I am also very interested in any PSRU design
good or bad.
You never know what small piece of information
you can glean from others ideas
Hi
Bernie, I used to have a Ford V6 with a Blanton Drive – there was no TV damper
built into the 2:1 ratio drive.
Near
the end of my V6 days I contacted a guy in British Columbia (Mike Hirshfield)
about his V6 installation which was very successful – he was flying
exclusively on floats and had a NOS system which boosted his rpm to 4800 on
take-off – he claimed better performance than Cessna’s with 0-470’s. Anyway he
had a set of drawings for his reduction drive – I couldn’t make sense of them
– he said if I took them to any machine shop they would be able to make the
necessary parts.
If
you’re interested, I’ll dig them out and try to get you a
copy.

Interested in cog-belt PRSUs?
To George ( down
under) and others interested in cog-belt PRSUs:
(Bernie: "George,
you're upside down!" George: "No, no, YOU'RE upside down!! I can see perfectly
well that I and other people, and houses, and telephone poles, and dogs are
upright! SO THERE!!"
Here endeth the silly stuff.
George, you wrote "Ask about weight, type of torsional vibration
DAMPER, density of Damper, tracking adjustment, density of engine mount
rubbers, and HP limits". Which rotary model should they focus on, like the
13B, 13B Turbo, the Renesis, 20B as having the potentially greatest demand?
Same for potential demand for"normal vertical" engine orientation or "Plugs
Up". They will have to expect a potential market for the effort in
designing and making one or maybe 2 versions of a belt PSRU for the Rotary.
You other guys, please join in with questions that should be asked, or
other strategy points. I don't want to make this inquiry without ducks
aligned. Have you ever made a technical inquiry and you were ignored? It's
happened to me, and I was angry and frustrated, worst of all, I was not being
taken seriously and I did not get the needed information.
Let's hear
from you. For those that have missed the beginning of this, it's about the
first Cog Belt PSRU that I have seen with a torsional vibration damper instead
of the driver pulley mounted straight on the flywheel. George found them in
Brazil and sent the web addresses to me. The site is in Portugese only (except
the numbers are in English - yuck yuck). We want to know a little more about
their PSRU, and if they could be interested in trying out for a Rotary PSRU.
We're basically asking them to spend a lot of money, engage in a lot of effort
and sweat, and it's all a big risk for them:

Thanks, Bernie.
