Present Day Problems in Aeronautics

Airplanes as at present constructed can never become an industrial proposition nor be feasible for commercial work. A radical change in airplane design, if not in theory, will be necessary before air travel, aside from war conditions, can be a commercial success.


The Aircraft Situation

While the time is past when it seemed advisable to emphasize the difficulties which have delayed the aircraft production during the past year, except as they may indicate a way of obviating these difficulties in the future, any survey of present aircraft production must refer to some extent to these difficulties.

The Orville Wright Banquet

C. F. Kettering, president of the S. A. E., acted as toastmaster of the banquet given in honor of Orville Wright, at which speeches were made by Howard E. Coffin, Colonel E. A. Deeds, Colonel J. D. Vincent, Lieutenant M. Miozzi of the Italian aeronautics commission; F. G. Diffin, assistant director aircraft production; C. M. Manley, member of the American aeronautical commission to France, and Dr. S. W. Stratton, director national bureau of standards at Washington.

Airplanes of Today

No subject, if we are to believe the press today, is of more interest to the world at large, and the United States in particular, than that of aviation. This is naturally so because of its supposed vital bearing on the outcome of the war, and because it bids fair to usher in a new and yet unexplored commercial era afterward.


Exhaust Headers and Mufflers for Airplane Engines

Chief Engineer, L.W.F. Engineering Co. In the following notes no attempt has been made to treat exhaustively the design of exhaust headers or mufflers for airplane engines. The paper is intended chiefly to record some data collected on this subject during the past several years.


The Airplane Problem

Much has been written about the aircraft situation and its personnel both past and present. The industry has been the mark of investigators and the investigation of investigators, and now, at last, we seem to be safely started on the right path to production.


Digest of the Foreign Aeronautical Press

The Hannover Biplane—The machine illustrated by the accompanying drawings was captured practically intact and belongs to the C class of general utility machines. It is of comparatively recent manufacture, as several parts were stamped with the date 19/12/17.

News of the Fortnight

The Senate on June 19 passed the Senate bill 3524 to extend temporarily the time for filing applications for patents and registration of trademarks, etc. In the trading-with-the-enemy act it is provided that Germany and her allies may file applications in this country more than a year after having been filed in their own countries, whereas a citizen of a country allied with the United States must file in this country within one year from the time the application is filed in his own country; otherwise his patent when taken out here is invalid.

Washington Views on Production

For several weeks two separate investigations into distinct phases of the aireraft situation have been conducted. They are still in progress. One outside of Congress is to determine whether, as alleged, there have been irregularities or criminal delinquencies, and one by Congress is making an inquiry into production.

The Clement-bayard Rigid Airship

It is a little known fact that, though the rigid airship has been chiefly developed in Germany, particularly through the efforts of the Zeppelin and Schütte-Lanz concerns, the basic elements of this type of aircraft were first patented in 1873 by a French engineer, Joseph Spiess, a native son of Alsace.
