Experimental Validation of Vertical Lifting Capabilities of Circling Tethered Fixed Wing UAVs
Bibliographic record
Abstract
The Electric-Powered Reconfigurable Rotor VTOL Concept (EPR2 ) is a novel type of VTOL aircraft that uses tethered airplanes flying collaboratively along a near circular flight path to lift a payload. The objective of this paper is to experimentally assess the vertical lifting capabilities of a single tethered fixed wing aircraft flying along a circular flight path anchored to the ground using a small-scale testing platform. Results show that the airplane has the ability to lift up to 4 times its empty weight with off-the-shelf components along an unoptimized flight path. This new concept also requires considerably less power than other conventional VTOL aircraft to lift the same payload, reaching a payload-to-power ratio of 13 grams per Watt. The maximum lifting capability and efficiency are then evaluated using a numerical model of the system in a constrained nonlinear multi-objective optimization function. It is shown that the same airframe with minimal modifications could lift up to 8 times its empty weight at a payload-to-power ratio of 26 grams per Watt.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
