ABSTRACT

The advent of Blended Wing Body (BWB) configurations in commercial aviation presents new opportunities and challenges for passenger safety and comfort. This study investigates seat layout optimization and evacuation dynamics within BWB aircrafts which feature a wide and non-linear cabin, which complicates optimal exit placement and aisle accessibility.

Computer Aided Design (CAD) and simulation are used to identify optimal seating layouts that minimize evacuation time. Human movement and behavioral factors are incorporated to evaluate multiple seat configurations under regulatory evacuation standards. The influence of aisle placing, exit placement and light guidance systems on passenger flow continuity is also analyzed.

The findings provide actionable design insights for future BWB commercial aircrafts, balancing safety compliance, passenger comfort, and operational efficiency.
