With the aim of real-time adjusting the angle of a ship's multi blade propeller and improving its application performance, the real-time adjustment technology of the ship's multi blade propeller angle under jet disturbance is studied. Using collaborative jet control technology, the three-dimensional Reynolds averaged N-S equation is used as the control equation to solve the state vector, flow vector, dissipation flux vector, etc; Using the above parameters to analyze the force acting on the shape of the collaborative jet propeller and obtain the force generated by jet disturbance; Based on this force, the momentum coefficient of the nozzle and the power coefficient of the air pump are calculated, and the influence of these parameters on the collaborative jet is analyzed. Based on this influence, the angle of the ship's multi blade propeller is adjusted. The experimental results show that the data obtained by this method has high reliability. Using this method to adjust the multi blade propeller angle of a ship under jet disturbance in real-time can significantly improve the performance of the propeller.
