Amateur Rocketry Society Of America

This 230 page book is illustrated with photographs and drawings covering every aspect of amateur rocketry. Written by a rocket propulsion engineer, John Wickman, with 30 years of professional experience in solid, liquid and exotic propulsion systems.

Anyone can start making their own motors and rockets with this book, even if you never made a rocket or rocket motor in your life. You don't need a college degree in chemistry or engineering to be successful with this bookset. Even if you know absolutely nothing about making rockets and rocket motors, all the information you need is in the book and video

But, the book is not just written for the novice. If you are designing motors based on a Kn spreadsheet, it is time to move up and start designing your motors for the precise thrust-time curve you want. If you are designing motors based on Kn and just increase Kn until you get a motor failure to find out the limit, you need this bookset. We will show you how to calculate the limits of your motor case and design a solid rocket motor that does not exceed those limits.

What makes this book package unique is the software and video that come with it. While the book is fully illustrated with photographs and drawings, there are some things such as mixing and casting propellant, making nozzles, folding parachutes and assembling rocket motors that are best shown by watching someone do it. In our included video or Mpeg format computer video, you will see someone do all of these things and lots more. It is like having a personal instructor in your house showing you how to do it. The DVD and Mpeg format computer video disks presents each of the sections from a menu (one page of the DVD menu shown at left) so you can watch just one section or the whole video.

Of course, if you want a real instructor rather than a video, you can always sign up for our "hands on" motor design class that includes the complete bookset. The "How To Make Amateur Rockets" book is also used as the textbook in the Introduction To Rocketry course (ES-1100) taught at Casper College. Click here for more information on the ES-1100 course. The bookset is being used by high school rocket groups like the one in Glasco, Kansas shown on the right getting ready to launch their scratch built rocket and rocket motor.

What makes modern amateur rocketry so different from the days of "October Sky" in the 1950's and 60's is the personal computer. Today, amateurs can test their rocket and rocket motor designs on their personal computers to see if the designs will work before a single part is built. CP Technologies was one of the first company to develop and bundle rocketry software together for amateur rocketry. Unlike software offered by other companies, our software has been extensively tested in the amateur and professional environment. It has been used to successfully design small rockets like those used in beginning Rocket Camp classes (left) and large rockets such as the SHARP S1 sounding rocket developed under NASA contract (right). The software bundled with the bookset will help you formulate solid, hybrid and liquid propellants, design solid rocket motors and rockets plus give you their performance in flight.

You can be saving over $50 on J class reloads by making your own motor or reload and save $100's on larger impulse reloads and motors. Don't fall for the myth that you don't save money making your own motors and reloads. Click here for an actual cost analysis on a 54mm Aerotech J90W reload.

With this bookset, you will not have to pay a hundred dollars or more for a rocket kit. After all, what are you really buying with that rocket kit? You are paying for the time someone took to design that rocket. Plastic nosecones and cardboard tubes don't cost a hundred dollars or more. With our "How To Make Amateur Rockets" bookset, you will be able to design your own stable rockets. Tired of showing up to launches with the same rocket as everyone else with only a different paint job? Break Free From The Pack!! Start designing the rockets you want to fly and save money, too!

Rocket Motor Design Classes Available!! - CP Technologies is offers a rocket motor design class bundled with our popular "How To Make Amateur Rockets" bookset. The class teaches students how to design and build their your own solid rocket motors. The instructor is John Wickman, a professional aerospace engineer and internationally known in the field of rocket propulsion. This class has been attended over the years by amateur rocketeers as well as professional aerospace engineers.

A highlight of the course is when students press the firing button on the control panel to test their rocket motor. It is not an ordinary firing button or control panel. It is the original firing button and control panel used by Aerojet, once called the "General Motors of Rocketry" by Time magazine. From this historic control panel was test fired solid rocket motors powering Polaris, Minuteman and MX missiles including tactical missiles such as Sidewinder, Maverick, Harpoon and many others. Students and their rocket motors will merge with solid rocket history as they press the firing button.
