Paul,

Seems like I remember a couple of South American
brothers had
something along those lines that was featured a few
of years back in
one of the aero magazines

There was just such an installation in a very ugly car
at SevenStock a couple yrs ago. It did couple the
engines but I don't know if it provided reduction. You
must have seen it Paul; I know Robin did. I'm sure it
was one off made by the fellow showing the car. And I
can only suggest contacting the show organizer to get
a lead.

regards, Robert

Yes I remember that car.

Yes, there was (and possibly still is) a company with a reduction that
couples two rotaries.  It was produced by Wankel Rotary GmbH and was known
as the "Twinpack".  Testing began in Germany in June 1996.  It used two
70-hp rotaries next to each other with a center-mounted reduction drive for
a single propeller.  Published overall dimensions were:  height 17 in; width
25 in, length 28 inches.  Overall weight was 262 lbs.  each engine was
claimed to produce 70 hp (51.5 kW) @ 6000 rpm.  Coupled they produced 140 hp
with a 1.3:1 output reduction via a belt drive.  Static tests of the engines
were claimed to have demonstrated the ability to run on Jet A fuel and
hydrogen.  The contact information in my files is:  Wankel Rotary Gmbh,
Jahnstrasse 1, D-71404 Korb, Germany.  Tel:  07151-300432, Fax: 07151-33067.
Haven't heard of this outfit for some time.
good luck.  GW

Pretty much vapor ware George. I was at the factory in Korf Germany
and there was no sign of it. I never saw one at their booth
in OSH either. They are now bankrupt as far as I can tell.
I was good friends with the ex president Juergen Bax but I have
not heard from in in years.

The web site is still up but there is nobody home.
