Abstract
A cellular structure includes a base, a plurality of hollow cells coupled to the base, a sealing layer, and a pressurization system. The base includes at least a first layer and a second layer. The cells each extend outwardly from the base, and are grouped together in at least a first zone, a second zone, and a third zone. The cells in each of the first, second, and third zones are only coupled in flow communication with the cells in that respective zone. The pressurization system is coupled to the first, second, and third zones for selectively and independently pressurizing each of the zones. The pressurization zone is configured such that in a first mode of operation, the first zone is pressurized and the second and third zones are depressurized, and in a second mode of operation, the first zone is depressurized while the second and third zones are pressurized.
