Reducing engine oil usage in aircraft is a major concern to the aeronautics industry. Although aircraft gas turbines have evolved tremendously in recent years, the lubrication systems have remained largely unchanged. Lubricants are used in aero-engines to reduce friction and wear as well as for cooling and sealing. To meet needs such as a lower oil usage, while keeping reliability and reduced mass, novel technologies are needed. A new Pump And Separation System integrates three critical functions of the aero-engine into a single system. They're the de-oiling and deaeration of the oil-air mixture produced in the engine bearing and the gearbox sumps because well as oil pumping right back toward the oil tank. De-oiling helps remove tiny oil droplets from the atmosphere ﬂow. Poor de-oiling performance implies high engine oil consumption that limits ﬂight stamina and increases oil tank fat and size as well as aircraft emissions. The deaeration function of the scavenge oil removes air bubbles from the oil-atmosphere mixture coming back to the tank. Bad deaeration efficiency raises problems with cooling and lubrication of the engine roller bearings. Undertaking partners have additionally successfully created and tested a method that's based on radioactive traces to measure an extremely tiny motor oil consumption. A newly created atmosphere blower positioned at the pump system socket guarantees sealing of the engine bearing chambers and efficient air suction through the whole atmosphere-oil separation system. Usage of the pump system will substantially simplify the aero-engine lubrication system. The reduction in number of elements will lead to a much lighter and more dependable engine oil system. The innovation could also result in much more efficient aero-engines that eat less oil and gas – a boon for the aeronautics industry and the environment.
