Fault Tolerance, Diagnostics, and Prognostics in Aircraft Flight

Metadata Updated: May 2, 2019

Abstract

In modern fighter aircraft with statically unstable airframe designs, the flight control system is considered flight critical, i.e. the aircraft will encounter a catastrophic event if the system fails. Consequently, the system design has to meet high levels of reliability and failure immunity. In this presentation, an overview will be provided on the basic concepts employed in flight critical system design for fault tolerance. Different methods of redundancy implementation, failure management, and health management will be discussed. Basic concepts in fault diagnostics will also be discussed, along with some new concepts for implementation of prognostics in reducing levels of physical system redundancy.
