This page discusses the details of the "Segmented" Grain geometry in the Rocket Motor Simulation Module.

A close-up of the Segmented grain geometry is shown in the following figure.

The following dimensions required for input are shown:

• DO is the exterior diameter of the rocket motor grain.
• D1 is the interior diameter of the rocket motor grain.
• X0 is the width of the slot in the rocket motor grain.
