Description

Technical Field

[0001] This application belongs to the technical field of aircraft landing guidance design, and particularly relates to a method and system for guiding an aircraft to land on a ship deck. Background Art

[0002] When guiding an aircraft to land on a ship deck, the shipborne guidance computer transmits the guidance deviation detected by the guidance equipment, usually including the altitude deviation and lateral deviation of the aircraft from the ideal glide path, to the airborne control computer through the data link transmission system. The airborne control computer automatically controls the aircraft to land on the ship deck based on the guidance deviation. As Figure 1 shown, it can greatly reduce the workload of the pilot and improve the safety of the aircraft landing on the ship deck.

[0003] For the guidance equipment for guiding an aircraft to land on a ship deck, there are usually satellites, radars, and optoelectronics. Currently, most designs use the guidance deviation detected by a single guidance equipment to automatically control the aircraft to land on the ship deck. However, within different distance ranges, different guidance equipment has different anti-interference capabilities and measurement accuracies. Using the guidance deviation detected by a single guidance equipment to control the aircraft to land on the ship deck is difficult to achieve accurate guidance for the aircraft to land on the ship deck. Therefore, in some technical solutions, the guidance deviation detected by different guidance equipment is switched and utilized within different distance ranges to control the aircraft to land on the ship deck. This technical solution has problems such as inappropriate switching timing of the guidance deviation detected by the guidance equipment and uneven data switching.

[0004] In addition, currently, in order to reduce the risk of data transmission between the shipborne guidance computer and the airborne control computer, a dual-redundancy design is adopted for the data link transmission system, but usually the same transmission frequency is used, which is a similar design and is easily interfered with simultaneously, and cannot effectively ensure the reliability of data transmission between the shipborne guidance computer and the airborne control computer.
