Remaining Useful Life Prediction in an Aerospace Engine: A Multivariable Fuzzy Time Series Classification Approach

open access: yesExpert Systems, Volume 43, Issue 2, February 2026.
ABSTRACT Failures in safety‐critical systems such as aircraft engines pose severe economic and societal risks. This study introduces a novel Remaining Useful Life (RUL) prediction method uniquely combining diverse techniques. Specifically, the proposed methodology integrates fuzzy time series analysis with sliding window segmentation and Multinomial ...

LCA‐based evaluation of greenhouse gas reduction potentials of carbon/carbon wheel brakes for medium‐haul aircraft

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Air transport is expected to substantially grow in the next decades, presenting a significant challenge for the aviation industry to reconcile this growth with the need to mitigate climate change by reducing greenhouse gas (GHG) emissions. A viable strategy for diminishing aviation emissions involves reducing aircraft fuel consumption, which ...

Learning Among Military Helicopter Crew Members: The Hidden Potential of Emotions

open access: yesScandinavian Journal of Psychology, Volume 67, Issue 1, Page 1-11, February 2026.
ABSTRACT How can we learn from critical incidents? We argue that emotions have a hidden potential to construct complete experiences and learning. This study aims to develop knowledge about emotions' role when military aircrews debrief to learn from experience.
