Below are general answers on typical components of fixed-wing drones from the list of GAO Tek’s fixed-wing drones. 

 

Electronic Components 

  • Microcontroller: The brain of the drone, responsible for processing sensor data and controlling the actuators (such as servos and motors). 
  • Sensors: These include accelerometers, gyroscopes, magnetometers, and barometers. They provide the flight controller with data on the drone’s orientation, speed, altitude, and direction. 
  • GPS Module: Provides geolocation and time data, crucial for navigation and maintaining the drone’s position. 
  • Battery: Usually lithium-polymer (LiPo) batteries are used due to their high energy density. The battery powers the entire drone, including the propulsion system and electronics. 
  • Electronic Speed Controllers (ESCs): These regulate the power from the battery to the motors, controlling the speed of the propellers. 
  • Radio Transmitter/Receiver: Enables communication between the ground control station and the drone. Operates on specific frequencies (e.g., 2.4 GHz, 5.8 GHz) and is used for controlling the drone and transmitting telemetry data. 
  • Telemetry Module: Provides real-time data exchange between the drone and the ground control station, including flight status, battery levels, and GPS position. 
  • Cameras/Sensors: The payload can include high-resolution cameras, infrared cameras, multispectral sensors, or LiDAR sensors depending on the drone’s mission. 
  • Gimbals: Motorized systems that stabilize and control the orientation of cameras or sensors to ensure clear images or accurate data collection. 
  • Onboard Computer: More advanced drones may include a small onboard computer for processing sensor data, running advanced algorithms, or performing autonomous tasks. 
  • FPV (First Person View) System: Includes a camera and video transmitter that allow the pilot to see from the drone’s perspective in real-time. 

Software Components 

  • Autopilot Software: Manages basic flight functions such as takeoff, navigation, and landing. Popular examples include ArduPilot, PX4, and proprietary software. 
  • Stabilization Algorithms: Software routines that use sensor data to maintain stable flight by adjusting control surfaces or throttle automatically. 
  • Mission Planning Software: Allows operators to pre-program flight paths, waypoints, and mission parameters. Examples include QGroundControl and Mission Planner. 
  • Telemetry Monitoring: Software used on the ground station to monitor the drone’s status in real-time, including its position, speed, altitude, and battery life. 
  • FPV Software: Software for live streaming video from the drone to the operator, often integrated with VR or FPV goggles. 
  • Protocol Stacks: The software that manages communication between the drone and the ground station, including the transmission of control signals and telemetry data. 
  • Image/Video Processing Software: Used to analyze data collected by the drone, such as stitching aerial images into maps or analyzing sensor data for patterns. 
  • AI/ML Algorithms: Some drones utilize artificial intelligence for tasks like obstacle detection, object tracking, or autonomous decision-making. 

Mechanical Components 

  • Fuselage: The main body of the drone that houses the electronic components, battery, and payload. 
  • Wings: Fixed wings provide the lift necessary for flight. They are designed for efficiency and stability and may include ailerons for roll control. 
  • Tail Assembly: Typically includes horizontal stabilizers (elevators) and vertical stabilizers (rudder) for pitch and yaw control. 
  • Motor(s): Electric motors drive the propellers. Fixed-wing drones often have one or more motors depending on their design (e.g., pusher or tractor configuration). 
  • Propeller(s): Propellers convert the rotational motion of the motors into thrust, enabling the drone to move forward. 
  • Ailerons: Located on the wings, these control the roll of the drone. 
  • Elevators: Located on the horizontal stabilizer, these control the pitch of the drone. 
  • Rudder: Located on the vertical stabilizer, this controls the yaw of the drone. 
  • Fixed Landing Gear: Some drones have simple fixed landing gear, such as skids or wheels, for takeoff and landing. 
  • Retractable Landing Gear: In more advanced models, landing gear may retract during flight to reduce drag. 
  • Gimbal Mounts: These mounts stabilize and control the orientation of the payload (like cameras) during flight. 
  • Fixed Mounts: Simpler drones may use fixed mounts for payloads, providing less flexibility but greater simplicity. 
  • Heat Sinks/Fans: Used to dissipate heat from the motor, ESCs, or other components that generate heat during operation. 
  • Servos: Small actuators that move the control surfaces (ailerons, elevators, rudders) based on commands from the flight controller. 
  • Pushrods/Cables: Mechanical linkages that connect servos to control surfaces.
