I ve seen many references and discussions about lube oil being aerated by a turbo. Many use de aerator plates or other means in an attempt to separate the air from the oil. I can't find any reference to a de aerator system in a normal turbo charged engine , while I m pretty sure that the oil returning to the engine sump must also be foamy.
Does anyone know about a de aerator system on a piston engine ? If so could this be adapted to DIY jet engine ?
I ve seen some commercial centrifugal de aerator but those seem to work with pressurized oil. That s unusable on an oil return line.
Real jet engines use mechanically actuated centrifugal air oil separators of uncritical use to us. Maybe one could be built and electricaly driven..

Hi Richard A nice little Paper that might shed some light core.ac.uk/download/pdf/4403473.pdf :-) De-aerators are used on dry sump engines , a swirl pot at the oil tank return helps. We tend to run severely undersized oil capacities with our engines , a decent sized truck turbo normally has several gallons in the sump Cheers John
