Study on Evaluation Method of Body Injury in Emergency Landing of Aircraft

Abstract

Body injury criterion is the basis of aircraft seat and restraint system design. On the base of statistics on 559 autopsies involved in fatal general aircraft accidents in Federal Aviation Administration's autopsy database, an analysis was performed to confirm the frequency and fatal risk in these aircraft accidents. Concerning different tolerance against impact of various body regions, the General Injury Criterion (GIC) was proposed to address the application in aviation, trying to provide an evaluation index for design and test of aircraft seat and restrain system. In union of seat dynamic test of a certain light amphibious aircraft for the airworthiness certification, the finite element model of the test was analyzed, and GIC was used to assess severe injury risk corresponding to various seat positions forward and backward. The assessment provides references in confirming testing condition of seat installed test.
