The paper presents a study of the technological process in automated fuselage panels jointing. The process includes the panels’ installation using the CNC positioners in the required position and subsequent connections jointing with the structure mating elements. Unlike the aircraft construction, the paper proposes to introduce an industrial manipulator instead of the positioning columns. Tooling is required to fasten the panels when using the industrial manipulator. Deformation of the skin edges that affects the assembly quality should be taken into consideration in the panel positioning. Study objective is the deformation process in the structure during positioning. The paper is devoted to analyzing options in positioning the attachment points of a typical helicopter panel when basing with an industrial manipulator. The analysis applied the finite element simulation in the Nastran NX software program. Deformation values for the edge sections of the reinforced and unreinforced typical helicopter skins were obtained. Based on the data obtained, recommendations are formulated for positioning the tooling attachment points to the panel.
