Airplane Wing Coverings

In the early stages of aviation little attention was paid to the textile materials used on an airplane. Further than insisting upon a wing covering of silk or linen nothing was specified. The weight per unit area of the fabric, the texture, weaving, the number of threads to the inch in the warp and the filling, and the question of elasticity in the warp and filling, were all neglected, presumably because everyone assumed that a fabric of silk or linen supplied every need of an airplane wing covering.

The Chicago Aeronautical Show

The Chicago Aeronautical Show, organized by the Manufacturers Aircraft Association and the first of its kind ever held in the West, will open in the Coliseum on Jan. 8 and will run continuously until Jan. 15. Most of the American aircraft manufacturers are exhibiting their latest products in this show and interesting displays will be made by the Army, the Navy and the Aerial Mail Service.

The Fiat 600 H.P. Aircraft Engine

It is only occasionally that we have the privilege of examining a new engine which reveals originality and initiative on the part of the designer in striking out boldly into departures not copies from other machines, and which does not savor of the "freak.”

The Farman Goliath Transport Airplane

The Farman Goliath transport airplane represents by virtue of its all-round performance a notable achievement in aeronautical engineering. This machine was originally designed as a long-range bomber, but as the armistice intervened before its construction was completed, the drawings were changed to allow for its use as a fast passenger carrier.

Editorials

THE annual report of the Secretary of the Navy contains, as may be expected, numerous references to the importance of aircraft in naval warfare. Some of these are highly significant insofar as they imply that our naval authorities are fully alive to the great changes the employment of aircraft will bring about not only in naval tactics and strategy, but also in the design and construction of warships.

Extract from Fifth Annual Report of the N. A. C. A.

The science and art of aeronautics made wonderful progress during the war, due to the stimulus of necessity. Over 11,000 aviators were trained in this country, with a loss of 264 lives in training, and more than 13,000 airplanes were constructed in the United States.

Micaria Airplane Propellers

While wooden propellers are rather satisfactory in service, they are very subject to changes caused by climatic conditions and have to be handled very carefully and inspected frequently in order to avoid the bad results of warping. Wooden propellers also wear out very rapidly from the effect of sand and small stones near the ground and from the effect of rain in the air.

Tests of Synthetic Gasoline

Following apparently satisfactory test block studies of a synthetic airplane engine fuel known commercially as Alcogas and composed of 38 parts alcohol, 19 parts benzol, 4 parts toluol, 30 parts gasoline and 7 1/2 parts ether, the Post Office Department arranged for a test of the fuel under service conditions in the Air Mail.

French Subsidies for Transport Aircraft

The French Government has decided to give financial support, annually, to French enterprises in aerial navigation, which have been legally formed and which have set up a public service, whether it be regular or irregular. The subsidies will be applicable for the period Aug. 1 to Dec. 31, 1919.
