Flight parameter computing platform is the most important supporting technologies of the aircraft development process. This computing platform can be used for validating the design of subsystem and also it can provide the necessary data for the aircraft design. Wind is a key influencing factor of 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. First

based on the several influence factors of the flight

some mathematical models of the flight parameter simulation platform is established. Second

it modeled on the Simulink toolbox in the Matlab which is based on the principles of hierarchy and modularity and using C MEX S-function for the complex kinetic equations. Then after the models are established

encapsulating this models for several subsystem and assemble them for the flight parameter computing platform based on the unified interface. The simulated tests (including the performance test of a certain gliding aircraft

the wind influence test of a certain uncontrolled aircraft) prove computing capability of the platform

and its calculating step can reach 1 ms. Through comparing with simulation and field test data of a certain uncontrolled aircraft

it shows that the relative deviation of range is 0.44% ，the relative deviation of maximal altitude is 1.8%. Taking QJ 1997-90 as a reference standard

it is demonstrated the platform is rationality and reliable

meets the engineering accuracy requirements.
