what exactly is the elliptical distribution in relation with the lift distribution along the span of a wing. i googled it but all it comes is something related to the calculus n all mathematics(lets face it, i just got rid of maths n i m happy now). does it mean that the lift produced is max at the centre n reduces to 0 as we reach the wingtip(coz thatway wingtip vortices ll be small)??? is that why the airfoil geometry approaches symmetry about the chord line as it approaches the wingtip??
