Abstract:

T-41 was jointly conducted by the Aviation Applied Technology Directorate and the NASA-Langley Research Center. The purpose of the effort was to assess the effectiveness of the structural crashworthiness features designed into the YAH-63 during a severe but potentially survivable accident and to evaluate the performance of several developmental crashworthy systems in a real-world helicopter crash environment. Because this was the first crash test of an attack helicopter and the first of a helicopter having designed-in crashworthiness, T-41 offers unique data for predicting the crash impact behavior of future helicopters.
