Aerodynamic Parameters Calculation and Aerodynamic Characteristics Analysis of High-altitude Gliding UUV

Based on the status that the speed and range of unmanned underwater vehicle(UUV) can not be greatly improved at the same time,this paper advances the conception of high-altitude gliding unmanned underwater vehicle and makes a simple design on the overall layout of it.On this basis,in order to analyze its aerodynamic performance,we estimate its lift coefficient,drag coefficient,pitching moment coefficient,heading static derivative,dynamic derivatives and manipulation derivatives,and draw their curves with the method used on plane and missile design.After this,the lift-drag ratio and stability was analyzed.The results show that this UUV is stable and it has a large lift-drag ratio.We can draw a conclusion that this UUV has a good aerodynamic performance.
