The Swedish Sea Rescue Services (SRSS) has developed an Unmanned ArialVehicle (UAV) which they use for search and rescue missions. The SRSS wantsto upgrade this UAV to also be able to fly and drop with a package. Bydesigning according to the model of designing by HH van den Kroonenberg [2].The main functions for the package is that it needs to be able to carry at least 300gram and be 900x900x25 millimetres big. After designing 3 concepts, one mainconcept is chosen and produced as a Solidworks model. This package and thejoint to hold the package have been designed and have been calculated to be ableto withstand the stresses during flight. The stresses include the weight of thepackage as well as the aerodynamic drag. With a safety factor of 1.5. Also afinite element simulation is done to check the main stresses, this simulationshows that the critical beam will not be able to hold. It is recommended that amore dense EPP is used or the beam will be redesigned. Also an engineerspecialized in aerodynamics is recommended to take a look at the results to befully secure.
