What is the minimum required panel gap to compensate for the stresses of flexing in flight?

The minimum required panel gap that compensates for the stresses experienced during flexing in flight is essential in ensuring that aircraft structure remains intact and performs effectively under various conditions. A gap of 0.010 inches is established as a standard because it allows adequate space for expansion and contraction of materials due to temperature changes and the aerodynamic forces acting on the aircraft.

This consideration is critical in preventing any potential damage to the airframe caused by friction or binding of panels during movement or flexing. A smaller gap could lead to increased risk of wear and fatigue, while a larger gap may compromise the aerodynamic integrity of the aircraft by creating unnecessary drag. Therefore, maintaining a panel gap of 0.010 inches provides the necessary balance between performance and safety in aircraft structural design.
