**Newtonian Lift and Drag of Blunt Cone Cylinder Bodies.**

by **J. Pike.
AIAA Journal, Vol. 10, No. 2, pp. 176-180, February 1972**

**Summary.**

Newtonian theory is used to derive the lift and drag of a class of axisymmetric bodies representative of rocket or re-entry shapes.
The expressions are valid for any orientation of the bodies, and they are used to obtain the maximum lift to drag ratio for a constant friction drag.
They are also used to optimise the nose shape for a given thickness ratio.
It is found that there is a unique blunted body, which at any incidence less than about 30 degrees, has both maximum lift ad minimum drag.

**Comment.**

This early paper demonstates the way in which Newton's Impact theory allows the derivation of analytic expressions for the aerodynamic forces on certain types of body shape.
