Will this centrifugal fan design work?
I am working on a VTOL RC craft that I hope will work. I was planning on using a centrifugal fan to accelerate air radially (instead of a squirrel-cage design), and putting 45 degree truncated cones around it to direct it downwards. I wrote a program with many small particles accelerating outward from a 'fan', and they bounced as predicted off the shrouds. I was just wondering if you think this would work in real life.
I was thinking if the fan blades were at a pretty large distance and tall, it could move quite a bit of air. With a larger diameter, it wouldn't need to spin as quickly as a smaller unit.
I was going to build this using a chainsaw engine to move two centrifugal fans (only one is shown in the drawings), and make truncated cones from plastic. I was wondering if anybody had any advice or input for this. I was also wondering if anyone knew any useful formulas to aid in the design process.

Sure. You just reinvented this (see the bottom of the page).

Thank you for your reply. I read the link provided, very interesting stuff. So basically this is the initial part of a jet engine, minus the combustion chamber and turbine? I wonder if it would work well still to fly with just the 'compressor'.
