## *5.3.2 Concept generation*

1.Fixed wing UAV

Fixed-wing Static and fixed-wing aerofoils are predefined for UAVs. To conduct its field performance, this type of UAV requires a take-off and landing field. During the field performance stage, they also have high lift devices such as aps and slats to produce lift. The elevator is used to turn the roll over, the ailerons

are used to pitch, and the rudder is used to produce yaw. The detecting system and autonomous avionics are mounted in the fuselage.

2.Rotary wing UAV

To manage the attitude and position in three-dimensional space, rotary wing UAVs have numerous rotors and propellers pointing upwards, resisting the aircraft's weight, horizontal propulsive force, and other forces and moments. Rotary-winged UAVs exist in a variety of rotor configurations, including helicopters, quadcopters, hexacopters, and other unique designs. The ability to execute vertical take-off and landing (VTOL) as well as hovering and rapid maneuvering are the most distinguishing features of rotary-wing UAVs. The rotors' torque and thrust regulate the UAV's movement, which includes yaw, pitch, roll, and throttle. The detection equipment will be installed beneath the wing.
