NRP 1358, System Engineering "Toolbox" for Design Oriented Engineers
NASA REFERENCE PUBLICATION - NRP 1358, System Engineering "Toolbox" for Design Oriented Engineers. The purpose of this system engineering toolbox is to provide tools and methodologies available to the design-oriented systems engineer. A tool, as used herein, is defined as a set of procedures to accomplish a specific function. A methodology is defined as a collection of tools, rules, and postulates to accomplish a purpose. A thorough literature search was performed to identify the prevalent tools and methodologies. For each concept addressed in the toolbox, the following information is provided: (1) description, (2) application, (3) procedures, (4) example, if practical, (5) advantages, (6) limitations, and (7) bibliography and/or references.

NRP 1368, MSFC ELECTROMAGNETIC COMPATIBILITY DESIGN AND INTERFERENCE CONTROL (MEDIC) HDBK
NRP 1368 (CDDF Final Report, Project No. 93-15), MSFC ELECTROMAGNETIC COMPATIBILITY DESIGN AND INTERFERENCE CONTROL (MEDIC) HDBK. Marshall Space Flight Center Electromagnetic Compatibility Design and Interference Control (MEDIC) Handbook is intended to be used primarily by those organizations involved in the electrical design of payload equipment and subsystems. The purpose of this Handbook is to provide practical and helpful information in the design of electrical equipment for electromagnetic compatibility (EMC). Chapter 1 of this Handbook is an introduction to electromagnetic compatibility (EMC). It includes definitions of terms and units as well as basic electromagnetic interference (EMI) interactions. Chapter 2 is an overview of typical NASA EMI test requirements and associated test setups. It is not intended to be a “how to” of EMI testing, but rather a general overview so that the electrical designer knows what to expect during testing. Chapter 3 contains general design techniques to minimize the risk of EMI and deals with EMI suppression at the board and equipment interface levels. Chapter 4 gives specific EMI test compliance design techniques and retrofit fixes for noncompliant equipment. These techniques and retrofit fixes are specific to a given MSFC EMI test. Chapter 5 explains how to perform special tests useful in the design process or instances of specification noncompliances. Appendix A lists the acronyms and abbreviations used in this document. The MEDIC Handbook was prepared at the Marshall Space Flight Center (MSFC) by the Electromagnetics and Environments Branch (EL54). Funding for developmental testing was provided by the MSFC Center Director’s Discretionary Fund (CDDF), Project No. 93-15.

NRP RP-1403, FORCE LIMITED VIBRATION TESTING MONOGRAPH
NASA REFERENCE PUBLICATION RP-1403, FORCE LIMITED VIBRATION TESTING MONOGRAPH. The practice of limiting the shaker force in vibration tests was instigated at the NASA Jet Propulsion Laboratory (JPL) in 1990 after the mechanical failure of an aerospace component during a vibration test. Now force limiting is used in almost every major vibration test at JPL and in many vibration tests at NASA Goddard Space Flight Center (GSFC) and at many aerospace contractors. The basic ideas behind force limiting have been in the literature for several decades, but the piezo-electric force transducers necessary to conveniently implement force limiting have been available only in the last decade. In 1993, funding was obtained from the NASA headquarters Office of Chief Engineer to develop and document the technology needed to establish force limited vibration testing as a standard approach available to all NASA centers and aerospace contractors. This monograph is the final report on that effort and discusses the history, theory, and applications of the method in some detail. To facilitate the application of the method, a more concise description of the key aspects of the approach is presented in a complementary guidelines document, which is available separately and is also contained herein as Appendix C
