Regression Rate Study in HTPB/GOX Hybrid Rocket Motors.

摘要

The theoretical and experimenIal studies on hybrid rocket motor combustion research are briefly reviewed and the need for a clear understanding of hybrid rocket fuel regression rate mechanism is brought out. A test facility established at the Indian Institute of Technology, Madras, for hybrid rocket motor research study is described.The results of an experimental study on hydroxyl terminated polybutadiene and gaseous oxygen hybrid rocket motor are presented. Fuel grains with ammonium perchlorate "additive" have shownenhanced oxidizermass flux dependence. Smallergrains have higher regression rates than those of the larger ones.
