Abstract
Dual function links for gas turbine engine mounts are disclosed. An example apparatus for mounting a casing of a gas turbine engine to a pylon, the apparatus includes a first pin and a linkage including a first linkage portion including the first pin, a second linkage portion, the second linkage portion forming a first load path between the gas turbine engine and the pylon, the second linkage portion arranged with respect to the first linkage portion such that a gap prevents the first linkage portion from forming a second load path between the gas turbine engine and the pylon.
Claims20
An apparatus to mount a casing of a gas turbine engine to a pylon, the apparatus comprising:
- a first pin;
- and
- a linkage including:
- a first linkage portion including the first pin, the first linkage portion having a first stiffness;
- and
- a second linkage portion, the second linkage portion forming a first load path between the gas turbine engine and the pylon, the second linkage portion arranged with respect to the first linkage portion such that a gap prevents the first linkage portion from forming a second load path between the gas turbine engine and the pylon, the second linkage portion having a second stiffness, the second stiffness less than the first stiffness.
A gas turbine engine coupled to a pylon, the gas turbine engine defining a roll axis, a yaw axis, and a pitch axis, the gas turbine engine comprising:
- a casing;
- a mount to couple the casing to the pylon, the mount including:
- a first pin;
- and
- a first linkage portion including the first pin;
- and
- a second linkage portion, the second linkage portion forming a first load path between the gas turbine engine and the pylon, the second linkage portion arranged with respect to the first linkage portion such that a gap prevents the first linkage portion from forming a second load path between the gas turbine engine and the pylon, wherein the first linkage portion and the second linkage portion are unitary.
A gas turbine engine coupled to a pylon, the gas turbine engine defining a roll axis, a yaw axis, and a pitch axis, the gas turbine engine comprising:
- a casing;
- a mount to couple the casing to the pylon, the mount including:
- a first pin;
- a second pin;
- a third pin;
- and
- a fourth pin;
- a first linkage portion including the first pin, the first linkage portion including:
- a first member;
- and
- a second member, the first member and the second member forming a first clevis with the first pin and the pylon, the first member and the second member forming a second clevis with the second pin and the casing;
- a second linkage portion, the second linkage portion forming a first load path between the gas turbine engine and the pylon, the second linkage portion arranged with respect to the first linkage portion such that a gap prevents the first linkage portion from forming a second load path between the gas turbine engine and the pylon, the second linkage portion further including;
- a third member;
- and
- a fourth member, the third member and the fourth member forming a third clevis with the third pin and the pylon, the third member and the fourth member forming a fourth clevis with the fourth pin and the casing.
