Research On Simulation And Virtual Trial Of Light Aircraft

Light aircraft plays a more and more important role in national defense and civil life field. A kind of flight control system with small volume, light weight, high reliability is required eagerly. So making researches on the light aircraft flight control system is of theory, engineering and economical value.Many aspects are concerned in flight control system. The main modules of light aircraft control system and system design nodus are analysed in detail. Only flight control system ,flying trial data recorder and control law of airborne Information System are studed in this paper .The main tasks are as follows:1 , In autopilot aspect, a new style light aircraft control computer based on DSP.Firstly is designed in this paper. Then we explicate the hardware design in details, include implementing AD convert, extending multiple serial communications and external memory. These incarnate abundance simulation interface, flexible digital interface and serial communication interface. The autopilot based on this computer meets the demand of high performance and miniaturization.2, In flying trial data recorder aspect, Directed against the requirement of flying trial data recording of light aircraft, Analyses the work principle of flying trial data recorder, a design project of flying trial data recorder based on large capacity flash storage is adopted in this paper and implements it in work.3, In addition, studies the flight control of light aircraft, the Riccati method applied to the design of the flight control law of the light aircraft.
