AUTOMATIC HELICOPTER MAINTENANCE MONITOR

摘要

PURPOSE: To allow a pilot control a helicopter in a specific operating state wherein helicopter maintenance becomes facilitated, by generating a trouble signal according to a vibration detecting signal exceeding a specified value, and simultaneously installing a processing means wherein the specified value is each function of the vibration detecting signal and a helicopter status. CONSTITUTION: A data acquisition unit 36 processes input data. A fast Fourier transform is executed to vibration data from a accelerometer, whereby a set of digital data showing the size of vibration measured as a frequency function by each accelerometer are offered. Flight sensor data are transferred to a processor 40 from a flight data recorder 26 via a bus 48. In the case where a monitoring system 20 is operated by a monitor mode or maintenance mode, diagnostic software automatically collects data from the sensor, displaying status information. Any trouble shown by the collected data is reported to a user via a cockpit display 28.
