Overview of Structural Behavior and Occupant Responses from a Crash Test of a Composite Airplane 951168

As part of NASA's composite structures crash dynamics research, a general aviation aircraft with composite wing, fuselage and empennage (but with metal subfloor structure) was crash tested at the NASA Langley Research Center Impact Dynamics Research Facility. The test was conducted to determine composite aircraft structural behavior for crash loading conditions and to provide a baseline for a similar aircraft test with a modified subfloor. Structural integrity and cabin volume were maintained. Lumbar loads for dummy occupants in energy absorbing seats were substantially lower than those in standard aircraft seats; however, loads in the standard seats were much higher than those recorded under similar conditions for an all-metallic aircraft.
