Some Aspects of Japanese Energy-Conversion Research and Development,
Abstract
The Japanese effort in chemical propulsion has shown a marked technological advance in capabilities in the 10 years since the prior visit of the author. However, in spite of this growth, there was little evidence of marked new contributions by the Japanese. For the most part, excellent application has been made of techology developed, primarily in the United States. Continued growth in this field can be anticipated, with increased Japanese capability in satellites orbiting with larger payloads. In addition a shift from solid-propellent to liquid-propellant rockets may take place; however this is not anticipated within less than 5 years except by licensing from U.S. corporations of purchase of high-thrust liquid-propellant rocket motors. The same situation generally prevails in the fuel-cell and battery activities visited. In this field the close ties to U.S. development, as in the case of solid-propellant rocketry, were apparent. It will be especially interesting to observe the future fuel-cell developments and whether fuel cells will be reduced to submarine practice. (Author)
