Propeller is a device used to propel spacecraft such as aircraft or rockets forward, in which the spindle is an important part of propeller. According to different use requirements and technical requirements, the material of the spindle can be selected in many ways. Commonly used materials are stainless steel, titanium alloy, aluminum alloy and so on. These materials have the characteristics of high strength, corrosion resistance and fatigue resistance, and are suitable for use in extreme environments. At the same time, different spindle materials will also have an impact on the performance and cost of the propeller, which needs to be selected after comprehensive consideration of various factors.
Propeller, as one of the core equipment of spacecraft, plays a vital role in ensuring the normal operation of spacecraft and achieving mission objectives. With the continuous development and innovation of science and technology, the design and manufacture of propellers are constantly improving and perfecting. In the future, there will be more choices and new research results of propeller spindle materials, which will make greater contributions to the aerospace industry.
