The American Institute of Aeronautics and Astronautics (AIAA) holds a propulsion exposition every year. Part of the exposition are ancillary workshops on topics in the propulsion arena. One of these workshops was held at the Zucrow Laboratories on Purdue University’s Lafayette, Indiana campus. I attended this workshop with about 50 other scientists, industry professionals, students, and two hobbyists (one which was me). What follows are some of the highlights from the AIAA Rocket Testing Workshop that interested me as a rocket hobbyist and space enthusiast.Continue reading “AIAA Rocket Testing Workshop”
In the first article of this series, Return to Model Rocketry, I discussed some of the kits and kit manufacturers that exist today. However, a rocket without some way to propel it into the sky is just a cardboard, fiberglass, or carbon fiber tube. This article will talk about model rocketry propulsion in its various forms.Continue reading “Model Rocketry Propulsion”
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 agenda for Friday was mostly concentrated on finishing our rockets in preparation for the static firing on Saturday morning. The propellant had cured overnight and was ready for final motor construction. Let’s review what happened on Rocket Motor Design Class – Day Three.

Rocket Motor Design Class – Day Two started with a discussion of solid rocket motors. Interesting fact, one of the first useful American solid rocket motors was made in World War Two. It was used to assist U.S. Army Air Corps bombers in taking off from small Pacific islands as many of the runways were very short. The motor was made with ammonium perchlorate as the oxidizer and asphalt as the fuel.
I signed up for this course a few months ago and it started today. You can find out all the details at Design & Make Your Own Solid Rocket Motors. I flew into Denver yesterday, rented a car, and drove to Caspar, Wyoming to attend this class. After dodging a tornado, driving through a hail storm, and siting antelope; I arrived. So let’s start with the Rocket Motor Design Class – Day One.
