Abstract
Systems for thrust reverser link arm connections are described herein. A fitting for a thrust reverser link arm may comprise a base plate configured to be fastened to a proximal surface of an inner fixed structure (IFS), a first wall extending orthogonally from the base plate, a pin extending orthogonally from the first wall, a second wall extending orthogonally from the base plate, a removable member, a first column located between the first wall and the second wall, and a second column located between the first wall and the second wall. The removable member may surround at least a portion of the pin. The removable member may be removed from a radially outward side of the IFS.
Claims15
A nacelle for a gas turbine engine comprising:
- an inner fixed structure (IFS);
- and
- a fitting for a link arm, the fitting being attached to a proximal surface of the IFS, the fitting comprising:
- a base plate configured to be fastened to a proximal surface of the IFS,
- a first supporting wall extending orthogonal from the base plate,
- a second supporting wall extending orthogonal from the base plate,
- a pin extending orthogonally from the first wall, wherein the link arm pivotally rotates about the pin,
- a removable member for preventing the link arm from detaching from the pin, the removable member being removably accessible from a radially outward side of the IFS,
- a first column located between the first wall and the second wall, and
- a second column located between the first wall and the second wall,
- wherein the removable member is attached to the second wall and the first column via a first removable member fastener, the removable member located between the second wall and the first column, and the removable member is attached to the second wall and the second column via a second removable member fastener, the removable member located between the second wall and the second column.
A fitting for a thrust reverser link arm comprising:
- a base plate configured to be fastened to a proximal surface of an inner fixed structure;
- a first wall extending orthogonally from the base plate;
- a pin extending orthogonally from the first wall;
- a second wall extending orthogonally from the base plate;
- a removable member;
- a first column located between the first wall and the second wall;
- and
- a second column located between the first wall and the second wall,
- wherein the removable member is attached to the second wall and the first column via a first removable member fastener, the removable member located between the second wall and the first column, and the removable member is attached to the second wall and the second column via a second removable member fastener, the removable member located between the second wall and the second column.
A nacelle arrangement comprising:
- an inner fixed structure (IFS);
- a thrust reverser blocker door;
- a thrust reverser link arm coupled to the thrust reverser blocker door;
- a fitting coupled to the thrust reverser link arm, the fitting being attached to a proximal surface of the IFS, the fitting comprising:
- a base plate fastened to the proximal surface of the IFS;
- a first wall extending orthogonally from the base plate in a distal direction;
- a pin extending orthogonally from the first wall, the pin comprising a first end coupled to the first wall and a second end;
- a second wall extending orthogonally from the base plate;
- a removable member surrounding at least a portion of the second end of the pin,
- a first column located between the first wall and the second wall, and
- a second column located between the first wall and the second wall,
- wherein the removable member is attached to the second wall and the first column via a first removable member fastener, the removable member located between the second wall and the first column, and the removable member is attached to the second wall and the second column via a second removable member fastener, the removable member located between the second wall and the second column,
- the removable member configured to transfer a load from the pin into the IFS in response to the thrust reverser blocker door being deployed, the removable member being removable from a radially outward side of the IFS.
