First-Person View (FPV) drones are a class of unmanned aerial vehicles (UAVs) that allow the operator to experience flight from the drone’s perspective through a live video feed transmitted from an onboard camera. These drones are widely used in applications such as aerial photography, racing, freestyle flying, and inspection tasks due to their high maneuverability and immersive control system.
A critical component of any FPV drone is its frame, which serves as the structural backbone supporting all onboard components, including motors, propellers, flight controller, battery, and camera system. The design of the frame directly influences the drone’s performance, durability, and flight efficiency.
FPV drone frames are typically designed to be lightweight yet structurally strong. A lightweight frame is essential because it reduces the overall mass of the drone, leading to:
However, reducing weight must be carefully balanced with structural integrity. During operation, drone frames are subjected to various loads, including motor vibrations, aerodynamic forces, and impact stresses during hard landings or crashes. As a result, materials and geometries are selected to ensure the frame can withstand these conditions without failure.
In addition to structural considerations, modern FPV frames often incorporate protective features, particularly for sensitive components such as the onboard camera. Camera protection is important in FPV applications where collisions are common, especially in racing and freestyle environments.
This project focuses on the design and structural evaluation of a custom FPV drone frame, with particular attention to achieving a balance between lightweight construction and mechanical strength, while integrating a protective housing for the camera.
The FPV drone frame was designed using Autodesk Fusion 360, a parametric CAD tool that allows precise modeling, assembly, and iterative design improvements. The design process began with a conceptual layout of a typical quadcopter frame, followed by the creation of individual components which were later assembled into a complete structure.
The modeling approach was parametric, meaning key dimensions such as arm length, plate thickness, and mounting hole spacing were defined and could be easily adjusted during the design process. This allowed flexibility in refining the frame to achieve a balance between structural strength and weight reduction.
