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.
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.
Investigations of Balloon and Aeroplane Fabrics
Report presents the experimental results of fabrics used for balloons and aeroplanes. Tensile properties, surface roughness, skin friction, flammability, permeability, and water absorption were tested for different combinations of materials.
Meteorology and aeronautics
A handbook in which properties and general phenomena of the atmosphere which aeronauts and aviators should understand are discussed.
Mufflers for aeronautic engines
Report presents the design, development and experimental results of muffling devices used to reduce noise generated by the airplane power plant.
Nomenclature for Aeronautics
Report defines the principal terms which have come into use in the development of aeronautics. (author).
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.
Theory of an airplane encountering gusts 2
Calculations of aerodynamic effects of an airplane encountering gusts are presented.
