Which term describes the smooth repair of a ragged edge on a blade?

The term that describes the smooth repair of a ragged edge on a blade is "blend." Blending involves carefully smoothing and reshaping the damaged area to restore the blade's aerodynamic properties and structural integrity. This process ensures that there are no abrupt transitions or rough surfaces, which could lead to performance issues or further damage during operation.

In aviation, maintaining the integrity of blades—such as those found on rotors or engines—is crucial for safety and efficiency. Proper blending not only improves the appearance of the blade but also minimizes drag and enhances overall performance.
