System PHM Algorithm Maturation
Authors: Massé Jean-Remi , Hmad Ouadie , Boulet Xavier 
Published: March 2024

The maturation of PHM functions is focused on two Key Performance Indicators (KPI): The NFF, No Fault Found ratio, P(No degradation|Detection), and the Probability Of Detection POD, P(Detection|Degradation). The estimation of the second KPI can be done by counting the global abnormality threshold trespassing when each different kind of degradation is simulated. The estimation of the first KPI can be done through the following formula using the Bayes rule:( )( | )* ( )( | )P DetectionP Detection NoDegradation P NoDegradationP NoDegradation Detection P(Degradation) may be known through FMEA or field experience. Typically, for a probability of 10-7, a specified NFF ratio of 1%, and an expected POD of 90%, the order of magnitude of P(Detection| No degradation) should be 10-9. The estimation of such extreme level of probability needs some parametric adjustment of the distribution of the global abnormality score with no degradation. Two PHM functions are considered as case studies: Turbofan engine start capability (ESC) and turbofan engine lubrication oil consumption (EOC). In ESC the global abnormality score is a norm of a vector of specific abnormality scores. The specific scores are centered and reduced residues between expected values and observed values. Some specific scores are devoted to starter air supply. Examples are duration of phase 1 from starter air valve open command to ignition speed. Other scores are devoted to fuel metering. Examples are duration of phase 2 from ignition to cut off speed. The expected values are estimations through regression relations using as inputs the other specific scores and context parameters such as lubrication oil temperature at start. The regression relations are learnt on start records with no degradations. Impact simulations of degradations on specific scores are learnt on a phase 1 simulator based on torques balance and on start test records including fuel metering biases. In EOC, the global abnormality score is the daily weekly or monthly consumption estimations on a daily basis. Consumption estimations use linear regressions of oil level measurements versus time at an invariable ground idle speed corrected according to oil fill detections and oil temperature. The over consumptions are simulated by drifts in mean of the consumption estimations.To reach acceptable POD at the specified NFF ratio three improvements are needed for ESC:  Adjust the abnormality decision threshold according to each candidate degradation using extreme value quantiles on the global abnormality score distribution Average the global abnormality score on five consecutive starts Learn the regression relations specifically on each engine.The first improvement is a novelty. It is successfully applied to both ESC and EOC functions. It is generic to all airborne system PHM functions based on abnormality scores.
Enhanced Particle Filter framework for improved prognosis of electro-mechanical flight controls actuators
Authors: De Martin Andrea , Jacazio Giovanni , Sorli Massimo 
Published: March 2024

The technology of flight control actuators is at the forefront of the “more electric aircraft” research trend since its beginning, due to the several advantages that the introduction of Electro Mechanical Actuators (EMAs) would provide over the traditional hydraulic/mechanical solution for both primary and secondary flight control surfaces. However when compared to hydraulic actuators, technological barriers still persist for a wide adoption of EMAs especially when considering their sensitivity to certain single point of failures that can lead to mechanical jams, resulting in a reluctance to adopt EMAs for flight safety critical applications as solutions are heavy and costly (redundancy, fail safe behavior, etc.), thus creating difficulties for adoption and certification and impacts on costs. The development of an effective and reliable PHM system for EMAs could help mitigating the risk of a sudden critical failure by properly recognizing and tracking the ongoingfault and anticipating its evolution, and will offer a possible way contributing to the acceptance of EMAs as primary flight control actuators in commercial aircraft. The paper firstly presents an enhanced Particle Filter framework for improved prognosis, discussing its benefits and its implementation inside a general PHM framework developed for EMAs. Then, three significant examples of its application are provided relevant to an electrical and a mechanical fault of the EMA: degradation of the electric motor and backlash increase in the mechanical transmission due to the growing wear of its components. The positive results obtained from the application of the enhanced Particle Filtering framework to these faults provide good confidence on the possibility of extending it to other EMAs faults and to successfully implement this technique to EMAs for flight control actuators.
Insight into Wind Turbine Planet Bearing Fault Prediction Using SCADA Data
Authors: Koukoura Sofia 
Published: March 2024

Condition based maintenance is being adopted into the decision making process of wind farms, in order to reduce operation costs. SCADA systems are integrated in wind turbines, providing low frequency operational data and are increasingly being used in condition monitoring. The aim of this paper is to explore how can wind turbine gearbox components be monitored using SCADA data. The proposed methodology utilises 10-minute averaged data. Data preprocessing is applied using a clustering filter in order to improve prediction confidence. Normal behaviour models are used to predict potential faults. The efficacy of the proposed methodology is demonstrated with a case study using SCADA data from three operating wind turbines that have a double planetary stage gearbox. Historic data is collected for more than a year before the occurrence of a bearing failure on a planet of the first planetary stage. The case study results indicate the potential importance of generator speed estimation for planet bearing faults. A successful prediction of the bearing health state can be performed through this model and some insight is given into into the optimal SCADA sensors utilization for this type of failure mode.

Polarimetry of GRB 230818A

Published: March 2024

Abstract
We present a preliminary analysis of optical photometric and polarimetric observations of GRB 230818A obtained with the Liverpool Telescope starting 3.2 minutes after the alert. The optical photometry suggests a reverse shock-dominated afterglow, transitioning to forward shock at around 15 minutes. The polarization shows a low degree (upper limit 6%) early in the light curve. This is in contrast to the expected result since this regime should be dominated by the reverse shock wave that, in turn, should present a higher degree of polarization.
