Honeywell 8500C Plus Balancer (Chadwick-Helmuth)
Overview
The Honeywell Chadwick-Helmuth 8500C Plus is the balancer version of the 8500C family, a portable digital computer and FFT analyzer for rotor track and balance, fixed wing propeller track and balance, helicopter and fixed wing vibration surveys, and vibration analysis and trend analysis. The Plus configuration carries the full analyzer functionality with the bright backlit display, integral printer, built-in help and Smart Chart technology. The instrument computes the balance solution from the acquired vibration and tachometer data and prints the report at the aircraft, which makes the 8500C Plus a complete carry-on balancing station.
The 8500C Plus balance job is completed in one session: the kit is installed, the data are acquired during the run-up, the corrections are computed with the track readings and the report is printed at the aircraft. The FFT analyzer resolves the vibration signal into the rotor and propeller components, and the Smart Chart technology guides the operator through the solution. The memory stores the configuration per aircraft type, so the same instrument serves the complete fleet without re-entering the parameters.
Engineering and Design
The balancer acquires the vibration signal from the sensor mounted on the aircraft pick-up point and the speed reference from the tachometer, then resolves the amplitude and phase at the rotor or propeller speed. Track data from the blade markers is entered into the unit, and the computer calculates the corrections required on the adjustable blades or the balance weights. The integral printer issues the balance report and the correction data immediately, eliminating transcription errors between the aircraft and the workshop.
The Smart Chart technology built into the unit replaces the paper charts of the older instruments with the stored factory charts, and the built-in help guides the operator through the procedure step by step. Because the same acquisition routine is used for surveys, the 8500C Plus also supports vibration analysis and trend analysis between scheduled maintenance events. The instrument is supported by the Chadwick-Helmuth calibration and repair service operated by Diagnostic Solutions International.
Before the balance run, the 8500C Plus is configured with the rotor geometry and the sensor channel for the aircraft, and the tachometer input is connected to the speed reference. During the run the operator records the blade track data while the analyzer acquires the vibration signal, and the computer computes the corrections from the combined data set. The report is printed at the aircraft, showing the measured amplitudes, the phase angles and the recommended adjustments, so the crew applies the corrections and verifies the result on the next run. The same unit supports helicopter and fixed wing procedures, which reduces the number of instruments required for a mixed fleet. The analyzer memory stores the survey data for trend analysis, and the Smart Chart technology replaces the paper charts of the older instruments. The unit is verified against the reference vibration source during the annual calibration, and the spare parts, sensors and accessories are available from the Chadwick-Helmuth service organisation. For MRO workshops that operate several aircraft types, the configuration parameters are stored per type and recalled at the start of each job.
