Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of aircraft guided landing design, and specifically relates to a method and system for guiding an aircraft to land on a ship deck. Background Art
[0002] When an aircraft is guided to land on a ship deck, the onboard guidance computer transmits the guidance deviation detected by the guidance equipment, which usually includes the height deviation and lateral deviation of the aircraft from the ideal glide path, to the onboard control computer through the data link transmission system. The onboard control computer automatically controls the aircraft to land on the ship deck based on the guidance deviation. Figure 1 As shown, it can greatly reduce the pilot's workload and improve the safety of aircraft landing on the ship deck.
[0003] The guidance equipment for guiding the landing of aircraft on the deck of a ship usually includes satellites, radars, and optoelectronics. Currently, most designs use the guidance deviation detected by a single guidance device to automatically control the aircraft to land on the ship deck. However, different guidance devices have different anti-interference capabilities and measurement accuracy within different distance ranges. It is difficult to accurately guide the aircraft to land on the ship deck by using the guidance deviation detected by a single guidance device. For this reason, some technical solutions are designed to switch the guidance deviations detected by different guidance devices 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 device and uneven data switching.
[0004] In addition, at present, in order to reduce the risk of data transmission between shipboard guidance computers and airborne control computers, a dual-redundancy design is adopted for the data link transmission system, but the same transmission frequency is often used. It is a similar design and is easily interfered with at the same time, and cannot effectively guarantee the reliability of data transmission between shipboard guidance computers and airborne control computers.
