  • Ram flow control with predicted ram air flow
    Patent number: 10618662
    Abstract: A system and method includes a heat exchanger, a ram inlet actuator, and a controller. The ram inlet actuator is configured to control ram air flow from a ram air inlet to the heat exchanger, and the heat exchanger is configured to provide cooling for a bleed air flow. The controller is configured to determine a predicted ram flow based on a bleed air temperature drop across the heat exchanger, a flow rate of the bleed air flow, and a ram air temperature at the ram air inlet. The controller is configured to control the ram inlet actuator based on the predicted ram flow.

  • Ambient condition based adjusting of cabin pressure to achieve target aircraft inflow
    Patent number: 9493243
    Abstract: Embodiments relate to adjusting cabin pressure based on ambient conditions to achieve a target aircraft inflow. An aspect includes receiving a number of occupants on an aircraft. The ambient conditions on the aircraft are monitored and an occupant threshold limit is determined for the aircraft based on the ambient conditions. If it is determined that the number of occupants exceeds the occupant threshold limit, the cabin pressure is reduced in the aircraft according to embodiments. The cabin pressure in the aircraft is reset in response to the occupant threshold limit being increased due to changing ambient conditions.
