No front brake James, a rear disc connected to a front brake reservoir for my right hand.
Nothing much to look at:
Woody has finished the CFD runs and sent me the final model with the changes that we made to get it to run true.
Have sent P J Bowers (the who are CNCing the body plug for me) some fun vouchers, it should be ready in a couple of weeks.
The body is in four quarters so it fits in his machine and so I can transport it without damaging it.
Also getting another plug of the canopy area 5mm undersize so I can glass it and supply it to the guy who is going to do the PETG canopy for me.
The CFD work was all about trying to get something that had decent yaw stability, the first straight run hinted that the design had a bit of potential in a straight line, the first couple of yaw runs confirmed that it didnt like a crosswind.
We tried a few different things and came up with something that should be reasonably stable.
Ended up with a short tail on the bottom 1/2 of my bike to help provide yaw stability with less roll input.
The tail is about 1/2 the length that we initially tried when checking out options.
Did 11 CFD runs including the initial straight run, then Woody added the wheel fairings trying to mirror my rough sketches and much more detailed mind view and cryptic emails.
We then did six CFD runs at 6 degrees yaw with the bike teaching us (well me anyway) a few things on the way.
Once we were happy at 6 degrees yaw we then did a 2 degree and straight run to close the loop.
I'm no Aerodynamic expert but like everything if you change one thing at a time and retest the answer is in the data, in this case there is the numerical data and the surface and cut pressure and velocity maps as visual data.
I've never set foot in a wind tunnel but I don't think I could have achieved what we did without Woody's help and tools.
Thanks Woody for your help and patience, I've enjoyed the interaction and am very happy with the outcome.
