State-Of-The-Art And Directions For The Conceptual Design Of Safety-Critical Unmanned And Autonomous Aerial Vehicles
Bibliographic record
Abstract
Unmanned and Autonomous Aerial Vehicles (UAV/AAV) must be safe and reliable to prevent catastrophic accidents in population-dense areas. The study reveals the absence of a comprehensive UAV/AAV design for reliability approach in the open literature; in particular, there is no conceptual design methodology including safety and reliability considerations in the sizing. This finding leads to investigating the relevance of pursuing this research direction and identifying the challenges to address. For this matter, a straightforward approach combining sizing, systematic redundancy, controllability, and reliability assessments compares a conventional to a redundant design in a case study. The reliability analysis confirms that the redundant design is fault-tolerant and potentially highly reliable. However, the total mass almost doubles due to the lack of sizing and redundancy optimization. Plus, there is a high risk of under-sizing due to the limitations of a straightforward approach. This result emphasizes the need to develop a new conceptual design methodology based on sizing, including safety and reliability considerations. The paper concludes with research directions towards this goal. Thus, optimized redundant designs will contribute to the emergence of UAV/AAV for safety-critical applications in the near future.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
