The task of the thesis is to optimize the wing structure of a non conventional very
light airplane starting from a Prandtl Plane prototype currently in phase of develop-
ment. This treatment is divided in several parts. In the rst part an introduction
about the main features of Prandtl Plane aircrafts is given.
In particular, the rst chapter explain what was the idea which led to this new
solution, its main advantages and the reasons which led to employ this conguration
in the branch of light aviation.
The second part depicts all the features of the prototype, in terms of regulation
observed, structures, materials used to build it, and loads that act on the structure.
The third part aims to the describe the optimization process and how the code used
to implement it works, starting from a previous tool and showing how this process can
be used in order to allows later development of this conguration.
Finally, in the third and last part of this job the results of the optimization pro-
cess will be veried through a nite element analysis, in order to allow a comparison
between the prototype and the optimized structure.
