Engine desiccant racks, methods of installing the same, systems for preventing corrosion, and articulating contact structures

A desiccant rack for suspending one or more bags of a desiccant material within a housing of an aerospace structure, the desiccant rack comprising:

• a platform comprising:
• a first edge region and a second edge region opposite the first edge region, wherein the platform is configured to contact a first portion of a nonplanar wall of the housing at the first edge region and a second portion of the nonplanar wall of the housing at the second edge region, such that the platform is suspended by the nonplanar wall;
• a pair of rails and a plurality of rungs extending between the pair of rails, wherein each rail of the pair of rails is configured to extend from the first edge region of the platform to the second edge region of the platform, wherein the first edge region of the platform comprises a first rung of the plurality of rungs and wherein the second edge region of the platform comprises a second rung of the plurality of rungs;
• wherein the first edge region is defined by at least a first articulating contact structure coupled to the first rung by a first pivotable joint, and wherein the second edge region is defined by at least a second articulating contact structure coupled to the second rung by a second pivotable joint;
• and
• wherein the first articulating contact structure and the second articulating contact structure each comprise a body comprising a central hub and at least three legs extending from the central hub, wherein the body is coupled to a respective pivotable joint of the first and second pivotable joints at the central hub.
