Overview:

The booster case is what surrounds the actual liner and solid fuel, and can be thought of as the foundation for the motor. Its purpose is to hold the hot gasses from the fuel's combustion without bursting or melting, and to serve as a shell for other components to attach to. It consists of a single aluminum tube with holes for bolts.
