Predicting Reliability and Maintainability Factors for Aircraft Subsystems During the Conceptual Phase of Aircraft Decision.
Abstract
In the past thirty years, reliability and maintainability have become a growing part of system design. This is due in part to the knowledge imparted by the problems incurred on the first generation of complex jet aircraft. Many lessons were learned from the first generation aircraft that are now incorporated in modern aircraft design. Today's environment of budget cuts and constraints also requires reliability to be built into an aircraft design in the conceptual stage of design. For space systems, it is imperative that reliability be built into the design in the very early stages and considered throughout the design process. This case study used aircraft design and performance characteristics (independent variables) and reliability and maintainability parameters (dependent variables) in multiple regression analysis to develop parametric equations that predict reliability and maintainability factors for aircraft subsystems. The subsystems analyzed were landing gear and engines.
