The invention belongs to the technical field of propellers, and discloses a propeller model and a cavitation test method. The propeller model comprises a hub and a plurality of blades, the blades are arranged at intervals in the circumferential direction of the hub, the blades and the hub are integrally formed, and the blades have at least two different design parameters. According to the propeller model and the cavitation test method provided by the invention, different blade design parameters can be applied to different blades of the same propeller, so that a plurality of different design parameters can be verified through one cavitation test, even if one scheme does not reach a design index, other design parameters can still be adopted, and the design efficiency is improved. The propeller blade redesign, the model reprocessing and the cavitation test do not need to be carried out again, so that the propeller design process and the cavitation test process are more efficient.

    本发明属于螺旋桨技术领域,公开了一种螺旋桨模型及空泡试验方法。该螺旋桨模型,包括轮毂和多个桨叶,多个所述桨叶沿所述轮毂周向间隔设置,多个所述桨叶与轮毂一体成型,且多个所述桨叶中至少有两种不同的设计参数。本发明提供的螺旋桨模型及空泡试验方法能够将不同的桨叶设计参数应用于同一个螺旋桨的不同桨叶中,使得通过一次空泡试验即可对多个不同设计参数进行验证,即便有一个方案没有达到设计指标,仍然可以采用别的设计参数,而无需重新设计桨叶、重新加工模型、重新空泡试验,使螺旋桨设计过程和空泡试验过程更加高效。
