This is a diagram from Niu showing shear reinforcement around a fuselage cutout.
In the shaded areas, a doubler is attached to the existing skin with a set of "field rivets". Does anyone have insight on the proper spacing for these rivets? I believe their main purpose is not to carry significant load but instead to ensure that the doubler and original skin behave as one thicker skin instead of two thinner ones.
Thanks,
David
