Compressor blade loading refers to the stress experienced by compressor blades due to centrifugal forces, which is most significant near the hub. This stress can lead to tensile and radial forces that challenge the blade's structural integrity. The design often includes a curved root to enhance strength in these high-stress areas. Additionally, aerodynamic factors contribute to varying tangential velocities across the blade, affecting loading. Understanding these dynamics is crucial for optimizing blade design and material selection, especially with advancements in anisotropic metal alloys.
