Abstract

Abstract:

A full-scale civil airplane fuselage section with 7 frames is designed and manufactured whose cabin section is configured with three rows of seats and two overhead bins. A finite element model of the fuselage section and cabin Interiors is developed, and a 7 m/s vertical impact condition is confirmed by two pretest analyses. The impact surface is a wooden platform instrumented with 12 load cells. The passengers are simulated by 15 dummies, of whom four are instrumented, and the passenger baggage is simulated by concentrated weights. The impact loads and acceleration responses of the structure and dummies are collected by a data acquisition systems (DAS) which is synchronized to high speed cameras. Experimental data processing methods are introduced and typical experimental curves are presented. The energy absorption process and mechanisms of the fuselage section during the impact are estimated, and three general methods of improving the fuselage structural crashworthiness are proposed. Based on the structural requirements and human injury criteria of the transport airplane airworthiness regulation, a crashworthiness evaluation method called the integrated crashworthiness index (ICI) is introduced, which can score the crashworthiness with a standard formula. The crashworthiness of the fuselage section structure is evaluated with ICI. The evaluation result show that the fuselage section structure meet the crashworthiness requirements well under the given impact environment.
