Abstract


The eternal theme of flight safety of civil aviation transport . With the improvement of civil aviation air-ground data link system , the integration of real-time monitoring technology research and application for aircraft security state open space conditions , and also provides the necessary platform foundation is based on the real - time air-ground data link communications flight reproduction technology . In this paper, the ACARS system that combines visual simulation technology , and to build flying real-time simulation platform reproduction . Real - time flight visual simulation system based on this platform , technical problems , and to provide the necessary technical support for building air-ground integration of flight visual simulation of real-time monitoring system . For ACARS data characteristics , combined with real-time requirements , using a first-order differential singular point removal method , the effective removal of abnormal data . ACARS data can not meet the requirements of aircraft attitude the smoothness and flight trajectory continuity in the actual flight simulation process , characteristics , and to improve the authenticity of the visual simulation system in flight simulation experiment comparing linear interpolation , quadratic interpolation , three spline interpolation and fitting algorithm , the system flight data interpolation method . Cubic spline interpolation to provide a reasonable compromise between flexibility and computational speed , only need a small track data and attitude data to depict the real-time flight path . Combined with particle system modeling method , respectively. Aircraft plume model and cloud model to enhance the realism of the simulation system ; plume modeling process , selection of appropriate lighting and fog effect ; using a two-stage algorithm cloud rendering , improved real-time .
