Abstract
A mount system for a gas turbine engine includes an aft mount which reacts at least a portion of a thrust load at an engine case generally parallel to an engine axis.
Claims18
A mount system for a gas turbine engine comprising:
- an aft mount which reacts at least a portion of a thrust load at an engine case generally parallel to an engine axis, wherein said aft mount comprises:
- a rear mount platform;
- a waffle tree assembly;
- a first A-arm mounted to said rear mount platform through a first ball joint and said waffle tree assembly through a first sliding ball joint;
- and
- a second A-arm mounted to said rear mount platform through a second ball joint and said waffle tree assembly through a second sliding ball joint.
3 more elements
A mount system for a gas turbine engine comprising:
- a pylon;
- an engine case defined about an engine axis of rotation;
- a rear mount platform attached to said pylon;
- a wiffle tree assembly mounted to said pylon through a first wiffle tree ball link;
- a first A-arm mounted to said rear mount platform through a first A-arm first ball joint, said wiffle tree assembly though a first A-arm sliding ball joint and said engine case through a first A-arm second ball joint;
- and
- a second A-arm mounted to said rear mount platform through a second A-arm first ball joint, said wiffle tree assembly though a second A-arm sliding ball joint and said engine case through a second A-arm second ball joint.
4 more elements
A method for mounting a gas turbine engine comprising an engine case which at least partially surrounds a turbine section, and a pylon, comprising:
- positioning a rear mount platform of an aft mount between the engine case and the pylon to react a least a vertical load, a side load and a thrust load;
- connecting a first and second A-arm of the aft mount between the rear mount platform and the engine case through a respective ball joint to react a thrust vector of the thrust load at the engine case generally parallel to an engine axis;
- and
- connecting a wiffle tree assembly between the first and second A-arm and the pylon through though a respective sliding ball joint to react only a vertical load transverse to the engine axis.
