Book Description
This paper contains an analysis of the applicability of the statistical theory of extreme values to the problems of predicting the frequency of encountering the larger gust loads and velocities in flight through rough air. The results indicate that the distribution of maximum values of gust loads and velocities, under both test conditions and in normal commercial transport operations, may be represented by a simple analytic form. Methods of application and methods of measuring the reliability of the estimates are also given.

Book Description
Theoretically derived charts showing steady-state and first- and second-harmonic flapping coefficients are presented for helicopter rotors having hinged rectangular blades with a linear twist of 0, -8, and -16 degrees. The charts, showing the rotor flapping coefficients for combinations of inflow ratio and blade pitch angle, are presented for tip-speed ratios ranging from 0.05 to 0.50.

Book Description
Available information on the hail phenomenon affecting aircraft in flight has been examined. This paper attempts to coordinate the present knowledge of hail with the effect of hail on aircraft in flight and includes (1) a digest of the literature on the physical properties, the occurrence, and the formation of hai; (2) a survey of the hail effect on aircraft in flight from analyses of 57 cases of airplanes damaged by hail; (3) a resume of hail information for the benefit of pilots, forecasters, and ground operational personnel; (4) an annotated bibliography of 552 articles for use of research personnel.
