International Aircraft Standards

GENERAL.—1. The general specifications, 1G1, shall form, according to their applicability, a part of these specifications. MATERIAL.—2. The material for these sheets shall be chosen from the I. A. S. B. standard alloy steels listed below.

The Modern Zeppelin Airship

The capture, by French aviators, of the German naval airship L-49 on Oct. 20, at Bourbonne-les-Bains, has lifted the veil of secrecy which surrounded the constructional details of Zeppelin airships since the outbreak of the war. The L-33, which was brought down by British aviators a year ago in Essex, already gave certain indications of the improvements embodied during three years of warfare, but as the vessel was burned by its crew these indications were necessarily incomplete.


Appropriation of $1,126,654,260 Asked for Aeronautics

Over one and an eighth billion dollars for aeronautics were asked for in the budget submitted to Congress on its opening day by the Secretary of the Treasury, in addition to the large sum separately listed for the pay of officers and enlisted men.

The Use of Steel in Airplane Construction

The growing scarcity of the woods used in airplane construction gives rise to the consideration of other materials suitable for this purpose. In this discussion, the use of steel will be investigated and an effort will be made to remove the prejudices existing against the use of this material.


Radiators for Airplane Engines

The Auto Radiator Manufacturing Corp., manufacturer of the “Flexo” copper core radiators has investigated the problem of airplane engine radiators in a thorough manner and some interesting results are available. Data was obtained from field tests.

The Austro-Hungarian Seaplanes K.301 and A.25

This machine was brought down by Italian aviators in the night of Jan. 12, 1917, and has proved a highly interesting specimen of Austrian seaplane construction, both because of its intrinsic qualities and because of the recent date at which it was captured.

Government Specifications for Kiln-drying Airplane Woods

Inability to secure an adequate supply of three-year, airdried spruce for airplane work has led the Aeronautical Engineering Division of the Signal Corps of the United States Army to develop process specification number 20,500, providartificial drying of lumber.
