HIGH POWER MAGNETOSTRICTIVE TONPILZ TRANSDUCERS
Bibliographic record
Abstract
Due to the continuing interest of the French Navy (DCN & DRET), signi cant improvements have been made to magnetostrictive transducers to produce low-frequency, high-power sonar sources. Much progress has been made in the eld of Tonpilz transducers as a result of these improvements. The previous Quadripode transducer was built in two versions, Quadripode I and II. They had acoustic power of 1.0 and 1.6 kW, respectively. Next, an attempt to design a third version of the Quadripode led to a new Tonpilz transducer called the Tripode. Its purpose is to reach an acoustic power of at least 3 kW. It bene ts from magnetic circuit design results and from the giant dynamic strain capability of Terfenol-D (Peak-to-Peak strain higher than 2400ppm) discovered in 90-91. In this paper, the modelling results are reminded, and the results obtained from the rst series of inwater measurements of the Tripode are analyzed. These results tend to con rm expectations. of nding shading coef cients for any arbitrary array geometry and a given set of beampattern requirements.

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; both teacher heads agree on what is shown here.
