Advances on the Next Generation Short-Medium Range Aircraft Rear End: The CleanSky 2 Project IMPACT
Bibliographic record
Abstract
Abstract This paper aims at presenting the results of the CleanSky 2 European project IMPACT (GA no. 885052), granted under the Large Passenger Aircraft Integrated Technology Demonstrator (LPA-ITD), aiming at optimizing the rear-end design for the next generation Short and Medium Range (SMR) A320-like aircraft. Specifically, the project has investigated a Forward Swept Horizontal Tail Plane (FSHTP) enhanced with a Leading-Edge eXtension (LeX) device. The activities have focused on the optimisation of the horizontal stabilizer, accounting for the coupled aerodynamic, aeroelastic and, for the first time, icing behaviour. The optimal solution provides significantly better lift performance of the tailplane (i.e. up to 12.4% increase in C L ), limiting the drag penalty to below 1.0% in cruise condition (i.e. between 0 and 2 degrees of Angle of Attack).

How this classification was reachedexpand
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.
