The invention relates to a method for mounting an engine module (1) in a support comprising a first structure (3) and a second structure (2) that is offset relative to the first structure (3), method intended for positioning at least a specified part (4) of the engine module (1) relative to an eleme
The invention relates to a method for mounting an engine module (1) in a support comprising a first structure (3) and a second structure (2) that is offset relative to the first structure (3), method intended for positioning at least a specified part (4) of the engine module (1) relative to an element (6) of the second structure (2) by means of an isostatic suspension connecting the engine module (1) to said first structure (3) by means of first connecting rods (10a, 10b, 10c, 10d) and to said second structure (2) by means of second connecting rods (10e, 10f), the length of said first and second connecting rods being defined in advance, method wherein the length of at least two (10c, 10f) of said first and second connecting rods is adjusted relative to the previously defined length thereof, in order to position said specified part (4) of the engine module (1) relative to said element (6) of the second structure (2) in said support. The invention also relates to said support comprising adjustable connecting rods, in an installation comprising in particular an auxiliary power unit for an aircraft.

1. Method for mounting an engine module in a support comprising a first structure and a second structure that is offset relative to the first structure, the method comprises: positioning the engine module relative to the second structure by means of an isostatic suspension connecting the engine module to said first structure with first connecting rods, and to said second structure with second connecting rods, the length of said first and second connecting rods being defined in advance, andadjusting the length of at least two of said first and second connecting rods relative to the previously defined length thereof, in order to position a specified part of the engine module relative to an element of the second structure in said support. 2. Method according to claim 1, wherein the length of all the first connecting rods is adapted relative to a variation in alignment of the second structure relative to the first structure, the length of all the first connecting rods being adapted relative to their previously defined length. 3. Method according to claim 1, wherein the adjustment of the lengths of said connecting rods comprises a step in which a model of the engine module, reproducing, with the same geometry, attachment points for the suspension connecting rod device and a zone representing the specified part of the engine module configured to be positioned relative to the second structure, is fixed to the support, the means for fixing the model using the first and second connecting rods, the previously defined length of which is maintained, and a step of detaching the model from the support. 4. Method according to claim 3, wherein the means for fixing the model to the support comprise at least one connection between the zone representing said specified part of the engine module to be positioned and the corresponding element of the second structure. 5. Support comprising a first structure, a second structure that is offset relative to the first structure, configured to hold an engine module by means of an isostatic suspension connecting said engine module to said first structure with first connecting rods and to said second structure with second connecting rods, said isostatic suspension being arranged so that at least a specified part of the engine module is positioned relative to an element of the second structure, at least two of said first and second connecting rods comprising a means for adjusting the length thereof. 6. Support according to claim 5, wherein all the first connecting rods comprise a means for adjusting the length thereof. 7. Support according to claim 5, wherein at least two of said first and second connecting rods are configured so as to be connected to the same attachment point on the engine module. 8. Support according to claim 5, wherein the means for adjusting the length of at least one of said first and second connecting rods comprises a tube and a rod cooperating by a means for screwing the rod into the tube. 9. Assembly comprising a support according to claim 5, and an engine module held by said isostatic suspension, said specified part of the engine module being placed so as to match said element of the second structure. 10. Assembly according to claim 9, wherein the second structure is offset relative to the first structure and the engine module is offset relative to the first structure in the same offset direction as the second structure, points of attachment of said first connecting rods to the module being located in the vicinity of the end of the module facing the first structure. 11. Assembly according to claim 9, wherein at least two of said first and second connecting rods are configured so as to be connected to the same attachment point on the engine module, and said two connecting rods configured so as to be attached to the same attachment point on the engine module are connected to the same first bracket comprising one of the parts, male or female, of a conical bolt, the complementary part of which is located on a second bracket fixed to the engine module, the conical bolt having an axis determined by the shape of the second bracket, assembly wherein the axis of the conical bolt is substantially tangential to a path followed by the first bracket when said bracket is moved away from the second bracket. 12. Assembly according to claim 9, wherein the engine module comprises an APU having a nozzle outlet, the second structure comprising an exhaust means having a mouth, the outlet end of said nozzle of the engine module being positioned so that the mouth of the exhaust means surrounds a portion thereof without touching it. 13. Support comprising a first structure, a second structure that is offset relative to the first structure, configured to hold a model of an engine module by means of an isostatic suspension connecting said model to said first structure with first connecting rods and to said second structure with second connecting rods, said isostatic suspension being arranged so that a zone of the model is positioned relative to an element of the second structure, at least two of said first and second connecting rods comprising a means for adjusting the length thereof. 14. Assembly comprising a support according to claim 13, and a model of an engine module held by said isostatic suspension, the zone of the model being placed so as to match said element of the second structure. 15. Assembly according to claim 14, wherein the model comprises a zone representing a nozzle outlet of an APU, the second structure comprising an exhaust means having a mouth, the outlet end of said zone representing a nozzle outlet of an APU being positioned so that the mouth of the exhaust means surrounds a portion thereof without touching it. 16. Model in an assembly according to claim 15, said model being provided with a means able to hold the zone, representing the nozzle outlet, in the mouth of said exhaust means according to two degrees of freedom.
