CDB Supports Condition Based Maintenance (CBM) Concept
CDB is not a health monitoring system that only collects data for future
analysis. CDB uses collected data to affect changes in drivetrain balance to
eliminate/reduce dynamic component and resonant high frequency vibrations in the
drivetrain and airframe. 
CDB supports the Condition Based Maintenance (CBM) concept by providing
Reliability, Availability, and Maintainability (RAM) data that supports
predictive maintenance practices based on actual conditions of dynamic
components vice unscheduled maintenance, thereby reducing extensive aircraft on
ground events. The CDB technology aims to increase fleet readiness and reduce
operation and support costs.
CDB is a CBM enabler in that it complements existing data source collectors
such as Health Unit Monitoring Systems (HUMS) and Modernized Signal Processor
Unit (MSPU). CDB goes a large step beyond just monitoring and actually provides
an elegant mechanical solution to reduce destructive high frequency harmonic
resonant vibrations that shorten the life of parts, create serious safety
issues, increase costs, and are responsible for a number of collateral damage
concerns. CDB could be integrated into these monitoring systems in the future as
needed, thus increasing the capability of such systems.
Assumptions - AH 64 Apache Helicopter
• Due to the Global War on Terror operational tempo (OPTEMPO) will demand maximum availability for the AH-64 Apache for years to come.
• If current OPTEMPO is continued, the AH-64 Apache will reach airframe life-cycle limits much earlier than planned.
• Insufficient funding for research and development of replacement aircraft will require the US Army to sustain the AH-64 Apache for many years to come.
• The vibration state of Block III Longbow’s new main transmission is as yet unknown; as are the systemic resonant influences a new or different vibration state may bring to the drive train and airframe as a result of a new transmission.

"We did CDB on two of our Apaches, AH-64A 120 and AH-64D 006. I have flown both and can tell you that it has made an obvious difference. Not only are the vibrations way down, it seems that the noise in the cockpit is quieter. We are impressed enough that we would like to arrange for these guys to return and do AH-64A 214 for us as it was not available during the demo."

"I think this will be an excellent addition to the aircraft especially once it is incorporated into the MSPU. With the addition of sensors in other critical locations, it will further improve our ability to detect issues with the aircraft before it escalates to the failure of a component and possible saving lives and equipment. That in itself makes it worth having the program."
