Abstract: A test system for equipment using fuel, including a closed supply circuit of the equipment configured to supply contaminated fuel to the equipment is provided. The circuit includes at least one tank including fuel, and a pollution module including on or more vats including fuel contaminated by solid contaminants. The module is configured to introduce contaminated fuel to a section of the supply circuit in which the fuel extracted from the tank circulates towards the equipment. The module also includes an agitating tool configured to take contaminated fuel from the vat and return it to the vat, so as to agitate the contaminated fuel in the vat.

Abstract: The invention relates to a test system (1) for equipment using fuel, characterised in that it comprises a closed supply circuit (2) of the equipment configured to supply contaminated fuel to the equipment (3), said circuit comprising: at least one tank (4) comprising fuel, and a pollution module (5), comprising one or more vats (6), comprising fuel contaminated by solid contaminants, said module (5) being configured to introduce contaminated fuel to a section (8) of the supply circuit (2) in which the fuel extracted from the tank (4) circulates towards the equipment (3), and an agitating tool (13), configured to take contaminated fuel from the vat (6) and return it to the vat (6), so as to agitate the contaminated fuel in the vat (6).

Abstract: A fan or compressor stage rotor comprises a disc, radial blades mounted in axial sockets formed in the periphery of the disc, and spacer blocks interposed between the blades to constitute the inner boundary of the air flow path through the rotor. The spacer blocks each comprise an outer wall which is spaced from the periphery of the disc, and front and rear walls extending radially inwardly to overlap at least partially the front and rear faces of the disc. The front and rear walls each comprise at least one hook which co-operates with a corresponding groove provided in the respective face of the disc to fix the spacer block to the disc. The spacer block also comprises a median partition projecting inwards from its outer wall and having a slot through which passes a leaf spring of a vibration damper.
