When George Washington\u27s Ghost Turned Handsprings: South African Conflict and American Identity, 1899-1902
A paper investigating American opinion and activism during the South African War of 1899-1902, with a special focus on the ways in which the war reflected Americans\u27 unease over their nation\u27s identity at the dawn of the twentieth century
Application of Theodorsen's Theory to Propeller Design
A theoretical analysis is presented for obtaining by use of Theodorsen's propeller theory the load distribution along a propeller radius to give the optimum propeller efficiency for any design condition.The efficiencies realized by designing for the optimum load distribution are given in graphs, and the optimum efficiency for any design condition may be read directly from the graph without any laborious calculations. Examples are included to illustrate the method of obtaining the optimum load distributions for both single-rotating and dual-rotating propellers

Comparison of calculated and experimental load distributions on thin wings at high subsonic and sonic speeds
A method for calculating the aerodynamic loading on a wing in combination with a body is presented. Calculated results are compared with experimentally measured data for two wing-body configurations throughout a range of Mach number up to 1.0. The magnitude and the distribution of spanwise loading of the calculated data are generally in good agreement with the experimental data
