Research On Fly-By-Light Realization Technologies

To satisfy the requirements of Fly-By-Light (FBL) technology development, this thesis was devoted to the research on key realization technologies of FBL flight control system. This thesis analysed the mechanics of fibre-optic transmission system, and the infrastructure and operating principle of Point-to-Point Servo in FBL, also developed a set of Analogue Single-channel Fibre-optic Transmission System and Point-to-Point Servo in FBL. Finally, strict performance test was carried out. The thesis mainly consists of five chapters.Chapter 1 introduced the development of Flight Control System and the background and motivation of FBL. The critical technologies and research status of FBL were also represented briefly.Chapter 2 introduced the infrastructure and operating principle of fibre-optic, and discussed several typical modulation demodulation systems. Based on Pulse Frequency Modulation (PFM), this chapter developed a set of Analogue Single-channel Fibre-optic Transmission System.Chapter 3, Chapter 4 and Chapter 5 detailed the infrastructure, operating principle and design scheme of Point-to-Point Servo in FBL, including hardware circuit and software design, final performance tests and Instrument Carrier Landing System simulation showed that this system had excellent real-time performance and capability of anti-interference, and verified the feasibility and reliability of Point-to-Point Servo in FBL application.
