Systems and methods for inspecting airship structures

An airship structure, comprising:

• one or more first joints, wherein each of the first joints comprises a plurality of first slots having an open internal interface therebetween such that the plurality of first slots are volumetrically connected internally;
• a plurality of second joints, wherein each of the second joints comprises a plurality of second slots having a closed internal interface therebetween such that the plurality of second slots are volumetrically isolated internally;
• and
• a plurality of tubes with hollow centers connecting the one or more first joints and the plurality of second joints to form a continuous internal volume within the airship structure, wherein each end of the tubes is inserted into either (a) one of the plurality of first slots of one of the one or more first joints or (b) one of the plurality of second slots of one of the plurality of second joints;
• wherein at least one slot selected from the first slots or the second slots has a hole configured to receive air injected into the continuous internal volume to inspect the airship structure.
