A circuit includes an evaporator receiving heat from a hot body; a condenser transmits heat to a cold body, a working fluid flows through a first conduit in vapour phase from the evaporator to the condenser, and flows through a second conduit in liquid phase, from the condenser to the evaporator. A first evaporator portion is in fluid communication with the second conduit and acts as a compensation chamber. A second evaporator portion is in fluid communication with the first conduit and contains the vapour phase. A porous wick moves the working fluid from the first evaporator portion to the second evaporator portion. A first flow controller interrupts or allows flow when fluid temperature in the elevator is respectively lower or higher than a first threshold. A second flow controller interrupts or allows flow when the temperature in the condenser is respectively higher or lower than a second threshold.

A tool for forming a C-section beam made of carbon fibre includes a straight elongated mandrel with a rectangular or trapezoidal cross-section. The mandrel has three consecutive outer faces, with a planar face configured to form a surface of the web of the C-section beam, and two opposing lateral faces, configured to form two respective surfaces of the flanges of the C-section beam. The mandrel has a distributed perforation on at least one of the three outer faces and an inlet/outlet connection to connect the mandrel to an external source of vacuum and/or compressed air. Passages are formed inside the mandrel to establish a fluid communication between the distributed perforation and the inlet/outlet connection. Through the distributed perforation, a vacuum is applied to the interface between the mandrel and the C-section beam to retain the C-section beam on the mandrel while lifted and turned by 180 for coupling to a similar C-section beam to assemble an H-beam. Applying compressed air through the perforation facilitates the removal of the C-section beam from the mandrel at the end of the compaction step.

A system for preventing icing on an aircraft surface includes a plasma actuator which is applied onto an aircraft surface operationally exposed to air and which is arranged for generating at least one plasma discharge (D) for inducing a flow (F) of ionized hot-air particles towards the surface.

A method for producing a closed-section portion of an aircraft wherein a strain gauge is glued on a first face of a flat tape that, in turn, is fastened on a face of a tool comprising a rigid elongated body covered by an extensible sack. The tool supporting the tape is arranged in a cavity of an aircraft structure. A vacuum is then created to obtain the expansion of the vacuum sack and perform the pressure gluing of the tape onto a wall of said cavity. The tool is subsequently extracted from the cavity. Upon conclusion of these operations, the tape is integrally fastened onto a wall of the cavity so that any deformation applied to this wall is transmitted to said strain gauge.

A method determines the tack of a material placed in contact with a surface. A sample is provided of the material, the sample including a sheet whose width increases from a first narrow end to a second wide end. The sample is applied to an upwards facing supporting surface of plate. The sample is compacted against the supporting surface of plate and a weight is attached to the first end of the sample. The plate is turned over in such a way that the supporting surface faces downwards. The detachment of the sample from the supporting surface is measured in terms of distance detached from the first end of the sample as a function of time.
