The Spinning Symposium of the S.A.E.

More than eight hundred factors, some of which are not important, determine the spinning characteristics of an airplane. Six expert opinions, all based on actual experience, show a definite need for scientific investigation of these factors after the nomenclature associated with the problem has heen clarified and standardized.

The Trend of Activities

INDUSTRY activity during the last few weeks seems to have been more prominent in the air than on the ground. There were, however, a few ground developments of interest and importance. Therefore, in the same manner that the airplane goes over the ground and then into the air we shall deal with ground activities before going up for altitude accomplishments.

The Airplane Weight Complex

ONE of the essentials of airplane design is the treatment of the weight problem. To design a plane around a given engine with a minimum of dead weight and a maximum of useful load, at the same time fulfilling demands for strength of all structural and control parts is indeed a problem.

Afterthoughts on the Races

IN MAKING critical comment on an aeronautical event it is convenient to draw a sharp line of division between policy or general plan and its execution. In judging of the success of a race meet, we have to ask ourselves two questions. First, what were the races designed to accomplish, how were they intended to accomplish it, and was the end a worthy one?

Weight Saving in Airplane Structures

Many estimates have been made of the money value of weight saved in airplane structures and there is probably no more important problem confronting the aeronautical enigneer. The papers herein reviewed have been prepared by two men who have had long and profitable experience in simplifying aircraft construction with this object in view.

How Chicago Took the Air Races

THERE has been much questioning among leaders of the aviation industry during the past few years as to just what good the National Air Race meets do for the aviation industry. This question is still open to much controversy. There is one significant phase of the race meets, however, which can be definitely determined, and that is the good which they do the aviation industry in the immediate locality where they are staged.

Designs at the National Air Races

Airplane designs, particularly those of the contesting machines at the Chicago National Air Races, showed little originality, most of the designs being developed along the same lines as previous racing craft. There were however, a number of technically interesting aircraft to be seen on the field at various times.
