Further, the spray control system includes: an air drop operation platform and a spraying switch;

the air-drop operation console is used for sequentially opening a rear cargo door and a spraying switch of the airplane body.

Furthermore, the air drop operation console can acquire the current flight parameters and environmental parameters of the airplane, calculate and determine the time for opening the rear cargo hold door and the time for opening the spraying switch.

Further, the weight and size of the fire extinguishing shelter filled with the fire extinguishing agent must not exceed the loading weight and size requirements of the aircraft body.

Furthermore, the center of gravity position of the fire extinguishing shelter filled with the fire extinguishing agent must not exceed the requirement of the center of gravity of the airplane body.

Furthermore, the flying height and flying speed of the airplane executing the fire extinguishing task must ensure the flying safety and the fire extinguishing effect to the maximum extent.

Further, the spray switch is arranged at the bottom of the face of the fire extinguishing agent square cabin close to the rear cargo cabin door.

Has the advantages that: the adoption of large fire-fighting airplanes for forest fire-fighting becomes the best choice. The land of China is wide, the forest coverage area is large, and meanwhile, a large number of transport planes are equipped in China, so that after the existing aircraft is refitted and a special fire extinguishing agent shelter is additionally arranged, a powerful weapon can be provided for forest fire extinguishing in China.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The aircraft body can be an air force active large-scale transport plane, a fire extinguishing agent square cabin can be additionally arranged without modification, the fast loading and firm fixing of the square cabin can be realized, the air drop control console can be used for opening and closing the rear cargo cabin door, the current flight parameters and the environmental parameters of the aircraft can be obtained, and the time for opening the rear cargo cabin door and the time for opening the spraying switch can be determined by additionally arranging special calculation software.

The fire suppressant shelter of the present invention may optionally be retrofitted from large military containers or designed separately. Can be in the form of one or more fire suppressant compartments interconnected. In order to ensure that the gravity center position of the airplane is within the gravity center position requirement range in the airplane, if the fire extinguishing agent shelter is a shelter, a partition plate and a partition plate switch are added in the shelter; if a plurality of fire extinguishing agent square cabins are mutually connected, a connecting port and a switch are arranged between the square cabins.

The fire extinguishing agent square cabin is provided with a fire extinguishing agent injection opening and a switch, and the spraying switch is arranged closest to the rear cargo cabin door. The spray switch may be cross-linked to the aerial delivery console and may be manually operated.

The forest fire-extinguishing aircraft body can be an air force active transport aircraft or a civil transport aircraft, and the fire-extinguishing agent shelter can be refitted from a large military container or designed independently.
