comment Concerning the curvature of an airfoil (shape)
The force is because the blade is spinning. A wing is travelling in a straight line, but a rotating blade has all the mass of the blade trying to fly outwards!

@user22834 - The explanation for these observations is that your second paragraph is incorrect.

comment Is a purely vertical or almost vertical orbital launch possible?

Have a look at physics.stackexchange.com/questions/26739/… for some useful information.

See the space elevator if you want a possible (nearly) solution to get to geostationary orbit (or twice that far-using matching earth to hub and hub to outer orbit cables)
