The purpose of this paper is to make an analytical comparison of two vertical tail models from a structural point of view.


The original vertical tail design of PZL-106BT aircraft was used for Computer aided design (CAD) modeling and for creating the finite element model.


The nodal displacements, Von-Mises stresses and Buckling factors for two vertical tail models have been found using the finite element method. The idea of a possible Multidisciplinary concept assessment and design (MDCAD) concept was presented.

Practical implications

The used software analogy introduces an idea of having an automated calculation procedure within the framework of MDCAD.


The aircraft used for calculation had undergone a modification in its vertical tail length, as there was an urgent need to calculate for the plane’s manufacturer, PZL Warszawa – Okecie.
