That looks promising as it might shorten the wheelbase by 200mm albeit at the expense of a few capacitors. It also means that all packs can now use the 'optimum' busbar in most positions so although we lose a bit of energy capacity I hope we'll lose less of it through the pack. Ryan is doing a more detailed study (see further down)
Rear Wheel: production is now underway. I met Stu from Warpspeed Racing at Santa Pod recently to go over a few area of the design. The image (below) shows the style of wheel that he's building. The material is ordered and he's also making the headstock, plus he's got a few other goodies that I think we'll be ordering in the coming months.
Motors: I've done a lot of work with the motor data that Morgan has produced. Basically, he's provided a spreadsheet with hundreds of calculations showing the motor speed, torque, power, current draw (Amps) and efficiency across a whole range of controller frequencies.
By matching up the rear-wheel rpm with the theoretical torque and power we need at every 1/3 second interval, from the start line to the timing gantry 1/4-mile away, I have built up the optimum controller settings at every point during the run.
Morgan is now fine tuning the motor design to improve efficiency and we'll go through the exercise again until we end up with a control algorithm from launch to finish. This part is really exciting.
