Experimental and simulation on emergency evacuation of passenger in wide-body aircraft under tilted attitude

Abstract

Abstract:

To explore the influence of tilted attitude of wide-body aircraft on the emergency evacuation of cabin passenger, a

combination of cabin partial evacuation test and full-size simulation test is used to analyze the key factors such as

evacuation time. Based on the scenario construction theory and social force model, the relevant parameters in the

full-size simulation model are modified with real test data of partial evacuation, and then the full-size simulation

model is used to conduct the simulation test of passenger evacuation under cabin tilted attitude, and the increase

model of the average evacuation time of tilted attitude is established. The test data show that the inclination attitude

angle of the aircraft has an effect on the evacuation process and efficiency. Under pitch attitude, pitch ±5 degrees

has a positive effect on the evacuation efficiency, evacuation efficiency is -0.044 at pitch -10 degrees. Under

roll posture, roll angle has a significant negative correlation with evacuation efficiency, and the evacuation efficiency is -0.073 at roll ±10°. The results show that the data deviation between simulation model and real test of partial

evacuation is 6.54%, which is in the acceptable range. The full-size simulation model can accurately simulate the

effects and change rules of passenger emergency evacuation under the tilted attitude of the cabin, and can provide

references for the safety evaluation of the design, manufacture and operation of passenger aircraft.

Key words:
