Two Hundred Books on Aeronautics

Of the one or two thousand existing books on aeronautics only a few are of real value; it is estimated that over 80 per cent of the total number may be disregarded by students. This was found to be the ease in establishing the comprehensive aeronautical collection of the University of Illinois library; for by culling out the books of little value it has been possible to cover the field with a comparatively small list of titles.

Course in Aerodynamics and Airplane Design

One of the most difficult problems in aeronautics is the estimate of the worst loads likely to come on under unusual circumstances, on which alone correct allowances for factors of safety can be based. In speaking of factors of safety, a distinction must be made between the load factor of safety and the gross factor of safety.

The Construction of Airplane Propellers

There are a large number of woods used in the construction of airplane propellers and the selection of one suitable to meet the conditions in hand is not always an easy problem. The woods most commonly used in American practice are: birch, Honduras mahogany and white oak.

The Accuracy of Modern Aero-tachometers

A series of experiments, to determine the accuracy of aerotachometers, have been made at the Massachusetts Institute of Technology by the Electrical Engineering Department. Tests were made on two tachometers, one manufactured by the Reliance Speedometer Company, and the other by the Stewart-Warner Company.
