Thanks you Gentlemen,
I will get the CAD drawing done from one these CAD freelancers on the
net and post back the results. . Just one question - which of the three
SAE 1,2,3 will go with the FORD transmission parts from slausons ?
Regards Zahid Rahman
I saw this photo o various Ford planetary gears on the website, how does
each one effect the reduction ratios
The planet carriere with the square theet is 3.12 and the other is 2.85.
Hold the ring gear in both cases. The flange # goes with any gear box.
The big flanges are for wood props.
Paul Lamar hold off on the email. I'll be back in a few days.
You said the planet carrier with teeth is 3.12 and the other is 2.85.
I was looking at this gear box
http://www.aeromomentum.com/gearbox.html he described the ratio of his
gearbox 2:5:1 Designed for 4 cylinder engine up to 210LB horse power. In
terms of horse power if that is the correct way to view the ratios what
horsepower should be used with 2.85 and 3.12

Any HP number.
Here is a little quiz. If I have an engine that generates 200 HP at
6000 RPM what is the torque?

Paul,
What stands between the status quo and a certified engine, if it is
crystal clear that rotary is the way to go?

In order to stay in business a company must make a profit. Lycoming
stated that when the vast majority of customers demand a Wankel engine
Lycoming would build it. Lycoming would have to build a factory to make
Wankel engines because the FAA demands a paper trail from the mine to
the air. This FAA policy hampers innovation. Mazda estimates over a
billion dollars to build a new Wankel engine factory so they keep the
one they have.
Lycoming would then be out of the experimental market which is about
20 to 30% of the total market for light aircraft engines. Since a used
Mazda rotary engine is near free Lycoming probably could not make money
for years to come. Your tax dollars at work.
I think Mazda should get in the aircraft engine business to better
utilize their assets but it would be a drop in the bucket to 100,000 car
engines per year. I would do it for PR reasons.

Greetings Gentlemen,
I am quiet concerned about the ending of Mazda rotary production and
would like to see the Mistrel type av engine fitted with a compound
turbo system as per Pauls' CAD drawings. Nothing short of brilliant!
We have just finished price negotiations on a Seawind 3000 incomplete
amphibian kit which we expect to take delivery of next month. We will be
installing a 20b Mazda on it with a compound turbo system. Yet to be
engineered. Quality reference from anyone having the needed knowledge in
turbine sizing/design would be highly appreciated.
All the manifolding/mountings will be scratch made in house. We have
located blade producers to handle blade assemblies.
I grew up in a family run machine shop and have 25 years as a Plant
Engineering Technician.
Efforts are now moving forward on obtaining ample funding for an
additive machining center to produce honey combed interior shaft
assemblies and end covers to further reduce weight and bring production
costs down.
100 pounds of Monel reduced to 27 pounds of shaft leaves a lot of time
and material on the floor!
We also have a huge existing residential market use for an affordable 45
hp rotary with a blow down turbo. Which we will not disclose for
engineering with out an NDA. $5,000 for an Axiro is more than a bit much!
Cheers Ya-All,
Michael Nash
Michael,
A word of warning on the seawind, they are a real dog to fly.
Having that engine up there on the tail is a bad idea, they suffer badly
from gyroscopic precession when rolling into the turn. A good friend of
mine here killed himself trying to take off from a lake, he hit a boat
wake (not a big one) and it porpoised and dove in killing him. They can
only handle a very small choppiness on the water. I flew it a few times
and boy did it need a lot of rudder input to co-ordinate in a turn.
Changing power settings on final for landing was a disaster, the pitch
changed dramatically with throttle change. Just my 2 cents worth here
Michael.
Chris in NZ.
With the CG that high I can see how that might happen. Any significant
impact at water level will
cause a pitch down.
