Master thesis and internship[BR]- Master's thesis : Design of an aerobatic version of the Sonaca 200[BR]- Integration Internship

Abstract

By observing some acrobatic maneuvers, one can easily understand that they involve a large amount of various attitudes at a high rate. It is then obvious that higher loads are applied on the structure and thus higher stresses are also found inside the materials. Consequently, a specific aircraft are required. This type of aircraft has to be compliant with a specific standard that guarantees the integrity of the aircraft during this type of flight.

In this way, this master thesis consist in a structural analysis of the \textit{Sonaca 200} submitted to aerobatic loads. An estimation of these aerodynamic loads is performed through a panel method software. The latter enables to find the distribution of pressure all over the lifting surfaces. While corresponding stresses in each part of the aircraft are computed by finite element simulations of the whole airplane. The final goal is to determine which parts of the structure have to be reinforced.

This paper describes all the methodology as well as tools and models used. An example of the results are also presented and interpreted. These developments constitute a preliminary design to motivate future more advanced works.
