Abstract

Abstract This paper describes a new operating mode for chemically fueled turbine type space power units. High temperature gases are admitted to the turbine section for a brief period. The turbine and alternator system then coasts for a much longer period with minor loss in speed because of the large angular momentum. This operating mode can result in a high efficiency turbine utilizing gas temperatures in excess of 3500°F with a wide power range and a highly simplified control. Such a system has been laboratory tested successfully. The combination of low fixed weight, relatively low propellant consumption and use of storable propellants gives this system an advantage for space power requirements of high output and short duration. It can be used where power levels of 1 to 100 KW are required for. 5 to 50 hours.
