Abstract

The invention relates to a compact unfolding and folding device for an airborne radar large-array-plane antenna, and the device comprises a frame, a synchronizing shaft, a transmission rod and a driving device, wherein the driving device and the frame are arranged on a base, and the synchronizing shaft is arranged on the frame and can rotate relative to the frame; the transmission rod is in vertical transmission connection with the synchronizing shaft, the synchronizing shaft is connected with an antenna array plane, and the driving end of the driving device drives the transmission rod to movein the axial direction and drives the synchronizing shaft to rotate so as to unfold and fold the antenna array plane. The transmission rod is driven by the driving device to move in the axial direction, and then the synchronizing shaft is driven to rotate to achieve unfolding and folding of the antenna array plane, and enabling the antenna array plane to be attached to a belly of an airplane to the maximum extent. Moreover, the device is low in cost, is simple in motion, is high in reliability, is high in automation degree, and can meet the requirements of unfolding and folding work of the airborne large-array-plane antenna.

Description

technical field [0001] The invention relates to an antenna unfolding and retracting device, in particular to a compact unfolding and retracting device for an airborne radar large array antenna. Background technique [0002] The airborne radar antenna needs to be mounted on the belly of the aircraft. When the radar is in flight, the antenna should be deployed to the working position or angle, away from the belly of the aircraft, so as to avoid the influence and occlusion of the electrical performance of the antenna by the fuselage. Next, the radar antenna is retracted into the cabin or close to the belly of the aircraft to avoid collision damage between the antenna and the ground or affect the take-off and landing of the aircraft. For the unfolding and retracting action of the airborne radar antenna, it usually needs to be realized with the help of the antenna retracting device. [0003] The traditional small lifting device is only suitable for small array antennas, and it c...
