A deformation criterion of pressurized non-circular cross-section cabin and its effects on cruise performance of BWB civil aircraft
《Chinese Journal of Aeronautics》2024年第6期78-88,共11页Siyi GUO Zhenli CHEN Xuanyu YAO 
supported partially by the National Key Laboratory Project,China(No.61422010201).
Blended-Wing-Body(BWB)aircraft is promoted as one of the most possible layouts to achieve more sustainable civil aviation.Due to the non-circular cross-section of the center-body,a bulge deformation forms over the upp...
