Embodiment 1

[0094] Such as figure 1 As shown, the design method of a database-based water jet propeller disclosed in this embodiment, the specific implementation steps are as follows:

[0095] Step 1: Establishment of the pump model database.

[0096] Using VB programming language, according to the pump type and its characteristic parameters, the blades corresponding to each pump type are divided into multiple cross-section layers, and the coordinate points corresponding to the blade shape of a single cross-section layer are input into the program and saved, and a single cross-section is fitted by SolidWorks The coordinate points of the blade shape generate a single cross-sectional blade shape graphic. Draw the shape graphics on all cross-sections into the same picture to form a graphics file and save it in the database. According to the characteristic parameters of different pump types, the corresponding comprehensive characteristic curves are drawn, and the comprehensive characteristi...

Abstract

The invention discloses an optimization design method of a water jet propeller based on a database, which relates to the field of amphibious vehicles and ships. A method for implement that invention comprises the follow steps of: establishing a database of a pump model; Input the design parameters into the pump model database, and optimize the design of the water-jet propulsion pump; the agent model and numerical simulation are combined to optimize the design of inlet passage. Design nozzle; According to the optimized inlet passage, the optimized water-jet propulsion pump and the designed nozzle, considering the matching relationship among them, the 3D solid modeling of the water-jet propulsion is carried out by using 3D drawing software. The optimized water-jet propulsion is applied to the amphibious vehicle and ship to improve the design efficiency, shorten the design cycle and solve the engineering problems in the corresponding field. The invention has the advantages of high designefficiency and short design period, and is favorable for practical application.

Description

technical field [0001] The invention relates to a database-based optimization design method for a water jet propeller, and relates to the fields of amphibious vehicles and ships. Background technique [0002] Waterjet propulsion is a device that uses the reaction force of jetting water to propel ships forward. With the development of related technologies, waterjet propulsion has been widely used in amphibious vehicles and high-speed boats and other fields. Compared with traditional propeller propulsion devices, water jet propulsion has many unique advantages. The water jet propeller does not need complex transmission devices, and can be directly driven by the main engine after deceleration; the water jet propeller is generally installed inside the hull, which is beneficial to the protection of the pump body in complex working environments; the water jet propeller can effectively reduce cavitation The generation of noise and vibration is reduced; the water jet propulsion has...
