Abstract
A geared architecture with a flex mount for a Fan Drive Gear System defined by a transverse stiffness relationship.
Claims28
A geared architecture for a gas turbine engine comprising:
- a fan shaft;
- a frame which supports said fan shaft, said frame defines a frame transverse stiffness;
- a gear system which drives said fan shaft;
- a flexible support which at least partially supports said gear system, said flexible support defines a flexible support transverse stiffness with respect to said frame transverse stiffness;
- and
- an input coupling to said gear system, said input coupling defines an input coupling transverse stiffness with respect to said frame transverse stiffness.

A geared architecture for a gas turbine engine comprising:
- a fan shaft;
- a frame which supports said fan shaft;
- a gear system which drives said fan shaft, said gear system includes a gear mesh that defines a gear mesh transverse stiffness;
- a flexible support which at least partially supports said gear system, said flexible support defines a flexible support transverse stiffness with respect to said gear mesh transverse stiffness;
- and
- an input coupling to said gear system, said input coupling defines an input coupling transverse stiffness with respect to said gear mesh transverse stiffness.
