Abstract

Since the summer of 2013, five full-scale crash tests have been conducted at NASA Langley Research Center’s (LaRC) Landing and Impact Research Facility (LandIR) on deformable airframes for the evaluation of a variety of crashworthy concepts. Two tests were conducted on two CH-46E “Sea Knight” airframes as part of the Transport Rotorcraft Airframe Crash Testbed (TRACT) project and three tests were conducted on three Cessna 172 General Aviation aircraft as a part of the Emergency Locator Transmitter Survivability and Reliability (ELTSAR) project. Full field digital image correlation (DIC) data was obtained as a part of each aircraft’s experimental suite, thus giving insight into the crash severity and airframe deformation which occurred for each test [1].
