Types of Model Rockets
Model rockets come in a variety of shapes and sizes, ranging from smaller toys to mid-size rockets used for competition. While all model rockets are powered by a rocket engine and are propelled into the air by the same basic principles of aerodynamics, there are some differences among the different types.
Ready-To-Fly Model Rockets
Ready-To-Fly (or "RTF”) model rockets are designed to be assembled by novices with no additional parts required. They may come with a pre-assembled body, motor, launch system, and recovery system. These rockets usually require no additional tools or advanced building techniques, making them great for people just starting out or those with little experience. One of the other great benefits of RTF model rockets is that they are relatively inexpensive compared to other types.
Toys and Educational Model Rockets
These smaller rockets are designed primarily for children and/or students to learn about flight and aerodynamics. They tend to have very simple designs, making them an ideal choice for beginners. Generally, these rockets are powered by small elastic bands, rather than a traditional rocket engine, so there is no need for extra fuel or an advanced launch system. Most come with a basic launch pad and recovery device, so they can be easily set up and launched outdoors.
Competition Model Rockets
Competition model rockets are larger and more complex than other types. Typically, these rockets will require advanced assembly, as well as expertise in engineering, airfoil or rocket body design, motors, and launching. As their name suggests, they are used in competitions and must meet safety standards outlined by the National Association of Rocketry (NAR).
High-Power Rockets
These model rockets require more complex construction and are designed for more experienced rocketeers. As their name implies, they use more powerful motors that can be used to create more spectacular shows. Unlike competition or RTF rockets, they tend to need more sophisticated launch systems and may require a higher degree of safety precautions.
Components of a Model Rocket
Building a model rocket is an exciting science project for all ages. Aspiring rocketeers must understand the components of their model rockets in order to properly assemble and launch their creations. This guide outlines and explains the basic parts that make up a model rocket.
Body
The body of the rocket is the bundle of tubes and panels that gives the rocket its physical shape. Different rockets may feature different designs, but most model rockets consist of a cylindrical tube, a nose cone, and long cylindrical fins.
Engine
The engine is what propels the rocket into the air at launch. Most model rocket engines are bi-propellant, featuring a low energy fuel and oxidizer combination. The exact composition of the fuel and oxidizer, as well as the engine design, depends on the manufacturer.
Launch System
Model rockets launched without assistance from outside tools are more difficult to get off the ground. Most model rocket enthusiasts utilize a launch system for assistance. This system consists of a launch pad, launch controller, launch rail, and igniter. All components must be securely connected to one another in order to safely fire the rocket engine.
Recovery
Recovery systems are essential for a model rocket, as they safely and securely return the rocket to the ground once it has fulfilled its mission. Most of these recovery systems feature a parachute, which deploys at a certain altitude, slowing the rocket's descent and cushioning its impact with the ground. Some recovery systems also feature shock absorbers or other protective designs.
Additional Components
Depending on the purpose of the model rocket, it may require additional components. For instance, a rocket carrying scientific devices may feature a wireless communication system that sends data to the ground station, or a drone-style model rocket may include a camera or other recording device.
With the right components, aspiring rocketeers can construct and launch their own safe and successful model rockets. Check out more of our guides for more information about model rockets and their parts.
