Has anyone considered a turbine? In my search for a powerplant, I am
looking at the pros and cons. I noticed the ATP Turbine seems like a
great fit. I looked at the website, but it seems as if it hasn't
been updated in a while. I also ran across an email about it:
The fuel flows seem spectacular. I'm just wondering why I haven't
heard more about it.
Any Comments??
Hello! Thank you for your request of information on the ATP 6.5
Turbine
Engine. The following is some generalized information on the 6.5.
Weight 185 lbs
Length 32'' overall to prop flange
Diameter 12 1/2" maximum located at the hot section
10" diameter of gearbox
Height 16" overall located at accessory pad on gearbox
Burns JetA, Kerosene, Diesel and Gasoline
The preferred fuels are JetA and Kerosene
Four point conical mount
20 to 1 double planetary gearbox
Gearbox designed for 500 hp continuous 600 hp peak
Example ( If turbine is turning 60,000 rpm prop turning 3000 rpm)
Single stage radial flow turbine centrifugal compressor
Electronic fuel injection
Electronic ignition
120hp 10.7 gals/hr 300 lbs thrust at 2650 rpm
180hp 13.3 gals/hr 450lbs thrust at 2750 rpm
240hp 16.6 gals/hr 600lbs thrust at 3000rpm
maximum rpm at propeller 3200 rpm
usable rpm range in fight 2500 to 3200 rpm
Designed to operate efficiently at variable rpm
The intro introductory price for the 6.5 Turbine engine is $23,000.00
(engine only). In order to hold this price you must first put down a
deposit of 25%. We will soon be recommending the most efficient
propeller.
Production for the 6.5 starts Jan. 2002. We are also going to be
debuting a
pusher at Oshkosh 2002!!Thanks for interest in ATP if you are in need
of
further information please feel free to email or call. You can visit

It's mostly vaporware. Hasn't taken the world by storm by any means. Most
turbine folks in-the-know have said the fuel flows are way off base.
Turbines suck down fuel....lots of it. Turbines in small aircraft tend to
reduce their legs due to available fuel on board vs. fuel flow rate.
I'd love to have a truly affordable turbine too, but it just doesn't seem to
be in the cards yet. Someday, sure, but not in the next few years when I'll
be looking for an engine.

Don't hold your breath on this one! I talked to them
3 years ago about a FWF package for an RV. Said it
would be out by the end of the year.
Still waiting on that phone call, website update, or
something. Also, the fuel flow numbers have got to be
off, from everything I have heard or seen.
It's exiting technology. I hope they do well with it.
As Brian said, I think it will be a little to long
before they have a flight article that would be RV-10
worthy in the next 5 years or so. More power to them
if they can do it, though. I'd be happy with 300 HP
and 20 GPH if they could make it work. Our Bell 206's
are 317 HP and burn about 25 GPH on a good day, so I
think 300 shouldn't be too different.

Chuck Nearhfoof is the guru there at ATP, great guy and has roots here in
Lewistown MT. I don't think the ATP has enough zip to fit in the -10,
perhaps he will adapt it with more harnesses.
There is another turbine I was looking at was developed by and is
currently being manufactured by Adventura (SP?)(yes the ultralight) that has
the power. Worth looking into. But I just settled for a Lycoming IO-540 at
the normal Lycoming price :>( Maybe my next RV-10 or so, I can get more
serious about major changes in Van's way of thinking, but for now I like it
just fine. Call me chicken!

Thanks for all the info. If it sounds too good to be true, it
probably is.
As for fuel flow, I also find it hard to believe. I only have
experience with a slighty larger Garrett TPE331 that put out about
800shp and a bit more with water meth. That thing would burn about
400lbs/hr at cruise. It's also a direct drive engine. I also flew
the Saab340 for a while, but it's not direct drive. The fuel economy
was a bit better though. 600lbs/hr at cruise on an 1800shp engine.
Although not an apples to apples comparison because I don't know what
HP each was putting out at those fuel flows. They were both at
approximately the same torque settings and RPM which should equate to
the same HP.
Either way, I'll keep looking at engines. I really like the design
of the DynaCam engine, but it also seems like a vaporware product.
I'll probably end up with a Lyc. But it sure is fun exploring the
technologies available... or almost available.

Yes it is! It's also stessful! With the investment involved in these
things, it's about as tough a decision as financing a house. I recall what
a brand new, four bedroom home in a very nice part of town here in
Albuquerque cost in the early 70's....and I'll probably pay more for the
engine for my RV10. Of course, that house is now worth 5 times it original
cost!
For me, it's a Subie six banger with turbo or a *cough, wheeze, gasp*
Lycosaur. I've lived with a four banger O-360 on my -8 for four years now
and although it gets the job done, it's a pain in the ass to maintain.

Steve,
don't forget to have a look at the Crossflow 6cyl. fwf package. Although my
next airplane is not going to be an RV10 but a Four Winds 210, the people
from Four Winds met with the people from Crossflow. Four Winds' president
Jeff Rahm was extremely pleased with quality of the multiple fwf packages
and the competency of the Crossflow team. If you are looking for high
output, high quality engineering and refinement Subaru conversions,
Crossflow should be on your map.
Just my 2 cents.
Regards,
Placido
