Create any aircraft (LA) - a process long and complex, the result of joint efforts of the vast collective set of divisions and departments. By LA imposed a significant number of different requirements, which in comparison with the requirements for other engineering structures and ma-tires are much more complicated. LA must have a good performance data (speed, ceiling, range, etc.) and at the same time it must be robust enough to operate at minimum weight design.
Strength calculations are one of the most important stages of the creation of aircraft. During their execution are determined stress and deformation structure elements of aircraft and Me-todami means of structural mechanics, using the results obtained in the theory of plasticity and creep, as well as the theory of plates and shells. When compared with stresses found destructive and deformations - with normalized possible sous-dit of sufficient or insufficient strength and rigidity permissible. Recent advances in the development of methods for the calculation of technical objects on the strength-that enable you to perform such calculations in the shortest possible time, with high precision and certainty. One of the basic methods of calculation of complex engineering systems is the finite element method, successfully implemented in modern software Russian manufacture APM WinMachine / APM Civil Engineering. This complex is combined with the computing power of modern computer technology makes it possible to effectively fulfill all tasks required to perform deposits of engineering analysis, including calculations on strength, reliability and optimal design, as well as an assessment of their dynamic characteristics. Such deep and complex-tion analysis is needed both in the preparation of design documentation, and for the mo-simulation of technological processes. Because today's computer tech-nology are able to simulate the operation of any structures and analyze their behavior at the stage of preparation of the design decisions, the analysis of possible Modi-fication allows you to select the most efficient design proposal that minimizes costly prototype testing or full-Stu abandon such tests.
