An Afghan air force airman uses a mallet to remove the blade mount bolt so that one of the main rotor blades of an AAF Mi-17 helicopter can be lowered safely to the ground at Kabul International Airport, Kabul, Afghanistan, Oct. 5, 2011. The airmen were removing the blade to solve a vibration problem with the helicopter.


address these problems have mostly focused on monitoring vibration data in an attempt to predict useful life of dynam- ic components or to warn of imminent component failure. None of these solutions were intended to actively reduce or eliminate the damaging vibration, only to monitor it.


A NEW SOLUTION Customized Dynamic Balancing (CDB) is a unique,


newly developed technology that employs a complex pro- prietary set of algorithms aimed at eliminating destructive vibrations considering the whole drive train as one unit. Beyond just monitoring for vibration, the CDB algorithms analyze collected vibration data to determine the specific solution for each individual aircraft in order that its drive- train may be custom balanced, eliminating vibrations. Each aircraft drive train is then physically balanced within its own vibration profile using the solution given. The dramatic

immediate results our system is demonstrating in harsh operational environments when operated only by soldiers is providing the Army with a key technology enabler that is transforming the way maintenance is done today. I believe CDB emphasizes the importance of the


dynamics of the whole drive train, and the interaction between its inter- dependent parts, rather than isolating by analyzing the drive train by specific components. CDB is concerned with a holistic approach, rather than the analysis of separate components. The CDB technology 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. This Preventive Maintenance process keeps the vibration deteri- oration rate very low and moves component lifetime closer
