Abstract

After a five year study of General Aviation (GA) accidents, the National Transportation Safety Board (NTSB) has concluded that aircraft cabin environments place the occupant at high risk of suffering severe injuries in an emergency crash situation. Studies of Federal Aviation Administration (FAA) seat tests were used to form the basis of a computer analysis to address dynamic cabin environments. In this effort a simplified system of masses, springs, and dampers are used to simulate the more complex configuration of cabin structure, seat, pilot, and restraints on a personal computer. The primary objective of this study is to accurately simulate the motions observed in real life tests performed at the FAA Civil Aeromedical Institute (CAMI) with a commercially available dynamics software. Working Model® was chosen based on its performance, availability, and cost. Design students can use the simulation to evaluate cabin arrangements early in the design phase, making for a useful design tool.
