Embodiment Construction

[0025] figure 1 Two turbojet engines 10 mounted on the tail of the fuselage 1 of the aircraft are shown. figure 2 shows the view from the left figure 1 In the case of the right turbojet 10 , the left and right should be understood as the two sides used with reference to the direction of air flow in the turbojet, as defined earlier in this application. The expressions upstream and downstream should also be used with reference to this airflow.

[0026] The turbojet engine 10 comprises a fan 11 surrounded by a front casing 12 , which is itself protected by fan casings 13 , 13 ′. On the downstream side of the fan 11 , the turbojet comprises in sequence a compressor 14 , a combustion chamber 15 , a turbine 16 and a nozzle 17 . On the downstream side of the turbine 16 is a rear housing 18 held in place by a support arm.

[0027] More precisely, the front housing 12 is divided into a holding housing which surrounds the fan 11 and an intermediate housing which surrounds the defle...

Abstract

The turbojet engine according to the invention is designed to be mounted above the tail of the aircraft fuselage (1) by at least one suspension ((28, 128), (28', 128')), the turbojet engine (10) It includes a fan (11), a front casing (12), a rear casing (18) and accessories (22, 23, 24, 25) arranged around the front casing (12), and the front casing (12) includes Connection points ((31, 32, 33), (31', 32', 33')) for connecting suspensions (28, 28'). These connection points are arranged so that the turbojet engine (10) can be installed on each side of the aircraft fuselage (1) indiscriminately, and the arrangement of the accessories (22, 23, 24, 25) on the casing is such that regardless of On which side the turbojet is mounted, it can be reached from the outside of the aircraft fuselage (1).

Description

technical field [0001] The invention relates to a turbojet engine for an aircraft. Background technique [0002] Aircraft manufacturers are very concerned about the noise problem, which can disturb the residents living near the airport. Aircraft manufacturers want to minimize the noise generated, which mainly starts with the fan and nozzle of the turbojet engine. [0003] Document US6199795 proposes a turbojet engine assembly installed near the tail of the aircraft and above the fuselage; part of the fan noise is reflected by the fuselage, while part of the nozzle noise is reflected by the vertical or horizontal stabilizer of the empennage. In addition, the front part of the fuselage acts as a shield on the inlet side of the turbojet engine against the entry of objects that could damage the turbojet engine. Also, the wing no longer supports the turbojet engine, thereby reducing the load on it, which also has a number of aerodynamic benefits. [0004] But a turbojet engine...
