Abstract: A power generation system including a housing defining a cavity and having an inlet for receiving a fluid that is used to cool and pressurize the cavity and an outlet for removing the fluid from the cavity. The system also may include a rotor having a first end positioned within the cavity of the housing and a second end, a plurality of bearings, positioned to contact the rotor, for providing radial support to the rotor, and a turbine connected to the second end of the rotor. Further, the system may include a heat sink positioned within the cavity and between the housing and the rotor, and an electronic component attached to the heat sink.

Abstract: One embodiment of the invention provides a turbine control system that adjusts the control thresholds of two-position valves, which provide propellant to the turbine, based on turbine load so as to compensate for increased turbine speed overshoot at low load and the increased turbine speed undershoot at high load. These two-position on-off modulated valves are used in a bang-bang (fully open or fully closed) regulation scheme to eliminate or minimize speed droop by using variable speed bounds implemented as a function of load.

Abstract: A method to desorb water from a desiccant of an air recharge system comprises the steps of a) filling a purge reservoir using an air compressor and a desiccant dryer to produce discharge air, b) stopping the air compressor; c) back purging the desiccant, and d) vent resetting the system, wherein the filling a purge reservoir step does not result in an addition of discharge air to an air storage tank in fluid communication with the purge reservoir and wherein the air storage tank is filled with an amount of the discharge air such that the air storage tank is at a full storage tank pressure prior to filling the purge reservoir. A method of filling an air storage tank of an air recharge system is also disclosed.
