A microturbine power generating system includes a reservoir that is pressurized with compressor air during system operation. The pressurized air in the reservoir is used to purge combustor fuel nozzles of residue after combustion in the combustor has ceased.

Compressor bleed pressure storage for controlled fuel nozzle purging of a turbine power generating system

A microturbine power generating system includes an electrical generator and a turbine having a fixed inlet nozzle geometry. Maximum thermodynamic efficiency of the microturbine power generating system is achieved by maintaining the turbine inlet at or near maximum temperature. When power demanded of the system is constant, power is supplied by the electrical generator. When an increase in power is demanded, at least a portion of the entire demand is supplied by a battery or other energy storage device until the electrical generator can satisfy the increased power demand. Conversely, when a decrease in power is demanded, the load on the generator is temporarily increased (effectively putting a brake on the generator and turbine) and such load is absorbed by the battery or other energy storage device.

Constant turbine inlet temperature control of a turbine power generating system

A microturbine power generation system includes an electrical generator, a turbine and a compressor intermediate the generator and the turbine. The turbine, compressor and electrical generator are secured together by a tieshaft. The tieshaft is prestressed such that faces of the turbine, electrical generator and compressor maintain contact during high-speed, high-temperature operation of the system.

An auxiliary system includes a plurality of devices that are driven by ac motors. A plurality of independently controllable isolators couple phase windings of the ac motors directly to phase windings of the electric generator. When an isolator connects the phase windings of its corresponding ac motor to the windings of the electric generator, the ac motor is operated directly on a high frequency unconverted output of the electric generator. Motor speed is determined by the number of poles on the ac motor relative to the number of poles of the electric generator. Pole-switching allows the speed of the motor to be varied.

An environmental control system for ground vehicles and low flying aircraft that supplies purified and conditioned ambient air to the vehicle's crew compartment is provided. The system integrates catalytic and particulate filters, that remove nuclear, biological, and chemical warfare agents from ambient air, with a source of compressed ambient air, and an air cycle refrigeration unit.
