Abstract
This work aims to compute stability derivatives in the Newtonian limit in pitch when the Mach number tends to infinity. In such conditions, these stability derivatives depend on the Ogive's shape and not the Mach number. Generally, the Mach number independence principle becomes effective from M = 10 and above. The Ogive nose is obtained through a circular arc on the cone surface. Accordingly, the following arc slopes are considered lambda = 5, 10, 15, -5, -10, and -15. It is found that the stability derivatives decrease due to the growth in lambda from 5 to 15 and vice versa. For lambda = 5 and 10, the damping derivative declines with an increase in lambda from 5 to 10. Yet, for the damping derivatives, the minimum location remains at a pivot position, h = 0.75 for large values of lambda. Hence, when lambda = -15, the damping derivatives are independent of the cone angles for most pivot positions except in the early twenty percent of the leading edge.
