Aerospace engineering

FRANCESCO BATTISTA

To be able to design an experiment to measure fluid dynamic phenomena. To be able to perform experimental measurements. To be able to analyse experimental data obtained by measurements.

The student will be able to design and build a wing with balsa wood and measure the aerodynamic forces on the wing through the use of the wind tunnel and the dynamometric balance. Moreover, the student will be able to disseminate the results in a public presentation and with a report of a maximum of six pages with a template distributed by the teacher.

Basic knowledge of aerodynamics

THEORY: Theory and practice of measurements in a wind tunnel by dynamometric balance.
PRACTICE:
1. Design a wing with care to the wing plant and tip.
2. Realisation of the wing model designed at point 1.
3. Aerodynamic Force measurements on the wing in a wind tunnel by dynamometric balance.
4. Analysis of the data obtained by experimental measurements.
5. Optimization of the wing performances.
6. Presentation of the results
7. Drafting of the report

The laboratory deals with one/two theoretical classes and experimental measurements in the fluid dynamics laboratory. The students will employ the wind tunnel and several tools measuring aerodynamic body forces.

Attendance is recommended to actively take part in the experimental campaigns.

The project consists of a scientific report and an oral presentation dealing with the experimental measurements performed during the laboratory and the comparison with the data available in the literature.

Design and build a wing with specific performances (decided by the students), and verify them in the wind tunnel by using the dynamometric balance.
