Abstract: The present invention relates to an aircraft (1) provided with at least one rotary element (10) provided with blades (11) liable to come into contact with a liquid surface (100) on ditching, said aircraft including a buoyancy system. The aircraft includes a fairing (15) surrounding at least part of said rotary element (10), the fairing (15) including an inflatable emergency float (20) of the buoyancy system for preventing said blades (11) from coming into contact with the liquid surface when in an inflated position.

Abstract: Tooling is organized firstly to implant an insert (1) in a cellular panel (2) by means of a thermally reactive sealing material (3), and secondly to withdraw the insert from said cellular panel (2). The tooling comprises an instrument (9) provided a heater endpiece (10) that is in relationship with heater means (11) and that is arranged as a finger suitable for being received inside a cavity (6) in the insert (1) in order to raise the temperature of the sealing material (3). The instrument (9) is fitted with grip means (12) for gripping the insert (1), which grip means are arranged on the heater endpiece (10), and with relative positioning means (13) for positioning the instrument (9) relative to the cellular panel (2).

Abstract: An aerially transportable tank (20) for storing a composition for discharging in flight, the tank including a neck (23) terminated by a composition discharge opening (24), and having a wall (21) extending the neck that is sufficiently deformable to be received in part or in full within the neck.
