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.

"...[balancing of the Bell Jet Ranger 206B3] was accomplished with one-third of the test flights that other systems required..."

"...I have found the ACES Systems Model 2020 ProBalancer to be a very reliable piece of equipment. It has an easy installation, it's easy to use and understand, not to mention that it's been a real time-saver. It is not uncommon to have the Robinson R22 and R44 helicopters balanced to .02 IPS. That's quite impressive!"

"...the Aces is the best portable unit I have used. It requires no additional battery or ship's power and no blade targets. If you have ever been halfway through a tracking flight (particularly with a Bell 412) and had a target come off, you will know how frustrating this is...and expensive."

"...using another system, it took over 20 cycles and two days to track and balance our MD500D. Since purchasing the Model 2020 (ProBalancer), we have properly balanced our MD500D in 5 cycles, and it took less than one day."

I would like to extend our thanks for the above and beyond assistance you guys provided for us in the time of need to get our test cell up and running in a timely manner. The level of support and service that was provided was without a doubt one of the best we have ever had.

Your team seemed to drop everything to help us with the questions that arose and were very accommodating to help us with the growing pains to understanding the system. You also pulled out all of the stops to get us a rental unit to support our Viper when our unit went down and expedited it through your shop to have it back to us as quick as possible.
