Aircraft Engines Rely on Eaton's Oil-Debris Monitoring Technology for Optimal Health and Performance

Date: 6/19/2017


PARIS AIR SHOW, June 2017 — As a pioneer in the field of engine prognostics, Eaton manufactures debris-monitoring products for the aerospace industry's major gas-turbine engines. Eaton introduced a technology that continues driving improvements in safety, reliability, fuel efficiency and lifecycle cost for commercial and military aircraft engines.

Eaton's technology is also setting the stage for aerospace engines of the future. As engine manufacturers incorporate more lightweight alternatives to steel, such as ceramic hybrid bearings, Eaton is developing advanced sensor technology that can detect ferrous, non-ferrous and non-metallic materials. In addition, Eaton is applying advancements in additive manufacturing to support R&D for improved debris-monitoring and oil-quality sensors.

Eaton's oil debris-monitoring systems enhance engine health and aircraft safety by capturing and retaining oil debris particles for analysis to determine if critical engine component failures are imminent. The technology has evolved along with the aerospace industry's demand for lighter, more fuel-efficient aircraft. Eaton led efforts to develop low-pressure debris-monitoring systems that use less energy, operate more efficiently and improve fuel economy and reliability. 

Eaton's oil-debris monitoring system incorporates a patented Lubriclone debris separator, a quantitative debris monitor (QDM®) sensor and a signal conditioner. QDM is a proven, mature technology that has produced significant gains for engine monitoring and aircraft maintenance while improving safety and reliability and lowering operating costs.

Eaton's technology also saves money by reducing the maintenance burden for airplanes. Engines equipped with oil-debris monitoring systems preclude the need for manual checks and inspections and enable condition-based maintenance, a more cost-effective alternative that increases time on wing over the life of the airplane. Likewise, oil-quality sensors can detect issues such as oil degradation and seal failures in early stages so operators can take action to prevent engine damage.
