What is "compression" in the context of fabric covering?

In the context of fabric covering, compression refers to the application of tension to keep the fabric tight and smooth. This process is crucial because it ensures that the fabric adheres securely to the aircraft structure, preventing wrinkles and sagging that could impair performance and aesthetics. Proper tensioning helps maintain the integrity of the covering, allowing it to effectively withstand the stresses of flight, including changes in temperature, airflow, and pressure.

When fabric is tightly stretched, it provides a smooth surface that minimizes drag and enhances the aerodynamic qualities of the aircraft. This technique is essential during the fabric covering process, as it contributes to the overall durability and safety of the aircraft. By ensuring that the fabric is properly tensioned, you also facilitate better bonding with the underlying structure and coatings, leading to a more resilient covering that can endure various environmental conditions.

Other choices, while related to the fabric covering process, do not accurately capture the specific definition of "compression." Application of heat or color and the layering of materials serve different purposes in the overall covering process and do not directly pertain to the concept of maintaining fabric tightness and smoothness through tension.
