Research progress in manufacturing technology of aviation composite propeller blade

Propeller propulsion technology plays an important role in aviation field. Composite materials have the characteristics of high specific strength, high specific modulus, high damping, designability and so on. The use of composite material propeller blades can further improve the performance of propeller in terms of mass reduction efficiency, propulsion efficiency, corrosion resistance, noise reduction. Composite material propeller blades have become the general trend. Based on aircraft propeller blades and rotor blades, this paper aims to perform a brief review of the research achievements of aviation composite propeller blades at home and abroad, classifies and expounds the material systems, structural design and molding processes of aviation propellers. The key technical problems and the simulation research on manufacturing process of propeller at home and abroad are summarized. Finally, the future development direction of domestic composite propellers from the aspects of improving the material system, opti
