Aeronautic instruments

Aeronautic instruments

Date: February 1, 1924
Creator: Koppe, H & Everling, E
Description: The development of aeronautic instruments. Vibrations, rapid changes of the conditions of flight and of atmospheric conditions, influence of the air stream all call for particular design and construction of the individual instruments. This is shown by certain examples of individual instruments and of various classes of instruments for measuring pressure, change of altitude, temperature, velocity, inclination and turning or combinations of these.

Air admixture to exhaust jets

Air admixture to exhaust jets

Date: July 1, 1953
Creator: Sanger, Eugen
Description: The problem of thrust increase by air admixture to exhaust jets of rockets, turbojet, ram- and pulse-jet engines is investigated theoretically. The optimum ratio of mixing chamber pressure to ambient pressure and speed range for thrust increase due to air admixture is determined for each type of jet engine.

Air-flow experiments

Air-flow experiments

Date: May 1, 1924
Creator: Wieselsberger, C
Description: This report describes the apparatus used to take air-flow photographs. The photographs show chiefly the spiral course of the lines of flow near the tip of the wing. They constitute therefore a visual presentation of the phenomena covered by airfoil theory.
