Turbine-rotor-blade designs based on one-dimensional-flow theory 1: performance of single-stage turbine having 40-percent reaction
Report presenting an investigation of a family of turbine-rotor-blade designs based on one-dimensional-flow theory and incorporating systematic changes in design variables. They were designed for 40-percent reaction and a total-to-static pressure ratio of 4.00 based on the assumption of constant static pressure along the radius and one-dimensional-flow theory for the design of the rotor-blade passages.

Free-Spinning-Tunnel Tests of a 1/24-Scale Model of the Grumman XF9F-2 Airplane with Wing-Tip Tanks Installed
"An investigation of the spin and recovery characteristics of a 1/24-scale model of the Grumman XF9F-2 airplane with wing-tip tanks installed has been conducted-in the Langley 20-foot free-spinning tunnel. The effects of control settings and movements on the erect spin and recovery characteristics of the model for a range of possible loadings of the tip tanks were determined. Spin and recovery characteristics without tanks were determined in a previous investigation" (p. 1).
