Hi Dave,
for airfoil data, i plan to plot myself some values, coming from an array, like you did on the vR7 data on your site (yes i read it sometimes
).
I dont need an universal alrorithm, only some airfoils like VR7b, VR9, VR5, OA213(similar to VR12),B29-root , so, i think i will "hard" code the data, based on Bezier splines, i will "build" the curve my self trying to be as close as the original, doing so, i can have an interpolated (quite precise) data.
do you think i can interpolate between the CL of 2 given airfoils at the same AoA ? for example from 0.50 to 0.58, giving 0.54 ?
What i want tyo do is calculate the lift not in hover, but with a disk pitch and a relative wind (speed).
then , if i get it working, i will compute the vectors for each "slice" of the blade and will have an approx of the autorotation capabilities.
I can easily have a 3D interface, could be interesting.
then why not the calculation of the moments, centrifugal loads, and maybe compute the coning and the sissors load at the root.
and why not imput a kind of hinge elasticity , and why not a pitch imput... and why not...
i can get busy thill the summer
what do you think ?
I will never be 100% acurate (no method is), so i will deal with some approx.
BTW do you know if Prouty's book has been released in french?
thanks
