Sears–Haack body (volume)
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 volume of the body can be calculated by the radius at its maximum (occurs at center of the shape) and its length.
