This task is put on the development of the methods to optimize the stress-strain state wing aircraft under the influence of arbitrary external and internal pressures. The paper proposes rigidity interpreted as a variable that depends on the configuration of power elements, varying the location of which can be achieved by maximizing stiffness. We defined the mathematical function of mass and stiffness depending on the internal configuration of power elements (plating, stringers, longerons). The wing has the power elements, the placement of which may be various: power paneling, two longerons and stringers, four on the bottom and top panels. As a result, on the basis of the spatial theory of elasticity were obtained equations describing the bending, torsional and longitudinal vibrations of the wings, and the proposed mathematical model of the optimal hardness wing by varying the functional dependence for placing power elements and varying the parameters of this function. The results made it possible to optimize the internal structure in terms of minimum deformation at constant values of the mass of the investigated structures such as wings to reduce bending, twist angles and tensile strength elements.Бтавится Π·Π°Π΄Π°Ρ‡Π° ΠΎΡ‚Π½ΠΎΡΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎ Ρ€Π°Π·Ρ€Π°Π±ΠΎΡ‚ΠΊΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΈΠΊΠΈ ΠΎΠΏΡ‚ΠΈΠΌΠΈΠ·Π°Ρ†ΠΈΠΈ характСристик напряТСнно Π΄Π΅Ρ„ΠΎΡ€ΠΌΠΈΡ€ΠΎΠ²Π°Π½Π½ΠΎΠ³ΠΎ ΡΠΎΡΡ‚ΠΎΡΠ½ΠΈΡŽ ΠΊΡ€Ρ‹Π»Π°, ΠΊΠΎΡ‚ΠΎΡ€ΠΎΠ΅ находится ΠΏΠΎΠ΄ дСйствиСм ΠΏΡ€ΠΎΠΈΠ·Π²ΠΎΠ»ΡŒΠ½Ρ‹Ρ… Π²Π½Π΅ΡˆΠ½ΠΈΡ… ΠΈ Π²Π½ΡƒΡ‚Ρ€Π΅Π½Π½ΠΈΡ… Π½Π°Π³Ρ€ΡƒΠ·ΠΎΠΊ.
