Pulsar with a turbine?

Anybody ever think about putting a SOLAR turbine on the front of a
Pulsar? Ric Stitt tells me his planetary transmission will drive a
prop at 3000 rpm as a constant rpm output from the SOLAR. At about
150 hp and using the prop at constant rpm with varying pitch, that
baby ought to go Vne in level flight.

Anyone out there ever think about this?

How many GPH for fuel flow at 150 hp? The Helicycle I saw last weekend burned 10 GPH, and the engine is derated to 105
hp...

Dan: What do you mean? Does someone have a gas turbine on a
helicycle?

To answer your question, I think that Solar turbine burns about 15
gal/hr. I'm not sure. The BSFC (pounds of fuel burned per hour per
horsepower) Brake Specific Fuel Consumption for the turbine is much
higher than for the internal combustion engine. Hell, the Jet Ranger
I fly burns 20 gal/hr at idle on the ramp and 30 gal/hr at full power.
It's because you have to run that damn compressor at idle just to get
the engine to run.

Kind of a funny engine in a way. Burns 2/3 the fuel it uses at full
power just to idle.

Bill, seventy turbines have been shipped to the customers of Helicycle just
last week. They are modified by BJ just for the Helicycle. It is the
standard engine now.

Is the Helicycle legit or is it another Mini-500. I was looking at the web
site and can't find a think about building methods or cost. At list DF said
how much the Mini cost.

I don't want to endorse it yet, but BJ Schram is the inventor of the
Scorpion and the Exec series helicopters. They have all lacked a lot
when compared to a certified helicopter like the Robinsons, in my
humble opinion and I would not get in any of them and fly higher than
I would want to fall.

But...B.J. Schram is a serious guy who is a real engineer and who does
real things. He's been working on this damn thing for a decade or
more. If any experimental is going to work right and be the safest
out there, my money's on the helicycle.

I have some concerns about the Solar turbine exploding and that there
may not be enough protection around the turbine vanes to protect the
pilot. It also burns a lot of fuel, so you have to carry much more to
make it work right. But, if it has the power and the safety, then
maybe it will work. Also, Solar, themselves will probably do what
they can to help B.J. in making it more reliable and more safe.

It's too early to tell. Helicopters are so complicated that I'm
reluctant to even speculate on this project. I thought the Mini-500
was a great ship the first time I saw it (and didn't know **** about
the mechanics of helicopters or time-life components). That
helicopter proved out to be an abysmal failure, killing many people.
Schram's might do the same thing. It might be easy to fly and fun,
but it might be something that wears out quickly as parts get out of
tolerance in only a few hours. I worry about it since the certified
helicopters require hundreds of millions of dollars to experiment with
and get approved.

In the end, personally speaking...my life is not worth 1 second in an
experimental helicopter. I will never fly in one or test fly one
again, no matter who approves it.

I even worry all the time in the Robinsons. They are just so complex
and so much can go wrong, if you survive a few thousand hours, you've
done real well.

I think, if you screw with any of them long enough (from jet rangers,
to MD-500's and especially experimentals), you'll get bit.

Damn. I didn't know that. The guy above gave me the link to see it.
Great! I love it.

I'll tell you what happened to me here. I sort of knew that BJ Schram
was working with the Solar turbine from talking with Ric Stitt. In
fact maybe Ric even told me that BJ was doing what you said above. I
got confused because TEAM (Tennessee Engineering and Manufacturing)
who built the MINIMAX had an airplane that rang a bell in my head like
that helicycle that BJ is screwing with.

I thought someone had put a turbine on one of those ultralight
airplanes of TEAM's. They had something they called the Aerial cycle
or something like that about 10 years ago, but I can't remember what
the exact name was. So, I was corn-fused a bit about it, thinking it
was on an airplane.

Let me ask you guys who know about this a question. What if the Solar
detonates or starts coming apart. Is there appropriate shielding
around the turbine to protect the pilot?

BWB

The engine and disk are well behind the pilot; I would be more concerned about the tail rotor driveshaft...

BWB,

Yep the helicycle is now turbine powered comes standard.

all the best.

I realize this is a troll but here I go anyway:

The Pulsar I had would hit Vne at WOT on a 65hp, Rotax 582. Why would I
want a turbine?
