Third "turbine" on top of large Mil helis?
Hi, many of the large Mil helis have what looks like a third turbine
above, and slightly behind the two main turbines. What is it? All of the specs for these helis say they have two turbines. I can see blades in some photos, so it's obviously something like a turbine. Thanks, Justin. http://soupisgoodfood.net/ |

That is an auxiliary power unit (APU) for pneumatic main turbine starting.
Required for self-contained operations. At least some models of Mil are equipped with Ivchenko AI-9V APU unit. Use e.g. Vivisimo meta-search engine www.vivisimo.com and type "Mil Mi APU" and you get more information about the subject. JP kirjoitti glegroups.com...

Oil cooler fan mentioned earlier is not a bad idea after all! Some larger
Mil helos may have a main transmission cooling system located just there. JP "JP" kirjoitti ... That is an auxiliary power unit (APU) for pneumatic main turbine starting.

Justin, Look at first picture. Left rear of cowling shows small exhaust
for APU (I'd guess about 5 in. compared to larger main engines). Ed R. wrote: Thanks for that. Mystery solved |

Slatts Yes I agree, it seems to be the case. The APU is behind the main transmission. The "third turbine" has to be an oil cooler fan. JP |
