Solid Rocket Motor Cutaway and Grain

Rocket Propulsion is related to nozzle shape and the solid fuel inside its motor. This project consists of a cutaway view of a solid rocket motor and its main components - the motor case, insulation, ignitor, and the solid rocket fuel, called "grain," that fits inside. The pattern of the grain influences the behavior of the rocket as the fuel is burned. I have modeled seven types of grain in this project.

These cross sections of motors and fuel allow for exploration of the physics concepts related to thrust and momentum as well as geometric concepts like surface area, volume, and scale. These models offer a good starting point for any #ScienceProject or #EngineeringProject that relates to rocketry. Teachers can also use this project to add a real-life application of #Math and #MathProjects through an exploration of surface area and reading graphs.
