VXP System Maintenance Manual 1-1

1. Introduction

This manual contains maintenance instructions, at the field-replaceable component level, for the

Honeywell VXP Vibration Analysis system. Operating instructions are provided only to the extent

needed to test the system. Components that are field-replaceable are defined as the major

components of the system, such as the FasTrak Optical Sensor. In addition, the cables used in the

VXP will be tested and repaired in the field, using MPI-001.

1.1 SYSTEM PURPOSE AND FUNCTION

The VXP is a lightweight system designed for vibration based maintenance. The VXP collects and

analyzes aircraft vibration data from sensors placed on-board the aircraft with a high degree of

accuracy. The VXP uses SmartChart

TM

balancing algorithms, developed by Chadwick Helmuth,

to compute and display optimal rotor balance and track adjustments. It can be used both in the

daytime and at night to perform rotor smoothing. The VXP is usually configured as a portable,

carry-on system. However, a permanent configuration is available that can serve to monitor

aircraft performance at preset intervals.

The main components of the VXP are the Acquisition Unit, the Display Unit, which is a small

Pentium notebook computer, the CompactFlash Card Adapter, Zio! USB CompactFlash Card

Reader/Writer, USB Floppy Disk Drive, and the printer. Additional equipment includes the

recommended accelerometers, velocimeters, photocells, magnetic pickups, and cables, as well as

the FasTrak Optical Tracker and the Strobex. In addition, the VXP interfaces with most industry

standard equipment.

The VXP is used for both balance/track operations and vibration analysis. As a balancer/tracker,

the system can be used to:

• Track and balance helicopter main and tail rotors.

• Balance propellers.

• Balance shafts and blowers.

• Balance high-bypass fans.

As a vibration analyzer, the system can be used for:

• On-condition maintenance through vibration trend analysis.

• Pre- and post-maintenance documentation.

• Hardcopy record-keeping of vibration on new or overhauled aircraft.

• Vibration data collection for the VibraLog System.

• Vibration troubleshooting.

1.2.1 Acquisition Unit

The Acquisition Unit (AU) is a microprocessor controlled signal analyzer which also has a

dedicated DSP processor. It has its own operating system, and runs application specific software

which performs specialized aircraft measurements and analysis. It contains four independent,

high-speed data acquisition paths, and can simultaneously collect and process four channels of

vibration data plus an azimuth signal and a tracker signal. The AU has a total of 48 special

vibration sensor interfaces, as well as built-in charge converters and photocell processors. It

operates from +28 Vdc aircraft power, and has an accessory power supply that can provide DC

power to the printer and Display Unit. It is housed in a rugged aluminum chassis, and is

environmentally sealed. The front panel has discrete connectors for accelerometer and/or

velocimeter inputs, azimuth inputs, power, FasTrak, Strobex, and communications interfaces, and

an expansion connector for additional vibration inputs and specialized interfaces. The Acquisition

Unit is shown in Figure 1-1.
