Paul,

Getting closer to making our own rotor housings so I finally had to get my inner surface corrected to be an actual parallel trochoid surface. This model has all the math correct including the corrections for angle of oscillation on the apex seal. Feel free to share this info. Comes out, my original model based on CMM data was very close.

That is great news  Larry. There are big bucks in rotor housing as Mazda charges $800 bucks for new rotor housings.

Consider making simplified AL end housing as there is a market for light weight single rotor engines in OZ, NZ and LSA aircraft in the US.

You don't need oil pumps as external dry sump units will work.
Same goes for side ports as P-port are the way to go for aircraft use.

We also need Ford and Alison based gear boxes. You are in a good position to supply all the parts needed to make rotary aircraft engines.

Hopefully the aviation economy will pick up after the election.

Here are some pictures taken a few years ago of Larry's NC shop and the Reno unlimited racer Larry crews on.

Larry happend to have a spare Tracy gear box when Dave Leonard sized his gear box at Reno. Somebody flew back to Ca and picked it up. We had Dave Leonard back in the air in 5 or 6  hours.

Nice setup, clean shop, etc.
We need a set of drawings for a 3.12 box, 250 hp, to price it out with an engine aluminum center plate, automatic bellhousing, etc. Pusher design.

The folks with home  I converse prefer the automatic xtrans bell housing putting the starter facing forward on the pusher design, to move the CG forward, etc.

Do you have Rhino or Solid Works Milo?
