Witryna28 cze 2024 · For a deeper understanding of the physical phenomenology of shock-induced panel flutter, a theoretical model for analyzing aeroelastic stability of flexible panels subjected to an oblique shock has been developed. The von Kármán large deflection plate theory is used to account for the geometrical nonlinearity, and local … WitrynaThus, a local piston theory approach provides a reasonable model for the surface pressure.17 Two different methods are used to compute the required local flow properties. The theoretical approach uses shock-expansion theory. This is denoted as the shock-expansion-piston theory (SEP) model. A refined approach is to use …

WitrynaA flow field modified local piston theory, which is applied to the integrated analysis on static/dynamic aeroelastic behaviors of curved panels, is proposed in this paper. The local flow field parameters used in the modification are obtained by CFD technique which has the advantage to simulate the steady flow field accurately. This flow field modified … Local piston theory. The classical piston theory is a powerful aerodynamic tool. From the use of the momentum equation and the assumption of isentropic perturbations, one obtains the following basic piston theory formula for the surface pressure: = (+) ...
