c) Uniformity of rotor thrust along blade span
- blade twist - taper - coning angle - centrifugal force - limits of rotor RPM - centrifugal turning moments
d) Helicopter Controls
- collective lever - collective pitch changes - relationship with rotor thrust and rotor drag
- cyclic stick - cyclic pitch changes - rotor disc attitude - rotor thrust tilt
- yaw pedals - fuselage torque - tail rotor drift - tail rotor roll - fenestron tail - tandem rotors - co-axial rotors - notar
e) Rotor blade freedom of movement
- feathering - the feathering hinge - pitch angle
- flapping

-the flapping hinge
-alleviation of bending stresses
-flapping to equally
-dragging
-the drag hinge
-drag dampers
-leading/ lagging
-periodic drag changes
-blade c.g. (conservation of angular momentum)
-hookes joint effect
f) Phase lag and advance angle
-the control orbit
-pitch operating arm movement
-
rate of pitch change

-
