Lift Generating
The most
important component of UAVs is Wing at fixed wing UAV and rotor at multi-rotor
UAV that
generate lift to raise UAV up.
How UAVs Raise Up?
The theory is the same in both fixed wing and multi-rotor, the main idea for generate lift is make section of wing and rotor have airfoil
Depend
on the rule that describe the relation between pressure and velocity PV=constant,
therefore in the upper surface of airfoil have length more than lower surface
of airfoil, thus to arrive air at trilling edge at the same time the flow in
the upper surface will be speeder than lower but pressure will be in lower more
than upper according to PV=constant, therefore we have pressure raised UAV up
and we can control for this amount of lift force but increase and decrease the
velocity of UAV.
