This is an open access article under the CC BY-NC-ND license (https://creativecommons.org/licenses/by-nc-nd/4.0) Peer-review under responsibility of the scientific committee of the ICSI 2023 organizers Abstract Drones are currently being used in more and more new fields, including those where there are many obstacles that a drone can hit while performing its task. Therefore, the need to prevent a drone from damage when it crashes into an obstacle has arisen and such protection will also enable the use of drones in new applications involving operating in a very small space with a high probability of collision. One of the solutions to this problem is to put the drone into a protective cage. This paper presents the results of load analysis on drone protective cage and the proposed one has a specific structure and consists of an external mesh with specially shaped nodes and topology of mesh elements. The whole cage is suspended on a gimbal type connection that increases the collision capabilities and minimizes the impact of collisions on the drone's behaviour and cage load. The unusual construction of the drone itself, and in particular the arrangement of the drone's propellers, allows us to maximize the operational possibilities. he results show how the loads are distributed throughout the cage and gimbal element and how they affect the drone inside. The tests were carried out both in a simulation environment and on built demonstrators in laboratory conditions and simulated operational conditions. © 2023 The Authors, Published by Elsevier B.V.
