Drone chassis

A drone chassis, comprising an external structure that deforms elastically in bending, and furthermore comprising a set of cables connecting at least one support to the external structure, wherein the at least one support is configured to support a functional element of the drone, the set of cables comprising elastic cables that deform elastically in traction under a tensile stress above a threshold, referred to as the natural tensile deformation threshold, the set of cables being attached at several points on the external structure, referred to as attachment points, to hold the at least one support in a stable position with respect to the external structure, wherein the elastic cables are attached under stress by applying, to said elastic cables, an initial tensile stress, and by maintaining the initial tensile stress by attaching to the external structure so that an external force applied to the chassis and generating an additional tensile stress on the elastic cables attached under stress causes a deformation under traction of the cables and a bending deformation of the external structure only if said additional tensile stress exceeds a minimum tensile deformation threshold that is above the natural tensile deformation threshold of the elastic cables.
