The Gust‐Load Problem: The Results of Acceleration Data Obtained on Large and Small Commercial Aeroplanes in America

THE highly complex character of the gust‐load problem and the lack of knowledge of gust structure have led to the general use of gust‐strength criteria for aeroplane wings that are based on the concept of a “sharp‐edged” gust in which the aerodynamic phenomena are assumed to obey the laws of steady flow.
