An air conditioning pack management system for controlling distribution of a predetermined amount of conditioned air from a system comprising two or more air conditioning packs, the pack management system comprising a management unit arranged to proportion the predetermined amount of conditioned air to be provided by one or more of the two or more packs based on the respective operating efficiencies of the packs or other pre-selected metrics.

Pack management system for environmental control system

Aircraft systems including a pressurized fuel tank containing a pressurized fuel, a turbo expander configured to receive the pressurized fuel from the fuel tank, the turbo expander configured to decrease a pressure of the pressurized fuel to generate low pressure fuel having pressure less than the pressurized fuel, a fuel-to-air heat exchanger configured to receive the low pressure fuel from the turbo expander as a first working fluid and air as a second working fluid, the heat exchanger configured to cool the air and warm the fuel, an aircraft cabin configured to receive the cooled air, and a fuel consumption system configured to consume the fuel to generate power.

Hydrogen systems for environmental control systems onboard aircraft

A method and system for controlling fresh air flow into a controlled environment are disclosed herein. The method comprises: measuring, using a sensor, a predetermined property in the controlled environment; estimating, by a controller, a number of people inside the controlled environment based on the measured property, and setting, by the controller, a rate of fresh air flow to the controlled environment based at least in part on the estimated number of people inside the controlled environment.

Environmental control system

An airplane is provided. The airplane includes a fuel gauging and quantity estimation system with an improved estimation accuracy. The fuel gauging and quantity estimation system operates by detecting an environment of a tank comprising a liquid and selecting one or more liquid gauging algorithms based on the environment. The fuel gauging and quantity estimation system further operates by receiving sensor data characterizing the liquid of the tank and utilizing the sensor data and the one or more liquid gauging algorithms to determine a property of the liquid.
