A full-scale crash test of a CH-47A troop/cargo helicopter was conducted at the NASA-Langley Research Center Impact Dynamics Research Facility. This joint Army/NASA/Navy test program was performed as part of the Army's continuing research and development program to enhance the crashworthiness of helicopters. This report describes the structural crashworthiness, the load attenuating cargo restraint, and the aircrew inflatable crew restraint experiments that were conducted, and presents the resulting data. The test aircraft crashed with a 9-degree nose-down attitude; this impact was representative of the 95th percentile potentially survivable accident crash pulse. Results of the test can be compared with those of a CH-47C crash test (T-39) conducted in 1975, which impacted at a 10-degree nose-up attitude with approximately the same resultant impact velocity vector.
