Can we delay answering this question? May be if you proceed with propeller theories a little
bit this question will come out, this answer will come out itself. But I have given a hint; it is
mainly the wake distribution for which we have designing this thing. And another point
which you must understand is that the propeller blade is like a cantilever, connected at the
root, but free at the top, so it has requirements of strength also; plus the root sections are very
much affected by the boss, so you do not get more lift generated by the root sections, most of
the lift comes on the top sections. So, we, our, the later half of the propeller blade that is,
blade towards the tip is more important for us, but on the other hand thee root is very
important so that propeller blade doest break off.
