I think I understand it except for where the air is coming into the center of the impeller. Is it through the thick mounting plate that has the PSRU bolted to it? Don Walker N113BR Yes. You can see the open lobes around the PSRU and how they relate to the cowling in the first two pictures. The 3rd picture has the openings highlighted. The 4th is a picture of how my Harley-Davidson generator is mounted and the space available for the impeller. The impeller will be both a blower and a mount for the generator. The whole space between the PSRU mounting plate and the engine is now enclosed in a shroud (I really need to take a picture of that). The shroud is not as tight and technically correct as I would have liked, but it's good enough for a proof of concept. If I get good results from it, it will be something to work on for improvements after I'm flying. The last picture is of the backside of the PSRU so that you can see how the intake lobes are formed. The lip just inside of the bolt hole ring is a push fit into the hole in the center of the mount plate. http://ernest.isa-geek.org/Delta/Pictures/EngineCowling2.jpg http://ernest.isa-geek.org/Delta/Pictures/EngineCowling1.jpg http://ernest.isa-geek.org/Delta/Pictures/EngineGeneratorAirIntakeAndCooling.jpg http://ernest.isa-geek.org/Delta/Pictures/EngineGeneratorMounted2.jpg http://ernest.isa-geek.org/Delta/Pictures/EngineGeneratorMount6.jpg
