A non-driven axle motor integrated hydraulic pump jet propulsion design method model is

The present invention discloses a method of designing a hydraulic model shaftless integrated motor-driven pump jet propulsion, it may be designed with seven leaves large open water efficiency paddle quite skewed, lower radiated noise, fully integrated motor and pump discharge pusher . Hydraulic pump fluid channel selection and design parameters, parameterization front and rear of stator vanes impeller ternary reverse design, the pump discharge without air gap open water performance check, integrated motor propulsion jet pump, cavitation, noise performance and strength correction nuclear. The present invention contemplates a pump by the motor stator embedded hypertrophic duct, an annular motor rotor, the air gap, the stator and the rear front of an impeller discharge. 0.589 propulsive efficiency, power 3.7MW, can promote the submersible 16 knots. Leaf blades of the stator 13, the number of blades of the impeller blade 9, are used NACA16 airfoil thickness distribution, and the impeller has a highly skewed. The present invention can be directly used to achieve underwater vehicle shaftless electric propulsion, also apply to the design method of jet pump shaft and rear torpedo integrated motor stator type spray pump design.
