Research On The Design Technique Of The Instructor System Of Carrier-based Aircraft Landing Signal Officer

In the modern war,the combat ability of the aircraft carrier is widely recognized. It is a necessary condition to realize the ocean attack of the aircraft. When carrier-based aircraft complete missions in return for landing, from a height overlooking, the carrier is like a drop in the bucket, making carrier landing great difficulty. In order to assure the security of carrier based aircraft landing, it needs Landing Signal Officer (Landing Signal Officer, referred to as the LSO) of the auxiliary guide. However, the cultivation of a qualified LSO is not easy.Therefore, this paper conducts in-depth study on the LSO instructor system, and provides assist to the LSO training.Based on the introduction of LSO instructor system frequently-used coordinate system,the navigation parameters and control parameters of aircraft navigation, the aircraft kinematics and dynamics model are established according to the aerodynamics, Newton’s law and the moment of momentum knowledge. By using the method of small disturbance linearization, the linear model is decomposed into longitudinal linear model and transverse linear model. On the basis,through the establishment of the servo system,aircraft flight control system is designed completely from the inner ring navigation and outer ring trajectory two angles, and the model of LSO instructor system is completed.After the aircraft model of the LSO instructor system is established, the syllabus of the LSO instructor system started to be studied. The LSO syllabus is designed from the oversll,and is divided into the course of LSO basis, the course of LSO correction and the course of LSO waveoff. LSO based curriculum is designed from the perception variables and LSO basic instructions two aspects; The designs of the LSO longitudinal correction course, the designs of LSO transverse correction course and the designs of the comprehensive rectification course are completed by the simulation of instruction boundary condition and the analysis of correction process; The design of LSO waveoff course is elicited by the analysis of the safe waveoff area and waveoff process. All of these lay the foundation for the research on the design technique of LSO instructor system.The overall structure of the LSO instructor system is designed, including the carrier-based aircraft model, the LSO syllabus, artificial instructor model, student model,curriculum control, plot script, measurement evaluation and the speech system; Each module is designed specificly from the angle of the function, and the method to verify the model is given, and the linkages between each module is analied; After the system design is completed,the specific execution process is descripted in detail and prepares for the LSO training.After the overall researched design of the system is completed, the implementation of the software model is the best proof. This paper finally introduces the simulation development basis of the LSO instructor system; Elaborating the function of carrier-based aircraft software model which include numerical calculation,3D visual display and curve display; Analying the solution process of carrier-based aircraft software model; Designing the LSO curriculum control software module and measurement evaluation software module;Completing the LSO instructor software system.
