtained during 1941 and 1942 at altitudes up to 34,000 feet and data obtained more recently from the Thunderstorm Project (reference 5) at altitudes up to 26,000 feet are utilized for this purpose. Consideration is given in analyzing the results both to data for the range
