Hi all, I wasn't sure whether to put this into Tech Log or not, but considering that while it concerns airflow, it's not necessarily a part from an aircraft, I thought here might be just as well.
My project is the reverse engineering of something called a Potterton Blower. Basically what you have is a shaded-pole induction motor turning a centrifugal fan within a galvanised snail-shell shaped casing. I'm as far as the manufacture of the peices, but when it comes to the fan itself, I've drawn a blank. What ideas have ye, before I take up the time of the Sifan people with an e-mail? How are centrefugal fans made?
Oh, and I'm getting a student credit card soon, so I'll soon get me a "personal title". I'm thinking of "PPRuNe Trainee Engineer" or "PPRuNe Technician". What do ye think?
