초록 ▼

A convergent/divergent gas turbine engine exhaust nozzle having reverse thrust capability includes a door which blocks a reverse flow outlet port when the nozzle convergent flap is in any forward thrust operating mode. The door is coupled to the convergent nozzle flap such that it opens as the conve

대표청구항 ▼

An exhaust nozzle assembly for an aircraft engine, said engine having a centerline and comprising: exhaust duct means including means defining reverse flow outlet means, said exhaust duct means having spaced apart stationary sidewall means; and an upper and lower flap assembly each including a nozzle flap having a forward edge and rearward edge, said nozzle flaps each extending between and pivotally secured to said sidewall means, said flaps being spaced apart and rotatable about respective parallel axes and forming between them a gas flow path having an exit area defined by said flap rearward edges and said sidewall means, said nozzle flaps being rotatable through a range of forward thrust positions and a range of reverse thrust positions including a full reverse thrust position wherein said rearward edges meet at said engine centerline and said exit area is reduced to zero, each flap assembly including: (A) blocker door means extending between and pivotally connected to said sidewall means and rotatable about said axis of said nozzle flap of its respective flap assembly from a closed position which blocks said outlet means to an open position which unblocks said outlet means, said respective nozzle flap including seal means along its forward edge in sealing contact with said blocker door means in all positions of said respective nozzle flap to prevent exhaust gases from escaping between said blocker door means and said respective nozzle flap; and (B) actuation means connected to said blocker door means and respective nozzle flap and adapted to (1) rotate said nozzle flap through its range of forward thrust positions and its range of reverse thrust positions; (2) maintain said blocker door means stationary and in its closed position as said respective nozzle flap moves through its range of forward thrust positions; and (3) rotate said blocker door means from its closed position to its open position about said respective nozzle flap axis as said nozzle flap is rotated through its range of reverse thrust positions, said respective nozzle flap adapted to direct the engine exhaust through said outlet means when said blocker door means is in its open position wherein said actuation means includes a cam track connected to said respective flap means for rotation therewith, said actuation means also including a cam follower and linkage means connected to said cam follower, said linkage means having a first end pivotally connected to one of said sidewall means and a second end operably connected to said blocker door means, said cam follower being disposed within said cam track, said cam track being adapted to maintain said linkage means substantially stationary as said flap means rotates through its range of forward thrust positions and adapted to move said second end of said linkage means to rotate said blocker door means to its open position as said flap means rotates through its range of reverse thrust positions.
