Design of Prognostic and Health Management Structure for UAV System

Abstract

As high-tech weapon systems, the failure prediction and maintenance support of Unmanned Aerial Vehicle (UAV) have attracted more and more attention. The traditional concept has been changed by using Prognostic and Health Management (PHM) on UAV maintenance support. The realization of PHM has changed the mode of UAV maintenance. The original maintenance mode base on existing incident (maintenance after fault happened) and time related mode (regular maintenance) will be replaced by the new mode based on the state (according to the state). In this paper, the PHM method used for UAV maintenance has been discussed. And by building a structure of PHM system for UAV system, the maintenance support hardware and software architecture is proposed and analyzed for further application.
