The Research on Redundant Design in Civil Aircraft Design

Abstract

This article explores the redundant design in the design of civil aircraft. It’s based on the meaning of giving redundancy beyond the basic needs to the parts or the products by redundant design. And this article also conducts targeted research on several typical redundant design methods such as redundant design in sketch, redundant design steps in part, integrated design of parts, redundant parts in assembly and redundant assembly of the civil aircraft. The redundant design formulas corresponding to different design methods are obtained by analyzing specific design examples. It is found in the research that redundant designs and components are also effective ways to optimize the design of the structure and to pre-solve a series of problems that may appear in subsequent stages. Moreover, the realizations of the requirements are compared between the step-by-step redundant design and the integrated redundant design. And it is found that the step-by-step redundant design is a better design method.
