Vibrex™ 2000 and Vibrex™ 2000 Plus

Whether you have a fixed-wing aircraft, helicopter, turbine or reciprocating engine, there’s a Vibrex 2000(+) to meet your needs. The Vibrex 2000(+) is a vibration analysis and balancing tool that rapidly and accurately acquires and analyzes aircraft.The “Smart Balance Chart” calculates balance weights for Propellers and rotors for Propellers of any size and type with weight splitting and automatic sensitivity. Vibrex 2000(+) uses Stroboscope for visual rotor tracking & Lead/Lag Check.

The balancer/analyzer for fixed-wing or rotorcraft

The balancer/analyzer acquires accurate propeller and helicopter vibration readings. The Vibrex™ 2000(+) will balance propellers without the need of a chart or use the available Chadwick paper charts or factory charts, to balance your helicopter. Also capable of balancing shafts and blowers, the Vibrex™ 2000(+) is a complete balancing tool. As a spectrum analyzer, it provides the operator with an overview of rotor and drivetrain vibration.

2 models to fit your needs

Vibrex™ 2000

The basic Vibrex™ 2000 is applicable to aircraft and engines with component frequencies of 20,000 rpm or less and balance speeds below 10,000 rpm. For recipe powered aircraft, the Vibrex™ 2000 basic model is a sure fit.

Vibrex™ 2000 Plus

For applications where there is a need to perform higher frequency spectrum analysis, such as a turbine engine, the Vibrex™ 2000 Plus measures to 600,000 rpm. The Vibrex™ 2000 Plus model also adds a spectrum viewer for on-screen graphical display of spectral data. Both models provide easy-to-use features that assist the maintainer in decreasing maintenance time, lowering maintenance costs and increasing aircraft availability.

4 easy steps to FAA-approved prop balance

Easy to understand menus allow the user to initiate and complete up to 4 different balancing jobs at one time. The instrument will automatically correct for the propeller response to weight changes and this correction can be saved for future balancing exercises.

A “first round hit” solution means less vibration, even on the first adjustment. Two channels allow the user to measure the propeller and rear of the engine during balancing. All measurements, sensitivities, solutions, and annotations are stored in memory and can be reviewed on the instrument, printed on the optional portable thermal printer, or downloaded to a personal computer.

Customized Kits Available

The Vibrex™ 2000 product line comes as a complete kit, with all the software, accessories, and instructions for your particular application in a rugged, portable carrying case. With over 45 years of experience on more that 300 different applications, Honeywell-Chadwick systems are proven and reliable.

Pinpoint problem components Spectrum Analysis

Use the Vibrex™ 2000 spectrum feature to pinpoint problem components with ease. The “List Peaks” spectrum printout identifies the highest peaks quickly. Use the harmonic and order features to identify misalignment, mechanical looseness, or imbalance to guide your maintenance action.
An added feature of the Vibrex 2000 Plus model is a simple yet sophisticated spectrum viewer.

Visual Blade Tracker “Strobex 135M-12” P/N 8620

This Blade Tracker is used with V2K(+), Carry-On VXP and 8500C(+) to observe the Track & Lead/Lag of main rotors and also tail rotors of helicopters.

It requires “Tip Targets” on the blade tip which are usually part of the Application Kit for V2K(+), Carry-On VXP and 8500C(+).

Observed Track & Lead/Lag data are either recorded on a tracking record sheet or entered in the 8500C(+) “Smart Chart” to be respected in the calculated Track & Balance adjustments.

Optical Blade Tracker “FasTrak” P/N 11800-3

This Day/Night Blade Tracker is used with the 8500C(+), Carry-On VXP, On-Board VXP and VMS II for fast Track & Lead/Lag measurement of main rotors of helicopters within +/- 1 mm accuracy.

When used with Carry-On VXP the Track & Lead/Lag data are collected simultaneously while measuring the dynamic balance.

For use at night, a Retro Reflective self-adhesive tape is used at the trailing edge of the rotor blades to reflect the emitted IR light of the IR LCD ring below the cover glass.
