Abstract
Helicopter aerodynamic modeling has always received growing attention especially in the applications such as model-based control design for the helicopter UAVs, in which the vehicle model is of utmost importance to obtain a satisfactory performance. This article is an attempt to derive a general aerodynamic model for the small helicopters in the steady flow regimes. The actuator disc concept together with blade-element theory has been widely used in the helicopter performance calculations for many years. Based on this approach, a more comprehensive analytical model of the blade aerodynamics has been developed in this paper, by incorporating the vehicle velocity and angular velocity vectors into the model, which makes it suitable for the rotorcraft modeling and control in general flight scenarios. The simulation results for different flight regimes verified the correctness of the proposed model, and an experimental setup is used to verify the helicopter aerodynamic model around hover.

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 it
