Gordon.
The P-port is in the coolest part of the rotor
housing. In fact Mazda attempts to heat that part of the
housing to keep the engine from distorting into a banana
shape.
That is why the coolant goes in the hot side first and
than comes around the cool side and thence to the rad.
It is called axial flow cooling. Widely used on almost
all car engines.
It is also not perfect as the rear rotor gets hotter
than the front rotor. That is also why you will always
have problems with the rear rotor first.
Everett Hatch attempted to address this issue by
feeding cool water into the center housing and have it divide
into a front and rear flows. This is called parallel
cooling and is used on most liquid cooled aircraft engines.
Max Bentele patented it for CW.
Also NSU used parallel cooling on the RO80 engine.
Orenda also modified the big block Chevy to parallel
cooling when they attempted to convert it into a
liquid cooled aircraft engine.

paul,
i thought you might be interested to know, the orenda
engine has been sold to a new company in midland texas
and is finaly going into production. here's a local
newspaper article. p.s. i live in midland and my mom
used to deliver mail to jim hall's shop before she
retired.

Airplane engine firm to hire 114, workers train at
Midland College
By: Bob Campbell
Two years of negotiating with a Canadian corporation
and a year of raising money have paid off with the
opening of a global airplane engine company between
Midland and Odessa.
Working in concert with Midland College's aviation
technology program, West Texas Energy Technology
Initiative on Tuesday said TRACE Engines will
exclusively make and market 600-horsepower Orenda
engines to power business aircraft and utility
airplanes like cropdusters.
Certifications, patents and 14 tractor-trailer rigs
full of equipment were secured from Orenda Recip of
Toronto, Ontario, Canada, and TRACE bought the former
T&P trailer manufacturing building and 22 acres at
3000 W. Interstate 20, just west of the Midland County
Horseshoe.
Five trucks from Canada will unload there by the end
of this week and a 62,000-pound test cell will be
laboriously transported.
Noting employees will earn $16-$25 an hour after
training at MC, WTETI Executive Director Stephanie
Sparkman said, "TRACE will recruit and train young men
and women from throughout the Permian Basin and
provide them with high paying jobs.
"The visibility of this program will serve as an
incubator for our region to win additional
manufacturing activity."
TRACE Engine's incentives from the Texas Enterprise
Fund and Midland Development Corp. call for at least
114 jobs to be established within three years. "We'll
be pushing product out of the T&P building within a
month after the Federal Aviation Administration
certifies the facility," a WTETI spokesman said
Tuesday afternoon.
Noting the enterprise fund allocated TRACE $456,000 in
May, he said MDC is considering a similar amount.
Texas House Speaker Tom Craddick of Midland said Gov.
Rick Perry, Lt. Gov. David Dewhurst and he were
interested because the project will diversify the
Basin's economy and be outside the state's major
population centers.
Interviewed Tuesday afternoon in Midland, he said the
quality of jobs was also persuasive. "We'd like to see
businesses spread all across the state, not just to
the two or three metro areas," Craddick said.
"We're elated to have this, particularly considering
the job training will be at Midland College, which is
one of our treasures. There is a lot of local money
going into it and we'll take all the companies Canada
wants to send us."
MC's aviation technology director is Dennis Givens.
The $20 million plant will sell its 740-pound engines
for about $150,000 each, capitalizing on a market
currently dominated by turbine engines that are less
efficient and less powerful at cruising altitude. The
largely aluminum Orenda - Iriquois for "power" - 495
cubic inch V-8 features maximum crankshaft speed of
4,400 rpm and an 8:1 compression ratio.
It has been successfully tested in aircraft including
the Air Tractor 300 and 400 Series, De Havilland DHC-2
Beaver and DHC-3 Otter, King Air C90, Aero Commander,
Turkish ZIU, Explorer 500R, LZ-410, Hongdu N5-A 600
and Russian Rhino, according to company literature.
Another reputed advantage is the air intake will not
aspirate agricultural spray, water vapor or debris.
The Orenda's chief competitor, the Pratt-Whitney
PT6-21 turboprop, costs $400,000.
Attorney Curtis Leonard said 30 equity investors
primarily from Midland and Odessa "have successfully
completed the purchase of all technology rights,
manufacturing equipment, FAA, Transport Canada and
European aviation certifications and all worldwide
manufacturing and sales rights."
He reported introducing the program two years ago to
WTETI and three of its founding members, including
Craig Campbell.
Other key men are Chief Operating Officer Milan
Matusik, whose Milan Aviation Co. makes Rhino
cropdusters in Konovice, Czech Republic, and Calgary,
Alberta, Canada; Vice President Derek Parker, who will
head sales after working with Orenda Recip in Toronto;
and native Midlander Craig Hoover, an aeronautical
engineer-business executive moving from Fort Worth as
a "CEO in training."
Orenda Recip in Toronto will now concentrate on
producing helicopter engines and no longer manufacture
the liquid cooled reciprocating Orenda engines to be
made here, the WTETI spokesman said.
He said the People's Republic of China is a promising
customer with Li Fei of Hongdu Aviation Industry Group
having told TRACE 2,500 to 5,000 engines are needed
there.
Parker said the Orenda "is applicable to 40,000
potential worldwide retrofit aircraft applications
where no feasible alternative exists. It offers a more
fuel efficient alternative that is easier and less
expensive to maintain and can cut operators' costs by
as much as 35 to 50 percent," he said.

Thanks for the info Gary. I thought it was dead forever.
Total investment is now up to 50 million Canadian and 20 million
US. I wonder if Jim Hall has any money in this.
