Developing Aerodynamics or Fluid Mechanics virtual experiment software by applying modern CFD[3] and computer technologies, letting students carry on experiments under virtual circumstances, is an effectual approach to solve the above problem, and development and application of virtual experiments will influence practical teaching revolutionarily.
Based on virtual environments (simulation platforms), virtual experiments are focusing on interactive operations and simulation of experimental results[5].The emergence of virtual experiments helps to develop students' learning interest, broaden the students' knowledge, and boost theoretical knowledge studying effectively.
In order to enhance emulational degree, the numerical simulation results based on computational fluid dynamics were corrected by consulting the real experimental results and a variety of professional documents.
For example, if the air flowed through the wing with sound effects, and equipments were introduced with a voice narration, the simulation effect would be better.

The dynamic simulation and analysis show the interferential moment of the nose and main body can cause disadvantageous “body flutter”.
Simulations and Analysis The simulation is done to analysis the motion coupling of the nose and the main body with four different conditions
The simulations were done with the nose weight of 10kg, 15kg and 20kg, the other parameters is the same as (1).

The behaviour is studied using downburst wind field data obtained from a computational fluid dynamics (CFD) model.
Using a downburst wind field based on CFD analysis by Hangan et al. [4], Shehata [5] identified several critical downburst configurations that resulted in peak axial loads developed in the angle section members of a guyed lattice tower.
The downburst wind field used in the current study was developed through computational fluid dynamic (CFD) analysis by Hangan et al. [4].
For a complete description of the CFD model, the reader is referred to Hangan et al. [4], Shehata [5], and Shehata et al. [6].
