Optimization Method for Grading Civil Aircraft Cabin Space Under Airworthiness Regulations

Abstract

In the confined space of civil aircraft cabins with limited length and height, achieving a rational and efficient utilization of cabin space through the reasonable layout of cabin facilities, spatial allocation of seats, and equipment facilities is an important means to enhance the competitiveness of the civil aviation market, drawing significant attention from airlines. This paper proposes a graded optimization method for cabin layout that meets airworthiness regulations. By balancing and optimizing the requirements definition, influencing factors, and design conditions of cabin layout design, the method achieves an optimized arrangement of simulated cabins, ensuring both economic efficiency and improved passenger comfort. It provides valuable guidance for the cabin layout of civil aircraft and the redesign of in-service aircraft cabins.
