Computation of the POGO self-oscillation parameters in the dynamic "propulsion – rocket structure" system by using a 3d structural model
A mathematical model describing the nonlinear dynamical interaction of a launch vehicle (LV) and its marching liquid-propellant engine in the active phase of the LV flight is developed on the basis of the finiteelement discretization of the "propulsion – LV structure" self-oscillating syst...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | A mathematical model describing the nonlinear dynamical interaction of a launch vehicle (LV) and its marching liquid-propellant engine in the active phase of the LV flight is developed on the basis of the finiteelement discretization of the "propulsion – LV structure" self-oscillating system using three-dimensional and onedimensional finite elements. An approach to the computation of the liquid-propellant launch vehicle selfoscillation parameters self-oscillations of the liquid launch vehicle under POGO instability is developed. |
