Enhanced Neural Network Model for Aircraft Flight Dynamics Prediction From Flight Test Data - Business Aircraft Application
Bibliographic record
Abstract
The ability to effectively detect data anomalies during flight test campaigns is highly dependent on the availability of a highly accurate mathematical model of an aircraft. However, identifying a model capable of accurately predicting the dynamics of an aircraft across the entire flight envelope remains challenging for engineers. This difficulty arises not only from the diversity of maneuvers performed during flight tests but also from the inherent complexity of aircraft dynamics. To address this challenge, a study was conducted at the Laboratory of Applied Research in Active Control, Avionics, and AeroServoElasticity (LARCASE) to propose an innovative methodology for identifying a model for a specific aircraft using Neural Networks. This artificial intelligence-based model was specifically designed to learn and predict the aircraft flight dynamics under a wide range of operating conditions. Compared to traditional time-series forecasting models, the proposed model aims to enhance generalization across various flight maneuvers and enable long-term forecasting. Results showed that the trained model was able to predict a set of aircraft flight parameters very well and within a predefined set of tolerances. By capturing long-term dependencies and efficiently generalizing model capabilities to any flight tests, the proposed model offers a promising solution to the problem of anomalies detection in flight testing.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
