Structural response to discrete and continuous gusts of an airplane having wing bending flexibility and a correlation of calculated and flight results
Author(s): Houbolt, John C; Kordes, Eldon E
Abstract: An analysis is made of the structural response to gusts of an airplane having the degrees of freedom of vertical motion and wing bending flexibility and basic parameters are established. A convenient and accurate numerical ...
