Title: Recent development of liquid hydrocarbon propellants Source: Proceedings of the First ISAS Space Energy Symposium, Institute of Space & Astronautical Science, 4-6-1 Komaba, Meguro-ku, Tokyo 153, Japan, Jan. 28-29, 1982. (Paper No. V-l) Authors: Iwama, Akira < Institute of Space & Astronaut i cal Science> Date: 01-28-82 Classification: u Keywords: transportation Abstract: As to the liquid propellants for the first stage booster of multistage rockets and air breathing jet propulsion vehicles, emphasis is placed on the density specific impulse. Particular 1y, hydrocarbon fuels with high density is desirable for the cruising missiles to be obliged to fly at very low altitude. ATTACHMENT : This brief review describes the possibility of hydrocarbon fuels replacible for RJ-1, whose supply is unstable since the most vehicles loaded with RJ-1 have retired, and recently spotlighted synthetic fuels for cruising mi ssi1es. Title: The applicabi1ity of hydrocarbon fuels (HC) for advanced booster vehicles Source: Proceedings of the First ISAS Space Energy Symposium, Institute of Space & Astronautical Science, 4-6-1 Komaba, Meguro-ku, Tokyo 153, Japan, Jan. 28-29, 1982. (Paper No. V-2) Authors: Nagashima, Ryuichi; Izumita, Masayuki; <National Space Development Agency of Japan (NASDA) Date: 01-28-82 Classification: u Keywords: transportation Abstract: The applicability of high impulse, low density cryogenic hydrocarbon fuels (especially methane and propane) for advanced booster vehicles was i nvestigated. This study was performed in accordance with three steps as follows... ATTACHMENT : (1) Task I is to define characteristics of candidate fuels. (2) Task II is the trade off study based on total vehicle system desi gn. (3) Task III is to obtain the maximum chamber pressure which is determined from both the hydrocarbon regenerative cooling limits and the operating limits. The result through Task I - Task III showed that methane (CH ) or propane 4 (C H ) was recommended as the most effective advanced booster propellant. 3 8
