additional capabilities
Helicopter Single Plane Rotor Balance
FasTrak Rotor Track
Additional capability includes saving auto-corrected charts under user defined names.
EV2K+ Evolution
– EV2K+ was meant to help bridge gap between V2K+ and VXP due to 8500 obsolesce
– EV2K+ development based upon V2K+ hardware and VXP software
This approach was used to obtain reasonable time to market
EV2K+ unit identical to V2K+ unit except for logo plate
Based on standard V2K+ features, menu architecture and code
New helicopter balance features were added using core VXP code
Some existing V2K+ features were updated
What Separates the EV2K+ from the V2K+?
In addition to the standard V2K+ features the EV2K+ adds:
– Simple helicopter balance solutions for most small and medium helicopters
– Strobex tracking expanded to include FasTrak operation
FasTrak pre-tuned to same aircraft as helicopter balance
– User editing and storage of new configurations:
Propeller balance
Blade tracking configurations
Helicopter balance models
– Four channel operation
Helicopter Balance Charts
New addition for the EV2K+.Provides solution based adjustments.Very versatile solution dictation by the user.
• Can solve for vertical, laterals, and fore/aft requirements independently
• Alternate solutions available
Save and rename user define charts for precision balancing of the customers unique airframe.
Auto-correction to improve balancing efficiency
Principles of Operation
EV2K+ helicopter balance based VXP algorithms and models
VXP runs one application at a time – EV2K+ pre-programmed with over 25 aircraft types
Like VXP, EV2K+ has one execution model space
Desired application is loaded from stored list into that space
Only one balance model can be run at a time
Same VXP balance components (bcomps) are used
Same VXP “charts” (influence coefficients) are used
Some charts are marked as “excluded” (not used)
Charts with zero or very low sensitivity are excluded (e.g. 2000 P/L flats per IPS)
Some charts not normally used for RTB are excluded
One bcomp for balance
One bcomp for FasTrak
They are loaded as needed based upon menu selections
The two bcomps work independently in both menu operation and execution
Helicopter and FasTrak components can be user edited and stored under on new name “Auto-corrected” coefficients can also be stored.

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


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


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.
Portable Printer “DPU-414-M”


This line printer makes it comfortable for the user, to get printouts at the aircraft, without the need of a PC Printer in an office.
Its rechargeable battery allows printing even without supply power from the aircraft. The rechargeable battery is charged via the Acquisition Unit of the Carry-On VXP.
Vibration Sensors


High Temp. Accelerometer used for vibration test and analysis on turbine engines.
Accelerometer 4177B, P/N 4109 used for the legacy VIBREX System with Balancer 177M-6.
Azimuth Sensors


Photo Probe , P/N 10200-1 typically used as RPM and azimuth reference for dynamic balance measurement of tail rotors, drive shafts and blowers, with 8500C(+) and Carry-On VXP.
Photo Probe , P/N 12900 typically used as RPM and azimuth reference for dynamic balance measurement of tail rotors, drive shafts and blowers, with V2K(+)

Basic Sensor Brackets

The Photocell Bracket P/N 10423(-1) is used for installation of the Photo Probe , P/N 12900.
Aircraft specific Brackets for Accelerometer 4177B and Velocimeter 7310 are offered as part of Application Kits, if needed.
Application Kits

The required Application Accessory is quoted specifically for the various “Portable Systems” and aircraft/engine type.
Brackets and Interrupters


Interrupters are aircraft specific parts made of magnetic Stainless Steel which generates an RPM and azimuth reference when passing the Magnetic Pickup.
Brackets and Interrupters are available for many helicopter and fixed-wing aircrafts, as part of the Application Kit for “Zing® Test” Systems.
Adapter Cables


Breakout Cables are used for aircrafts which have a partly or complete hardwiring for DC Supply power and sensors of the “Zing® Test” Systems.
Application Software


The “Advanced Smart Charts” of the Carry-On VXP allow simple/quick data collection of Track & Balance of one or multiple regimes and calculate rotor adjustments for Track and/or Balance respecting current settings and rotor limits.
For 8500C(+) Chart Sets are provided in form of a 3.5” Floppy Disk, containing “Smart Charts” available for almost any helicopter and turboprop aircraft type as well as for some turbofan engines.
Precision Tab Tools (optional)


Precision Tab Tools are available for many different helicopter types from Honeywell, supplied with calibration plates and instructions and partly with a specific carrying case.
