Abstract

The invention discloses a wing connection structure of a sensor drone, the wing and the drone. The connection structure comprises: a plurality of stepped holes, a plurality of connecting holes, a plurality of connectors and a plurality of blocking elements; a plurality of steps The holes are distributed on the skin along the edge of the wing frame and avoid the antenna unit. The large diameter end of the stepped hole passes through the glass fiber board and the foam board in turn, and the small diameter end passes through the main bearing plate; a plurality of connecting holes are distributed on the wing. on the edge of the skeleton and correspond to the stepped holes one-to-one; each connecting piece fixes the main bearing plate of the skin on the wing skeleton through a stepped hole and a connecting hole; each blocking element is filled with a stepped hole holes to complete the skin surface. The invention can meet the requirements of the structural integrity of the wings under the premise of ensuring that the antenna components inside the wings can work normally, so that the connection process between the skin and the skeleton is feasible, and the connection strength meets the requirements.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and more particularly, relates to a wing connection structure of a sensor unmanned aerial vehicle, a wing and an unmanned aerial vehicle. Background technique [0002] The sensor UAV contains sensor components, which can be scanned within a certain angle range and used for the sensor UAV early warning aircraft platform. Therefore, it is necessary to ensure that the wave transmission performance within the working radiation range of the UAV meets the requirements, and the reflective layer is electrically continuous. The wing structure must meet the integrity requirements, the connection process between the skin and the skeleton is feasible, and the connection strength meets the requirements. The sensor components of traditional sensor UAVs are independent of the body components, limited by the requirements of wave transmission, the antenna aperture area is relatively small, and th...
