This aeronautical equipment for an aircraft, comprising a part configured to be positioned at the level of a skin of the aircraft and means for reheating this part comprising a closed-circuit thermodynamic loop in which a phase-change heat transfer fluid circulates, is wherein it includes means for monitoring the fluid pressure in the loop in order to detect and report a malfunction of the equipment.

A thermal management system for a gas turbine engine and/or an aircraft is provided including a thermal transport bus having a heat exchange fluid flowing therethrough. The thermal management system also includes one or more heat source exchangers and a deicing module. The one or more heat source exchangers and the deicing module are each in thermal communication with the heat exchange fluid in the thermal transport bus. The one or more heat source exchangers are configured to transfer heat from one or more accessory systems to the heat exchange fluid, and the deicing module is located downstream of the one or more heat source exchangers for transferring heat from the thermal transfer fluid to a surface of one or more components of the gas turbine engine and/or the aircraft.

Embodiments, described herein relate generally to devices, systems, and methods for producing lubricious surfaces with enhanced durability and which increase the ease of communication of viscous liquids across the same. The system can include a liquid-encapsulated surface including a substrate, a member coupled to the substrate, and an encapsulating liquid disposed on a surface of the member. In some embodiments, the surface of the member can have a chemistry such that the encapsulating liquid preferentially wets the surface and maintains lubricity in the presence of a contacting phase. In some embodiments, the encapsulating liquid can be substantially immiscible with the contacting phase, and/or can have a thickness of less than about 200 microns and/or can have a receding contact angle of less than 20 degrees in the presence of the contacting phase, in some embodiments, a liquid delivery mechanism can be configured to transfer the encapsulating liquid to the member.
