The main goal of this paper is to analyze the flutter boundary and dynamic load of a supersonic fin. Reduced order mode (ROM) based on Volterra Series is presented to calculate the flutter boundary, and CFD/CSD coupling is used to compute the transient aerodynamic load. The Volterra-based ROM is obtained using the derivative of unsteady aerodynamic step-response, and the infinite plate spline is used...
The main objective of this paper is to numerically investigate the effects of a divert jet on the overall aerodynamic performance of a generic interceptor missile operating at moderate angle attack. A generic missile interceptor configuration consisting of a long, slender body containing tail fins is simulated in this study. Firstly, K-epsiv, K-omega and S-A turbulent model are evaluated in simulating...
Presented is an investigation into Advection Upstream Splitting Method (AUSM) family schemes. A newly improved version of the AUSM scheme, called AUSMPW+, was developed to increase the accuracy and computational efficiency of AUSM scheme in capturing oblique shock without compromising robustness. With a new definition of the numerical speed of sound at a cell interface, the ability of capturing an...
