Aerial Transport and Travel

There is talk today of aircraft for transport and travel. The carriage of goods, mails, and people, the exploration of remote districts, the conduct of photographic surveys, the searching out of valuable trees in pathless forests, the speedy conveyance of officials to their administrations in distant climes—these things and others are everywhere hopefully dwelt on by the imaginative among those engaged in air work.

The Technical History of the Airplane

The history and development of mechanical flight may be confined almost entirely to the present century. In the last century some success had been achieved in gliding flight, model airplanes had been made and flown, and at least two man-carrying airplanes had actually left the ground, but it was not until the year 1903 that the Wright Bros., having ended a painstaking research in gliding flight, earned for themselves the honor of being the first men to fly.

The Design of Air Turbines

While air turbines have occasionally been used to pump gasoline from the main tank to an auxiliary, when it could feed by gravity, they were chosen for such purposes purely by a method of trial and error, and air turbine design did not really become important enough to warrant an attempt to establish it on scientific principles until the greatly extended use of radio apparatus, searchlights, stabilizer servomotors, etc., during the last few years, has made absolutely necessary the provision of satisfactory means, independent of the engine, for generating considerable quantities of electrical power.
