We are working on an expansion tank design and wondered if someone could share the important elements of a good cooling system design. Looking at photos of other aircraft I’ve seen lines to expansion tanks from A. Rear iron port. B. Radiator tank top. etc. A. Is height of tank significant? B. Volume required? C. How much air should be left in the tank? D. Cap style?. >>>> >>>> So much appreciate having this list. >>>> >>>> >>>> Steve Izett >>>> Perth Western Australia >>> I failed to answer several questions. >>> 1. 'Chocolate milk' looking oil does sound like coolant contamination (my experience was with a piston engine 40 yrs ago). You can add a schrader valve (tire valve) and pressure gauge to the coolant system, pressurize with air on top of your coolant up to your cap limit, and wait a day to see if it's losing pressure. (It will fluctuate slightly with ambient temperature, if there's much air in the system.) >>> >>> 2. There was a video, but I don't have one. >>> >>> 3B: Most automotive swirl pots I've looked at are between 1 & 2 quarts (sorry for the archaic measure; I live in the USA...). I've got several from different salvage yard cars (all with ~20 lb caps) that I collected to see if any would work on my installation. Upside is, most are translucent, making coolant level checks a lot more convenient. :-) >>> >>> 3D: See previous emails. A lot of guys use ~20 pound caps. This is higher than older automotive systems (most were ~14 lbs), but fairly common on newer cars with pressurized swirl pot style systems. Higher cap pressures are supposed to help prevent unneeded venting of coolant at altitude, where ambient pressure is lower & will effectively lower the pressure point (cap pressure is the difference between system and ambient). >>> >>> Charlie >>> >>> -- >>> Homepage: http://www.flyrotary.com/ >>> Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html >> >> -- >> Homepage: http://www.flyrotary.com/ >> Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html > > > -- > Homepage: http://www.flyrotary.com/ > Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html
