Restriction isn't measured in flow rate; restriction produces a pressure
drop at a given flow rate.
At 1 gpm, the pressure drop through a 5/16" hole is the same as the head
pressure of 4" (0.104psi). Thus if you have an empty tank teed into a fuel
line and the tee is 4" below the liquid level in the tank, it'll start
sucking air from the empty tank. At 4 gph (more reasonable), it'd take a
.082 hole to get that pressure drop. Now I hope you don't have a .082 fuel
passage, but all the restriction is cumulative, so if you have a long hose,
a filter, some elbows and valves... I'll keep the aux tank feeding into the
top of my main tank, thanks.

I have been working on a Generac conversion for my Ultrastar for
several months now. I had to rebuild the cage and am working on a motor
mount to use a direct drive version that hand props to start. There is
one currently flying in a thunder gull in Illinois with 30+ hours now.
The engine will weigh the same as the Cuyuna that was removed with 5
more Hp. I would have more progress,but I am taking care of a sick
parent(who wants to see my lawnmower engine plane fly). Mark in Florida.

My tanks feed fuel from the top. The air breather is also teed to both

Is yours a Gravity feed?>>
Hi,
No. Tanks are a couple of feet below the engine. Pick up is from the
top of the tanks and the balancing air inlets are grommet push fit into
the handles. Fuel is drawn equally from both tanks. If I add a third
tank, feeding fuel into the same pick up line and adding a tee to the
same air line there would be no more chance of sucking air than already
exists. They will all empty together (roughly). I assume that I should
have to install the tank at the same level as the existing ones?
If I can do this it saves all the problems of transfer of fuel.
Cheers
Pat

| Subject: | Re: Just another idea...Vtwin firestar? |
Rick, Yes you are right, induced vibration from a propeller will make any engine
seem to vibrate more than with the prop off...BUT...what I am talking about
here is engine vibration, generally measured in the X, Y, and Z axis on the engine
only. These are much higher frequency vibes and can be very detrimental to
an airframe. You simply cannot determine the vibration level of the engine with
a prop...or anything attached to the pto. This has been a concern of anyone
using a industrial V-twin with a redrive on it...the engine vibration.
The progress of the development of any package like this must be first examined
with nothing on the PTO/crank....then as you move on to attaching props and things,
you discover which propmakers really know how to balance a prop...or a
pulley or a shaft or a whatever the driveline consists of, and then address that
separately. Then you deal with the "driveline induced vibrations"
I know Buckeye has a whole pile of props from different manufacturers, they have
been testing, including 2, 3 and 4 blade designs, and he did express some remorse
with a particular mfgs props, saying that the differences in 6 in a row
of theirs were more than the differences in all the mfgs put together! Since this
tidbit is second hand information, I wont be naming names.
I also know there are some really hard to track vibes that come from a prop/redrive/piston
engine combination, as anyone who has fooled around with different
combinations has experienced. This has to do with piston power pulses/ number
of blades/ moments of inertia and prop length and reduction ratios. Some call
it torsion resonance and I have heard it described a number of ways. Basically
alot of fellas just lump all these things together, and call it engine vibration,
but when you are trying to reduce these inertias, you must address them
all separately.
To speak to you wish about wishing to see it with a prop on it...I have seen it
in a with only a couple of different props...some of them were smooth as silk...and
some of them were just terrible! I didnt get to see the 4 blade powerfin
run on it, but their description was "so shockingly smooth we couldnt believe
it."
BTW, for you guys thinking about the technicals of this...the redrive ratio is
2.25 to 1 and they are swinging a 2 blade 74 inch prop, among others..

Nope, but got to visit with him last month at S&F.
John W and I are still in Ontario, OR. The wind is still howling at 30 to 40+
mph. Looks like it will until tomorrow morning. We are in a comfortable FBO,
sleeping in our tents at night. Temps into the very low 40's. The Kolbra and
mkIII are chained down on the flight line. We have had a courtesy car since
we arrived, food is good, and the FBO is very friendly. Got some old characters
around here refurbishing war birds and others to keep us entertained.
Roger H, Grants Pass, OR, trailered his Kolb to Larry C's yesterday. The winds
at Larry's, a hundred miles south, are the same ast they are here.
John W and I had an exciting day flying the back country airstrips from Mackay,
ID, day before yesterday. Was easy to pump adrenalin on that flight. ;-)

I'm back... been in Louisville for several weeks with my Mother, who was
hospitalized with pneumonia...she's out now and doing better, thanks.
While there visited my old airport hangout where I worked as a line boy in
the mid 50's... Bowman Field... the oldest continuously operated airport in
the United States. They have a great photo museum set up in the lobby of
the old original terminal building...tons of stuff relating to WWII glider
training, aeromedical evac training, etc... Shots taken at Bowman of Lindy
and the Spirit, of DC-2's, Fokkers, tri-motor Stinson A's, Curtiss Condors,
Lockheed Vegas, 10's, 14's and 18's...Seversky P-37's, Bell P-39's...etc.
It turns out that Sidney Park, WW I pursuit pilot and later president of
Park Aerial Surveys, the outfit I flew for in the mid 60's, was one of the
early pioneers and founders of the Bowman airfield. Pictures of him and his
planes are all over the place there. If any of you Kolbers get to
Louisville, I believe you would really enjoy seeing some of the neat early
aviation lore in this display. Unfortunately, I have never seen a Kolb on
that airport.... may fix that problem one day.
It's good to be home... now I gotta finish the annual on the FireFly...

Same weight as the Cuyuna? I though the Generac conversion was around 120
lbs, isn't it? The Cuyuna is 69 without the redrive. If it's really that
light it could be a great engine for that class of aircraft.
Any pictures?

Hi Mark,
Interesting project. Question - did your Cuyuna have any type of
reduction drive - belt, gear box, etc.
Problem is to get the HP your have to turn RPM - turning a prop that
fast normally reduces its efficiency. Like to hear more, good or bad
as you progress. I hope this works for you. I used to have a
FireFly, now I presently have a Hawk flying and Gull under slooow
construction. Looking for more fuel efficient engine.
