| Abstract: |
The main objective of this project was the construction of a rocket motor using Hydroxyl-terminated Polybutadiene (HTPB) as fuel. The motor was intended for use in a hybrid rocket which was being designed and constructed as part of the Aeronautical Research for Engineering Studentsi (ARES) project, a group effort by members of Brigham Young University’s engineering department. The project involved design and materials testing in order to find the optimal fuel-to-cure ratio for the motor. Additionally, the project included the construction of igniters. These igniters were designed to burn for 10 seconds, long enough to ignite the HTPB prior to the release of the oxidizer for launch. As a result of the project, we were able to find the proper mix ratios for the motor as well as build the igniters, and these successes led directly to the construction of a complete hybrid rocket motor for the ARES project. |
