Reliability Advancement for Electronic Engine Controllers. Volume 2. Guide to Development of High Reliability Electronic Engine Controllers
Abstract
Based upon the work done in evolving the preliminary design of 'Volume I: Final Report' this document has been prepared to serve as a guide for developers of future high reliability gas turbine engine controls. After defining the control modes and requirements for a Variable Cycle Engine various options are considered regarding system configuration, redundancy management, system simplification, and fault handling. Principles for optimizing component mix and circuit design, along with possibilities for alternative implementations are presented. To successfully control the environmental exposure of the EEC, aspects of thorough packaging design are described. The entire Reliability Program of an organization plays a key role in the development of high reliability controls. Major elements of a successful program are discussed. Particular emphasis is placed upon implementation of reliability tests and screens designed to enhance electronic hardware reliability. Reliability mathematical modeling techniques are utilized to evaluate control options during system trade studies and to predict and enhance reliability growth during the design and development program and the production program.
