G'day blokes
This is not a cut and paste
My ambition is a tall order ,to exceed 300mph on a sit on bike and over the last 5 years I have been looking at ways to succeed in this venture , I have come to the conclusion that aerodynamics is the key to achieving this goal and to this end my efforts are directed .
Due to the very restrictive partial streamlining rules for bikes ,I have taken two courses
1. endevour to have these rules changed ( for another topic at a later date )
2. Ways to minimise drag through what ever means are available that comply with the current rules .
I am experimenting with vortex generators ,turbulator tape and boat tails ,is there anyone else experimenting with these methods ,or has in the past ? I would be very interested in your results
I have found the following resources to study and hopefully expand on.
aerodynamic drag reduction of a racing motorcycle through vortex generation a thesis by Gerald M Angle II if you wish to study it go here
http://www.library.njit.edu/staff-folders/singh/met304/resources.htmand follow the instructions ( is a large document ) and another resource is

My results to date are almost nill
because of problems in getting my bikes to run reasonaby well and only one week a year to gather data , I ran the busa last March with vortex generators of my own design twin contra rotating vortex's ,along with ziz zag tape ,but was not able to gather ant data .next year I will be running a bike I have designed and built myself its mainly an experimental hack to test aerodynamic ideas ,so time will tell if my ideas and such wil work ? I would love to be able to test using a wind tunnel but due to the extreem cost at least for me 1 grand an hour this is just a wish , the other option is CFD programmes ,but again the cost is way out of my means ,but I have found an inexpensive programme which at least has been an education for myself
