Π»ΡΡΠ°ΠΊΡΠ².The problem of the article is the optimizing of the internal structure of the wing with the purpose to improve its stiffness characteristics at a constant weight of the structure. 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.Π‘ΡΠ°Π²ΠΈΡΡΡ Π·Π°Π΄Π°ΡΠ° ΠΎΡΠ½ΠΎΡΠΈΡΠ΅Π»ΡΠ½ΠΎ ΡΠ°Π·ΡΠ°Π±ΠΎΡΠΊΠΈ ΠΌΠ΅ΡΠΎΠ΄ΠΈΠΊΠΈ ΠΎΠΏΡΠΈΠΌΠΈΠ·Π°ΡΠΈΠΈ Ρ
