FAG Aerospace breaks four-million speed parameter barrier for engine bearings
Technological leap towards more efficient aircraft engines
FAG Aerospace, a member of the Schaeffler Group, has developed a new aircraft engine ball bearing that redefines the performance limits for high-speed bearing supports in main shafts. As part of the collaborative project Effective Oil System , conducted under the Aviation Research Program (LuFo) funded by the Federal Ministry for Economic Affairs and Energy, FAG Aerospace has broken new ground by designing an engine bearing that for the first time exceeds the speed parameter of four million millimeters per minute und uses only minimal cooling oil quantities. The new bearing represents a significant technological leap in the development of more efficient engines and could reduce the consumption of the world's passenger aircraft fleet by up to 200,000 tons of fuel annually.
The newly developed ball bearing has been validated on a Schaeffler test stand where the testing program requirements, i.e. the simulated flight cycle, were coordinated in close collaboration with the project partner MTU Aero Engines.
The new cooling design enables a specific adjustment of the maximum permissible ring temperatures using the same oil quantities as for conventional bearings. This means that almost 70 percent higher speed parameters are achieved with identical bearing temperatures and oil quantities, so that current materials and cooling oils can be used despite higher circumferential speeds. In turn, if the speed parameters remain the same and smaller quantities of cooling oil are used, then the bearing temperatures will be up to 25 degrees Celsius lower and power losses reduced by up to 25 percent. All this adds up to increased efficiency and reliability of the bearing support.
The new aircraft engine bearing also features integrated oil damping of vibration loads. In addition, the performance-enhanced duplex hardened raceways provide greater robustness, strength and wear resistance, while reducing the rolling contact loads at the same time. The higher efficiency and reliability of the new ball bearing is also due to direct cooling of the outer ring and the ceramic balls that help to reduce friction and weight.Bearings in aerospace applications need to work with the utmost reliability even under the most critical operating conditions. These days, in the initial phase during take-off, speed parameters of up 2.4 million millimeters per minute are achieved with the engine bearing investigated. However, to meet the future requirements of airlines as well as the constraints imposed by environmental and climate protection legislation, further improvements will be necessary with regard to the mechanical and thermal efficiency of aircraft engines over the next 20 years. As a consequence, enhanced speed and thermal load capabilities will be required for the bearings. And this calls for innovative materials, cooling concepts, manufacturing and heat treatment procedures, as well as advanced calculation and simulation methods.
