Abstract
A nacelle, a part of which is the fairing device, surrounds a gas turbine engine (4) and a support pylon (7) on an aircraft fuselage (15). The pylon extends into a substantially horizontal plane of symmetry containing the longitudinal axis of the propulsion power unit (1), and comprises a central compartment (7b) that is open on the top and on the bottom and provided for housing devices. The pylon is attached to the fuselage (5) by a distal edge (7d) extending parallel to the longitudinal axis of the propulsion power unit (1). The fairing device consists of an upper half-cowl (2) and a lower half-cowl (3) substantially symmetrical relative to said plane of symmetry, and lockable therebetween, in a closed position. The upper half-cowl (2) and lower half-cowl (3) are individually pivotably mounted on the distal edge (7d) of the pylon (7) such that, in an open position, access is provided at the same time to the engine (4) and to the central compartment (7b) of the pylon (7).

- 13. A fairing device for a propulsion power unit comprising a gas turbine engine, a nacelle, of which said fairing device forms a part, and which surrounds the engine, and a support structure known as a pylon for securing to a fuselage of an aircraft, said pylon running in a substantially horizontal plane of symmetry containing the longitudinal axis of the propulsion power unit, and comprising a central compartment open from the top and from the bottom, and designed to house equipment, said pylon being configured to be attached to the fuselage by a distal edge running parallel to the longitudinal axis of the propulsion power unit, the fairing device comprising at least an upper half-cowl and a lower half-cowl which are substantially symmetric with respect to said plane of symmetry and can be locked together, in the closed position, at their meeting point by a locking means, wherein at least one of said upper and lower half-cowls is mounted so as to be pivotable individually on said distal edge of the pylon so as, in the open position, to provide access both to the engine and to the central compartment of the pylon.
