Design of a cargo load carryingstructure for a hybrid air vehicle

Sammanfattning: Recent developments in aeronautics have resulted in hybrid airships, a combination of aerostats and aerodynes with the ability to land without infrastructure and using minimal ground crew. This work explores the possibility of using a non rigid type of these vehicles for cargo transportation. To do so, a load carrier able to transfer the load to an allotted set of attachment points under the soft hull of the airship is needed. A short prestudy examines the limits and feasibilities of potential cargo-types and concludes there are three characteristically different problems that can be combined to represent most realistic load cases. A modular carrier system is then created with modules corresponding to each problem, and suitable dimensions are chosen by finding the relations to the resulting stresses and deflections.
