This paper considers the methodology of modular combinatorial-variational geometric modeling for technical objects on the example of automated shaping of some typical airplane structural elements.Stringers, beams, frames, spars, etc. were analyzed. Parametric geometric models of these objects were built. The models were combined with structural and parametric tools for effective computer-aided design.The proposed modular approach allows you to improve the performance of the creation processes of complex equipment. These simulation tools can successfully implement a comprehensive optimization of industrial products throughout their life cycle.It is possible to integrate computer structural-parametric geometric models stringers, beams, frames, spars, ribs, etc. with their design, technological and operational models in computer-aided design.The proposed approach is illustrated by computer model created in the environment of the software package SolidWorks. The curves of the second order in the rational parametric form were used for this purpose. Based on them, structurally-parametric solid models of the elements of the aircraft structure were built. Kinematic shaping techniques have been widely used in solving these tasks.Summary of the application of elaborated design techniques in other CAD/CAM/CAE systems to develop such parts and components of aircraft has been made.This applied research area automation design of complex modern techniques has good prospects for further development. However, it needs to carry out further intensive research of such sciences as geometry, design of aircraft, its aerodynamics and strength, manufacturing technology and exploitation to integrate successfully by means of computer information technologies.
