Lateral turbojet improved in order to limit the deformation thereof

摘要

A turbojet includes an intermediate casing outer shroud connected to a front suspension and a primary structure connected to a rear suspension; the shroud and the primary structure are held in a coaxial relationship by arms with at least some of the arms being shaped and/or arranged to deform in response to thrust from the turbojet by creating a deforming torque between the shroud and the primary structure in opposition to opposing stress generated by the thrust.

1. A two-stream turbojet for attaching laterally to a fuselage of an airplane via two longitudinally spaced apart suspensions including a front suspension and a rear suspension, the turbojet comprising:
an intermediate casing outer shroud attached to the front suspension; and a propulsion primary structure attached to the rear suspension; the intermediate casing outer shroud and the propulsion primary structure being held in a coaxial relationship by a set of arms, each arm including a right section that is hollow and being fastened by ends thereof to the intermediate casing outer shroud and to the propulsion primary structure; and wherein at least some of the arms include a C-shaped right section defined by a slot extending from the intermediate casing outer shroud to the propulsion primary structure, wherein in response to thrust from the turbojet, the C-shaped right section creates a deforming torque between the intermediate casing outer shroud and the propulsion primary structure, the deforming torque having a direction opposite to a bending moment that is generated under effect of the turbojet thrust by a force reaction couple at a thrust axis and the front suspension.
