Background

In the hovering observation stage of the amphibious aircraft for executing a fire extinguishing task or the searching and rescuing stage of the amphibious aircraft for executing a water rescuing task, an observer on the aircraft needs to observe the fire condition below the aircraft or the marine condition through the convex spherical observation windows on the two sides of the aircraft body. The flame combustion condition can pollute the view field of the spherical observation window, salt separated out on the sea can also pollute the view field of the spherical observation window, and whether the visual field of an on-board observer is clear or not is directly related to whether the fire extinguishing and water rescue tasks of the amphibious aircraft can be successfully completed, so that the key point is that a set of cleaning system is equipped for the spherical observation window.

At present, an amphibious aircraft windshield cleaning system is designed for plane windshield glass of an aircraft, and a relay is added in consideration of the workload of a pilot, so that the function of automatically controlling the amount of cleaning liquid is realized. For spherical glass such as an observation window, it is difficult to spray a cleaning liquid on all glass surfaces by using a windshield cleaning system, and it is also difficult to wipe the glass surfaces clean with a conventional wiper. There is therefore a need for a cleaning system for spherical windows.
