The hydrocarbon fuel used was the petroleum derived RJ-1J (RamJet 1J) with a density of 851 kg/m3 at 25 C. Beryllium, boron, aluminum and magnesium were selected as the additive metals to the LO2/HC propellant to improve the specific impulse and increase bulk density of the propellant. The results indicate that only beryllium, among the four metals, could improve the specific impulse. The effect of the propellant density was evaluated in rho X I(sub sp) (bulk density X specific impulse). Enhancement of performance with aluminum was equal to beryllium at a metal weight fraction of 50 percent. At 50 percent metal addition, the performance was improved about 14 percent compared with no metal addition.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
