民用飞机迫降后不利姿态应急撤离实验研究

Based on dynamic emergency evacuation test environment, the effects of adverse attitude on emergency evacuation were studied and more than two hundred tests, including individual evacuation and group evacuation tests, were implemented. Then the average evacuation speed of individuals at seat and aisle area was analyzed according to free walk and quick evacuation model, with the results of which models of individual average speed attenuation ratio was established. The tests show that the adverse attitude of landing has effects on evacuation time, personnel density and forward distance. Under roll condition, the speed attenuation ratio is 0.948 and 0.859 at 5 degrees and 10 degrees, respectively, declining with the increase of the roll angle. Under pitch condition, the effects of acceleration appears at −5 degrees and the evacuation speed of the last person is 1.35 meter per second, with speed attenuation ratio increasing with the evacuation sequence; while at −10 degrees, the individual movement displays two-sidedness, with the speed in inverse proportion with the evacuation sequence. The test results reveal the movement patterns of the individual and group evacuation under adverse attitude landing condition and provides important reference data for evacuation simulation of civil aircraft.
