Abstract
A method and system for bleed flow power generation is provided. The engine includes a core flowpath formed by a compressor section, a heat addition system, and an expansion section in serial flow arrangement. A bleed circuit is extended from the core flowpath to extract a portion of compressed fluid from the core flowpath. The method and system include bleeding compressed fluid through a bleed circuit extended in fluid communication from the core flowpath of the engine; flowing the compressed fluid through the bleed circuit to a turbine rotor positioned at the bleed circuit; extracting, via the turbine rotor, energy from the flow of compressed fluid across the turbine rotor; and receiving energy at an electric machine operably coupled to the turbine rotor.
Claims15
A method for bleed flow power generation for an engine, the engine having a core flowpath formed by a compressor section, a heat addition system, and an expansion section in serial flow arrangement, the engine further having a bleed circuit extended from the core flowpath to extract a portion of compressed fluid from the core flowpath, the method comprising:
- bleeding a compressed fluid through the bleed circuit extended in fluid communication from the core flowpath of the engine;
- flowing the compressed fluid across a turbine rotor that is in fluid communication with the bleed circuit;
- extracting, via the turbine rotor, energy from the flow of the compressed fluid across the turbine rotor;
- receiving energy at an electric machine operably coupled to the turbine rotor;
- and
- detecting failure of the bleed circuit, wherein detecting failure of the bleed circuit comprises:
- determining whether the speed of the turbine rotor corresponds to a predetermined speed range based on the operating condition of the engine, wherein failure of the bleed circuit is determined when the speed of the turbine rotor does not correspond to the predetermined speed range based on the operating condition of the engine.
