The results of a study to develop simplified design procedures for determining nonlinear load-deflection characteristics for helicopter airframe structures are presented in a two-volume report. Volume one describes 60 technical reports and papers with regard to their applicability to crashworthiness analysis and designer-oriented procedures. Studies were made using an existing 31 lumped mass model of the UH-1H helicopter to determine the sensitivity of responses to changes in load-deflection representations. Twelve transmission pylon specimens were fabricated and static and dynamic tests were performed. (Modified author abstract)
