Airworthiness Design and Analysis of Compliance Demonstration forReversing System

Abstract

Most of the modern turbojet airplanes are installed with reversing system, which can promote the economy, availability and safety of airplanes. However, failures of reversing system may have significant effect on airplane and people on-board and on the ground. The design and compliance demonstration of reversing system is also one of the key certification issues that the authorities usually focus on. Through the analysis of regulations, Advisory Circulars(ACs), and amendments of CAAC, FAA and EASA, the applicable airworthiness requirements and their brief analysis, the controllability and reliability compliance options and respective considerations of turbojet reversing system are illustrated. Additionally, the reliability option is applied to a specific aircraft reversing system, and the exact compliance demonstration items as well as compliance conclusion are given. The results can provide a useful reference for airworthiness design and compliance verification of aircraft thrust reversing system in china.
