This paper is focused on creation of the tail unit FEM strength analysis of the UAV based on helicopter by advanced CAx tools. To perform the analyses were used advanced information technology tools with high precision. For the strength analysis was used solver NASTRAN as a part of software NX. This analysis has shown us, in which locations of the surface design will be the greatest loads during the flights operations and in which points of attachment of the tail unit together with fuselage will be the greatest st...
