A link including a rod with a connection member at each end with an axis passing through both connection members. The rod includes a fusible zone as a narrow section lying between a first rod portion connected to a first connection member and a second rod portion connected to a second connection member. The fusible zone breaks when tensile force to which the link is subjected is greater than a predetermined value. The two rod portions are inseparable in event of the fusible zone breaking by a cylinder coaxial about the axis and secured to the first rod portion, and having an end wall through which the second rod portion passes. The second rod portion includes a collar that can slide into the cylinder if the fusible zone breaks. The inside wall of the cylinder includes teeth configured to be broken by the collar if the fusible zone breaks.

Fusible link comprising damper and backstop

A process for the early detection of a possible fault in a rotary component of an engine wherein a signal representing an acceleration is stored in a sequential manner; the stored signal is transformed into a frequency signal a spectral coherence calculation is performed between said frequency signal and the same frequency signal shifted by frequency values predetermined as a function of the speed of the engine; the sequences are counted for which a correlation peak appears for one of the predetermined frequencies and a fault is deemed to be present if for a number P of consecutive sequences the number of sequences with a correlation peak is greater than a predetermined threshold.

Process for the detection of damage to components of an engine

The drive system of a propeller driven transport aircraft has first and second propeller doublets mounted in the plane of the aircraft wings, each propeller doublet including two propellers disposed symmetrically on opposite sides of the central longitudinal axis of the aircraft. The first and second propeller doublets are driven independently of one another by first and second engine units via first and second independent drive trains respectively, the first and second engine units being disposed side by side in the aircraft fuselage.
