Abstract
This paper presents a comprehensive finite element-based strength and stiffness optimization study of a solid aircraft engine propeller shaft subjected to combined bending and torsional loads. The analysis integrates both computational and material optimization techniques to improve structural efficiency while maintaining safety margins. Three candidate materialsAISI 4340 steel, Ti-6Al-4V titanium alloy, and carbon fiber reinforced polymer (CFRP)were analyzed under identical loading conditions using 3D solid models. The study evaluates stress distribution, total deformation, stiffness, and weight optimization using finite element simulations in ANSYS. The results show that while AISI 4340 exhibits the highest stiffness, CFRP offers the best strength-to-weight ratio and lowest overall mass. The findings provide valuable insights for designing lightweight yet durable propulsion components in modern aircraft systems.
