Abstract
View Video Presentation: https://doi.org/10.2514/6.2022-0757.vid This paper develops a method to model the air flow downwash effect generated by the quadrotor unmanned aerial vehicle (UAV) and its effect on the neighboring UAVs. The downwash model derives the resultant downwash force and torque and takes the UAV attitude into the account. Each UAV is shaped by a virtual structure for collision-free path planning. The shape is modified from a standard spherical body to a proposed cylinder to better minimize downwash impact. A flock-based path planning algorithm and an optimal reciprocal collision avoidance (ORCA) algorithm are implemented and investigated in this study to analyze the downwash effect and the performance of the proposed cylindrical shape UAV model. The downwash model simulation shows how the UAV can be affected when it counters the downwash air flow. A flock-based algorithm and an ORCA algorithm along with the spherical and cylindrical shape UAV models are simulated to demonstrate the cylindrical model can improve path planning performance.

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 it
