چکیده مقاله:

 

Common practice in marine vessels such as surface ship and submersible vehicle is utilizing the propeller and motor to generate the trust. The performance of the vehicle is directly influenced by propulsion system efficiency. To increase the efficiency of propulsion system, the propeller design must be taking into consideration.This paper presented the contra rotating propeller design based of propeller vortex lifting line theory. The propeller is designed for a surface ship according to parameters in Benjamin-Y.-H.-Chen [1]. To achieve needed thrust, the parametric design methodology is used, and then the best Revolution speed and diameter for both propellers are selected. After the code is validated with forward propeller hydrodynamic parameters, the after propeller will be designed by two methods. The first method will be done by forward and after propellers torque equalization. In thismethod both diameter and linear velocity will be changed. The linear velocity changing domain is between 8.825 and 9.42 m/s because of axial distance influence. In the second method efforts will be done to equalize the circulation. In this method also the propeller diameter and linear velocity will be changed as same as 1st method.
