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 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.

A compact heat battery (CHB) may comprise a casing, a tube containment sheath, a bundle of hermetically sealed phase change material (PCM) encapsulation tubes, and encapsulation tube inserts. An insulation envelope and insulation shield may be positioned radially outward from the casing. As an alternative the casing, insulation, and insulation shield can be integrated into a double-walled vacuum cylinder. The cylindrical containment sheath can open and close along a split-seam in response to radial expansion of the tubes. The natural packing of the encapsulation tubes within the containment sheath can distribute a heat transfer fluid through the interstitial spaces between the encapsulation tubes. Floating baffle plates provide for axial containment and expansion of the encapsulation tube bundle. The CHB of the present invention can allow for increased tube density, providing increased heat absorption and decreased CHB dimensions. The encapsulation tube inserts can provide slip planes to reduce expansive loading of the encapsulation tube walls during solid phase transition.
