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.

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.
