Podgorny Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2 A three-dimensional model of a cooled single-crystal blade of a gas turbine engine has been developed, taking into account structural and technological features, shape and inhomogeneity of the material. A general method for calculating the gas-dynamic flow in the compressor of a gas turbine engine is developed, taking into account the interaction of blade oscillations and flow parameters. A computational approach and a mathematical model for the analysis of the process of high-speed elastic-plastic deformation are proposed, taking into account the material inhomogeneity of structural elements both initially given and that which arises in the process of high-speed deformation. An approach and a method for solving the problem of inelastic deformation of shells taking into account the damage of the material with subsequent fracture are proposed. Numerical analysis of steam flow and thermal conductivity in the steam distribution system on stationary modes of the K-325 turbine operation at different power in three-dimensional setting is developed. The method of analysis of eccentric mechanisms bearing shafts durability on the basis of finite-element modeling is offered. The calculation method of destruction of combat equipment of the missile complex under the action of internal shock pressure and the method of computer modeling of warhead transportation are offered.
