specific Embodiment approach 1

[0016] Specific implementation mode one: combine Figure 1-3 , this embodiment is a deformable propeller for ships based on two-way shape memory polymer composite blades, which is specifically composed of a hub 1 and a plurality of blades 2; the plurality of blades 2 are evenly arranged and fixed on a On the propeller hub 1; the propeller hub 1 is made of nickel, aluminum, bronze, titanium alloy material or resin matrix and fiber reinforced phase, wherein the mass fraction of the fiber reinforced phase is 30% ~70%; the paddle 2 is made of a material composed of two-way shape memory polymer and fiber reinforcement phase, wherein the mass fraction of fiber reinforcement phase is 30%-70%.

specific Embodiment approach 2

[0017] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the propeller hub 1 is made of nickel, aluminum, bronze, titanium alloy material or composite material of resin matrix and fiber reinforcement , where the fiber reinforcement is carbon fiber, glass fiber, Kevlar fiber or boron fiber. Others are the same as the first embodiment.

specific Embodiment approach 3

[0018] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the paddle 2 is made of a composite material of two-way shape memory polymer and fiber reinforcement, and the fiber reinforcement The phase is carbon fiber, glass fiber, Kevlar fiber or boron fiber. Others are the same as those in Embodiment 1 or 2.

Abstract

A marine deformable propeller based on a two-way shape memory polymer composite material blade relates to a marine deformable propeller. The content of the present invention is to solve the technical problem that the configuration of the current marine propeller is prepared before being installed on the ship, and the ship cannot be changed during the sailing process. A marine deformable propeller based on two-way shape memory polymer composite material blade of the present invention is composed of a hub and a plurality of blades; the plurality of blades are evenly arranged and fixedly installed on the hub along the circumferential direction; the described The blades are made from a composite of two-way shape memory polymers with fiber reinforcement. The paddle of the present invention can flexibly switch between pitching and non-pitching according to actual needs. The invention is applied to hull propellers.

Description

Technical field: [0001] The invention relates to a deformable propeller for ships. Background technique: [0002] The vibration and noise problems of marine propellers have been widely concerned by scientific researchers from various countries, and the vibration and noise problems of the interaction between the hull and propellers are more complicated and difficult to measure accurately, so propellers that change pitch have emerged as the times require. By changing the pitch of the propeller, the interaction between the propeller blade and the hull is weakened, but this method reduces the overall performance of the propeller, and the power provided by the propeller to the ship becomes smaller. The configuration of the current marine propellers is all prepared before being installed on the ship, and the ship cannot be changed during navigation. Contents of the invention [0003] The content of the present invention is to solve the technical problem that the configuration o...
