Luc's Industrial Gas Turbines

Hi all ... I'm starting a new project with two brand new Garrett GT2560R turbos coming my way as we speak ... :D The goal with this project is to build a "Low Cost - Free Turbine" gas turbine concept, a bit like a PT6, but much smaller and much cheaper and see how much HP and/or torque can I get out...

Re: Jet Snowmobile Project/Team

Hi John,

Yeapppp ... Thousand of concepts and theory out there. The problem? Finding the right one ... :lol:

But I'm convince my CFD software will be of good help in this matter :wink:

And thanks for the document by the way ... Very nice :wink:

Re: Jet Snowmobile Project/Team

Hi John, Nope I'm not a flaterer ... Just giving to Cesar what belongs to Cesar that's all. As for the elbow, we droped it (abandonned) and are now carrying CFD of a "Straight" 2 stage ejector, changing sizes and length, and STRANGELY, it seems my narrow gap first stage and larger gap second stage a...

Re: Jet Snowmobile Project/Team

Hi John,

Yeaaaa ... Maybe a bit more thrust would have been good, but again, temperature would also go up and that's a No No ... ;-)

Re: Jet Snowmobile Project/Team

Hi John, OMG ... My P2 maybe runs around 2 psig. @ 40,000 rpm idle condition. In fact, the compressor pressure port is equiped with two pressure switches, one that kills the starter @ 1.5 psig. and one that provide overspeed protection, thus, killing the turbine if P2 exceeds 40 psig. which is aroun...

Re: Jet Snowmobile Project/Team

Lollll .... Indeed .... Cool running turbine isn't making power, especialy when it's built to delivery heat and velocity for industrial applications that don't want to see 800°C ... Lollll But thrust me that the day I'll be looking for pure thrust, which is not the case for the GT4708, I'll be crank...

Welll ..... You should know me by now, always trying to break limits and achieve what peoples say it's achievable ... Lollllllll NIce Jetspecs by the way, and maybe one day you guys could make it so it can diffirenciate between few fuel types such as propane, kerosene (Diesel) or gas. So this said, ...

Re: Jet Snowmobile Project/Team

By the way ... I was FED UP using a BIG FAT & Bulky 110 VAC leaf blower to start my turbines, so I came up with this 12 VDC rugged starter unit ... ;-)

This Beauty os acutally cranking and starting a DIY turbine built using a Garrett GT4708R ... He he he ... ;-)

Re: Jet Snowmobile Project/Team

Hi John, Lollll ... You obviously did not understand my question or did I formulated it wrong ... Lollll My question was more toward providing the audience with your "Rules of Thumbs" since I know they work great, and not for my big jet project, but more for someone wanting to build a single DIY tur...
