Abstract
A propulsion system of an aircraft includes an inner fixed structure (IFS) and the outer sleeve that may be separately coupled to the pylon. For instance, the inner fixed structure and the outer sleeve may move independently with respect to each other. A single latch of the latching system disclosed herein, may be configured to latch all 4 panels, (e.g. both halves of the IFS and both doors of the outer sleeve) together and/or in a closed and retained position.
Claims15
A latch system configured for a thrust reverser assembly of an engine nacelle comprising:
- a first outer sleeve door and a second outer sleeve door each mounted for movement between an outer sleeve door open position and an outer sleeve door closed position:
- a first inner fixed structure half and a second inner fixed structure half each mounted for movement between an open position and a closed position, wherein the first inner fixed structure half and the second inner fixed structure half are configured for independent kinematic movement from the independent kinematic movement of the first outer sleeve door and the second outer sleeve door, and wherein in response to the first outer sleeve door and the second outer sleeve door being in a closed position, the first inner fixed structure half and the second inner fixed structure half are retained such that kinematic movement between the open position and the closed position of the first inner fixed structure half and the second inner fixed structure half is prevented.
A system comprising:
- a first outer sleeve door;
- a second outer sleeve door;
- a first inner fixed structure half;
- and
- a second inner fixed structure half,
- wherein the first inner fixed structure half is configured for independent kinematic movement from the kinematic movement of the first outer sleeve door;
- wherein the second inner fixed structure half is configured for independent kinematic movement from the kinematic movement of the second outer sleeve door, and wherein in response to the first outer sleeve door and the second outer sleeve door being latched together, kinematic movement of the first inner fixed structure half and the second inner fixed structure half is prevented.
