The Only Book That Fully Explains How To Make Rockets That Was Written For Both The Novice & Experienced Amateur
An Incredible Book/Software/Video Set Value For All Composite Solid Rocket Propellants!
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.
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, 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 video 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
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.
Look At The Software Included With The Book!
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.

THERM* - Version 3 - Calculates the thermal ablation and temperatures of nozzles, exit cones, bulkheads and chambers. It also calculates temperatures within a rocket body at various locations from the nose due to aerodynamic heating.
CG-CALC* - Determines the center of gravity and lift off weight of your rocket before you build it.
STRESS * - Spreadsheet analysis on your chamber, nozzle and bulkhead.
HTBOUND * - Spreadsheet calculation of key thermal input parameters used by THERM.
BURNRATE * - Determines the coefficient and exponent for your propellant formulation based motor data or single strand burn tests.
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.

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
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.
