An Integrated Design Methodology for Architecture Solutions to Shimmy Reduction Subsystems in All Electric Aircraft

Abstract

This article investigates the search for architecture solutions to a novel shimmy reduction subsystem in the nose wheel steering system (NWSS) of all-electric aircraft (AEA). Since the traditional trial-and-error and empirical methods are inefficient and infeasible in this study, respectively, a new methodology for system architecture design is needed. The integrated methodology combines the systems engineering engine method and V-model to explore the design space of the shimmy reduction subsystem, defines the parameters of the low-level product using general morphological analysis (GMA), eliminates incompatible alternatives through cross-consistency assessment (CCA), and, after morphological analysis, subjects the solutions that satisfy the optimal design set to a single-objective decision based on cost-effectiveness analysis (CEA). Furthermore, a product realization of the final selected design solution is presented, along with the implementation and verification processes. The methodology deals with the problem in the design of the shimmy reduction subsystem in AEA.
