  4. Helicopter Principles • Helicopters generate flight by spinning it rotor to revolve its blades 360 degrees against the air. As the rotor spins and the blades revolve, a pressure differential is created across each blade producing lift. • The Swash Plate controls the forward, backward, left and right motions by controlling the angle of the main rotor blades thus decreasing or increasing the differential of lift across each of its blades. • Servo motors control the operation of the swash plate. The servos also regulate the pitch of the blades as they revolve. Changing the pitch during flight allows the helicopter to change directions and maneuver in 360 degree space. • The yaw of a helicopter is the rotation of the helicopter about its vertical axis.

  5. Helicopter Principles Continued • Servo Motors Operating SwashPlate

  6. Unique Design Features of the X.R.B SR Lama Sky Robo • Twin Rotor System • Twin Rotors counter-rotate reducing mechanical complexity. • Eliminates Torque effects caused by a single large rotor blade • Control and Stability greatly increased • Tail Rotor is not required because one rotor is made to turn faster thus creating a Torque that controls the Yaw axis. • Lower rotor blade and head are controlled by the servo motors. Servo motors control the lower rotor through the swash plate by angling the lower rotor disk downwards or upwards to create an elevator effect. By pitching the disk angle left or right there is an aileron effect. • Stabilizer Bar • Connected to Upper rotor Blade and movement head • Senses the helicopter’s body movements and automatically adjusts the cyclic operation of the top blades to control rudder direction opposite to body motion
