Claims22
A gas turbine engine frame, comprising:
- a metallic inner hub;
- a metallic outer construction;
- and
- a composite flowpath disposed between said metallic inner hub and said metallic outer construction, said composite flowpath defining a primary flowpath for a working fluid of the gas turbine engine.
1 more element
A gas turbine engine, comprising:
- a compressor;
- a turbine;
- and
- an engine frame, said engine frame including a metallic load-bearing structure and a composite flowpath, wherein said metallic load-bearing structure defines a loadpath operative to transmit engine mechanical loads to an engine mount of the gas turbine engine, and wherein said composite flowpath is divorced from the loadpath.
1 more element
A gas turbine engine, comprising:
- a compressor;
- a turbine;
- and
- an engine frame, said engine frame including:
- composite means for defining a primary flowpath for a working fluid of the gas turbine engine;
- and
- means for transmitting engine mechanical loads to an engine mount of the gas turbine engine,
- wherein said composite means are divorced from the engine mechanical loads.
