(Paper No. IV-13) Authors: Uji, Masaru; Tezuka, Hitoshi; <Nissan Motor Co., Ltd.> and Saito, Katsutoshi; <National Space Development Agency of Japan> Date: 12-13-82 Classification: u Keywords: alternative systems, space energy conversion conversi on Abstract: A study has been carried out, in this paper, on a heat engine whose working gas is the vapor generated in a heat pipe, as a power generator used in space stations. The engine has the same heat cycle as that of Otto engine, but the available temperature difference is small. When this engine is used in ATTACHMENT : space stations, the high temperature of a radiator and the low temperature in space are expected to be the high and low temperature sources respectively. Because of the small temperature difference, the engine efficiency is not great.

(Paper No. 1-4) Authors: Woodcock, Gordon R.; Silverman, Sidney; <The Boeing Co.> Date: 02-22-82 Classification: u Keywords: onboard power storage and distribution, solar cells, space energy conversi on Abstract: Manned space stations now in preliminary design will exhibit power needs from 25 to 150 kW. Studies have examined solar cel 1/battery, solar cell/ regenerative fuel cell, and nuclear systems. This paper will summarize the power requirements, the tradeoff between batteries and regenerative fuel cells, ATTACHMENT : including how the electric power system can be integrated with other functions, and nuclear concepts. The influence of mission applications on selection of the power system will be discussed, including LEO and high Earth orbit civil missions and potential military missions.

(Paper No. 1-5) Authors: Caveny, Leonard H.; <Aerospace Sciences Directorate, Air Force Office of Scientific Research, Bolling AFB, Washington DO Date: 02-22-82 01assification: u Keywords: transportation Abstract: Propulsion systems are being considered in two categories: conventional (chemical) and nonconventional (e.g. beamed energy and electric). If the investments are made, the Air Force can be assured of having significant 1y improved chemical propulsion systems available by the end of the
