Future of the Aircraft Industry


The Hispano-Suiza Airplane Engines

Owing to the veil of secrecy which has surrounded the Hispano-Suiza engine in this country up to the present time, the American public does not know that this engine has been characterized as second only to the Liberty as a factor in the air program of the United States.

The L-W-F Model G-2 Fighting Airplane

Since the entry of the United States into the World War. no all-American designed fighting airplane has been used at the front. In the great rush and hustle to get American-made fighting machines to the battle front, no time was given American engineers and designers to perfect any partially constructed or designed machines of the type required.


Future of the Aircraft Industry

In giving consideration to the future of the aircraft industry, considerable thought must be expended in order to retain the picture within its proper limits of perspective, for while it is certain that the progress of the aircraft industry will be very rapid and will reach into fields hereto unknown or unsuspected, it is reasonable to state that those developments will be along sensible lines.

Organizing for Aircraft Production

Factory organization varies greatly in all branches of industry and even among plants turning out similar products While plants can be operated successfully with wide differences in the organization of their personnel, there is no doubt that a careful arranging of the force—holding in mind both the calibre of the men available and the adaption of the organization to the work—is of incalculable value in preventing the overlapping of authority, locating responsibility where it belongs and generally facilitating the operation of the plant to the best advantage.


New Type of Rotary Engine

It does not require demonstration to state that no other single factor has had such a far-reaching influence on the prewar development of the airplane as the rotary engine, and particularly its first successful representative, the Gnôme.
