#CMT# #/CMT# The device has a rigid structure (8) and a front aerodynamic structure (24) that is mounted on the structure (8) via a mounting unit. The mounting unit comprises two connecting rods (32) placed in a symmetric manner with respect to a vertical median plane of the device, parallel to a longitudinal direction (X) of the device. A lower end of each rod is connected to an upper spar of the structure (8) and an upper end of each rod is connected in an articulated manner to a lower spar of the structure (24). The rods are designed such that their lengths are adjustable. #CMT#USE : #/CMT# Used for being interposed between an aircraft wing system and an engine of an engine e.g. turboshaft engine, assembly (claimed) that is fixed below a wing of an aircraft for suspending the engine below a wing of the aircraft or for mounting the engine above the wing of the aircraft, for constituting a connection interface between the engine and the wing of the aircraft, for transmitting efforts generated by the engine to a structure of the aircraft and for allowing to guide fuel, electric and hydraulic systems, and the air between the engine and the aircraft. #CMT#ADVANTAGE : #/CMT# The connecting rods are designed such that their lengths are adjustable, thus permitting to adjust the front aerodynamic structure with respect to the rigid structure in a simple and precise manner, while ensuring the mounting of the aerodynamic structure on the rigid structure. The rods can therefore be mounted in a differential manner such that one of the rods is active permanently and the other rod is active only in case of defect of the former rod. The latter rod can therefore ensure a fail safe function in normal conditions and does not ensure the passage of forces between the structures. The permanently active rod can therefore ensure taking up of forces exerted along a vertical direction of the device. The positioning of the aerodynamic structure permits to guarantee and control the position of fan fitting of a fan access door in a simple manner. The rods can be easily accessed by an operator situated at proximity of the device, thus facilitating placing operations and aerodynamic structure removal operations. The presence of the rods does not limit the accessibility at a space situated between the rigid and aerodynamic structures, where the space contains equipments to be accessed by the operator for placing or maintenance operations. Each rod is capable of taking up efforts in a single direction such that it forms an isostatic mounting system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a detailed partial view of an engine mounting device of an engine assembly.
