Abstract
A start mechanism for a propulsion system including a receptacle in operative communication with a case; at least one portable source of energy disposed within the receptacle; a flow channel fluidly coupled to the receptacle; and a turbine flow path within the case, the turbine flow path fluidly coupled to the flow channel; wherein the at least one portable source of energy is configured to produce at least one of electrical energy and a source of chemical energy.
Claims20
A start mechanism for a propulsion system comprising:
- a receptacle in operative communication with a case;
- at least one portable source of energy disposed within the receptacle;
- a flow channel fluidly coupled to the receptacle;
- and
- a turbine flow path within the case, the turbine flow path fluidly coupled to the flow channel;
- wherein the at least one portable source of energy is configured to produce at least one of electrical energy and a source of chemical energy.
A gas turbine engine having a start mechanism comprising:
- a case supporting a turbine section having a turbine rotor;
- a receptacle in operative communication with a case;
- at least one battery disposed within the receptacle;
- a flow channel fluidly coupled to the receptacle;
- and
- a turbine flow path proximate the turbine rotor within the case, the turbine flow path fluidly coupled to the flow channel;
- wherein the at least one battery is configured to produce at least one of electrical energy and a source of chemical energy;
- wherein the source of chemical energy is configured, after initiation, to produce a converted chemical energy, wherein the converted chemical energy comprises a rapidly expanding fluid.
A process of forming a gas turbine engine having a start mechanism comprising:
- forming a case supporting a turbine section having a turbine rotor;
- forming a receptacle in operative communication with a case;
- disposing at least one battery within the receptacle;
- forming a flow channel fluidly coupled to the receptacle;
- forming a turbine flow path proximate the turbine rotor within the case;
- fluidly coupling the turbine flow path to the flow channel;
- configuring the at least one battery to produce at least one of electrical energy and a source of chemical energy;
- and
- configuring the source of chemical energy, after initiation, to produce a converted chemical energy, wherein the converted chemical energy comprises a rapidly expanding fluid.
