Reliability evaluation and improvement of manufacturing helicopter in an aircraft manufacturing company - case study: skid types helicopter landing gear

Abstract

Due to its sensitivity to time and accuracy, aerospace equipment requires a highly accurate manufacturing process to achieve higher reliability compared to other equipment. Focusing the studied helicopter, this study examines reliability of components of a landing gear manufactured by an aircraft company to improve total reliability of the product. Developing a model for risk-based design of a landing gear, this study proposes an inclusive approach for evaluating and promoting total reliability of the landing gear. Obviously, the reliability of components leads to the total reliability of product. This study identifies different components of a product to examine reliability of a component of that product. Then, the components are prioritised by FMEA for promotion to increase total reliability of the product. In conclusion, the objective of this study is to develop an inclusive model for improving reliability of mechanical components of landing gear manufactured by an aircraft company.
