Inner Components Basics
Internal components vary widely in how they can be used. And, sometimes a picture can explain things easier than a thousand words, so here is the rocket that will be used to identify different internal components and their most common use.

| Component | Function |

Inner Tubes: <<INSERTION POINT>> |
 |
Couplers: Couplers are generally thicker than other inner tubes so that they can strengthen the joint between the tubes that they are joining. Inner tubes, with lids, are also used to make avionics bays to protect altimeters and other electronic components |

Centering Rings: <<INSERTION POINT>> |
 |
Bulkheads: Bulkheads are a flat disk, like a plate. Most frequently bulkheads are glued inside of another tube to either prevent ejection gasses from passing or mount recovery attachments to. Bulkheads of two different diameters are also commonly glued together to make inset lids for avionics bays. |

Engine Blocks:The purpose for an engine block is reflected in its name. The engine block is a short, thick, smaller diameter inner tube that is glued inside the forward end of the inner tube being used to hold the engine or motor, and, when the engine is pushed into the inner tube, the engine block physically blocks its path, preventing it from going in any further. Tape is usually wrapped around the engine before inserting to bind it enough that the ejection charge doesn't blow it out, but not so much that it can't be removed after the flight. |
