Aircraft simulation platform is the most important supporting technology in the aircraft development process. This simulation platform can be used for validating the design of subsystem and also it provides the necessary data for the Aircraft design. Wind has great impact on the flight parameter. In order to accurately simulate the wind model and calculate the flight parameters
a simulation modeling method for flight parameter simulation platform under wind field environment is established. Firstly
the various sub-systems which affecting flight parameters are analyzed
some mathematical models of the flight parameter simulation platform is established. Secondly
the atmospheric wind field is studied to analyze the impact on its trajectory. Then the model is built in the Simulink toolbox in the Matlab which is based on the principles of hierarchy and modularity
using C MEX S-function for the complex kinetic equations. Finally
when the models have been established
encapsulating models for several subsystem and assembling them for the Aircraft simulation platform based on the unified interface. The simulation tests (including the performance test of a certain gliding Aircraft
the wind influence test of a certain uncontrolled aircraft) prove the simulation capability of the platform
and its calculating step can reach 1 ms. Comparing simulation with field test data of a certain uncontrolled aircraft
it shows that the relative deviation of range is 0.47%
the relative deviation of maximal altitude is 2.1%. Taking relevant standards as a reference standard
it is demonstrated the platform is reliable
meets the engineering accuracy requirements. 2010 IEEE.
