Vibration signal conditioningKeywords: Vibro-Meter, BFGoodrich, Sikorsky
Another Meggitt company, Vibro-Meter, informs us that it will supply state-of-the-art vibration signal conditioning to BFGoodrich and accelerometers to Sikorsky, as part of the BFGoodrich IMD-HUMS system selected for the S-92 aircraft. Vibro-Meter teamed with BFGoodrich in 1995 to supply the vibration monitoring electronics and sensors critical to the diagnostic algorithms necessary for the UM-HUMS system performance. BFGoodrich and Sikorsky recently completed an agreement which has made the IMD-HUMS standard equipment on the S-92.
The IMD-HUMS, includes an on-board component which gathers and processes data on aircraft usage and the condition of engine and drive train components. The information from the on-board system can be displayed to the crew and is routinely transferred to a ground-based computer, which generates summaries of operations, forecasts maintenance requirements, and supports rapid troubleshooting.
The IMD-HUMS is also being deployed by the US Marine Corps on the Sikorsky CH-53E Super Stallion and by the US Navy on the Sikorsky SH-60 Seahawk family. It is currently being evaluated for deployment on the US Army's Sikorsky Black Hawk family.
The first S-92 integration unit has already been delivered and will be supporting the development and certification flight tests that are expected to culminate in a Type Certificate for the aircraft and a Supplemental Type Certificate for the IMD-HUMS in early 2002. The IMD-HUMS is being certified in accordance with the FAA Advisory Circular on HUMS, AC 27-1 and AC 29-2. The IMD-HUMS will reportedly be the first HUMS system to be certified in accordance with these new standards.
