VIPER II
Viper II Vibration Analyzer & Balancer
- Transient Fan/Turbine Balance
- Transient Vibration Survey
- Fan Blade Mapper
- TFE 731 Performance
The Viper II Vibration Analyzer is a versatile yet compact instrument that combines all of the diverse technologies required for high-end jet engine vibration analysis, transient balance, rotor track and balance, fan trim balance, propeller balance and acoustic analysis into one tool. All of these maintenance functions can be easily performed on virtually any airframe and/or engine type using the VIPER II.
TRANSIENT VIBRATION ANALYSIS
Accurate High-Speed Run-up & Coast-Down Transient Surveys
At approximately 6.0 pounds, powered by an internal battery and using minimal cabling, the VIPER II delivers vibration analysis at speed and accuracy levels typically available only in manufacturer test cells.
TRACK & BALANCE
Quick, Automated Track & Balance Solutions
The compact VIPER II provides accurate solutions in the minimum number of runs, saving costly run time and fuel. Setups are entered into the analyzer which can be customized by the user to accommodate virtually any engine and airframe type.
TRANSIENT FAN/TURBINE BALANCE
Save Time and Money by Collecting Data in a Single Sweep
Transient Balance is a method of collecting vibration data at all engine speeds during a balance run, eliminating the need to manually select and dwell at specific speeds. This is one of the most innovative features of the VIPER II, and it maximizes testing efficiency.
- Transient Balance yields test cell quality balancing results
- Direct PDF report generation onto a USB flash drive
- eSetups eliminate the need for charts
- SmartTach speed and phase processing allows direct measurement of the engine speed signal
- Four-channel simultaneous data acquisition (10 spectra/second/channel) for striking speed and accuracy
- Multiple speed inputs for multiple rotor speed tracking during transient analysis
- Multiple USB ports for direct connection to peripherals
