Abstract:

This document presents the results of a study commissioned to update the kinematic design criteria for helicopter crashworthiness. The study, conducted by Simula Aerospace and Defense Group, Inc. Simula, reviewed crash kinematic data over the past 25 years with the objective of identifying new trends in crash parameters and revising the associated design criteria accordingly. The objective of this study is to update the impact design criteria for crashworthiness by studying the crash kinematics of four currently active U.S. Army aircraft specifically, the CH-47 Chinook, the OH-58, the UH-60, and the AH-64 Apache. No variants of these aircraft were excluded from the study, but a few specific models did not appear in the final list of mishaps. As a part of this update of the impact design criteria, kinematic data were collected and are presented in a manner intended to facilitate easy comparison with earlier studies.
