Saturday is the final day of this course. On this day, we all get to see or rocket motors fired from John Wickman’s test facility. So it is time to prep our motors and finish Rocket Motor Design Class – Static Test Day.
The motor was ready to go on Saturday morning. The only thing left to do was to insert the igniter I created yesterday into the motor and secure it with tape. John explained some gotchas and failures in ignitions in his past experience.
The motor was mounted to a stand in the test building. A pressure transducer was attached to the fitting I had inserted into the cap of the motor. This transducer will measure the pressure of the motor chamber during the static test.
I learned a lot in this class. Not only about making amateur rocket motors, but many ideas about proper engineering and testing practices. John Wickman’s workshop is a museum of rocket history.
I recommend this course to anyone who is interested in rocketry and rocket propulsion. During some of the breaks, you also get a chance to watch some classic rocket failure and explosion videos. John Wickman has his own chapter in the history of the United State’s solid rocket motor program.
