Performance Exploration of Vertical Payload Lifting Using a Single Circling Tethered Fixed-Wing Aircraft
Bibliographic record
Abstract
Since the beginning of the 2000s, concepts for transporting payload with multiple tethered aircraft have been proposed to balance the lateral loads on a stationary payload. An alternative, initially developed in the 1940s considered a single aircraft and long tether to minimize the lateral motion of the payload during the circling motion of the aircraft in hover. To shorten the tether and reduce the drag losses associated, a concept with a single aircraft and an active stabilization system on the payload is proposed. This paper demonstrates that a single Pipistrel Sinus can vertically lift a stabilized underslung payload of 660 lb (300 kg) at 6,000 ft (1,800 m) under temperature conditions of 95 deg F (35 deg C) with less than 47 hp (35 kW) and a reduction of 70% of the tether length compared to a non-stabilized payload.

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.
