Production method of leading edge reinforcement of fan blade |
摘要 |
A production method uses ultrasonic forming but does not leave a bonding face exposed to the exterior in a final product. The production method of a leading edge member of a fan blade comprises the steps of causing superplastic forming by using a combination of a first mold having a flow path for gas and a second mold having a female mold to pressurize a plate member with the gas through the flow path to fit the plate member onto the female mold; bonding a backing with the plate member processed with the superplastic forming; and cutting out a periphery of the plate member to obtain a product shape. |

1. A production method of a leading edge member of a fan blade having a geometric shape, the method comprising:
causing superplastic forming by using a combination of a first mold having a flow path for gas and a second mold having a female mold to pressurize only a single unitary plate member with the gas through the flow path to fit the plate member onto the female mold; bonding a backing with the plate member processed with the superplastic forming; and cutting out a periphery of the plate member to obtain a product shape, wherein the bonding includes diffusion bonding by using a combination of a third mold having a male mold and a fourth mold having a flow path for gas to pressurize the plate member with the gas through the flow path of the fourth mold. |
