Gas turbine generator with a pre-combustion power turbine

A turbine generator comprising:

• a combustion chamber;
• a high-speed spool comprising a high-speed turbine downstream of the combustion chamber to receive power therefrom, the high-speed turbine operatively coupled to a high-speed compressor assembly upstream of the combustion chamber;
• a low-speed spool comprising a pre-combustion power turbine directly upstream of the combustion chamber and directly downstream of the high-speed compressor assembly to receive power therefrom;
• and
• an electrical generator located radially outside of the low-speed bearing assembly and between the pre-combustion power turbine and the high-speed turbine, the electrical generator comprising a rotor assembly operatively coupled to the pre-combustion turbine.

A turbine generator comprising:

• a combustion chamber;
• a high-speed spool comprising a high-speed turbine downstream of the combustion chamber to receive power therefrom, the high-speed turbine operatively coupled to a compressor impeller upstream of the combustion chamber;
• a low-speed spool comprising a post-combustion power turbine upstream of the high-speed turbine and downstream of the combustion chamber to receive power therefrom;
• and
• an electrical generator comprising a rotor assembly operatively coupled to the post-combustion turbine, the rotor assembly operatively coupled to a pre-combustion turbine upstream of the combustion chamber and directly downstream of the compressor impeller to receive power therefrom.
