An HVAC system has a duct with an inlet and an outlet. A first supercharger is disposed in the duct. A second supercharger is disposed in the duct in parallel with the first supercharger. A gearbox has a first output shaft coupled to the first supercharger and a second output shaft of the gearbox coupled to the second supercharger. A first evaporation coil is disposed in the duct between the supercharger and inlet. A second evaporation coil is disposed in the duct between the supercharger and outlet. A heater is disposed in the duct between the supercharger and outlet.

High efficiency flight line cooling, heating, and dehumidification system

An HVAC system is monitored or tested using a tube with a measurement instrument in the tube. The tube is connected to an HVAC system and an output of the HVAC system is measured using the measurement instrument. The tube is connected between the HVAC system and a volume to be conditioned. A reading of the measurement instrument is noted while the tube is connected between the HVAC system and volume. The volume is disconnected from the tube and a valve is connected to the tube. The valve is adjusted until the reading of the measurement instrument is approximately the same with the valve as when the volume was connected. A setting of the valve is noted and then used to test the HVAC system in the future or to test other HVAC systems simulating the same load.

A heating, cooling, and power device includes a shaft and an expander coupled to the shaft to rotate the shaft. A first conduit is coupled to the expander and configured to transport a working fluid. A heater is coupled through the first conduit to the expander. A heat pump is coupled to the shaft. An electric machine is coupled to the shaft to produce electricity or mechanical shaft power. A recuperator includes a second conduit coupled between the expander and recuperator. The heat pump includes a first heat exchanger including a second conduit coupled between the expander and the first heat exchanger. An expansion device includes a third conduit coupled between the first heat exchanger and the expansion device. A second heat exchanger includes a fourth conduit coupled between the expansion device and second heat exchanger. A compressor is coupled to the shaft.

Integrated power, cooling, and heating device and method thereof

The present invention provides an apparatus for utilizing waste heat to power a reconfigurable thermodynamic cycle that can be used to selectively cool or heat an environmentally controlled space, such as a room, building, or vehicle. The present invention also integrates an electric machine, which may operate as a motor or generator, or both, and an additional prime mover, such as an internal combustion engine. Different combinations of these components are preferable for different applications. The system provides a design which reasonably balances the need to maximize efficiency, while also keeping the design cost effective.

Integrated power, cooling, and heating apparatus utilizing waste heat recovery

A fuel metering system for supplying fuel to load includes a variable displacement piston pump having an adjustable hanger that is movable to a plurality of positions. The variable displacement piston pump is configured to receive a drive torque and, upon receipt of the drive torque, to supply fuel to the plurality of loads at a flow rate dependent on the position of the adjustable hanger. A hanger actuator is coupled to receive hanger position commands and is operable, in response thereto, to move the adjustable hanger to the commanded position.

Fuel metering system electrically servoed metering pump

A tachometer for supplying a signal representative of the rotational rate of a rotatable device includes a plurality of detection magnets, an index feature, and one or more non-rotationally mounted magnetic circuits. The detection magnets are coupled to, and spaced around, the device, to thereby rotate with the device when the device is rotated. The index feature is associated with the rotatable device, to thereby rotate with the device when the device is rotated. The index feature and the plurality of detection magnets are spaced evenly around the device. The magnetic circuits are spaced evenly around the device, and each magnetic circuit is configured to supply a first electrical signal each time one of the detection magnets rotates past the magnetic circuit and a second electrical signal each time the index feature rotates.

A modular electromechanical actuation system assembly is provided that includes an electronic control unit housing having a plurality of motor receptacles and a plurality of battery receptacles formed in an outer surface thereof. Each of the motor receptacles has an associated motor electrical interface, and each of the battery receptacles has an associated battery electrical interface. An electronic control unit is disposed within the electronic control unit housing and is electrically coupled to each of the motor electrical interfaces and each of the battery electrical interfaces. A plurality of motors are supported, one each, within one of the motor receptacles, and a plurality of batteries are supported, one each, within one of the battery receptacles.

Modular, harnessless electromechanical actuation system assembly

Electromechanical actuation systems and methods are provided. The electromechanical actuation system includes first, second, and third linear actuators having respective first, second, and third ranges of motion and an output member coupled to the first, second, and third linear actuators such that a position of a selected portion of the output member is based on actuation of the first, second, and third linear actuators.

Electromechanical actuation system and method

A fault-tolerant position feedback filter may be used in an actuation control system to limit the authority of a first position signal, should the first position signal become erroneous, and thereby prevent a postulated runaway condition of an acuator. The filter includes a difference function, a limited integrator, and a summer. The difference function supplies a first position error signal representative of a mathematical difference between a first position signal and a combined position signal. The limited integrator supplies an integrated position error signal that is limited in magnitude to a predetermined limit. The summer supplies the combined position error signal that is representative of a mathematical sum of the integrated position error signal and the second position signal.

Fault-tolerant control system

A system and method of implementing servomechanism control without rate feedback is provided. A position feedback signal is filtered using a non-linear lead-lag filter that has a variable frequency response to thereby generate a compensated position feedback signal. A position error signal is generated from a position command signal and a sensed position signal, and the frequency response of the non-linear lead-lag filter is varied in response to the position error signal. A compensated position error signal is generated from the commanded position signal and the compensated position feedback signal. The compensated position error signal is at least selectively filtered using a non-linear integral filter that has a variable gain to thereby at least selectively supply a filtered position error signal. The gain of the non-linear integral filter is varied in response to the compensated position error signal.

Adaptive servo control system and method

A system and method are provided for supplying electromechanical actuator (EMA) health status information to a control system. A determination is made as to whether the EMA has experienced a fault. If the EMA has experienced a fault, a fault-based position limit and a fault-based rate limit of the EMA are determined, based on the fault. A design position limit and a design rate limit of the EMA are supplied. An updated position limit of the EMA is determined based on at least the design position limit and the fault-based position limit, and an updated rate limit of the EMA is supplied based on at least the design rate limit and the fault-based rate limit.

The test system control supplies the first actuator commands and the second actuator commands.
