Main Definitions
This is just going to be a garble of information
- nose cone
- self explanatory, the pointy thing in front of the rocket
- payload bay
- this stores what you want to carry and is generally made up of a shorter body tube, tube coupler, a bulkhead which closes the bottom of the coupler, and an eyebolt for the parachute
- airframe
- another name for the main body tube (this is the longer tube)
- motor mount tube
- these are smaller diameter tubes which sits in the center of your body tubes and holds your motor
Payload
The payload bay was kind of confusing, but it generally is like this, from top top to bottom
- nose cone: you know this
- payload body tube: just a shorter tube, same diameter as airframe
- payload: can be anything, like an electronics bay or an egg even
- tube coupler: a short tube with a diameter slightly smaller than the airframe
- bulkhead: closes the bottom of the coupler
The purpose of the tube coupler is to connect the payload tube to the airframe tube.
More Definitions
Now we get to auxillary smaller parts of the rockets
- motor retainer
- anything which keeps the motor from falling out, search online or take a look at LOC's Aero Pack
- centering rings
- these are circular wood (or any material) donut-shaped which center the motor mount tube within the body tube
- fins
- you probably don't need a definition for this
- launch lug
- basically a rod like attachment to your rocket to allow it to be launched from a launch rod
- rail buttons
- similar to launch lug, these are small buttons which allows your rocket to be launched from a rail
- parachute
- the thing that saves your rocket from a gruesome fate of falling to its demise
- nylon shock cord
- attaches between the eyebolt of the bulkhead to the eyebolt on the topmost centering ring of your rocket, the parachute is also attached to this
- recovery blanket
- a small sheet of fabric to protect the parachute and shock cord from the ejection charge
- shock cord sleeve
- protects the shock cord from the ejection charge (optional but recommended)
- quick links
- connects the shock cord to the eyebolts
The ejection charge is a force directly towards the nose cone emitted by the motor for the purpose of popping the nose cone portions off and deploying the parachute.
