1.0 INTRODUCTION

Martin Marietta will perform the Space Station Common Module Power Sys-tem Network Topology and Hardware Development program in full accord-ance with the request for proposal (RFP) with no exceptions taken tothe statement of work (SOW).

This study plan contains Martin Marietta's approach to performing theproposed program. Performance of the tasks described will assure sys-tematic development and evaluation of program results, and will providethe necessary management tools, visibility, and control techniques forperformance assessment.

The plan is submitted in accordance with the data requirements given inthe RFP and includes a comprehensive task logic flow diagram, time-phased manpower requirements, a program milestone schedule, and de-tailed descriptions of each program task.

The study plan, when approved by Marshall Space Flight Center (MSFC),will become the basic guideline document for this program and willserve as the primary program control document for the MSFC contractingofficer representative (COR) and the Martin Marietta program manager.Should changes result from progress reviews by the National Aeronauticsand Space Administration (NASA), the work plan will be updated to re-flect the new program baseline.

The overall objective of this program is to define and develop candi-date power system network topologies for the Space Station common mod-ule and to provide the necessary hardware for test and evaluation.

2.0 PROGRAM TASK FLOW

Our program task flow logic (Fig. A-l) provides fundamental insightinto our plan for total compliance with the SOW and indicates the rela-tionship between all tasks and subtasks, including requirements. Eachmajor program task is shown as a boldly outlined box. Each box showsthe sequence of subtask activities and the interrelationships withother tasks, subtasks, and other related activities. The flow alsoshows required MSFC COR approvals. The task number and work breakdownstructure (WBS) reference are shown in each block.

The project inputs—which include the RFP, NASA Space Station design,and analysis data—will feed program Task I. Task I will include re-quirements definition, network concept development and selection, andthe detailed evaluation of selected concepts. This task will alsobenefit from the ongoing Martin Marietta Independent Research and De-velopment Project D-47S, "Space Station Subsystem Integration," and theplanned NASA/MSFC Common Module Power Management Automation Study. OurIR&D project will aid the requirements definition and provide supple-mentary information on control system options and a power quality as-sessment for the various input power types. This will enhance the con-cept definition and selection process. Interaction with the MSFCCommon Module Power Management Automation Study will aid in the defini-tion of sensor and power control devices and their interfaces. Thehardware defined in Task I will be assessed for technology readiness inTask II. Our ongoing Martin Marietta IR&D Project D-30D, "AdvancedPower System Technology," will benefit both this task and Task III.That project includes the testing and evaluation of solid-state andelectromechanical switchgear and the development and test of high-frequency ac power coverters, both ac-ac and ac-dc types. Task IIIwill prepare and implement advanced development plans and procure thehardware necessary for verification and test at MSFC. In Task IV, wewill develop recommendations for system testing, prepare test proce-dures and other test documentation, install hardware at MSFC, and per-form initial system testing. Task V will include contract reportingtasks.
