Analytical estimation of stability derivatives of wing with curved leading edges at hypersonic mach number

This paper focusses attention on the influence of prominent curved ends to restraining deprived owing to the transverse frequency for the numerous amplitude, flow rebound perspective δ, hinge location, and the inertia. In the current learning by the consequence of expansion fan on the expansion side (i.e., Leeward surface) are neglected. Outcomes of the demonstration are that with the increase of the amplitude of the half-sine wave, there is a progressive increase in the-hampering spinoffs from k = 0, advanced to the TE, it declines up to the whereabouts of the normal force location and just opposite trend. At the place of k = 0.4, while we deliberate the permanence spinoffs in curbing for the pitch q, there is a reduction in the mathematical tenets of the derivatives, and this trend continues till k = 1 towards the trailing edge. This upsurge is not linear and not like for position near the foremost edges. The change in the enormousness of the inhibiting results because of the deviations in the Mach (M), flow deflection angle δ, and the amplitude of the sine wave persisted in the identical kind
