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.
Thanks, Jerry
Paul, your e-mail is screwed up. I did not send any attachments with
the above message. Obviously the photos have nothing to do with oil
pans. Jerry
Yes it was. Should have gone out with another message. Sombody did
not get them the first time and wanted me to send them again.
Sorry.
