turbina a gas-gas turbine Galiazzo Alberto - Martini Alessio

[marcy1987]

lavoro davvero molto interesante!!! abitate anche vicino a me ;) (io sono in prov di Treviso)

[boniek983]

bella prova

[fabioven]

complimenti x la realizzazione,

a presto spero di riuscire a terminare il mio.

saluti

[marco19931821]

non è ke mi potresti dire tutti i materiali che hai usato per farla funzionare?

[gale77]

Ti aspetto ;-)

[Halash1989]

Awesome job. Keep of the good work and u'll have steady combustion in no time!

[gale77]

Thank you. We got some problems with oil line of our new TG engine since it stops when we start to pupm oil seriously. We added a regulator yesterday night to solve it, this evening we will do a third engine run, if it work good we'll post new video ASAP

[marco19931821]

anke tu di treviso?? bella quella turbina :P ciao

[gale77]

Si anche io, grazie del commento!

[squifo]

kkkkkkkkkkkkkkkkkkkkkkkkkkk!!!­!!!!!!!!!!!!!!

[jagheterbanan]

looks cool! but you have got to do something about that cc flames in the back with no afterburner is not what you want! make the cc a bit longer and try some diffrent hole patterns in the flametube, those flames will make the turbine blades fail, you don't want a TOT of above 8~900C

Cheers

[gale77]

Done, we've ready a second prototype with a brand new Borg Warner turbocharger ready to go after my last University exam (13/07/2007). I'll post a video for our new setup asap with all modding you wrote about

[sicodelico111]

Creo que el utilizar un turbocompresor de un vehículo corriente no asegura que la refrigeración de la turbina sea suficiente. Seguramente el problema está en que no hay una refrigeración adecuada tanto de la turbina como de la cámara de combustión.

[chemical79excuse]

i don't understand the point...what are you going to do with this?

[gale77]

it's a gas turbine project, I study engineering so it has always been my dream to build up my own one and there it is. This video shows a backyard gas-turbine project (a first attempt with some errors). Now I'm doing a second one, similar to the first but safer, good looking and with lots of gauges to get measures for didactical purpose (we calculate this simple GT cycle with EES-Engineering Equation SOlver, then we'll take a look at the gauges to see if they show same results).

[gale77]

Those engines can be used as demo, didactical, engine (for go karts), or to set up a very very small but effective cogenerative system to get heat and electrical power at same time.

[espido]

hey do you have a page, were you explain how you make it?

[gale77]

not for now, however if you pm me your e-mail I'll reply you with a technical pdf I did for my University in attachment.

You can find interesting info on DIY gas turbine group (Yahoo) too

[65ShelbyClone]

Definitely very cool!

[gale77]

Thank you so much

[stingaz001]

nicely bade guys, if u wan tsome more power out of that yurbine try turning the bottle of propane upside down

[stingaz001]

hey guys nice jet there try turning the gas tank upside down and see wot happens ;)

[gale77]

Thanks your comment is much appreciated

[leokimvideo]

nice backyard jet, lovely work..

[renamaf]

Cara... muito massa.. tbm estou montando uma... soh gostaria que vc me desse umas dicas de como faço a ignicao e o principio de funcionamento... teria como?

O que acontece no final? parece que ela explode?

Abraçoss e parabens!!

[gale77]

For startup I use a leaf blower until turbine reaches a sufficient speed. Ending flames are caused by oil realeased by old oil gaskets on turbine. Thanks for your comment

[leokimvideo]

nice work, show me the flame

[Dranod]

Not a bad bit of gear, my brother has been declaring that he wants to build a turbine in various different ways for some time now, It would be nice to get a little bit of information on how you built it.

[gale77]

I'll be glad to do my best to help you, I can send you by e-mail a pdf file with some pictures of combustion chamber construction and some useful programs

[Dranod]

That would be excelent and greatly appreciated.

[gale77]

Hi, if you mean the vertical tube on the right it's a little "oil tank" that help us to keep an open oil circuit avoiding oil expansion problems, also helps us to control oil level, however we'll add a cooler on the oil circuit asap

[xXxmidgexXx]

ok but what i mean is after you have started the engine a inflatable pipe got inflated

[gale77]

yep, you're right. That's because we used a conventional stove tube. The reason why it's that if ignition retard and propane will get the spark some seconds later, stove tube will explode avoiding major damages to other stainless steel parts. Other than that it's less dangerous to work this way.. just think about it as a "fuse" for excessive pressure

[xXxmidgexXx]

um whats the thing ritht on the middel of the turbine the inflated??

[gale77]

if you mean the "inflated" housing it's the compressor housing (inside there's compressor wheel), then air pass through the Al tube you see behind, then enter in combustion chamber (stainless steel cilinder) then enter in turbine housing and expand

[gale77]

Thank you so much, if you really want to get into it and then you'll need some tips and tricks I'll be glad to do my best to help you

[gale77]

excess of fuel, it was first engine run, now we setted it at a lower fuel flow with no flame since flames may damage turbine, now we're setting an after burner to keep flames outside (when needed) without damaging the turbine wheel

[xXxmidgexXx]

Why did it gofire?

[saddogmobile]

what is that your using as a starter?

[gale77]

I'm using a big leaf blower (2.4Kw), it's pretty cheap, then I modded nozzle to perfectly fit compressor intake without losing air mass

[velocityflier16]

awesome engine setup. i have 3 BorgWarner turbos that put out 1100hp and 44psi. if you are interested in one let me know. other than that can you email me what you guys used to build the complete setup? thanks alot!

[gale77]

ok tell me more about prices and specs of your BW big boyz my email is gale77@tiscali.it. Thanks!

[timboy666]

not bad
