Abstract
The present invention relates to a gas turbine engine which is provided with a thrust reverser with unfoldable doors and which is of the double jet type, i.e. comprising a central generator emitting a jet of hot gas and surrounded by an annular by-pass conduit through which a jet of relatively cold gas passes, wherein said turbine engine comprises means for restricting the passage of the jet of relatively cold gas in said annular by-pass conduit when the doors of the thrust reverser are unfolded. The invention results in a simplification of the structure of the doors of the thrust reverser.
Claims11
In a by-pass gas turbine engine comprising a central generator including a central jet exhaust pipe having an exit end adapted to emit a first jet of relatively hot gas;
- an annular by-pass conduit surrounding said central jet exhaust pipe, said by-pass conduit having an exit end adapted to emit a second annular jet of relatively cold gas enveloping said jet of relatively hot gas,
- a thrust reverser located downstream of the exit ends of said jet exhaust pipe and said by-pass conduit, said thrust reverser comprising doors movable between a folded position in which said doors are clear of said jets and an unfolded position in which said doors are disposed transversely in the path of said jets,
- the improvement comprising:
- restricting means for selectively obstructing a portion of the discharge outlet area of said exit end of said by-pass conduit through which said second jet is emitted,
- said restricting means and said reverser being coupled in operation such that said by-pass conduit is obstructed when said doors are unfolded.
