Sears–Haack body (cross sectional area)

Description

The Sears–Haack body is the shape with the lowest theoretical wave drag in supersonic flow, for a given body length and given volume.The mathematical derivation assumes small-disturbance (linearized) supersonic flow, which is governed by the Prandtl-Glauert equation. The cross sectional area of a Sears–Haack Body is related to the length and the volume of the body and the ratio of the distance from the nose to the whole body length (always between 0 and 1).
