technical field

The invention mainly relates to the technical field of aerial refueling, in particular to an aerial refueling lamp with concealed refueling and a manufacturing method thereof.

Background technique

The aerial refueling light is used to provide the aircraft with the lighting required for aerial refueling, and can illuminate the refueling nozzle of the aircraft and the refueling drogue of the tanker in the aerial refueling docking area.

With the development of aviation technology, aircrafts have higher and higher requirements for lighting equipment, and lighting equipment is developing in the direction of small size, low power consumption, high reliability, long life, and stepless dimming.

At the same time, the external lighting technology compatible with the night vision imaging system (NVIS) also gradually improves the overall performance of the aircraft. Aircraft lighting products that meet night vision compatibility are the main method to obtain night combat capabilities. Without relevant design, it cannot meet the night vision compatibility requirements, resulting in pilots being unable to effectively identify targets, affecting flight safety, and unable to meet the needs of night combat and training.

The current aircraft refueling lights do not have a concealed mode, which is the reason for increasing the risk of exposure when the aircraft is refueling in the air at night, which affects the night combat capability of the aircraft and cannot meet the needs of the aircraft for all-weather operations.

Therefore how to design a kind of refueling lamp that can keep concealment when refueling in the air is one of the urgent designs that air refueling needs at present.
