Please explain the concept behind the "Indian Tail" rotor...i haven't heard of this before.
a thin, swept tip like a supersonic wing.
Not knowing much about the rotors, is this the bit where it takes form similar to a concorde wing, infact nearly exactly the same form?
I was being explained too about the blades on the Lynx HMA8 by an 815NAS pilot, he went through the various features including the kink in the blade half way down, the tips (i assume are BERPs?) and the supersonic wing like shape right on the tip of each blade.
