Effect of sweep angle and a half sine wave on roll damping derivative of a Delta Wing

This paper presents the effect of sweep angle on a roll of damping derivative of a delta wing with half-sine wave for an attached shock case in supersonic/hypersonic flow has been studied analytically. The Ghosh Strip theory is replicated. By combining this with the similitude at high-speed flows l...
