Automatic regime detection for Rotor Track and Balance using vibration only sensor data

Autor: D. Toshkova, Nicholas A J Lieven, Matthew Asher

Publikováno v: The Aeronautical Journal. 124:617-634

Rotor Track and Balance (RTB) is an important part of regular helicopter maintenance. The ability to perform this service assessment during normal operations, rather than with a series of explicit RTB flights, would greatly reduce the time the vehicl
