Abstract

fetched live from OpenAlex

Sustained aerial surveillance of wildfires provides crucial information on the state of the fire to aid with firefighting operations. In order to provide long-term aerial support, Unmanned Aerial Gliders are capable of utilizing their aerodynamic design to exploit fire-induced updraft generated by the substantial temperature differences in a wildfire environment. This work presents a guidance strategy which allows the glider to locate fire-induced updraft and exploit it. A high-fidelity simulation is developed by characterizing aircraft aerodynamics using Digital DATCOM and modeling the wildfire using WRF-Fire to capture the atmospheric effects of the fire on wind conditions. A cascaded control law is designed to achieve desired airspeed and course values, and a path following approach is implemented to generate the desired guidance commands. A thermal estimator based on an energy state of the vehicle is implemented to locate the point of maximum updraft during flight. To remain within the region of irregularly shaped fire-induced updraft, an oblong Dubins path is designed. Furthermore, based on the behavior of updraft in wildfire conditions, a path manager is proposed to efficiently locate the region of updraft and design the oblong path using the measured properties of the updraft distribution. Simulations are performed in various conditions which show the ability to efficiently locate fire-induced updraft and exploit it.

Teacher imitation

Not 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.
