Duct support

A rotorcraft comprising:

• an airframe configured to support one or more components of the rotorcraft, the one or more components comprising:
• an aircraft system comprising at least one heat generating element;
• a duct configured to vent heat from the heat generating element to the environment;
• a stabilizing mechanism configured to transfer a weight of the duct to the airframe of the rotorcraft, wherein the duct of the rotorcraft undergoes thermal expansion, wherein the stabilizing mechanism includes:
• a first stabilizing member attached to the duct of the rotorcraft;
• a second stabilizing member attached to the rotorcraft, wherein a portion of the second stabilizing member extends above the airframe of the rotorcraft;
• and
• a coupling mechanism located in the portion of the second stabilizing member that extends above the airframe of the rotorcraft, the coupling mechanism including a barrel with a hollow inside portion and a rod that extends through the inside portion of the barrel along a first axis, wherein a portion of the first stabilizing member extends past the coupling mechanism, wherein the coupling mechanism is configured to rotatably couple the first stabilizing member to the second stabilizing member and allow the first stabilizing member to simultaneously slide back and forth and to rotate relative to the second stabilizing member about the first axis.
