The Sperry Amphibious Triplane

One of the most important achievements in the development of American aircraft, is represented in the Sperry Amphibious Triplane. This development represents a feat that will tend to increase very considerably the usefulness of the airplane for naval and military, and commercial uses.

Fluid Resistance of Streamline Bodies *

The resistance offered by bodies to motion through fluids has for many years been a problem of the first importance, and one which has received a correspondingly large degree of attention both from scientific investigators and those commercially interested in the subject. A considerable amount of mathematical investigation has been carried out; but a detailed study of fluid motion has only proved possible in the case of a perfect fluid, i. e., one in which viscosity is not present.

The Short All Metal “Silver Streak”

The Short Brothers all metal “Silver Streak,” first exhibited at the Olympia show of this year in experimental form, is reported by the builders to have surpassed their expectations and to have brought a government order. The Silver Streak embodies the experience of this firm in the use of duralumin in airship construction, and is extremely interesting as an example of all metal construction, including metal wing covering in the girder type airplane, as distinct from the all metal internally braced machines, with which we have recently become familiar.

Personal Experiences in Constructing Metal Airplanes*

The lecture was divided into two principal parts, an aerodynamic part, treating of the birth of the original idea and invention and the exploitation of the same; and a structural part in which the construction of the metal airplane was described from the first trial piece to the finished vehicle for air traffic just as it had been developed by clear-sighted pioneering work from the airplane of pre-war times.
