Abstract
In order to enhance the fidelity of fight dynamic system simulation, this paper, according to the wind fields in practice, concerns mainly in the influence of down-burst and atmospheric turbulence, and proposes their mathematical models. To calculate out the dynamic turbulence, this paper purposed a new modeling method, based on the model of Von Karman which can not be used to simulate directly,instead of the model of Dryden before. By rationalizing Von Karman mode, the atmospheric turbulence is generated in real time to calculate out filter parameter. The analysis in frequency domain and simulation result in time domain show that this model has the better statistical characteristic than the Dryden 3-D model, and solve the realization problem in simulation of Von Karman model. The numerical analogue algorithm in this paper could be used in atmospheric dynamic motion equation, in order to make the simulation more reality in wind field, and it has some practical effect to the development of simulator.
