What is the diameter of the propeller of the aircraft carrier? Materials and methods for manufacturing propellers?

A, the diameter of the aircraft carrier propeller

This is the world's largest Ford-class aircraft carrier before launching.

Reference nimitz CVN

The propeller of the 77 Bush aircraft carrier is 6.4 meters in diameter. An aircraft carrier has four propellers, each propeller has five blades, and each blade weighs 30 tons.

Ford class should be bigger!

A-class aircraft carrier has two anchors, each weighing 30t. Weight of anchor chain per lap163.3kg. Four five-blade propellers, 6.40 meters in diameter, each weighing 30,028.32 kilograms. * * There are two rudders, each weighing 65.5 tons.

The diameter of shaft hole has not been seen or introduced so far, because it is a manufacturing parameter.

Second, materials.

The invention relates to a method for manufacturing a carbon fiber composite propeller by secondary molding, which comprises the following steps: firstly, selecting a processing die and a material.

Reinforcing materials and resins are coated, hot-pressed, cooled, coated and wound to manufacture carbon fiber prepreg. The metal hub is made by machining, and the carbon fiber prepreg is coated on the metal hub after shot peening.

Put the composite hub as an insert in the center of the propeller metal mold, then lay the reinforced propellers one by one, lay twelve layers, close the mold after laying, inject glue, cure and post-treat.

The propel of that invention is made of carbon fiber composite material, which has high specific strength, large specific modulus, fatigue resistance, low vibration, low noise, light weight, high efficiency, corrosion resistance, easy maintenance and long service life; Firstly, the hub is formed for the first time, and then the propeller is formed for the second time. The process is simple and mature, and the carbon fiber composite propeller can be produced independently.
