Embodiment Construction

[0033] figure 1 Shown is a power plant for an aircraft comprising a nacelle constituting a tubular casing for a bypass jet engine 1 and for guiding the hot and cold airflows generated by the bypass jet engine 1 .

[0034] The nacelle has a structure comprising a front part 4 forming the air intake, a middle part enclosing the fan 9 of the jet engine 1, and a rear part enclosing the jet engine 1 and equipped with two movable thrust reverse cowls 3, the middle Part is used as fan housing 7.

[0035] A movable cowl 3 having a generally semi-cylindrical overall shape is articulated about an axis 6 substantially parallel to the longitudinal axis A of the nacelle so that the movable cowl 3 can be opened to access the jet engine 1 for maintenance operations and comprises a lower edge with an opening handle 10 .

[0036] The jet engine 1 is suspended to the wing 5 of the aircraft by means of a pylon or strut 2 mounted to the jet engine 1 at its front.

[0037] In this configuration...

Abstract

The present invention discloses a nacelle that has movable cowls (3) articulated to an longitudinal axis of the nacelle to open the cowls for providing access to a two-flow turbojet (1), and paired by an attachment unit (8) which permits articulation of the cowls one on another around a discrete or merged hinge line (6). Each cowl has a permanent connection unit constituted of a hanger and a support rod or a temporary link unit to provide temporary link when the cowl is close in rotation with a fan casing (7) of the nacelle. The link unit has a recess cut out (15) to receive a stop (14) arranged in a peripheral groove (13).

Description

technical field [0001] The invention relates to jet engine nacelles. Background technique [0002] The aircraft is propelled by several jet engines, each of which is housed in a nacelle that also houses an associated set of actuating devices (such as thrust reversers) to achieve various functions. [0003] The nacelle generally has a tubular structure comprising an air intake upstream of the jet engine, a central portion arranged to enclose the fan of the jet engine, and a downstream portion housing the thrust reverser and designed to enclose the combustion chamber of the jet engine, the nacelle Usually ends in an exhaust nozzle, the outlet of which is located downstream of the jet engine. [0004] A modern nacelle is designed to house a bypass jet engine, which is able to generate a hot airflow (also called main airflow) from the jet engine's combustion chamber through the rotating blades of the fan and around the jet engine through an annular passage (also called duct) ...
