Thanks a lot for you input!

Point taken. I will not post any more questions. Thanks all for the feedback, I really appreciate it.

I'm only trying to find where the threshold is, I don't have any favorite here. I will not ask anything anymore, my intention was not to create irritation.

Yes, something like that. They say that diesel is about 20-30% less than gasoline, so let's assume that this hypothetical turbine engine burns 10-20% less than a gasoline piston, even at low...

Ok this will be my last question:

Hypothetically if that TP-100 had lower fuel burn than a piston, let's say close to what a diesel engine burns (I know that it's not possible, but let's just...

Do you mean that you would go for another turboprop engine or do you mean you would spend your money on a completely different non-turbine engine?

I agree with that, should have used different wording. I guess I said "a little" because that delta ($25k) is small compared to the delta between $100k and the price for a new P&W, GE, or RR engine.

I looked up a little on this Czech engine, TP-100, that Diemech Turbine Solutions will offer. It will be about $100k.. or probably a little more, like $125k. Does this price make this engine...

Oh ok, I see. Thanks.

What is the cost of that engine? I assumed that it will be lower cost than what's out there. If that is not the case, then just disregard the question.

That is an interesting engine. Will this be THE engine that make everyone change to turboprop? If not, why?

So a lot of the pilots won't change because piston engines is sort of an identity to general aviation? Do you think that can change?

I'm a student, university level, and a student-pilot. I'm writing an assignment on disruptive technology for one of our classes. I chose to writing about turbine engines, and while I was writing I...

Nope



Probably not, but if there are 200,000+ people that voice their opinion I would think it could make an impact...



What about regular auto gasoline? Can't lycoming and continental...

Will 100LL go away as long as there are no direct substitutes? That would mean hundreds of thousands of airplanes won't be able to fly. Even though EPA are trying to scare the aviation community, do...

What are you guys' opinion on the new Diesels that are out now? Is that something I should consider instead? They seem expensive (compared to gasoline pistons), and I'm not sure if the fuel savings...

That's too bad. At what price do you think a turboprop would be interesting for the majority of general aviation?

I see I was a little too quick with my response :) but thanks anyway.

Next question: Are there any new turboprops for less that $75k out there, or is that just wishful thinking?

OK, I see. Are they considered more reliable than piston engines? And if so does that translate to a safer airplane using a turboprop instead of a piston?

[QUOTE=uavmx;14355]I'm shocked in this day and age we don't have a nice IO550 alternative turboprop. Something in the 300-400HP rating that get's comparable fuel burn (probably higher). I think it...

Do you know how much higher fuel consumption a turboprop have compared to a piston engine?

Hi all

I'm doing some research on turboprop engines for general aviation, and I wonder what people here see as the advantages and disadvantages of a turboprop engine? Or just opinions in general.....
