Analysis of Possible Stratagems for Enhancing the EOM Power of RTGs for the CRAF Mission

PDF Version Also Available for Download.

Description

Paper presented at the 26th IECEC in Boston, MA August 4-9, 1991. This paper describes the various stratagems investigated and discusses their drawbacks and their effectiveness. The analytical results indicated that a combination of relatively modest RTG modifications that could be implemented in time for the mission could come very close to meeting the CRAF power demand goals specified by JPL. However, since even with the modifications the two RTGs did not provide sufficient margin for possible further growth in power demand, the JPL project team ultimately decided to use 3 RTGs for the CRAF mission also. This had the ... continued below

Description

Paper presented at the 26th IECEC in Boston, MA August 4-9, 1991. This paper describes the various stratagems investigated and discusses their drawbacks and their effectiveness. The analytical results indicated that a combination of relatively modest RTG modifications that could be implemented in time for the mission could come very close to meeting the CRAF power demand goals specified by JPL. However, since even with the modifications the two RTGs did not provide sufficient margin for possible further growth in power demand, the JPL project team ultimately decided to use 3 RTGs for the CRAF mission also. This had the decisive advantage of eliminating the need for load switching to reduce the power demand peaks. The purpose of this paper is to document the various power enhancement schemes analyzed and their computed effectiveness, for possible future applications. There are three copies in the file.
