BEDOYA VELASQUEZ, Santiago; RESTREPO AGUIRRE, Andrés Santiago; FEMANDEZ-MORALES, Patricia  and  MENDOZA, Emigdio. Comparison by computational modeling of mechanical performance of aeronautical parts made of magnesium and aluminum alloys. Prospect. [online]. 2017, vol.15, n.2, pp.26-32.

This study was focused on looking for potential replacement of parts made from aluminum alloys that are commonly used in the aeronautics industry. A part of a UH-60 helicopter, called support foot was analyzed, which is used in aircraft maintenance operations. For this part that originally is made of 2024-T3 aluminum, here is considered use to AZ31 magnesium alloy as possible substitute material for its manufacture, seeking to reduce its total weight without structural features changes. A finite element analysis software (ANSYS) was used in its structural analysis module, having the safety factor as main design criterion assessed respect to critical operation loads. A redesign was carried out to get a minimum safety requirement defined by aeronautical regulations, gotten huge possibilities of weight reduction on this part.
