| Summary: | In this modern era of space flight dynamics, every nation wants to share its pride in developing one of the fastest
flights and making its defense aircraft the best. In designing the aircraft, wedges play a vital role in the optimization of the
aircraft. Non-planar wedge configurations promise a significant role in aerodynamic efficiency. Analytical expressions have been obtained for derivatives in stiffness for an oscillating non-planar wedge in hypersonic flow in the Newtonian limit in the present investigation. Results have been plotted for various Mach numbers and varied positions of the pivot using these equations. It is observed that the value of the stiffness derivative descends with added increment in the position of the pivot for different incidence angles and fixed slopes. The pattern is erratic for the lower angle of incidence, which is the variation of planform area and stalling of the flow. |
