Assembly formed by a turbine engine and a system for attaching it to an aircraft structure

摘要

In an assembly including a bypass turbine engine and an attachment system attaching the turbine engine to an aircraft structure, the attachment system includes a mast, at least two rear attachments connecting the mast to two rear attachment points of the turbine engine, and a rear covering covering the rear attachments and providing a streamlined fairing. The rear covering includes two side walls, each including a first portion extending along and in proximity of the mast and extending rearwards, and a second portion projecting sideways relative to the first portion towards its outside, to cover the rear attachments. Each second portion is substantially a bulge and is connected to the first portion along a curved connection line extending between front and rear points situated substantially level with an inner longitudinal edge of the first portion to minimize the impact on a flow of bypass stream leaving the bypass passage.

主权项

1. An assembly comprising a turbine engine and an attachment system for attaching the turbine engine to an aircraft structure;
wherein the turbine engine is a bypass engine including an annular passage in which a core stream flows that opens out to a rear around a central body and an annular passage along which a bypass stream flows that opens out to a rear between a primary cover and a rear end of a secondary cover, and wherein the attachment system includes a mast, at least two rear attachments connecting the mast to two rear attachment points of the turbine engine, and a rear covering of the mast covering the rear attachments, providing a streamlined fairing and having a rear portion that extends rearwards beyond an opening of the core stream flow passage, a distance between the rear attachment points being substantially greater than a width of the mast level with the rear attachments; wherein the rear covering includes two side walls each including a first portion extending along and in proximity of the mast and extended rearwards, and a second portion that projects sideways relative to the first wall portion on an outside thereof to cover the rear attachments; and wherein the second portions of the side wall of the rear covering are substantially in a form of bulges and connect to the first portions of the side wall along curved connection lines extending between front points and rear points situated substantially level with inner longitudinal edges of the first side wall portions.
