Research on Optimization Design of Fully Parameterized Pump-Jet Propulsion

A pump-jet propulsion system is composed of rotor, stator, and duct. The stator has the front type rear type; conduit also acceleration deceleration two forms. It difficult to design evaluate performance a because its complex structure many changes in component parameters. Due limitation time cost process system, it find optimal scheme space. However, under guidance an optimization algorithm, automatic method can fill space with large number schemes. In this paper, geometry reconstruction technique, hydraulic evaluation technique are combined realize automation whole process. Firstly, geometric modeling completed by full parametric method, then hydrodynamic calculated based on numerical simulation technique. radial parameters fully configuration were selected as variables, hydro-dynamic was optimized objective function. Finally, constructed using global intelligent algorithm. This study provides theoretical basis technical for calculation system.
