EC135 Engine Air Intake Question
Hi Guys,
Question: what is the path of the EC135 engine combustion air from the airframe intakes in front of the xmisson cowling to the engine inlet?
Simply could not figure out myself. Really annoying! I have studied dozens of pictures, drawings in the RFM and training manual with zero success.
As you can see in picture (see attachments) there is a titanium firewall between the engine and xmission compartment with only a couple of cutouts for the drive shafts and gen cooling air but nothing for intake air.
Con you help me to solve this mystery? Before drawing some quick conclusions on my technical skill, please consider that I do not have a hand-on experience with the 135. Just curious!
(In the picture there is an inlet barrier filter installed but it has no relevance to my question.)
Appreciate your help,
Tamas
