DI 137 TABS Analyzer Balancing System

The DI 137 TABS Automated Tracking Analyzer Balancer System (ATABS) is a complete solution to portable vibration analysis, simplifying helicopter and fixed-wing maintenance tasks while increasing aircraft performance.

ROTOR BLADE TRACKING

Rotor blade tip path corrections and lead/lag characteristics can be measured either day or night, using the optional line scan camera on the DI 137 TABS.

BALANCING
  • Single- and Dual-plane balancing
  • Discrete Fourier Transform (DFT) calculates phase angle and amplitude of the imbalance
  • Rotor smoothing algorithms provide simultaneous, multiple-maintenance adjustments
VIBRATION SIGNATURE

Fast Fourier Transform (DFT) and 4-channel simultaneous data acquisition capabilities are employed to yield fast, accurate vibration analysis results.

DURABLE

ATABS is intended for use in harsh and demanding environments and has been designed to meet:

TABS is intended for use in harsh and demanding environments and has been designed to meet:

  • Environmental Requirements of MIL-STD-810D
  • Shock and Vibration Requirements of MIL-STD-810D
  • EMI Requirements of MIL-STD-461C

Automatic test programs are created on your PC and downloaded to the TABS.  Pilots and technicians are guided through the data collection procedures by instructions displayed on the large, easy to read screen.

When data collection is completed, test results are displayed enabling the pilot or technician to quickly identify problem areas and the corrective actions necessary to solve them.

TABS supports all three Aircraft Maintenance Modes:

 Rotor Blade Tracking – Rotor blade tip path corrections and lead/ lag characteristics can be measured either day or night, using the optional line scan camera.

 Balancing – Single and dual plane balancing can quickly be performed.  A Discrete Fourier Transform (DFT) calculates phase angle and amplitude of the imbalance and rotor smoothing algorithms provide simultaneous, multiple maintenance adjustments.

 Vibration Signature – A Fast Fourier Transform (FFT) and four channel simultaneous data acquisition capabilities are employed to yield fast, accurate vibration analysis results.
