Okay, people, time to step on some toes. Notice that the front turbine fan doesn't turn? Or that the back of it is open? What we have here is a glorified kerosene shop heater. Anybody can blow some air, spray fuel into it, and light the stuff off. Doesn't make it a turbine engine. And don't make me get into the difference between a tubojet and a turbofan engine. Anyways, back to the drawing board, lads!
@ArcturanMegadonkey Okay, here's the gist. The video shows a hacked engine, probably a helicopter or turboprop, but my money is on a helicopter engine. The entire center section, from second stage compressor to the combustion chamber has been removed and replaced with twin homemade blower/combusters. Their exhaust is being ducted into the power section at the rear, turning the N1/N2 fans, which in turn rotates the shaft you see in the center. But it's not a turbofan.
@TheIceman1302 A turbofan generates part of its thrust by moving some air around, not through, the center section. A ducted prop, if you will. Much more efficient at low speed and altitude. The front blades of a turbofan always turn, and the stators are located further back, in the compressor core. Without a clearer view of the center section, we can't tell if those twin burners are driven by the center shaft or electric motors. Send me a link if there's other videos of this.
The front blades in this case are inlet guide vanes. More oftenly used in low by-pass ratio turbofans and turbojets though. The turbofan is Heward Altair 400, core engines are Heward H80's. Seems the project was cancelled and the available info found on the net is limited, but it's there.
@TheIceman1302 when the video starts you are looking at the rear of the engine, you'll see the compressor section is open to bypass the twin 65lb thrust engines, strictly speaking it's not quite a turbofan more a hybrid turbofan/bypass fan engine.

@TheIceman1302 That part at the front is just a stator that directs air onto the first compressor section.
a lot of turbofan engines have them, or don't you know much about them?
back to school I think.

Impressive, but where did you get the micro turbine you are using for the fan?

Thats awfully, awfully big for a model.

@tthhnnee I think it was a one off, I'm not sure he'll be building another but you can PM if you wish to contact him

is the build phase over? Is some model flying with it? Looks nice.
