Advantages and Disadvantages of VTOL Drones vs Fixed Wing Drones
VTOL and multirotor drones have several advantages over fixed-wing unmanned aircraft. They require much less space to launch and recover, as they do not need to use a runway. They are suited to applications such as inspection and monitoring where the aircraft must maintain a fixed position for a period of time. They are generally more manoeuvrable than fixed-wing aircraft due to the ability to vary the relative speed of each rotor, thus creating changes in thrust and torque.
The main disadvantage compared to fixed-wing UAVs is the lower endurance. This is due to the fact that VTOL UAVs use their rotors to generate both lift and thrust, therefore requiring more power, whereas fixed-wing aircraft only require their propulsion system to generate thrust, as the lift is generated by the wings.
