Abstract

The ground-steering system is a part of the nose landing gear of an aircraft, which is fundamental to its safety. The sensing mechanism for the nose wheel direction uses multiple redundant sensors to estimate the same controlled signal. In practice, these sensors are subject to uncertainty and faults, so that it is vital to reliably estimate the controlled signal under these conditions, but also to assess the degree of confidence with which each sensor should be treated and hence the overall integrity of the estimated steering angle. This presentation describes how a digital twin of the ground-steering system, in which the effect of uncertainties and faults can be systematically analysed, is used to assess the integrity of the estimation. This digital twin will also be exploited to investigate novel types and arrangements of sensors, to test how the safety and reliability of the system could be improved by redesign.
