Bobby,
It is amazing how much it costs to go faster. 50 hp costing 4-5 gal/hr is
only good for an additional 11 mph! 5 gallons to go 11 miles.that is
expensive!
I wish I had paid more attention to the drag on my bird! :>(
Weight helps in the climb. I probably was able to save 10 lbs of empty
weight building the plane over 7 years. I went on a diet and exercised a
little and lost 30 lbs over the last few months! I have been trying to
think of a way to bring this subject up with my wife..! :>)
On second thought, it climbs pretty well.
Bill

Using Van's climb performance numbers I'm closer to the 210HP engine than
the 230HP. Maybe 215HP net. The super charger mechanical losses may be as
high as 10HP and the air temperature rise could be another 10 HP. Water
injection cools the intake charge but displaces O2 so I really don't know.
I'm sure the gearbox has mechanical losses also. So 230-240 HP before
operational losses seems reasonable.

Wouldn't you think that equates to about 250 hp on take off??

Bill,
I believe my normal fuel flow is actually closer to 23gph at 7000 rpm\ 38"
MP and 12.5 FA. I don't really look at it anymore during takeoff. I'll pull
current engine logs when my AFS-3400 EM gets back from repair. It decided to
start rebooting every few minutes. I can run 40.5" MP / 7500 rpm at sea
level but avoid the top limits. My MT controller is within 100 rpm.

Bobby,
You can take my fuel burn numbers with a grain of salt. The EM-2 is not
completely calibrated for fuel flow.
By the way, is your prop controller dial calibrated to the prop rpm you
actually get? Mine is not and I think that Mark's may not be either based
on some of the things he has written.
To get 7100 engine rpm, which is 2500 prop rpm, I have to set the controller
for 2600 for takeoff. 2400 setting will get me 6500, etc.. Early on, I
thought that the tach on the EM-2 might be off, but I decided that to be
pretty unlikely. However, there is a disconnect between the two.

12 gal/hr for takeoff sounds extremely low. I'm closer to 25.
I leave the prop in automatic mode all the time. I set the prop to go
around rpm on downwind. 2300 / 6500 works well for me and almost eliminates
air breaking during short final. I try to carry a small amount of power
through the flare but I think that's common with RV's. I had to really work
on slowing down before entering the pattern and adjusting the prop to 2300.

Charlie,
I am flying a Lancair Legacy Fixed Gear. I burn 8.5 - 9 gal/hr at cruise
and a little over 12 on take off. I don't have my fuel flow calibration
completed and it could be part of a gallon or so off on the EM-2. I get over
20 mpg at over 185 mph which I still have trouble getting my head around!
In a car going that fast you would be measuring it in gallons/mile! I
really never tried to lean the engine before I put the broadband sensor in
the plane so I don't really know the answer about the egt spread. I do get
a lot higher egt readings than were advertised. I was expecting temps in
the 15-1600s, but they are in the 1700s.
Since the rotary is so sensitive to rpm for power output, I don't know if I
would have been happy with it with a fixed prop unless I had more power than
I needed. I have seen two MT props for sale since I bought mine and both
were good deals. I highly recommend the electric prop. It responds a
little slower than a hydraulic prop, but that is only a problem if you slam
the throttle. I guess the other con for the prop is it helps to carry some
power to touchdown because if you chop power in the flare, the prop goes
flat and acts like a big brake and the plane seems to just stop flying and
drop. I carry power, but I think Mark switches the prop to manual in the
pattern and lands it like it was a fixed prop. I don't know what Bobby does
in this case.

Hi Bill,
I'm always hungry for 'numbers' like that. Can you refresh my memory on
which plane you're flying?
What's your fuel flow during takeoff?
And I'm really interested in your fuel flow at your cruise setting of 6000
rpm full throttle up at 7500-8000 feet. Do you have an EGT in addition to
your f/a gauge? If so, what's the egt spread between peak and leaned to your
cruise setting of 16-1 f/a ratio (how many degrees lean of peak)?
Having a controllable prop certainly makes it easier to get a full set of
performance numbers, doesn't it?
Many thanks,
Charlie

Rich,
I am flying the NA Renesis with MT electric prop and wideband O2 sensor.
Take off and initial climb is WOT with 7100 rpm, after about 500 ft AGL, I
dial the prop back to 6500 rpm, still WOT. Cruise climb is WOT and 6000-6200
rpm, and cruise is WOT and 5200-5800 rpm. All climbs are at 12.0-12.5 F/A
mixture and cruise is 15.8-16.0 F/A mixture.
I never move the throttle off of wide open until I am slowing to enter the
pattern for landing. Engine speed is controlled with the prop and power to
some extent with the mixture.
I have hopes that after Bobby makes his decision as to whether to go with
the turbo or the 20B, he will give me the other one! :>)

Rich,
My normal, not in a hurry settings.
38" MP / 7000 rpm for takeoff and initial climb with F/A 12.5-12.0. Cruise
climb 5800 rpm 30-32" MP F/A 13.5- 12.5. Preferred cruise rpm 4800- 5200 At
less than 30" MP and F/A 15.8-16.0. Full throttle. Prop rpm controls engine
rpm and super charger bypass controls MP. A turbo charger and automotive
waste gate would likely require throttle management during high rpm
operations.

Greetings genlepeople of the rotary pursuasion,
For those of you using variable pitch (C/S) props, an operating question
that has been bugging me. Perhaps the collective wisdom of this group can
set my mind at rest.
In piston aircraft engines, the concept of running over squared MP vs RPM
has been heavily questioned to the extent that some suggest running at full
throttle all the time and controlling the power output via RPM (within
reason). The thought is to, I believe, eliminate the induction restriction
of the butterfly valve increasing the efficiency.
Now we have a rotor spinning, a gear box gearing and a propeller propelling.
Does this concept hold true for the rotaries. What are people doing in terms
of setting power after take off (full throttle max RPM).
My enquiring and rotating mind wants to know.
(Unturbocharged Renesis with RD1-c Box)
Thanks
Rich

<br>
I'm always hungry for 'numbers' like that. Can you refresh my memory on =
which
plane you're flying?<br>
<br>
What's your fuel flow during takeoff?<br>
<br>
And I'm really interested in your fuel flow at your cruise setting of =
6000 rpm
full throttle up at 7500-8000 feet. Do you have an EGT in addition to =
your f/a
gauge? If so, what's the egt spread between peak and leaned to your =
cruise
setting of 16-1 f/a ratio (how many degrees lean of peak)?<br>
<br>
Having a controllable prop certainly makes it easier to get a full set =
of
performance numbers, doesn't it?<br>
<br>
Many thanks,<br>
<br>
