The VIPER 4040 is a versatile yet compact
instrument that combines all of the diverse technologies required for high-end engine
vibration analysis, rotor track and balance, propeller balance, fan trim balance, and
acoustic analysis into one. All of these aviation maintenance analysis functions can be
easily performed on virtually any airframe and engine type using the VIPER 4040. Track
and Balancing
Quick,
Automated Track and Balance Solutions
The compact VIPER 4040 provides accurate solutions in the minimum number of runs, saving
costly run time and fuel. Setups which can be customized by the user to accommodate a
number of engine and airframe types are entered into the analyzer. Potentially hundreds of
job setups can be stored in the VIPER 4040’s 32 MB of memory and recalled for quick
reuse. Using the VIPER 4040’s ChartBuilder™ function, influence and adjustment
criteria from polar charts can be entered into setups so that raw data acquired is
automatically translated into easy-to-follow adjustment solutions such as “inboard
tab up 2 degrees.” With four channels available for simultaneous data acquisition,
the VIPER 4040 gathers data quickly. With each run, the analyzer adjusts and refines the
solution based on data gathered during previous runs, taking into account the unique
properties of each job and automatically shortening the process until vibration is reduced
to the lowest level possible. The flexible VIPER 4040 allows you to use any type of
tachometer, detecting speeds at up to 32,000 RPM. Tach input is used to synchronously
sample and average data and report phase to +/- 3 degrees, reproducible to 1 degree. For
additional flexibility, the VIPER 4040’s SmartTach™ speed and phase signal
processing uses single or double interrupter, high tooth, low tooth, offset tooth, or
standard TTL inputs.

Run-up and Coast-Down Transient Surveys
The VIPER 4040 offers striking capability in a compact, portable package. At 7.3 pounds,
powered by an internal battery and using minimal cabling, the VIPER 4040 delivers
vibration analysis at speed and accuracy levels typically available only in manufacturer
test cells--vibration data acquired from up to four channels simultaneously at the rate of
10 spectra per second are recorded at frequency levels to 30 kHz per channel.
Anti-aliasing filters are used with a Fast Fourier Transform (FFT) to convert data from
time to frequency at resolutions of 100, 200, 400, 800, 1600, and 3200 lines. The massive
amounts of data acquired in a transient are easily stored in the VIPER’s cavernous 32
MB of memory. And, the flexible architecture of the VIPER 4040 allows you to use virtually
any sensor type.
Acoustic
Analysis
The VIPER 4040 can interface to microphones for measuring sound levels and frequencies in
order to diagnose airframe noise problems.
