[0002] Small type helicopter is a kind of light helicopter that can carry 2-3 people, uses piston engine as power, and the maximum flight weight is about 900kg, and is widely used in city patrol, flight training, aerial photography and other aspects. In recent years, with the progress of science and technology and the development of electrical automation and other fields, unmanned plane gradually becomes popular. One of the unmanned planes is to use mature manned helicopter for unmanned modification, install professional flight control and control system, and various avionics and data transmission equipment, so as to have automatic flight capability.

[0003] The manned helicopter (such as small) is modified into unmanned plane, which needs to remove the original instruments, seat and control system on the helicopter, and replace the flight control system, control system (rudder), electrical and mechanical system (monitoring the state of the helicopter) and data communication system required for unmanned driving. In addition, in order to meet different use requirements, different professional equipment needs to be installed on the helicopter, such as aerial photography, thermal imaging, spraying system, etc. The weight, installation position and other of these additional task loads are completely different, which causes the gravity center of unmanned helicopter to change with different task loads. If the gravity center cannot be effectively restored within the applicable range, it will affect the flight performance and flight safety. The conventional method is to increase the weight (lead bag) on the helicopter to adjust the gravity center back. However, the lead bag not only adjusts the gravity center, but also increases the weight of the aircraft, which causes the original payload of the helicopter to be wasted, and sacrifices part of the performance and flight time, which is an adverse effect.

[0013] Further, the adjustable gravity center equipment support further comprises a left fixed support and a right fixed support.

[0014] The bottom end of the rear baffle is fixed on the cabin floor of the helicopter through the left fixed support and the right fixed support.

[0015] Further, the double-layer support further comprises a second layer equipment pulling track.

[0016] The second layer equipment pulling track is arranged on the second layer plate, so as to facilitate the arrangement of the unmanned modification equipment of the helicopter.

[0017] Beneficial effects:

[0018] The device can adjust the gravity center of the whole support assembly by adjusting the position of the mobile lithium battery pack, and can quickly adjust the gravity center of the helicopter to meet the flight requirements when the aircraft is configured with different task loads, and the gravity center is stably locked.
