The Avorio-Prassone kite balloon was designed jointly by Major Luigi Avorio, Chief of the Aeronautical Division of the Italian Army, and Dr. Eugenio Prassone, Director of the Stabilimento Construzioni Aeronautiche. It was used extensively for observation purposes in the Italian Army.
In aerodynamic wind tunnels the air is sucked through the tunnel by a propeller or fan. There must, therefore, be a gradual increase in static pressure along the air stream from propeller to inlet section. By employing the static pressure openings of a Pitot tube, which has been shown to be a very reliable instrument for this purpose, and using a sensitive differential manometer, these pressures can be easily measured at several points along the tunnel, especially in that portion where the models are set up.
Characteristics of Design Effecting Production, Operation and Maintenance of Aircraft
Maj. Percy Bishop
The advent of the use of aircraft for purposes other than warfare will involve the appearance of several additional aspects into the already numerous considerations which have to be applied during the evolution of the design of an aircraft.
The Claudel carburetor, widely used in Europe for twenty years, is now made in America by the Claudel Carburetor Co., Long Island City, N. Y. This highly-perfected, plain-tube mixing device was designed by Charles Henri Claudel, the pioneer in the development of the plain-tube type of carburetor, who is recognized as the foremost European authority on carburetion.
APPLIED AERODYNAMICS By Leonard Bairstow (Longmans, Green and Co. 565 pp. with many illustrations and diagrams.) The publication of Mr. Bairstow’s book constitutes somewhat of an aeronautical event. Mr. Bairstow’s reputation is perhaps, as high as that of any aerodynamicist.
The term Lift as applied to airships is equivalent to buoyancy, and like buoyancy, when applied to water-borne ships, it depends on two considerations :— (1) The weight of the ship. (2) The weight of supporting medium displaced by the ship.
