homebuilt turbine
 
I am starting this project.I found 2 great deals on net.
1. JM09(complete kit for 586 pounds)
2.Building a larger UT160 turbine from jetmax
Whch one?

jetmax stuff is awesome

How much thrust will 70mm turbine and compressor(UT160ZA) produce?I have read somewhere around 14-18kg.

EDIT:You don't have to answer to previous question,I found an answer.
But there is another question.Where can I buy fuel sticks(12 of them)on wheel and combustion chamber for UT160ZA?

Having built a turbine, the sense of satisfaction and pride when it runs is huge. Enjoy!

I've nearly finished my UT-160-za engines. I will post my specs when there complete. If you are in need of parts for this engine the Designer sells them on his web page.

I built the UT-160

16,2 kg - 120.000 rpm

i fit the engine in my f-84g

The UT160 is probably easier to build and performs great.

I will build 70mm turbine.That means 14-18kg?
Now,where can I fing fuel sticks with ring(I prefer 12 instead of 6)?

RE: homebuilt turbine
 
12 stick is better....

Can you guys please post costs. I noticed no one posts costs. One of the main reasons for me to build one on my own.

The 70mm turbine will produce approximately 14 to 18kg thrust. The UT-160 has 12 Vaporizer tubes. These can be purchased from the designer of the UT-160 or material can be purchased from Wren (inconal tube dia 6mm).

I have more photos of the tubes but I'm at work at the moment I'll post when I get home.

Cheers,
Paul

RE: homebuilt turbine
 
Its difficult to estimate the cost. It depends on how much of it you build yourself. If you want to speed up the building process you can buy pre-machined components. Also the type of ECU you use can make a big difference in cost (Manuel start, auto start, kero start).

At a rough guess it think mine cost about half of a commercial engine:D

RE: homebuilt turbine
 
FYI
The AMA has developed regulations that AMA members should follow when operating a kit built or home made turbine engine.
These regs were only put in place to cover safety concerns that could arise in home made and kit built turbine engine construction and operations.

In order to satisfy these requirements, and operate this engine at an AMA affiliated club field, or at an AMA event, and to make sure that your AMA insurance and turbine waiver are valid, (if you have one) the engine must be qualified per AMA PDF Documents 510A, 510C and possibly 510B. These documents are available at www.modelaircraft.org.

Thanks,

Nice very nice [sm=thumbup.gif] Its hard to believe that small tail tuned to produce that much power

AdriFlyBoy 05-12-2010 02:44 PM

RE: homebuilt turbine
 
Here are the parts: http://www.ut160.de.tl/Shop.htm
I counted that it will cost me about 500 euros.

chrigui 05-13-2010 01:39 AM

RE: homebuilt turbine
 
i think that the cost is over 1000 euro + euro for ecu pump and accessories

RE: homebuilt turbine
 
Actually I counted 1862 euros and that was without the case and tailcone and Festo fittings etc . This is quite an expensive route to a turbine especially if you do not have all the equipment and skills to make the remaining parts. As advised by several people the best option is to buy a low hours second hand turbine such as a JetCat or a new engine such as the JetCat P80se or Kingtech 80 if you can afford it.

Hi,
which is difference between UT160 and UT160-ZA?
Thanks in advance
Best regards

chrigui 05-14-2010 02:09 PM

RE: homebuilt turbine
 
diffusor, combustion chamber, 12 stick instead original 9

Curious to know why an X wren person recomends to buy a jetcat?

Well,I didn't counted combustion chamber,ecu and fuel pump.Without them,it is around 500-600 euros.But with them,it is around 1000.
BTW,I recommend 70mm turbine wheel because it can give you 14-18kg of thrust instead of 66mm which produce 8-12kg of thrust.

AdriFlyBoy 05-27-2010 03:05 PM

RE: homebuilt turbine
 


Now I counted all correctly.It is 1171 euros(with projet Hornet III ECU and GSU set included).
Now,what do you think,how many time I have to spend to get it working?

PS:I will use it in 1:8 Tamjet F16.Maybe a little bit over powered,but it will be ballistic!</p>

Depends of how fast and good you are making the parts you don't purchase. If you purchase all the parts needed the total cost is close to 2000EUR, you can buy a ready to run, brand name engine for this price.

RE: homebuilt turbine
 
Is this good decision?
Turbine(most of the parts): http://www.google.hr/url?sa=t&amp;source...mkKmlzufQuMSXw
Here is:4 mainly items(compressor,turbine wheel,NGV,shaft)
Combustion chamber is additional 200$ and 12 sticks(do I need 12 or 9 is enough?) are 150$.
That is 710$.Then I need ECU,GSU and fuel pump.That is 350$.
Everything:1060$.
And another question:Will this produce 13kg of thrust(as is said)?
