Aerodynamic aspects in the development of morphing winglet for a regional aircraft
Bibliographic record
Abstract
An aerodynamic analysis is conducted for morphing winglets on a regional aircraft. The optimum drag, bending moment, stall angle and maximum lift coeffcient are evaluated for various mission segments by varying winglet design parameters. Aero-elastic studies are conducted in order to incorporate wing deformation effects in addition to exploring maneuver load alleviation capability of the morphing winglet. The results show drag benefit up to 1% in cruise and wing bending moment and winglet bending moment benefits of 2.4% and 63% at 2.5g symmetric maneuver conditions. The total aircraft drag benefit translates to additional allowable structural weight that can be applied to the design of winglet actuation system. The morphing winglet shows superior stall behavior and attenuates high wing loads. The estimated wing-winglet loads will help in proper selection of actuators. This study is also expected to help in elevating technology readiness level of the morphing winglet technology.

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.
