I found a formula on a Parabolic Nosecone -> V= Pi * d² * h : 8 (and additionally :1000 for mm³ in cm³ for g/cm³ calculation) The descripion notes that diffrent shapes of parabolic nosecones exist. The question is , for what version is the given formula? Quote: " K' = 0 for a cone , K' = 0.5 for a 1/2 parabola , K' = 0.75 for a 3/4 parabola , K' = 1 for a full parabola , For the case of the full Parabola (K'=1) the shape is tangent to the body at its base, and the base is on the axis of the parabola. Values of K' less than one result in a slimmer shape, whose appearance is similar to that of the secant ogive. The shape is no longer tangent at the base, and the base is parallel to, but offset from, the axis of the parabola." = is the given formula for a Tangent Ogive/ or another shape? + Is the "tangent" a true Tangent Ogive or just as quoted "tangent at its base" The reason for this question is that the formula results in a rather small volume, so a diffrent shape seems possible, (because a diffrent angle towards the base where the diameter is the largest, would result in high volume loss). + does anyone knows the formula for a truly tangent nosecone? Thanks for any answers.
