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 ?

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.

How? :-)

I used the calculation Torque = Hp X RPM divided 5252. However I
have had a different answer from an on line calculator, If I use Hp X
33000 Divided by 2pi then I get 171.15. With the Rotax 503 now out of
production the need for a rotary of between 45-65 Hp would fill the
needs for many microlight aircraft, especially if the cost can be
kept at a reasonable level. Andrew.  Campbell




Now there's your problem.

The equation for HP is:

(Torque * RPM)/5252 = HP

If you transform that equation to solve for Torque:

(HP * 5252)/RPM = Torque

(200 * 5252)/6000 = 175
