3.9. THE FLIGHT
Figure 3.18: Basic flight principles
For redundancy, the Intel® Falcon™ 8+
UAV has eight propellers. Four propel-
lers turn clockwise, four turn counter-
clockwise as shown in the image. This
eliminates the torque of the single pro-
pellers as much as possible. Neverthe-
less, the UAV has no inherent stability,
and a control circuitry needs to con-
stantly monitor and control the UAV to
keep it stable.
By varying the turn rate of the different
propellers, there are four controllable
directions along three axes on which the
UAV can be controlled:
• Roll axis: movement to the left or
right. For example, when rolling to the
right, the propellers of the left motor
rail are turning faster than the propel-
lers on the right motor rail.
• Pitch axis: movement forwards or
backwards. For example, to fly for-
ward, the four back propellers turn
faster than the four front propellers.
The UAV takes a certain angle along
the pitch axis and flies forward.
• Yaw axis: adjust the heading of the
UAV. When yawing to the left (clock-
wise), all left turning propellers turn
faster than the right turning propel-
lers.
• Thrust: ascend or descend along the
yaw axis. All propellers turn faster or
slower to ascend or to descend.
