A pintle injector is one of the most promising candidate for the propellant injection system of LRE with deep-throttling capability due to the simple structure and the high combustion stability. However, effects of various design parameters of a pintle injector on combustion characteristics are not clarified yet. Combustion experiments of an ethanol/liquid oxygen rocket engine combustor with a planar pintle injector are conducted to investigate the effects of the injection configurations on combustion characteristics. The chamber pressure Pc and mass flow ratio of oxidizer and fuel O/F varies from 0.3 MPa to 0.4 MPa and from 1.0 to 2.2, respectively. Back-lit images of spray structures are observed with high speed imaging techniques. Characteristic exhaust velocity (C (exp *)) efficiency increases with the increase in O/F with fuel-centered configuration, while the opposite tendency is observed with oxidizer-centered configuration. The linear relationship between total momentum ratio (TMR) and C (exp *) efficiency is found for both injection configurations. The coefficient of variation (CoV), which is an indicator of combustion stability, increases with the increase in O/F for both injection configurations.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
