Abstract

fetched live from OpenAlex

The original 505 Jet Ranger X prototype used a simple hard-mounted focal pylon to attach the transmission to the airframe. In developmental flight tests, the design resulted in 2/rev vibration levels that exceeded program objectives for ride quality in high speed forward flight. To address the vibration levels, a LIVE pylon mount was designed over a 4-month period to serve as a drop-in replacement with minimal impact to existing systems. An overview of the rapid design process is presented with supporting analysis and test data that led to its incorporation on the aircraft. The LIVE pylon design cut the vertical 2/rev vibrations in half, without negatively impacting existing structures, drive systems, flight controls, or handling qualities. The LIVE pylon mount is part of the Bell 505 Type Design that was certified in December 2016.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
