I think it is a normal turbine with a windmill fan in front of it.

I still can't believe they are running plastic SLA fans in front of those things!

Seems to me it's just a fan mounted in front of the turbine, but not connected to it. The suction makes it spin. In the last few second you hear the turbine running but the fan is stationary.

Regards, Bart.

oh no they didn't! That is just adding dead load to the compressor? Free spin?

Looks really cool though.

Probably a Hight Temp ECU shutdown, they are starving the inlet out of air.

I think there are a bunch of guys already flying this same type of system, both on Mibo and Skymaster.

Well, a "bunch"...maybe more like 2 or 3. And I have heard of some fans coming apart

Just free wheeling fans, Skymaster have the same set up on their A10, I've run the engines to full power and no problems yet. The ones in the below photo are done on a 3D printer, they work great.

What sort of 3D printer?

FDM
SLA
SLS
JSD
DMS
Or just a powder printer?

Hi Paul,

I am not clear on the process but someone said the material is ABS.

Although we used some new ABS "like" material (at my old job) that was very nice, IMHO this is still an extreme application of RP ABS.

Matt
If it is ABS then I would suspect it is FDM (Fused Deposition Modelling)
Interesting application..[X(]

Paul
