I have gained access to a technical schools wind tunnel and have only begune to test some very basic stuff. I have been quit surprised by the willingness of some schools to allow me to use there facilities without charge, because I am not a business, as I do not have a university degree. I am a Heavey Duty Mechanic. What I do have is interest in the subject and that seems to be enough. The max air speed for the tunnel is 90 ft/sec, 28m/s the test area is aprox 0.6m x 0.6m at some point I will post pics with some data. The design and building of models is time consumming and keeps generating new questions and ideas. so far all I have done is to conferm what I have learned from reading. one test that I did, showed that a block of styrofoam with rounded front end corners with twice the frontal area as a 12:1 scale model Yamaha WR450 had 35% less drag! What I will be testing at some point is the affect of sadle bags/boxes and tank bags on a standard motocycle configuration...
