Remaining Useful Life Prediction of a Turbofan Engine Using Deep Layer Recurrent Neural Networks
Bibliographic record
Abstract
Turbofan engine is a pivotal component of the aircraft. Engine components are susceptible to degradation over the life of their operation which affects the performance of an engine. In order to direct the necessary maintenance behavior, remaining useful life prediction is the key. This thesis presents a prediction framework for the Remaining Useful Life (RUL) of an aircraft engine using the whole life cycle data and deterioration parameter data based on a machine learning (ML) approach. In specific, a Deep Layer Recurrent Neural Network (DL-RNN) model is proposed to address the problem of prognostic instability based on deep learning. The proposed method is compared against Multilayer-Perceptron (MLP), Non-linear Auto Regressive Network with Exogenous Inputs (NARX), Cascade Forward Neural Network (CFNN) and validated through the Prognostics and Health Management (PHM) conference Challenge dataset and C-MAPSS dataset provided by NASA results reveal a better predictive precision with respect to other ML algorithms.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
