| Outline of Final Research Achievements |
To achieve the practical use of nonhazardous small rockets, We have developed CAMUI type hybrid rockets. CAMUI rockets are free from explosives and liquid fuels, resulting in lower costs for safety management. This research clarifies scale effects on fuel regression characteristics mainly by static firing tests. The firing tests covers Reynolds number range from a few thousands to over a half million. A numerical simulation clarified the mechanism responsible for the effect. By using these results, we can obtain basic design data by static firing tests of a subscale motor. Finally, we developed a 15 kN thrust class motor. Firing tests by this motor show good results, verifying the method developed in this research.
