A spigot-type fastener for an aircraft is to be interposed between the structure of the aircraft and an attachment structure of the aircraft engine. The fastener is to absorb the force generated by the engine along two orthogonal axes. The fastener includes a first part, a second part, a third part, and one or more strain gauges. One end of the first part is secured to the second part. One end of the second part is separated from the first part by a clearance. The opposite end of the second part fits into a recess of the third part via a protrusion, such that the force along both axes is transmitted by the first part to the third part by the second part.

Spigot-type fastener provided with at least one means for measuring the force generated by an aircraft engine

A device for measuring a pattern of the forces and moments () generated by an aircraft propulsion system (), includes a hooking structure () that can support at least one propulsion system (). This hooking structure () passes through the fuselage transversely relative to the main axis of the fuselage of the aircraft via an opening, whereby the structure has at least a first part (AC) that is found on the outside of the aircraft connected to a propulsion system, and a second part (CB) that is found on the inside of the aircraft that is connected to structural elements of the aircraft via an isostatic system of connecting elements () so as to take up the six degrees of freedom, measuring elements being integrated in the connecting elements to reconstitute the pattern.

A sensor support includes a rigid insert, on which a sensor is installed, and a flexible envelope fitted at a bottom face thereof with a double-sided adhesive to bond the sensor support to an aircraft structure Assembly and disassembly of the sensor are easy and the air flow is only slightly disturbed. This device is applicable to flight test campaigns of an aircraft or simulated flights to measure noise or pressure.
