A vapor cycle compressor includes a motor section and a compression section operatively engaged with the motor section. A refrigerant path is in the motor section and in the compression section. The refrigerant path includes: a compression refrigerant path, for a single phase compression refrigerant, in the compression section; an inner rotor shaft refrigerant path, for a single phase inner rotor shaft refrigerant, in the compression section and in the motor section; and a stator refrigerant path, for a two phase stator refrigerant, in the motor section.

Multistage compressor having interstage refrigerant path split between first portion flowing to end of shaft and second portion following around thrust bearing disc

An environmental control system (ECS) having contaminants in supply air that flows into an environment includes an outside air contaminant component that senses contaminants in outside air, wherein the outside air contaminant component is upstream of the environment, A recirculated air contaminant component is provided and that senses contaminants in recirculated air supplied by the environment, wherein the recirculated air contaminant component is downstream of the environment. A voltage supply provides a non-linear variable voltage to at least one of the components. A controller is in communication with the components and the voltage supply; wherein, upon a measured resistance, from at least one of the components, that exceeds a threshold, the controller varies at least one of an outside air flow and a recirculated air flow in the ECS.

Adjustable sensor or sensor network to selectively enhance identification of select chemical species

An Environmental Control System may use an electronic particle separation system to control humidity in an aircraft. The electronic particle separation system may include a particle separator, a sensor module, and a controller configured to receive signals from the sensor module, and operate the particle separator based on the received sensor signals. In some embodiments, the controller may include a processor which may determine whether the particle separator is being operated under an ozone related condition exceeding a threshold operating condition. If one of the threshold operating conditions is exceeded, the particle separator may be turned off which may control the amount of ozone present in the aircraft.

Aircraft electrostatic particle separation control system

An Environmental Control System may use an electronic air treatment system to control humidity in an aircraft. The electronic air treatment system may use an electronic charging system and a separation system. A turbine rotor may drive a power generating stage to provide high voltage power to the electronic charging system. The charging stage may charge airflow passing through to repel liquid particles away from the airflow. Liquid droplets may be collected and centrifugally flung toward a periphery of the separation system. The liquid particles may be collected outside of the airflow, which may be allowed to pass through the separation system and out to a destination in the aircraft without the collected liquid.

Self-contained aircraft electronic air treatment system

An Environmental Control System may use an electronic particle separation system to control humidity in an aircraft. The electronic particle separation system may include a charging stage and a collecting stage. The charging stage may charge airflow passing through to repel liquid particles away from the airflow. Liquid droplets may be collected by the collecting stage and centrifugally flung toward a periphery of a separator. The liquid particles may be collected outside of the airflow which may be allowed to pass through the separator and out to a destination in the aircraft without the collected liquid.

Aircraft electronic particle separation system

A controlled start up technique may eliminate the excessive peak junction temperature by controlling the speed of the electric device. Lower speed may result in reduced power to the load. Reduced power may result in reduced losses to maintain reliable operating junction temperatures. Once the junction reaches the predetermined temperature limit, speed may be controlled to hold the junction temperature constant. As time elapses, the coolant temperature may reduce, thereby allowing a higher power level without an increase in IGBT temperature. Unlike conventional methods which may allow for full power continuously upon start up, thereby either potentially causing a high temperature shut-down condition or requiring additional thermal inertia to handle a high heat load due to a continuous full-power start up, the controlled start up eliminates the design penalties for extensive thermal enhancements to accommodate the occasional extreme hot start up.
