Aerodynamic shape optimization design of propellers based on propeller blade strip theory (vortex theory), CFD numerical computation and multi-island genetic algorithm

ANSYSR was used to analyze the centrifugal force, gravity and aerodynamic force of the blade, calculate the strength, and design the propeller layup.

Rotating machinery is prone to resonance, so the natural frequency of the blade is calculated to ensure that the blade will not undergo resonance damage under the action of rotational excitation force.
