Arrangement for mounting a propulsive system on an aircraft airframe (12) by means of an external strut (4) which connects the engine (1) with the airframe (12), said strut (4) comprising a plurality of spars (8) intruding into the airframe (12) and means (7, 9, 11) for attaching said spars (8) to the internal airframe structure (10), the cited means (7, 9, 11) being dampers, shock absorbers or active actuators with characteristics chosen so that the said means (7, 9, 11) are particularly suited for the efficient reduction of attachment and internal dynamic loads arising mainly but not only from hard landing events and aircraft flight manoeuvres, and for damping sustained vibrations of the propulsive system-airframe (12) assembly, the said arrangement allowing the easy removal of the strut (4) from the rest of the said airframe (12) and the interchangeability of the said strut (4) between different aircrafts, being also the cited arrangement tolerant to damage or complete failure of at least one of the said spars (8).
