Hi Zhe,
I am very glad to read you more and more on the Robiplan's sujet,
FUHANDAIGOU a écrit :1, How does wind wheel's area is calculate, particularly ROBIPLAN.
I have no precise answer about that.
for a Robiplan, the swept area is about the surface of only one blade because the other isn't working with the wind.
But if 2 Robiplan wind turbines are coupled (
please see here BIROBI movies of Pascal and animations that I have computed to better understand), one can say that the swept area is equivalent of
two blades
Relatively to the rules of the race, the Robiplan Wind turbine is so unusual that I have no idea how to count the swept area. I think Pascal has to ask it to the manager of the race.
2,The wind direction and the vehicle movement's direction has what kind of relations? Running free, against the wind, crosswind?
The wind has any direction and the kart too. So it is necessary to sail against the wind sometimes, with full lateral wind or with a full pushing wind other times.
One has to pay a lot attention about the lateral wind because it can crash the kart by turning it upside-down
3, They allow BIROBI to participate? The wind wheel area is the two wind wheel's sum of area?
I speak about that in the first question.
1.ROBIPLAN is good than BIROBI, because ROBIPLAN simplicity, reliable.
Of course the simple Robiplan is easier to build, but it is less powerful, whereas the BIROBI.
2.Hard borders, with a soft cloth manufacturing PLAN, effects can be good .
Pascal is thinking a lot for the best shapes to do on the blades... That is a very opened question (material, contours and convex/concave sculpture)
Your English is nice, much better that my Chinese
Best regards
