This Master’s thesis describes the results of the work developed for a specific experimental aerodynamic laboratory housed at the Technische Hochschule of Ingolstadt, Germany.
The present work consists in the design of an automated traversing unit that has to serve in a specific wind tunnel, which is currently equipped with a simple positioning system not operated by a computer and capable of performing a rotation just around a single axis. In this context, the design of a new traversing unit is considered a crucial element for the improvement of the future experimental analysis of the aerodynamic forces acting on a micro air vehicle.
After an initial critical analysis of the assigned requirements, different strategies to satisfy the imposed conditions are implemented and different conceptual solutions are realized.
The following step consists in the evaluation for merit of the different solutions suggested, selecting the one considered ideal for the fulfillment of the project.
Afterwards, the best configuration is discussed in deeper detail, optimized and finally developed.
All the results obtained in this section have to be considered the effect of a continuous cooperation between the Aerodynamics and Structure departments, including the respective workshops and laboratories.
As specifically demanded, a 3D model of all the components forming the traversing unit is realized, including the technical drawings and the specific structural tests for the elements considered critical.
The ultimate goal is the delivery of all the calculations, all the technical considerations and the programming elements considered necessary for the effective production of the traversing unit, within a predetermined deadline.
