Basic Overview of Model Rockets
Model rockets are an excellent way to explore the world of aerospace engineering on a budget. With just a few materials, some careful planning and construction, and a bit of patience, you can send your model rocket into the sky in no time!
Generally, model rockets are made out of lightweight materials like balsa wood and cardboard and use rocket motors to propel them into the air. Depending on the size of the rocket, these motors can come in different sizes and strengths — from low-power, plug-and-play starter packs to massive, high-powered motors that require special training to use.
Depending on the type of model rocket you’re building, you may also need a launch pad or tower, additional model rocket supplies such as glue and sanding materials, and a recovery system for your rocket. Most model rockets have built-in recovery systems that, once the rocket is launched, gently deploy a parachute that allows the rocket to drift down to Earth.
Of course, before you can do any of this, you’ll need to understand the basics of rocket science, including how rockets work and how to plan the right flight path. With the right information and some practice, you’ll soon be sending your own model rockets into the sky!

The launch lug is a small cylindrical post attached to the body, which holds the rocket onto the launch rod during ignition. The fin can is located near the bottom of the vehicle and houses the fins which are responsible for stabilizing the rocket during flight.
Rocket Engine
The core component of a model rocket is the engine. This component is responsible for providing the thrust required to initiate the flight. The engine is typically a solid-fuel booster containing thrust curves and delay times written on the packaging. A designated engine number, such as A8-4, will tell you what type and power of engine is ideal for the launch.
Ignite and Eject System
The ignite and eject system consists of the igniter and the ejection charge. The igniter is a small electrical component which conducts current from the launch controller to ignite the engine. The ejection charge is typically a small black powder charge which is used to deploy the parachute when the rocket reaches a safe altitude.
Recovery System
A recovery system is one of the most important parts of a model rocket. This component is responsible for slowing the rocket down after ignition and returning it back to the ground safely. The system typically consists of a parachute or a streamer, which must be deployed at a certain altitude. This component must also be robust enough to handle the forces generated by the rocket during its descent.
As you can see, there are many components of a model rocket which are all important for a safe, successful launch. Each component plays a vital role in providing the best experience possible for model rocket enthusiasts.
Assembling a Model Rocket
