Abstract
An electricity generating system having a body (159), an annular combustor (14), a turbine (16), a compressor chamber and a compressor (102) positioned within the compressor chamber. An inlet port is in fluid communication with the compressor chamber and an exit port is in fluid communication with the turbine. A plurality of magnets (MG) is secured to the rotor (18) and a stator (22) made of mangnetically attracted material, such as iron, and having a stator winding provided in the body (159). The stator winding is positioned in close proximity to the plurality of magnets mounted to the rotor whereby rotation of the rotor (18) induces a current in the winding.
Claims18
An electricity generating system, comprising:
- a body;
- a combustor provided in said body;
- a turbine made of a plurality of turbine blades secured to a rotor, provided in said body and in fluid communication with said combustor;
- a compressor chamber provided in said body and in fluid communication with said combustor;
- a plurality of compressor blades secured to said rotor, said compressor blades positioned within a compressor chamber;
- an air inlet port in fluid communication with said compressor chamber;
- an exit port in fluid communication with said turbine;
- a plurality of magnets secured to said rotor;
- and
- a stator made of a magnetically attracted material provided in said body, said stator positioned in close proximity to said plurality of magnets whereby rotation of said rotor causes a change in flux about said stator thereby generating electricity;
- and
- a fuel metering valve in fluid communication with said combustor, wherein said fuel metering valve comprises a proportional solenoid having a plunger having a tip, said plunger adapted to extend along a longitudinal axis, a valve body defining a plunger cavity, an inlet and an outlet, said plunger extending within said plunger cavity, and a flow plate having a hole defined therein, said flow plate secured to said valve body and positioned within said plunger cavity between said inlet and said outlet whereby movement of said plunger in a first longitudinal direction causes said tip to coact with the hole defined in said flow plate to vary a flow from said inlet to said outlet through said hole defined in said hole plate.
