The Model And Simulation Software Design Of Aircraft Maneuvering Track

The computer visual simulation technology is a kind of graphical simulation technology,which is based on numerical simulation to express the process or result of numerical simulation with graphics and animation.The flight scene simulation is a typical application of computer visual simulation technology,which can provide an efficient and visual problem solution on aircraft maneuvering flight research.The acquisition of aircraft maneuvering flight path is an important research topic of flight scene simulation,If the model of aircraft maneuvering track is established,and the aircraft maneuvering track is acquired by visual simulation.It's applied to the research of ECM,the air force can effectively obtain the enemy aircraft RCS value,which can provide reference for the effective attribute judged the enemy target in the process of operation and reliable data support for better playing ECM effectiveness.The paper mainly uses three degrees of freedom and six degrees of freedom method,based on analyzing the airframe structure and dynamics relations,has established aircraft maneuvering track particle model with three degrees of freedom particle model and six degrees of freedom flight dynamics model,and uses Matlab/Simulink and Flight Gear software.It has set up a Matlab/Simulink+Flight Gear simulation platform,has obtained the six degree of freedom track data of the aircraft during the tactical maneuver flight,and has proposed the calculation method of the RCS value with the simple model splicing and the FEKO software in the aircraft maneuver flight.Then,with the VC++6.0,MS3 D,open graphic library Open GL as a software development environment,based on object-oriented programming ideas,detailed introduces track realization process in the drawing track part of the aircraft maneuvering track simulation software and realization method of the 3D plane model in the 3D scene simulation part,the aircraft tail flame,terrain,sky,fog effect,flight driving,and also introduced the realization method of designing the RCS calculation software.It has finally completed the aircraft maneuvering track simulation software.It is proved that the model of aircraft maneuvering track can meet the needs of research.And the flight track data,which has acquired by simulation,can be in good agreement with the track data,which has produced by the actual maneuvering flight of aircraft,the two kinds methods of calculating the RCS value can be complementary to each other in the aircraft maneuvering flight,and can obtain more accurate RCS values.The aircraft maneuvering track simulation software has completed the development and testing work,which can automatically generate scientific planning flight path according to the flight demanding,and realize the track simulation,which can display aircraft attitude and position change in maneuvering flight and display flight scene fluently and vividly.It has realized the real flight simulation.It can also calculate the RCS value of aircraft maneuvering flight accurately.The result has higher military application value.
