Claims
- 1. A turbine support assembly comprising:
- a fan shaft having a forward end and an aft end;
- a turbine rotor having a plurality of stages of rotor blades extending radially outwardly therefrom;
- a support shaft including a frustrum having a base end fixedly joined to said turbine rotor, and a top end removably fixedly joined to said fan shaft aft end; and
- said fan shaft aft end being configured with said support shaft in a radially extending V-configuration including first and second legs having top and bottom ends joined together at said top ends thereof to define an apex, said first and second legs being inclined axially apart at an apex angle therebetween so that said bottom ends thereof are axially spaced apart, at least said first leg forming an integral part of said fan shaft with said first leg bottom end being integral with said fan shaft, and said turbine rotor being supported by said support shaft and said second leg.
- 2. A turbine support assembly according to claim 1 wherein said second leg is an integral part of said support shaft with said top end thereof being integrally joined to said frustrum top end and inclined axially inwardly therefrom at a diverging angle therebetween, said support shaft further including a cylindrical journal shaft fixedly joined to said second leg bottom end for rotatably supporting said second leg.
- 3. A turbine support assembly according to claim 2 wherein:
- said frustrum top end is disposed upstream of said frustrum base end; and
- said second leg extends downstream from said frustrum top end.
- 4. A turbine support assembly according to claim 3 further including:
- a fan fixedly joined to said fan shaft forward end;
- an annular casing having a plurality of stages of stator vanes extending radially inwardly therefrom, and disposed upstream of respective ones of said rotor stages in flow communication therewith; and
- a turbine frame disposed downstream of said turbine rotor, and including a conical hub extending upstream towards said frustrum for rotatably supporting said turbine rotor by said support shaft at said journal shaft.
- 5. A turbine support assembly according to claim 4 further including:
- a fan frame having a first bearing joined to said fan shaft for supporting radial loads therefrom; and
- said turbine frame having a second bearing joining said journal shaft to said turbine frame for supporting radial loads therefrom.
