Podgorny Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2  Algorithms and programs for calculating the dynamic instability of nanocomposite fairings for launch vehicles in a supersonic gas flow have been developed. A program for calculating the unsteady response of a nanocomposite body of a solid propellant engine, which consists of two spherical and cylindrical shells, has been developed. The type of nano-reinforcement can be arbitrary. The process of developing programs for calculating the dynamic instability of the fairings of launch vehicles and the stress-strain state of the tanks of a solid propellant engine made of nanocomposite materials is described, these programs and results of their verification and validation tests are presented. A mathematical model of the non-stationary response of the rocket adapter made of a nanocomposite conical shell reinforced by upper frame is constructed. The obtained model was verified by comparing it with the calculation results in ANSYS. Product Description popup.authors popup.nrat_date 2020-10-01 Close
