| Rocket Motor Grain Geometry |
The user must next select an appropriate grain geometry for the rocket motor energetic. The selection of grain geometry is based on desired acceleration, burn time, and other considerations. The figure below shows pictures of the Grain Geometry options for the Rocket Motor Simulation Module.
At the upper left is the "Star" Grain Geometry.
At the upper right is the "Wagon Wheel" Grain Geometry
At the lower left is the "Slot" Grain Geometry
At the lower right is the "Segmented" Grain Geometry
For the purposed of this tutorial, we will be using the Star grain geometry, which will be discussed in detail in the following pages of the tutorial. Details on the other grain types are available at the end of the tutorial.
