A Study On The Model And Simulation Of The Stable Platform In Illuminated Landing System

Nowadays, large ship has been regarded as the most effective integrated offshore platform in the world because of its effective combat capability. To large ship, the carrier-based fighter planes are its most powerful weapon. It was just depended on these fighter planes' effective combat capability that those large ships' groups can be able to navigate in the vast ocean freely and safely.We may say, the pilots working in carrier-based fighter plane are those people who engaged in the most dangerous job in the world. To these pilots, catapult takeoff is comparatively easy and safe. The real ordeal to them is landing on the large ship. Because looked from the sky, the large ship resembles a piece of leave floating on the mighty ocean. The pilot must find the large ship in the distance when he wants to land, so as to affirm the state of warship device. In addition, the mutual communication with other warship machines about the flying state is also necessary. Various uncertain elements (such as the changing flying line, the swaying warship deck...) are produced due to the continued navigation. Because of these uncertain elements, touching down the large ship is more difficult than regular touching down the land. In the process of landing, the most dangerous stage is slide landing. Nowadays, most large ships use lights assist landing device, which help to provide an optic slide runway. However, under the normal circumstances, the sway of large ship always causes the sway of the assistant-landing device. In order to weaken the sway, a stabilized platform is installed for the balance of the large ship. With concern to the stabilized platform, this thesis intends to study the following aspects:At first, this thesis makes an analysis based on the well-known features of Fresnel lighting assistant landing device. On the basis of the systematic structure, it also clarifies the function of stabilized platform and several requirements for the platform, which lay the foundation for the next chapters.Secondly, by studying the motion of ship models, we can obtain the relevant information about the moving features of aircraft and the special moving regularity of kinematics ocean body. By studying large ship's moving features-"six liberty degree moves", as well as stable platform's moving features, we can establish its initial kinematics' models. On the other hand, considering the construction features of platform and the factors caused by the sway of large ship, we may do some amendments and improvements to increase the compensation amount, so as to further perfect the models.Finally, the emulation of various models will be realized under the different environment of the ocean. We may analyze the received moving curve of these models, testify the correctness of their parameters. Compared with widely-used TACAN antenna on the large ship, we can also conclude that there are different kinematics models, when the stable platform is used in the different situation...
