The Renesis oil pan is very different from the 13B oil pan. It is of course much shallower and it has a number of baffles in the bottom of the pan that I think are intended to separate oil from oil foam. Neither oil pan uses a windage tray in the stock application.

The wedge oil pan that we are proposing for the aircraft rotary engine may be improved similarly by the use of baffles or maybe not. That is a question I would like the engineers on this list to comment on. Also, for aircraft use, the windage tray might be of value in steep climbs or descends.

I do think we need to revisit the shape of the wedge tank. Consider two aircraft one a tractor and one a pusher with identical wedge oil pans. In a hard climb, the pick up may be uncovered in the pusher. The remedy may be to make a double wedge with the greatest depth at the pick up. This design can still be made to fit the wedge plenum. However, it will sacrifice some of the space under the engine when compared to the full wedge. Or perhaps the wedge can be turned around for the pusher. Another issue with the doujble wedge is that at the bottom of the inverted apex of the tank, the tank needs to flatten for a couple of inches so that the pick up screen does not impact on the tank walls. Whatever the design, it has to fit the pick up tube and screen obviously. In the single wedge, this may be even a greater issue.

I am interested in making some new wedge tanks for both the 13B and the Renesis if we can come up with a universal design for tractors and pushers or even if we have specific designs depending on tractor or pusher.
