Paul It seems to me this engine set up is more or less what Tracy
did with his RV The throttle body is a cut down of the standard RX 7
, and the primary throttle plate and barrel removed ,if i am not
mistaken.
In such a set up A What type of rpm can you develop if you use the
3.1 redrive planet and prop say for the falconair f12 in the photo B
The dynamic plenum volume i believe , must be 2,7 more than the
volume of the intake runners ,is this correct? C Would it be better
if the primary intakes (smaller diameter intakes) would be on its own
throttle plate and chamber in the intake plenum and not been removed
in the throttle body If you can help me on this thanks
Le Roux Breytenbach
Depends on the pitch and the diameter. Mainly the diameter is limited
by the tips going transonic.
That plenum is a joke. It enhances the torque at 3000 RPM absolutely
where you don't need it :-) I explained that to people many many
times and they still did it anyway :-) I don't think Tracy ever
understood it. Certainly not when he used it for the first time.
Mazda did it because cars need low RPM torque for good acceleration
in first gear. Mazda called it a dynamic chamber.
Airplanes fly on HP and HP is RPM times torque. The more RPM and the
more HIGH RPM torque the more HP.
You want max torque to happen at 6000 RPM or above. A simple runner
18 to 20 inches long will give that with a p-port. You will get more
HP with out the dynamic chamber.
If Mazda uses the 16B in the new car it is a partial answer to the
car low RPM torque problem. Torque is mostly related to engine
displacement. The 13B is a small engine for cars or airplane engines.
It 160 cubic inches while the typical light aircraft engine is 320
cubic inches. The 16B will be about 200 cubic inches if they make
it.
The torque peak in my New Dodge (Fiat) stealth motor home MB engine
is at 2000 RPM. While I am at it I will mention the transmission is a
computer controlled six speed conventional manual transmission. The
computer throws the clutch out and shifts it with small hydraulic
cylinders. Just like a Formula 1 engine :-)

In 18 years of the newsletter there have been several situations
like this.
Some one comes up with something that appears at first glance to be
an improvement. Someone else analyzes it and discovers draw backs or
it is simply undesirable for the new application. It might work in
other applications.
The first person lets his ego take over and refuses to under stand
or learn what the second person is saying.
In one case a new newsletter was formed by the angry first party :-)
To learn you must have an open mind and keep your ego in check :-)
Try to understand why the second party is saying that or just ask
him why do you think that?
Paul Lamar
Hi Paul,
I appreciate and have learned much within this group for sure. !!!
I think we are all in debt to yourself and others who have pioneered
a path in aviation with the rotary. When I was building back in the
late 80's and 90's, the Tracy's and David Atkins types...Lou
Ross..etc. were who were out there and available. Though it could be
said that there is no loss out here as to egos :) , they were a
contribution to where things are today.
Despite the Tracy and David's not getting it right ( plenum's being a
joke) they both continue to fly all over the continent on those so
called... jokes. Yes, a few us followed them in, but.. your
enlightenment to a better alternative doesn't diminish their success.
So until we are all flying on your yet to be produced ignition and
other components.. Thank you for continuing to help evolve where the
rotary movement can be in the future of our personal flying
machines.
Thanks,
bruce buksyk
Speaking of the ignition the patent I applied for was a real up
hill battle.
The first patent attorney I hired, despite having a degree in
electronic
engineering, was not competent in that field. I had to fire him
and find
another. The second called himself the patent king. He did a good
patent
but then he dropped the ball. The patent office rejected it due to
minor
drawing issues and name discrepancy by leaving out my middle name on
some of the forms but not others.
The patent office has a policy of only notifying the attorney that has
power of attorney and not the inventor. This happened in April 2015.
The patent king did nothing and did not notify me. Simple problems
to fix.
I was under the mistaken impression that every thing was OK and the
patent
office was doing their thing. Finally I got worried and called the
patent office.
They confirmed that the patent was filled but since I did not have
power of attorney they could not tell me anything about it despite
being
the inventor of record. I had to file a form to make myself the
attorney.
I fixed the minor problems and the patent office revived the patent
application. A year and a half lost. Still the original date of the
patent
application applies.
I have a patent on programing computers that was manufactured
by Hewlett Packard without my consent. I won the case but again the
patent attorney
defending me did not do a very good job on net monetary compensation to
me. It
is essential that one obtains an injunction on manufacturing
immediately.
One is very vulnerable to incompetent or scam artist patent attorneys.
My advice is get some how too books and learn how to do it your
self.
Paul Lamar
I think the single person that did more to promote the rotary and
continues
to promote the rotary than anyone else is Dave Leonard. He now has
over 600
hours. One of the things he does is fly in formation with at least 50
other RV's
for major sporting events. He also participated at Reno. Unfortunately
the race was
canceled due to the P51 fatal.
Thank you Dave!

Getting a Patent on Your Own | Nolo.com
Here's how to get a U.S. patent on your idea or invention --without a
lawyer.
View on

Chapter 2 lists these quotes:
Don’t bury your invention:
“The man with a new idea is a crank – until the idea succeeds.”
Mark Twain,
“For an idea that does not at first seem insane, there is no hope.”
Albert Einstein
“Opportunities are seldom labeled.” John Shedd
Without inventors and inventions, we would still be living the way we
lived 50,000 years ago.
These books are also in libraries.
Rolf Pfeiffer
So true Rolf. Part of the requirements are the capitalistic form of
Government. The lure of making a lot of money on your ideas is
essential.
I can't think of anything useful having been invented in Russia.
The creative people like Sikorsky and Alexander P. de Seversky
left in
the 1920's.
"During the 1917 Revolution , Seversky was stationed in St. Petersburg
and remained in uniform at the request of the commander-in-chief of the
Baltic Fleet. In March 1918, he was selected as an assistant naval
attaché in the Russian Naval Aviation Mission to the United States.
Seversky departed via Siberia and while in the U.S., decided to remain
there rather than return to a Russia torn apart by the Revolution.
Settling in Manhattan, he briefly operated a restaurant."
He went on to design the P47 more or less. He applied for and was
granted several aviation patents.
Unless we turn this nation around the same thing will happen here.
Paul Lamar
Yes Paul,
Unless the present party is changed we will have to wait longer to
turn the nation around.
I hope we do better than Brasil where the crocks are back in charge
again, bypassing the people.
Don't keep the establishment here, it will only get worse.
Rolf Pfeiffer
Trump is not part of the establishment.
I talked to a young moron just out of collage and I asked him if he
had taken economics 101.
"No!! I am not into greed" he said. His professors brain washed him
into thinking economics
is greed.
Economics is part and parcel of life. Bad economic policy
separates people from happiness.
Not being able to sell an egg from your chicken to your neighbor is
stupid.
That was the law in Russia. The government handled all financial
transactions.
The Russian mafia was the Russian capitalist :-)
This is were the moron/liberal/Democrats want to take us. Almost 50%
of them voted for an avowed communist in the last Democrat primary
election.
We must also take back control of all the schools from the moron
liberals.
The vast majority of college professors never had a real job.
I would make a 20 year career in the economic system mandatory
qualification
to teach.
Paul Lamar
Rolf, you mean to say Ukraine is not the only country crooks have been
running. Well according to the Putlerstain trolls that is fact about
Ukraine.
As to Paul's statement about the education system needing reform; I
almost got arrested trying to talk a school board trustee into keeping
the ex step son back because he was only getting 40% in classes. He said
they felt failing kids (grade 5) was not good for their psyche. I told
him it was his fault young people go postal. Of course he denied any
responsibility. I explained it was directly his fault because what they
were doing always pushing kids through taught them whatever they did or
did not accomplish was acceptable. Then when they had to get a real job
and learn about failure as an adult it was not good for their psyche! I
suggested he should be one on trial next time a kid went postal.
