Swash Plate Assembly : The swash plate assembly consists of two primary elements through
which the rotor mast passes. One element is a disc, linked to the cyclic pitch control. This disc is capable of tilting in any direction but does not rotate as the
rotor rotates. This non-rotating disc, often refered to as the Stationary Star is attached by a bearing surface to a second disc, often
refered to as the Rotating Star which turns with rotor and linked to the rotor blade pitch horns.
The Collective Control : When pilot raises the collective control or pull collective control
up , the collective control will raises the entire swash plate assembly as a unit . This has effect to the blades by changing the pitch of
all blades simultaneously .This causes to increase angle of attack and give more lift.
The Cyclic Control : The cyclic control will push one side of the swashplate assembly
up or down. This has the effect to the rotor head system because the cyclic control or cyclic stick controls the angle of the main rotor by
angling the rotor head to which all the blades are attached .This cause the helicopter to move left or right, forward or backward.
Anti torque Pedals
The Thrust produced by the auxiliary (tail) rotor is governed by the position of anti torque pedals.
These are not rudder pedals, although they are in the same place as rudder pedals on an airplane. They are linked to a pitch change
mechanism in the tail rotor gear box to permit the pilot to increase the pitch of the tail rotor blades. The primary purpose of the tail
rotor and its controls is to counteract the torque effect of the main rotor.
