Descrição: dc.descriptionA diaphragm has been used to enhance fuel regression rate and combustion efficiency in hybrid rockets. On the other hand, it has been observed that significant pressure oscillations occurred. In this paper, main factor on the excitation of the instability was studied. Lab-scale firing tests considering the various experimental conditions, such as the diaphragm location and diameter, were conducted, and combustion visualization tests were performed to confirm the instability mechanism. The excitation source of the pressure oscillations was the edge-tone instability. Finally, a new grain which had high regression rate and also was stable combustion was proposed.-
