Comprehensive Reliability of Aircraft Actuation System

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

Aircraft actuation system receives commands from the flight control computer and drives the plane surface to realize the aircraft flight attitude and flight trajectory control. The actuation system has a significant influence on the overall aircraft flight control performance and safety. This chapter presents the essential reliability characteristics of the redundancy aircraft actuation systems, and creates a reliability evaluation method for non-similar redundancy actuation systems. Section 1 summarizes the aircraft actuation system, and explains the interface between the flight control system(FCS) and the actuation system. Some typical aircraft hydraulic actuation system constructions in current commercial aircraft are provided in Sect. 2. Furthermore, Sect. 3 analyzes the architecture and characteristics of A380 aircraft actuation system, and provides the comprehensive reliability definition and the reliability calculation method. Afterward, the reliability of actuation system based on performance degradation is described. Finally, the integrated reliability evaluation case is provided for example of a HA/EHA system, in which HA operates actively and EHA follows under normal operating conditions.
