Abstract: A heat exchanger module including: a hollow chamber having an inner volume configured through which flows a first fluid in fluidic communication with a source of the first fluid, and a fluid outlet; a hollow enclosure extending outwardly from a surface of the hollow chamber wherein the hollow enclosure includes an inner volume through which flows a second fluid that undergoes a phase change in an operative mode of the heat exchanger module, wherein the hollow enclosure is in fluidic communication with a source of the second fluid, and an enclosure root of the hollow enclosure is inserted in the hollow chamber extending into the inner volume such that in an operative mode a second fluid flowing through the hollow chamber from the inlet to the outlet bathes the outer surface of said enclosure root.

Abstract: A composite multi-spar aircraft lifting surface comprising an integrated torsion box having a first portion of a skin continuous on the second face from a right tip to a left tip, a second portion of a skin continuous on the lateral right side of the first face from a right tip to a first central portion, a third portion of a skin continuous on the lateral left side of the first face from the left tip to a second central portion, a cover spanning between the first central portion and the second central portion. The spars, the first portion of the skin, the second portion of the skin and the third portion of the skin being an integrated multi-cell part. Also a method of manufacturing such a lifting surface.

Abstract: An aircraft empennage, comprising a rear fuselage section, a trimmable horizontal tail plane comprising a first and a second lateral torsion box), each comprising a front spar and a rear spar, a front fitting and a rear fitting, an actuator acting on the front fitting for a rotation of the trimmable horizontal tail plane around a hinge axis passing through the rear fitting, the front fitting comprising a first and a second front fitting units being joined to the front spars of the lateral torsion boxes, and the actuator comprising first and a second actuator units, each acting on the first front fitting unit and the second front fitting unit respectively.
