Definitions
- the present invention relates to a guide assembly for a mobile unit nacelle unit for turbojet, and also relates to a thrust reverser equipped with such a guide assembly. Finally, the invention also relates to a turbojet engine nacelle equipped with such a thrust reverser.
- An aircraft is driven by several turbojets each housed in a nacelle also housing a set of ancillary actuators related to its operation and providing various functions when the turbojet engine is in operation or stopped.
- These ancillary actuating devices comprise in particular a mechanical system for actuating thrust reversers.
- a nacelle generally has a tubular structure comprising an air inlet upstream of the turbojet engine, a median section intended to surround a fan of the turbojet engine, a downstream section incorporating a thrust reverser means and intended to surround the combustion chamber of the turbojet engine. , and is generally terminated by an ejection nozzle whose output is located downstream of the turbojet engine.
- the modern nacelles are intended to house a turbofan engine capable of generating through the blades of the rotating fan a flow of hot air (primary flow) and a cold air flow (secondary flow) flowing to the outside of the turbojet engine through an annular passage, also called a vein, formed between a fairing of the turbojet and an inner wall of the nacelle.
- the two air flows are ejected from the turbojet engine from the rear of the nacelle.
- the role of a thrust reverser is, during the landing of an aircraft, to improve the braking capacity thereof by redirecting forward at least a portion of the thrust generated by the turbojet engine.
- the inverter obstructs at least a portion of the flow of the cold flow and directs this flow to the front of the nacelle, thereby generating a counter-thrust which is added to the braking of the wheels of the plane.
- a common thrust reverser structure comprises a cowling in which an opening is provided for the deflected flow which, in a situation of direct thrust of the gases, is closed by a sliding cowling and which, in a reverse thrust situation, is disengaged. by translational movement downstream (with reference to the flow direction of the gases) of the sliding cowl, by means of displacement cylinders of the sliding cowl, said displacement cylinders being mounted on a cowling frame upstream of the 'opening.
- the sliding cowl is most often formed of two semi-cowls, of substantially semicylindrical shape, which are hinged at the upper part (at 12 hours) on hinges parallel to the direction of translation of the sliding cowl, and which are closed. by locks in the lower part (at 6 o'clock).
- This arrangement allows, for maintenance operations, access to the interior of the nacelle, including the turbojet engine or an internal structure of the inverter opening these half-covers.
- Another possible thrust reversal structure comprises an outer assembly in a single part without breaking in the lower part. Such a structure is called structure in O.
- the external structure is dissociated from the internal structure surrounding the engine and is translated downstream, beyond a reverse thrust reversal value in which it simply releases the inversion grids. , so as to allow access to the motor body.
- deflection grids always limit accessibility to the heart of the nacelle. It is therefore necessary to retract them if one wishes to be able to give free access to the heart of the basket.
- a solution is also known to slide downstream of the nacelle the deflection grids and the frame before supporting them, in order to access the engine zone to perform maintenance operations of the nacelle and the turbojet engine.
- This solution consists of a unitary assembly consisting of the front frame and the deflection grids, detachable from the fan case to which it is attached, and translatable to the downstream of the nacelle via a slider adapted to move along a slideway secured to the pylon supporting the nacelle.
- the section of the slides is generally substantially semi-cylindrical so as to allow a slight angular displacement of the slide in case of deformation between the fixed structure to which the moving assembly is connected.
- the front frame In the active position, that is to say when the front frame is connected to the fan casing, the front frame undergoes aerodynamic forces tending to open the unitary assembly constituted by the front frame and the deflection grids downstream. of the nacelle.
- the forces experienced are typically circumferential compressive forces, resulting in a rotation of the integral slide of the unitary assembly about the longitudinal axis of the slideway, as illustrated in FIG. 1 schematically showing the slide 19 which has been pivoted a few degrees from each other. at its rest position, in the slideway 17 under the aerodynamic forces experienced by the unitary assembly.
- This rotation has the effect of causing almost instantaneous contact between the slider and the slider at the level of zone A, resulting in a poor transmission of circumferential forces to the mast supporting the turbojet engine nacelle.
- the present invention aims at solving the above-mentioned drawbacks of the prior art, and relates for this purpose to an assembly comprising at least one unitary nacelle unit for a turbojet, mobile with respect to a fixed structure along at least one assembly associated guiding system, said guide assembly comprising:
- said assembly being remarkable in that the guided element and the guiding element each have at least one non-complementary profile to each other at least at said contact surface, said profiles being shaped to achieve at least a support-plane connection at least during circumferential forces of said unitary assembly.
- the guided element and the guiding element each have at least one non-complementary profile to each other at least at the level of said contact surface, which means that the section of the element gu idant at the level of the surface of contact with the gu ide element is geometrically substantially distinct from that of the guiding element.
