According to the thrust vector control requirements of fast turn of the missile vertical launching,this design carries out the force analysis of the jet vane which is in the high temperature and high speed jet stream,and calculates the normal force which is generated by the vane,thus calculates the area of the jet vane.At the same time,according to the aerodynamic theory and engineering experience,this design analyzes and calculates the aerodynamic shape of the jet vane.As a result,two types of jet vane are designed.On this basis,through the use of a fluid analysis software FLUENT,both of the two jet vane are simulated and get a jet vane which is more suitable for the practical applications.
