Review on the design of an aircraft crashworthy passenger seat

In this article, based on a broad review of the literature, a comprehensive overview of the global state-of-the-art in the development of aircraft passenger seat crashworthiness is disclosed. With the increasing usage of aeronautics as means of transport in everyday life, the probability of accidents and injuries has also increased. This trend leads back to the top priority for the safety of human life and consequently the effort of the worldwide designers. Following a large number of studies coming from different industrial branches, military organizations, and academic centers on aircraft, this article presents a review of the crashworthiness of aircraft passenger seats from the aspect of research approaches, accident investigations, mechanism analysis of occupant injuries and aircraft damage, strategies of occupant protection, and crashworthy design (crash energy management design) and performance of aircraft structures during collision scenarios. Finally, it is concluded by outlining trend in scientific research regarding the improvement of aircraft seat structure design and material composition, in order to significantly increase the overall crashworthiness of the aircraft.
