This research introduces a methodology for the automated sizing of airships. Considering an electricallypropelled platform, responding to the requirements of high-altitude pseudo-satellite mission, it is shown how an optimal sizing solution can be obtained, through an approach targeting total mass. After validating the design algorithm on an existing machine, the method is employed to explore the features of designs corresponding to different settings of the optimal problem. In particular, the geographical position and the stationing altitude are considered as parameters. Finally, optimally-designed machines are tested in off-design conditions, highlighting pros and cons in the proposed design approach.
