The aim of the project is to develop and improve methods and algorithms for assessment of the thermal and deformed state of missile and space equipment structural elements and devices. The methods of influence evaluation of inhomogeneous temperature fields on deformation and strength as well as deformed state of aircraft panels under the influence of incompressible nonviscous potential flow are developed and improved. Algorithms for finite element calculation procedures are developed. The investigations directed to the verification of the thermal fields and the stress-strain state numerical modeling in general three-dimensional statement were done. The distributions of temperature and stress in the fiber optic gyroscope established onboard an artificial Earth satellite are received. The estimation of the damage in the model the polypropylene conductor was performed. The values of critical flow velocities and frequencies of autooscillations for aircraft panels at the case of their deformation in airflows are obtained. The nonlinear dependence of critical flow velocity from the panel curvature is obtained. Product Description popup.authors Аврамов К.В. Батюк О.А. Бреславський Д.В. Букрєєв М.В. Звонарьова А.П.
