In this paper, the problem of numerical modeling of thermoelastic behavior of nose caps of hypersonic vehicles at different angles of attack is considered. 3D finite element modeling is performed by solving the coupled heat and elastic problems taking into account thermal and mechanical properties variations with temperature. A special method for calculating the aerodynamic heat flux entering the nose cap from its surface is proposed. This method is characterized by very low computational costs and allows calculating the aerodynamic heat flux at different values of the Mach number and angles of attack which may vary during the aerodynamic heating. The numerical results obtained by the proposed approach are compared with the numerical results and experimental data obtained by other authors. The developed approach has been used for studying the impact of the angle of attack on the thermoelastic behavior of nose caps main components. © 2017 IAA

The results of static strength tests of samples made from T700 carbon plastic with various thicknesses and packings of monolayers are given. The coordinates of the destruction range were determined and the loading values were chosen at which the destruction of samples is initiated. During the loading of samples, their state was monitored using the AE method and strain measurement. © 2016, Pleiades Publishing, Ltd.
