What is the function of a "degree of tautness" during the covering process?

The function of a "degree of tautness" in the fabric covering process is crucial for ensuring the fabric is stretched properly. Achieving the correct tautness is essential for maintaining uniform pressure across the surface of the fabric. This ensures that the fabric lays flat against the aircraft's structure, which minimizes any movement during operation. If the fabric is too loose, it can flutter or become damaged as the aircraft is in motion, which can compromise the integrity and safety of the covering. Proper tautness also helps in maintaining aerodynamic properties and prevents any stress concentrations that could lead to wear or tear over time.

While other factors like aesthetic appeal and future repair considerations are important, the primary function of tautness is to provide a secure and stable covering that performs well in the dynamic environment of flight. Moreover, while varying fabric thickness may be a consideration in certain applications, the tautness itself does not inherently allow for thicker edges.
