Abstract
A thrust reverser of a nacelle may include a translating sleeve and an inner fixed structure a pressure relief assembly. A pressure relief mechanism may include a pressure relief door coupled via a hinge and a latch to the inner fixed structure. Alternatively, a pressure relief door may be coupled to a frame via a hinge and a latch to the inner fixed structure. The pressure relief assembly may limit deflections between the thrust reverser and the pylon in response to a burst duct. The pressure relief door may release from the latch automatically in response to an over pressurization event.
Claims5
A nacelle comprising:
- an inner fixed structure;
- a pressure relief assembly comprising:
- a latch mechanism comprising a pressure relief latch pivotably coupled to the inner fixed structure;
- a first hinge coupled to the inner fixed structure;
- a pressure relief door coupled to and configured to pivot about the first hinge, the pressure relief door comprising a bracket, the pressure relief latch configured to hold the pressure relief door in a closed position, the bracket directly coupled to the pressure relief door, the pressure relief latch releasably coupled to the bracket, wherein:
- the pressure relief latch is configured to automatically release from the bracket and pivot radially outward about a hinge line defined by a second hinge in response to a pressure difference across the pressure relief door,
- the first hinge is coupled to the inner fixed structure proximate a first end of the pressure relief door, and
- the pressure relief latch is coupled to the inner fixed structure proximate a second end of the pressure relief door, the second end opposite the first end.
