The results: natural vibration parameters of the stage and amplitude-frequency vibration characteristics of propellant components (PC) free surface in FC cavities are determined; critical conditions of PC surface disruption are determined; the levels of pressure vibration amplitudes acting in PC are determined. Calculated estimations of serviceability reserve of inside tank devices to provide PC continuity is obtained. Product Description popup.authors popup.nrat_date 2020-04-02 Close
