V.; Shulzhenko N.G., Registration Date 17-03-2014 Organization A.Podgorny Institute for Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2 Dynamic strength of space system elements under the action acoustic and impulse forces are analyzed. The methods of aeroelastic vibrations analysis for the rockets deflectors in a supersonic gas stream are developed. The mathematical model of shells flowing in supersonic stream is obtained. The analysis of gas stream descriptions confirms possibility of application of quasi-static theory of supersonic flow. On the base of two methods, the dynamic responses of the space vehicle elements are developed. The operation of pyrotechnic device is taken into account. The software for calculation of dynamic response is developed. Graphical interfaces are contracted. The dynamic responses of the rockets adapters are calculated. The Rayleigh - Ritz method, finite difference method and finite element method is used in this software. The results of this project are used in Ukraine rockets industry Product Description popup.authors Єфремов Юрій Геннадійович Аврамов Костянтин Віталійович Асайонок Олександр Вікторович Воробйов Юрій Сергійович Гонтаровський Павло Петрович Депарма Галина Олексіївна Зайцев Борис Піліпович Кашкова Ірина Леонідівна Колядюк Андрій Сергійович Матюхін Юрій Іванович Печерська Ольга Максимівна Протасова Тетяна Володимирівна Романенко Валентина Миколаївна Чернобривко Марина Вікторівна Шульженко Микола Григорович popup.nrat_date 2020-04-02 Close
