CP Technologies was the first company with a comprehensive book, video and software set explaining in detail how to make composite solid rocket propellant motors and amateur rockets. The purpose of the bookset was to help amateurs, with no prior knowledge of rockets and motors, to design, build and launch rockets successfully. While the bookset is comprehensive, you may still have questions, have problems, or need more information. This page is here for you to find the help you need and provide you with additional resources for you to be successful. If you can't find what you need here, you can email us at firstname.lastname@example.org.
We have provided a link to a web page with some propellant formulas you can use in your motors. It is important to note that your burn rate parameters may be different from those listed on the page. This is due to particle size and shape. It is best to make a simple motor and instrument it with a pressure transducer to measure chamber pressure. This will give you a check on the burn rate parameters. If they appear to be different from those on the web page, you will need to recharacterize the propellant for your chemicals. Particle size and shape vary greatly from suppliers and these changes can in some cases make major changes in the burn rate parameters.
Software installation instructions and user's manuals for the bookset software are included on the software CD. You can also download these instructions using the link below.
There are periodic corrections and updates to the "How To Make Amateur Rockets" book. Click on the link below for the latest updates and corrections.
Periodically, we post motor designs. You designs as starting points for your own motors. Click on the links below for motor and reload designs.
There is an entire chapter in the book devoted to static firing your rocket motor. However, we have provided additional information along with sources for instrumentation and data acquisition equipment that can be useful to you.
