Preliminary designs are evolved for five large logistic VSTOL configurations. Structural elastic characteristics and mass distributions are calculated. The structural dynamic response is investigated for ground landing, take-off abort, maneuvers, gust penetration and landing conditions. The results of this investigation are tabulated in a matrix showing the degree and relative criticalness for the conditions and the VSTOL configurations. The degree of criticalness is established as the ratio of the peak dynamic loading andor stress to the values used in the configuration design structural study. The latter structural loads andor stresses are evolved through the use of existing military specifications or normal design practices.
