A low cost, high power density, low emissions general aviation turbine engine (GATE) with improved fuel economy over current engines. Ideally suited for 50 to 500 shaft horsepower (SHP) range aircraft applications such as GA, UAS, UAS, air taxi, helicopters and commercial markets. The engine design features with centrifugal compressor and radial turbine rotors has a high-end practical limit of ˜800 (SHP). The new turboprop incorporates 2 non-concentric spools aero-thermal-pressure coupled wherein staged compressor rotors lend to a simple engine design, optimized high overall engine pressure ratio (OPR) and low specific fuel consumption (SFC). An integral starter—generator system further simplifies the engine design and offers high electrical output power capability for auxiliary power requirements. A 2-stage low emissions combustor with fuel-air premix chambers is incorporated lending to stable combustion at any engine spool speed/power requirement, further fuel optimization and use of a low cost simple fixed pitch propeller. Some other highlights include: any fuel or mixture thereof, TBO greater than piston or other turbine engines, less maintenance costs, oil/filter change at ˜15000 hrs. and other inherent advantages of a gas turbine engine. Of the two spools that make up this turboprop engine, one is the High Pressure (HP) spool that is part of the gas generator using combustor hot gases to power the integral HP turbine rotor, HP compressor and high-speed alternator starter—generator. The other engine spool is the Low-Pressure (LP) spool that receives the HP turbine exhaust heat energy to power the integral LP compressor rotor, LP turbine rotor, integrated gearbox with resultant output shaft horsepower. This invention represents the most advanced engine for general aviation since Charles Edward Taylor's engine powered the Wright Brothers first aircraft-controlled powered flight Dec. 17, 1903.

An improved fuel air premix chamber for a gas turbine engine. An integral heat exchange structure is used to cools the premix chamber outer wall, preheating the compressor air supply as it passes into an inner central longitudinal premix tube and preheating also the fuel and F/A mixture for an improved mix, low emissions combustion and low differential combustor pressure. The F/A premix flow thru the central longitudinal tubes and yields an exiting spouting velocity into the primary combustion zone for swirl/circumferential flow combustion yielding flame stability.

A double annular radially staged combustor for a gas turbine engine having a reduced internal flow transitioning area between an outboard primary combustion zone and al inboard secondary combustion zone. The primary combustion zone is an annular shell form with a radially inboard annular exit. An outboard ring with thru holes and an inboard annular channel yields a quick quench zone. The secondary combustion zone, adjacent to and downstream of the quick quench zone is of an annular shell form, generally radially inboard of the primary combustion zone. In a preferred embodiment the secondary combustion zone exiting hot gases flows into a dilution zone prior to exiting the combustor.

The invention relates electrical power generation using renewable sun energy in a Microturbine Sun Tracker (MST), a system for useful electrical output power that combines a Concentrated Solar Energy (CSE) with a closed cycle Microturbine powerplant. The solar light ray energy of the CSE is directed into a solar receiver with an integrated closed cycle microturbine powerplant, heating the working fluid of the microturbine to cause the turbine rotor/power spool rotation and subsequent output electricity. Also the (MST) system combines the dish form (CSE) and the closed cycle microturbine powerplant to a common frame that incorporates a single axis 360&#xb0; rotation capability and secondary declination tilting capability.

This invention relates to a hybrid gas turbine (HGT) engine powerplant having electrical output power and as a system independently or in combination with electrical energy storage means, supplies electrical power to at least one electric motor for vehicular propulsion. The HGT has a minimum of two spools at least one spool, the power spool, has integrated a compressor rotor, turbine rotor and alternator rotor; a minimum second spool for staged engine air compression has integrated a compressor and turbine rotors aero-coupled to the power spool. An electronic engine unit (EECU) supplies electrical power to the fuel control valve, has preprogrammed variable power spool speeds per output power requirements, exhaust gas turbine temperature limits for fuel economy considerations and is responsive thru vehicle throttle commands of accel, decel, constant vehicle operations, start-up, shut down, battery charger and auxiliary power applications (APU).

A hybrid microturbine to produce electrical output power within a engine housing, having a combustor, and a two spool multi stage compressor wherein the 1st spool has a compressor rotor and a turbine rotor as a turbocharger and the 2rotor spool has an alternator rotor integrated with a compressor rotor and turbine rotor. The two individual compressor rotors have rotating blades attached and located in compressor housings with fluid communication. The alternator rotor as part of the 2spool has permanent magnets integrated and positioned in close proximity and co-axial to the electrical stator module having an iron laminated structure with electrical wires. Relative rotational motion between the stator and alternator rotor cause electricity to be generated.

A power plant with a CHP system having a distillation apparatus to yield a high thermally efficient electrical power plant for reduced fuel usage and subsequent lower CO2 emission specie. The incorporation of a Combined Heat and Power (CHP) system with a microturbine, makes use of the low emissions gas turbine exhaust gas waste heat of this electrical power generation plant for distillation processes, replacing the current use of electrical heating elements of the distiller unit. The inventive device includes a distiller apparatus and a microturbine gas turbine electrical power plant, a heat exchanger device where the exhaust gas waste heat energy of a gas turbine power plant passes thru one side of a series of plates/sheets of material and or tubes and heats the process fluids on the opposite side and also a surface area condenser is incorporated to reduce the product vapor state to a liquid.
