Crashworthiness analysis of commuter aircraft seats and restraint systems

摘要: Abstract During the past five years, U.S. Federal Aviation Regulations (FARs) have been significantly modified with respect to strength of seats and restraint systems, their attachments aircraft structure, means for evaluation. Aircraft accident data, human tolerance levels, structural characteristics considered in developing new standards, which require dynamic testing systems. FAR Part 23, deals small airplanes, was first amended systems normal utility (general aviation) capacity fewer than 10 passengers. Performance criteria are similar those specified by Motor Vehicle Safety Standards automobiles, but also include a limit on pelvic force order prevent spinal injuries that may be caused vertical component impact force. Similar regulatory actions, although requiring somewhat different test conditions, implemented transport aircraft, covered 25, helicopters, under Parts 27 29. Commuter-type not affected modifications. Commuter types seat 19 passengers, closer size general aviation large transports, 23. The Administration (FAA) is currently involved research program includes full-scale drop tests, sled tests seats, computer simulations should lead proposal amendment regulations commuter-type aircraft. objectives this paper describe document some conclusions drawn from its results concerning system design, testing, acceptance criteria.
