Direct Solution of Airplane Spar Design

Until this time, to the writer’s knowledge, there has been no attempt made to develop any procedure whereby an airplane wing spar may be designed directly, without recourse to trial and error. The so called precise method recently adopted by the Air Service and the Navy Department, although somewhat more laborious as used at present, may be so simplified by a few very reasonable assumptions as to make it possible to solve directly for the location of the struts in a biplane truss.

Publisher’s News Letter

Now that the National Air Transport has ordered ten Carrier Pigeons to start its New York-Chicago service, there will be some figuring done as to just how much flying these planes could do. As the N.A.T. does not plan to fly Saturdays or Sundays, the number of round trips per year may average about 250, making allowance for holidays and trips cancelled on account of bad weather.

Cleveland, Ohio

Glenn L. Martin, governor of the N.A.A. for Ohio and president of Cleveland Chapter, has been appointed chairman of the Organizing Committee to help the city celebrate the opening of its new Municipal Airport on July 1. As Mr. Martin’s experience with humanity has led him inevitably to the conclusion that the great need of man is food—and possibly drink—the Cleveland Chapter N.A.A. is giving a grand aviation dinner in Cleveland Public Auditorium one of the largest halls in the world.

Milwaukee, Wis.

After reading some of our Milwaukee newspapers for the past month, one would get the impression that the most important thing in life, with the possible exception of finding a cool spot in which to live, would be to establish an airport here, located somewhere in the vicinity of some of our tallest buildings, where the tired business man might get a little relaxation by looking out his office window and watching the air traffic go by.
