Achieving Near Zero N/Rev Vibration with Zero-Vibe Technology
Bibliographic record
Abstract
This paper discusses the results of the proof-of-concept flight test of the Zero-Vibe™ system on a UH-60M aircraft. This flight test demonstrated the Zero-Vibe™ technology and its ability to achieve historically low vibration levels on a rotary wing aircraft. The Zero-Vibe™ system achieved better vibration reductions than the baseline UH-60M bifilar and Active Vibration Control System (AVCS) in steady level flight. Global vibration reductions were demonstrated which are unachievable with the current vibration control system architecture. The risk of a secondary n/rev vibration source due to wake impingement on the tail was realized during the test and was addressed with additional Circular Force Generators (CFGs) mounted to the tail. The data collected from this test showed clear improvement compared to the baseline AVCS demonstrating the overwhelming benefit of controlling vibration at the source.

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.
