Research On Instrument Carrier Landing System

This dissertation studies further on Instrument Carrier Landing System(ICLS) with the purpose of improving the security of carrier landing system.Firstly, flight procedures for carrier aircraft flying to the air carrier are studied in this paper and the function of Instrument Carrier Landing System in the whole flight procedures is concluded. Then, physical characteristic of natural aircraft is analyzed in carrier landing situation of low dynamics pressure, and Backside control strategy and Frontside control strategy are studied in Backside carrier landing situation.The second important part of this dissertation is the research on Instrument Carrier Landing System. The stabilized platform based on radars is constructed. Then, the whole system configuration for longtitude and lateral system of ICLS is finished with the establishment of motion rule and the design of guidance and control system. Also, digital simulink for this system in Matlab is completed and the reason of the ultimate instability for ICLS is concluded.Finally, microwave carrier landing system is researched. Lateral system with automatic path definition is studied specially, and guidance laws are designed.This dissertation contributes to academic research and engineering application of Instrument Carrier Landing System.
