Low-Erosion Nozzle Materials For Long-Duration Hybrid Rocket Burns, Russell S. Babb
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Hybrid rocket systems, which employ a solid fuel grain and a liquid oxidizer, are a low-cost and environmentally friendly alternative to traditional rocket systems. However, hybrid rockets suffer from an increased nozzle throat erosion rate, which impacts motor performance and reliability. To address this issue several materials and low-erosion nozzle configurations were tested. The results of the testing campaign produced a nozzle that reduce the throat erosion rate five-fold.
