As the newest member of the Honeywell Chadwick Helmuth Health and Usage Monitoring System (HUMS) family, the Enhanced VXP (EVXP) provides the features and functions to meet increasing regulatory and customer-driven requirements for an aircraft health monitoring system.

Honeywell Chadwick Helmuth’s EVXP System monitors aircraft health, operational, and usage parameters. In order to be able to meet all of the basic maintenance requirements, the system performs data management, enhanced vibration diagnostics for detecting issues, event or exceedance detection, main rotor track and balance, tail rotor balancing, operations usage recording, and system functions

Honeywell Chadwick Helmuth EVXP Benefits/Features :

Simultaneously collecting data from up to four vibration, azimuth and tracking inputs

Collecting both vibration and Rotor Track and Balance flight regime data in any order, thereby providing flexibility during dedicated flight tests and eliminating the need to restart tests

Providing immediate feedback of vibration exceedances via the DU, thereby eliminating the need to review the data post-flight using the ground station software. Comprehensive ground support software tools available for flight crews, maintainers, and engineers with capabilities to interface with operators’ maintenance system

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.

Portable Printer “DPU-414-M”

This portable printer is used for V2K(+), Carry-On VXP VMS II and On-Board VXP to make printouts of rotor settings, measured data and rotor adjustments as well as predictions for the calculated adjustments.

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.
