Based on airworthiness compliance and considering of structural space, the cabin layout design for a BWB civil aircraft is carried out with constraints in aisle width, maximum number of seats abreast, emergency exit arrangement, emergency evacuation, flight attendant seats, lavatories, and galleys arrangement. A typical 2-class cabin layout of 382 seats is designed, containing 2 pairs of Type A exits on both sides of the front centerbody, 4 Type A exits on the bottom of the rear center-body, 4 longitudinal aisles, and 5 cross aisles. This cabin layout can meet the airworthiness for aisle width, maximum number of seats abreast, type of emergency exit, emergency exit uniformity, emergency exit access, number of flight attendants, and flight attendants vision. Compared with the conventional civil aircraft with similar seats, the layout has higher longitudinal and vertical space comfort. The business class seat pitch is about 58% higher, and the head space of the passengers near the cabin sidings is about 4%-18% higher; but the lateral space comfort is slightly worse. The emergency evacuation simulation system analysis shows that the layout meets the requirement of "90 s emergency evacuation".
