From decades of operating rotary wing aircraft, militaries, civil manufacturers and operators of helicopters around the world, have learned that one of the biggest enemies to sustained flight operations can be destructive harmonic resonant high frequency vibration (HRHFV). HRHFV is defined for trial purposes as the tendency of the drivetrain to mechanically. Such vibrations are caused by imbalances in the drivetrain, uneven friction, and the uneven meshing of gear teeth. Rotary wing operators worldwide have borne the costs of dynamic component failure due to damaging HRHFV, long before predicted time before overhaul (TBO). Eli Navon says “It has been observed that safety-related problems in various parts of the aircraft have arisen from HRHFV causes. Problems such cracked welds, cracked fuselages, loose wiring connections, and in-flight failure of dynamic components”.
Attempts within industry to address these problems have mostly focused on monitoring vibration data using different methods of analyzing data trends in an attempt to predict useful life of dynamic 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.
Shake’d Technologies, Incorporated have developed an innovative technology–Customized Dynamic Balancing (CDB)–that virtually eliminates the detrimental effects of vibration and harmonic resonance within the drive-train, aimed at reducing operating and support (O&S) costs while increasing aircraft availability, safety of flight and logistics supportability says Eli Navon.
Rotary wing aircraft are often plagued with dynamic component malfunctions within the drive train components.
The root cause of many of these issues can be traced to harmful vibration of the dynamic components; more specifically, harmonic resonant high frequency vibration (HRHFV). HRHFV causes an unplanned accelerated reduction of the airframes useful life thereby increasing operating and support (O&S) costs and decreasing both aircraft availability, safety of flight, and logistics supportability.
According to Eli Navon CDB is unique, newly developed technology that employs a complex proprietary set of algorithms aimed at eliminating destructive HRHFV. 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 drivetrain may be custom balanced, eliminating HRHFV. Each aircraft drivetrain is then physically balanced within its own vibration profile using the solution given. The dramatic 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
