Structures Sybsystem Progress Report 09/22/95 - A&M

This week we have spent on developing requirements and assumptions for integration with other systems. Our objective on volume is to provide as much as possible within the constraints of the Delta II rocket and divide the space up among the various subsystems. Our next objective is to come up with three conceptual designs for the structures system.
