If I were to build my own Lemond Revolution style turbo trainer (link below) could I use the air speed in meters/second^2 the rider is moving into as a good indicator of what type and size of fan to use?
Or put the other way around could I use the indicated airflow that is moving through the fan at a range of revolutions per minute to provide similar resistance to what is found outside, resistance increasing with the cube of speed?
Would this information be enough to begin building, experimenting and testing fans for a diy turbo trainer?
If the fan has an aero map which states its lb/min in airflow at a given rpm (which is within normal cadence of a geared bicycle) is this a good indicator of potential resistance that is will provide (once converted from statute to metric)?
