Robust filtration improves helicopters: Reliability & safety

K. Suri*, M. Gao, M. Sandford, B. Mouhebaty, PTI Technologies, Inc, USA

Particulate contamination is one of the main sources of failure in a helicopter hydraulic system which may result in high risks, both in human life and financial cost if failure occurs during mission critical flight conditions. Hydraulic systems have to encounter wear and tear of components and contaminants generated by the system. Fortunately, induced failures can be minimized if appropriate contamination control strategies are applied during design and maintenance activities.

Improved filters with robust design were installed in few AH-64 Apache and UH-64 Black Hawk helicopters. Monthly oil samples were taken to monitor fluid cleanliness and logged from each of these helicopters. After over 30, 000 flight hours, data showed that Mean Time Between Failure (MTBF) of key components was dramatically increased. This resulted in savings of several hundred dollars per helicopter flight hour, thus reducing over millions dollars....
