Abstract

A nacelle ( 55 ) for a gas turbine engine ( 10 ), the engine ( 10 ) comprising accessories ( 34 ) mounted to a fan casing ( 28 ) and a core engine ( 9 ), the nacelle ( 55 ) substantially surrounds the engine ( 10 ) and comprises an intake ( 12 ) and a thrust reverser unit ( 31 ). The thrust reverser unit ( 31 ) is formed by two generally C-shaped portions ( 31 a, 31 b ). The thrust reverser unit ( 31 ) is openable to provide access to the accessories ( 34 ) and the core engine ( 9 ). The nacelle ( 55 ) further comprises a fan containment casing ( 33 ) that is integral with the intake ( 12 ).

Claims (9)

1. A nacelle for a gas turbine engine, the engine comprising accessories mounted to a fan casing and a core engine, the nacelle substantially surrounding the engine and comprising an intake and a thrust reverser unit, the thrust reverser unit being formed by two generally C-shaped and openable portions and with the thrust reverser unit housed within at least one of said C-shaped portions and including a radially outer wall of at least one of said C-shaped portions and characterized in that at least one of said C-shaped portions is openable to provide access to the accessories and the core engine.

2. A nacelle as claimed in claim 1 wherein the nacelle comprises a fan containment casing, the fan containment casing is integral with the intake.

3. A nacelle as claimed in claim 2 wherein the intake comprises an acoustic panel that extends between a downstream edge of the fan containment casing and a leading edge of the intake, thus reducing engine-generated noise.

4. A nacelle as claimed in claim 2 wherein the fan containment casing is disposed outside a fire zone of the nacelle.

5. A nacelle as claimed in claim 2 wherein at least one access panel is provided radially outwardly of the fan containment casing to allow access thereto.

6. A nacelle as claimed in claim 1 wherein at least one access door is provided in the C-shaped portions radially outward of the fan casing to allow access thereto.

7. A nacelle as claimed in claim 6 wherein at least one access door is pivotably attached to the C-shaped portions and is manually openable only when the C-shaped portions are closed.

8. A nacelle as claimed in claim 6 wherein at least one access door is pivotally attached to the C-shaped portion, and the pivotal attachment is positioned near a horizontal line of the C-shaped portion such that the access door hangs open in a near vertical position allowing engine access.

9. A nacelle as claimed in claim 6 wherein at least one access door is pivotally attached to the C-shaped portion, and the pivotal attachment is positioned in a lower quadrant of the C-shaped portion such that the access door hangs open in a near vertical position allowing engine access.
