Experimental researches on the resistance of air
Report presents the experimental results of the resistance of air of a body moving in relative movement to the air with which it is surrounded. digital.library.unt.edu/ark:/67531/metadc65630/
General specifications covering requirements of aeronautic instruments
Report includes specifications for the use and production of instruments used in the navigation and operation of aircraft. Specifications are included for the following instruments: barometer or altimeter, compass, air speed meter, inclinometer, drift meter, tachometer, oil gauge, oil pressure gauge, gasoline gauge, gasoline flow indicator, distance indicator, barograph, angle of attack indicator, radiator temperature indicator, gasoline feed system pressure indicator, sextant, airplane director. digital.library.unt.edu/ark:/67531/metadc65626/
Investigation of Pitot tubes
Report describes the principles of operation and characteristics of some of the instruments which have been devised or used to measure both low and high speeds of aeroplanes. Since the pitot tube is the instrument which has been most commonly used in the United States and Great Britain as a speedometer for aeroplanes, it is treated first and somewhat more fully than the others. digital.library.unt.edu/ark:/67531/metadc65620/
Investigations of Balloon and Aeroplane Fabrics

Preliminary report on the problem of the atmosphere in relation to aeronautics
A report to the Weather Bureau, Washington DC, from the chairman of the Subcommittee on the Atmosphere in Relation to Aeronautics describing the activities accomplished and the proposal of work to be undertaken by the subcommittee. digital.library.unt.edu/ark:/67531/metadc279504/
Relative worth of improvements of fabrics
Report presents an equation that connects all the major qualities of a fabric, from which the fabric may be rigidly designed with respect to maximum ultimate economy. digital.library.unt.edu/ark:/67531/metadc65622/
Report on behavior of aeroplanes in gusts
Part 1 presents the results of a wind tunnel test of a biplane model with an 18 inch span. The lift, drift, and pitching moment were measured for a series of angles of incidence corresponding to the maximum possible changes of flight attitude. Only the discussion of symmetrical or longitudinal changes is given. From the observed rate of variation of the forces and pitching moment, it was possible to calculate the derivatives needed in the complete theory of longitudinal stability in still air. The damping of the pitching oscillation was also determined experimentally. Part 2 presents a theoretical method for determining the effects of gusts on aeroplanes in the following cases: (1) head-on gusts rising from 0 to j feet per second with various degrees of sharpness, (2) up gusts of the same type, (3) rotary gusts of the same type, (4) rear gusts and down gusts are included by merely changing the sign of j. digital.library.unt.edu/ark:/67531/metadc65619/
Report on investigations of aviation wires and cables, their fastenings and terminal connections
Report presents results that show that it is possible to furnish efficient terminal connections that would allow for repairs for aviation wires and cables and eliminate the use of acid solder and blow torch. digital.library.unt.edu/ark:/67531/metadc65621/
