Fault Tolerant Operation in Aero Engine Using Distributed Computation System
Journal Title: The International Journal of Technological Exploration and Learning - Year 2014, Vol 3, Issue 2
Abstract
The paper presents fault tolerant operation in an aero engine based on real-time systems which is built for a very small set of mission-critical applications like space craft’s , avionics and other distributed control systems. The modern software deals with external interfaces and has to consider various timing implications The platform is based on the C and developed using Keil MDK tool with the targeted deadline of 100 milliseconds at the baud rate of 500 kbps. CAN interface executes the role of Transportation and Communication, an interface cable used for serial communication between Digital Electronic Control Unit (DECU) and the host to transfer data to the pilot Online Monitoring System and that is based on Laboratory Virtual Instrument Engineering Workbench (Lab VIEW )7.1. Fault diagnosis typically assumes a sufficiently large fault signature and enough time for a reliable decision to be reached. However, for a class of safety critical faults on commercial aircraft engines, prompt detection is paramount within a millisecond range to allow accommodation to avert undesired engine behavior. At the same time, false positives must be avoided to prevent inappropriate control action.
