After the mission is over, the lifting system drives the mission load back to the original position.

(2), the present invention supplies power to the task load and the aircraft battery through the solar panel installed in the center of the fuselage, which not only ensures the long-term operation of the aircraft, but also makes reasonable use of resources;

(3) The present invention is equipped with an energy management system, which controls the solar panels to convert solar energy into electrical energy, part of which supplies power for the task load, and part of which supplies power for the electrical system; Location.

(4), the navigation flight control system and the task load of the present invention are connected with the ground station system through the data link, and the working conditions of the drone are monitored through the ground station system, and the remote control can be performed through the ground station system; at the same time, the task load After the aircraft arrives at the designated position, it works and monitors the battlefield.

(5) After the present invention reaches the designated position, it will automatically land through the program set before the ground station system. The retractable and foldable landing gear can automatically adjust the height according to the landing position, so no matter where it lands, it can Leveling is carried out through the adjustment of the landing gear, so that the aircraft lands smoothly and reaches the designated position; and the retractable and foldable landing gear can be folded during transportation to reduce the occupied space.

The invention has stronger environmental adaptability, longer voyage and can be stationed on the battlefield for a long time and perform reconnaissance and defense tasks. The device can supply power to mission loads (radar, horn, photoelectric pod and related weapon systems, etc.) for a long time. The retractable and foldable landing gear can ensure that it can adapt to different landing sites. The UAV can be remotely monitored and sent in real time through the ground station system. Control commands to achieve the purpose of long-range reconnaissance and defense.
