Digital simulation of pressure on a rudder along with the velocity of a missile

In order to secure a highpressure source for the operation of the rudder, a punching rudder is generally used in anti-tank missiles. Its key characteristics are that the flow velocity is used of to produce a high pressure for rudder operation when an anti-tank missile is flying. Because the velocity varies in the flight of an anti-tank missile, the pressure in the pump of the rudder is also changing. It is of significance to calculate the pressure in the design of rudders or anti-tank missiles. A method of calculating three-dimensional Navier-Stokes equations was presented. The appropriate range of velocity of anti-tank missile flight was discussed.
