Table 3

The contrast between tilt-rotor and tilt wing UAVs.

TypeFeaturesStructural aspectsManoeuvre/control

Tilt-rotor type, [20, 21]Endurance, range, economical, functional, and manoeuvrabilityTwo sets of motors, one set for vertical movement, and the other set for horizontal movement(i) Provide thrust both laterally and vertically
(ii) Direction can be changed using a tilting mechanism
(iii) Capability to manoeuvre in remote areas with increased efficiency of the aircraft in cruising forward as well
Tilt wing type, [26]Range, endurance, payload carrying capacity, and maximum forward velocityControlled by actuators(i) Reduced transition time
(ii) Enhanced stability
(iii) Reduced dead weight for optimizing the flight conditions to improve the aircraft usage in all kinds of aircraft flying mode
