Abstract
Pliable-wall air ducts with internal expanding structures are disclosed. An example air duct system includes an air duct including a pliable sidewall. The example air duct system further includes a shaft including a first end and a second end. The shaft extends in a longitudinal direction along a length of the air duct with the first end coupled to a first point of the air duct and the second end coupled to a second point of the air duct. The first point is downstream of the second point. The pliable sidewall is to be held in tension in the longitudinal direction between the first and second points in response to compression in the shaft between the first and second ends.
