Static and Dynamic Analysis of a Catapult for UAVs
This project was conducted for EADS-3 SIGMA S.A, regarding a static and dynamic analysis of a metallic construction which composes a launcher for Unmanned Aerial Vehicles. The purpose of this study was to check the strength of the construction, while subjected to loads occurring from its use, so that possible critical points can be defined and redesigned, resulting in validation of its credibility. The analysis was conducted using specialized Finite Element Analysis (FEA) software, and included:
Static Analysis
In this case, a total of 13 components of the construction were studied. The main frame is also included in these components. According to the construction material used, the strength of every part was defined, applying maximum loads that occur from the use of the launcher. The resulting stresses were calculated and it was checked if their values exceed material yield stress limit. For the components presenting stress values higher than the yield stress limit, recommendations were made for improvement and redesign.
Dynamic Analysis
In dynamic analysis, the strength of the main frame of the construction during the launch of a UAV was evaluated. All resulting stresses and deformations during critical moments of the launch were defined, so that safety of use is validated. The critical points of the construction were allocated and ways to improve its strength were proposed.
The project was funded by the EADS-3 SIGMA S.A.
