^ I thought this was pretty cool.
I just thought I'd toss it up here.

Is it wrong that this reminds me of a woman grinding?

Cool but that MT one isnt really a simple animation haha :nut:


That steam train one is neat. I never knew that. I want one for a turbine engine now.... those things still elude me.

Yeah the MT one is fairly complex, still interesting to see how it works. I have a new respect for the simple mechanics of the shifter mechanism now.

The steam train one is quite interesting. Brilliant of how they conceived of the simple utilizing of pressure back in the late 1700's for creating this rotating motion out of that.

that's cool, i thought the sewing machine one was cool. never really thought about how that worked before haha!

I know I've seen an animation of a turbine engine (I work with PWC PT6 parts all day and I've watched them get built) but I can't find it for the life of me. I'll ask someone with Pratt if there is an animation on their intranet they can pull for me.

There's less to see than an animation of a piston motor though. There's no cycles, only a constant flow of air being compressed and burned. Everything just spins. The part that surprised me is that up to 25% of the thrust of a turboprop engine comes from the force of the exhaust leaving the engine. The rest is abviously from the spinning propellor.

Turbofans (jet engines) however, I know nothing about.

There's some great pics over on this site:

I'm so tempted to build a turboshaft generator to top up the RV batteries out in the bush :) Got the LPG anyway, and a turboshaft would be so much more efficient than one of those little 2stroke generators...

No, actually I had very similar thoughts.

For Cos, I would like to get a handle on diesel gas turbine engines as well..

That would be cool as hell. My dream is to one day be able to afford one of the engines we build so I can cram it into a car. It has been done in a racecar (F1 I think) and also in an old Vette that was used @ PWC plant 1 in Quebec.

This PDF file (http://www.pwc.ca/files/en/Know_your_PT6A.pdf) goes over the principles of operation of the PT6 turboprop starting on page 13. No animations, but some decent diagrams and explanations.

all gas turbine engines work on the same internal theory pretty much (turbofan, turbojet, turbo prop, turboshaft etc), it is really in the end how they get the power to the blades/propeller via shaft or gearbox or just via simple thrust.

basically coming from an avionics point of view in school, its SSBB, suck squish bang blow. althought when the automotive turbo charging literature uses these 4 words to describe turbo operation i fail to see where the bang portion fits in on a car turbo.

Sorry, I meant a jet engine. Not a turbo prop etc.

turbine really doesn't make sense in a car... Unless you're talking about an electric car w/ turbine's to provide the power / recharge... They want to run wide open at constant rpms - doesn't work so good as a direct drive... Otherwise those 50s/60s experiments would have gone somewhere...

I think cat or komatsu was playing with them recently to power heavy equipment - to meet the new diesel emissions... Again, not direct drive, just powering the electrics/hydraulic pumps - not directly driving the transmissions...

Damn you, smashing my dreams with your logic. I'm not an engineer I just see shipping containers that say 1800 SHP and I drool :burnout:

Although, if the turbines want to stay at a high/constant RPM, could you not bolt it up to some sort of CVT to keep the engine speed steady but still vary the vehicles speed?

A turbine engine is a turbine engine. Doesn't matter what it is turning. I work on turbine aircraft all day so it seems so simple to me but I guess if you have never seen them up close it would be weird.

Try this site. A turbine engine in theory is one of the simplest internal combustion engines ever made.

Skip to 1:50, the #t=1m50s doesn't seem to work when embedding.
