Amateur rocketry is a leisure-time activity in which partakers experiment with rockets, propellants, and propulsion among other basic space flight concepts. In essence, enthusiasts experiment with fuels, solid, and liquid propellant motors to make their own rockets. Unlike professionals, they pursue the activity as a hobby. Amateur rocketry encompasses physical sciences and mathematics in basic rocketry which may be useful for the development of hybrid motors and rockets.
To enjoy amateur rocketry as an educational hobby, the enthusiast must take an interest in rocket science and space flight technology. Amateur rocketry also involves aerodynamics and aeronautics which makes it highly enjoyable for people who are interested in these fields. To begin, several basic materials are needed to build an amateur rocket. Additionally, some these materials like motors can be developed by the amateur rocket enthusiast. Some of the common materials used for creating amateur rockets include plasticizers, motors, R45 binders, burn rate accelerators, EPDM rubbers, and certain chemicals necessary for propulsion. You will also need other accompanying tools and materials such as a test stand, a propellant mixer, and a launch controller. These materials can be found in chemical stores, hardware stores, toy shops, and even specialty amateur rocketry stores.
While the creation and development of amateur rockets can be fun, it’s also a dangerous activity with potential to turn fatal if safety precautions are not followed. Most of the propellants and propulsion equipment are made from flammable materials and chemicals so they can present some danger. At the same time, it’s noted that most accidents in amateur rocketry occur due to negligence and ignorance of basic safety rules. Some of these rules include the use of certified commercial-made rocket motors, lightweight rocket body parts, and electrical launch systems. It’s also important to launch the rocket outdoors, ensure the rocket does not weigh more than 1500 grams, use a launch countdown, and not launch at targets.
Amateur rocketry is an educational hobby in the sense that it involves a number of scientific topics and subjects. To be a good participant, you must have vast knowledge in various topics including mathematics, aerodynamics, thermodynamics, gas dynamics, and other basic physical sciences. Since amateur rocketry involves a lot of calculations, mathematics, especially calculus, plays a major role in the design and flight of rockets. The flight of rockets also involves the interaction of various forces, allowing participants to learn how the forces work. Amateur rocketry is also very important in the development of hybrid rockets because model rockets are often used for research and design in the more powerful professional rockets.
