The article presents the results of numerical simulations using the FEM (Finite Element Method) of the engine mount strength for mounting an aircraft diesel engine with opposite pistons called PZL-100. Four versions of the mount prepared by aircraft engine producer WSK "PZL-Kalisz" company were analyzed. Tests were performed in Catia v5 software in the Generative Structure Analysis module. The boundary conditions were engine gravity force, propeller thrust force, and propeller torque. S235JR steel was defined as the material. A design grid with tetrahedral elements with a single element size of 2 mm was used. As part of the simulation study, four structural solutions for the test engine mounts were calculated in terms of strength. The results of stress maps and the magnitude of deformation of the mount elements were compared. Based on the obtained results, one of the mount versions was recommended for actual fabrication.
