However, the primary innovation of our project is the use of a mesh structure, which provides a lightweight casing while maintaining high durability. This allows our drone to be more efficient and achieve a longer flight time.

4.2. Drone strength analysis: The drone strength analyses were carried out in the Ansys Workbench software environment. When choosing the program for analysis, we took into account the multifunctionality of the program and out know-how of it. In the initial phase, the model employed for stress simulations underwent a comprehensive simplification process. Unnecessary rounding and minor, non-significant holes were eliminated to advance the process and streamline the execution of stress simulations.

A finite element grid was then applied to the simplified model in order to divide the model into interconnected elements. The mesh consists entirely of elements of the TET10 mesh with dimensions not exceeding 5mm. During the strength analysis of the drone, certain important boundary conditions were identified that were crucial for the precise assessment of its strength. Below are the details of these conditions: • Standard Earth Gravity: 9806.6 mm/s². • Fixing at the points of attachment to the gimbal.
