Modeling And Simulation Of Aircraft Power Systems (radar Section)

The development of Computer and Calculation Technology promote fast progress of the technology of modeling and computer simulation. The simulation technology has become an independent subject, which is undergoing fast development now and being used in all sorts of science research fields. In national defence science and technology field, simulation technology has become a means to save investment, enhance efficiency and been used as a precursor technology in manufacture and experimentation.After the theory of the More Electric Aircraft Power Supply System is proposed, higher reliability is needed for the Aircraft Power Supply System. Presently the performance test of the Aircraft Power Supply System still relies on manual methods, which cause a waste of manpower, material resources and time. As the modern computer technology develops, computer simulation technology which uses computers as the tools of simulation modeling and simulation experimenting has been widely applied in the fields of scientific research and engineering technology. If we can establish a mathematical model which reflects the capability of the Aircraft Power Supply System and can be simulated in various conditions, then the actual Aircraft Power Supply System can be replaced by this model. The model can also show the influence on the Aircraft Power Supply System when there is a change of the aircraft load, so kinds of accidents can be avoided.This project which is to develop an Aircraft Power Supply System comes from an Aircraft Industry Corporation. It includes the part of power supply and load part. The part of power supply consists of the main power supply and the power supply in emergency. The load part consists of Single phase aviation static inverter, Three-phase aviation static inverter, Hydraulic Pressure System, Radar system and etc.Firstly, this paper introduces the concept, the classifications and methods of...
