Structural Design Of An Unmanned Blended-Wing-body Aerial Vehicle

This thesis presents the preliminary structural design and analysis of the Green Raven UAV, a blended-wing-body (BWB) platform developed by KTH Royal Institute of Technology to test a hybrid hydrogen fuel cell and battery propulsion system. In response to the aerospace industry’s increasing emphasis on energy efficiency and sustainable technology, the Green Raven aims to provide a viable foundation for future configurations of commercial wide- body aircraft. The primary design objectives are to develop a modular, lightweight structure that facilitates transport, ensures structural integrity under operational loads, and complies with regulatory weight constraints for UAV certification.
