Abstract
The structure design and manufacturing of the fan blade ware researched based on large-scale temperature change, high-revolution, multi-constraint conditions, high-fidelity profile and so on. The numerical modeling was performed in MSC, including strength, stiffness as well as eigenfrequency analysis, optimized to layer thickness and mass of blade. The resin transfer molding (RTM) process was used to ensure the blade geometrical tolerance. Multiform tests were provided to verify that the design and manufacturing is reasonable and the blade satisfies with application requirement.
