The lifting surface includes a control surface, a maneuvering system for displacing the control surface and sensors which measure a dimensional characteristic linked to the distortion of the lifting surface. The method acquires characteristic data linked to the distortion of the lifting surface, determines a set of values of the shape, analyzes the value of the strain attribute and compares the set of values characterizing the shape to the values of the tolerance interval associated with the lifting surface. If the set of values characterizing the shape is outside of the interval, the process triggers an activation of the maneuvering system to displace the control surface from an initial position in order to alleviate the loads on the lifting surface.

  • Patent number: 10527321
    Abstract: In an air cooled chiller, a refrigerant pump and bypass valve connected in parallel feed refrigerant from the condenser to a receiver; the pump is activated in response to condenser pressure; and the bypass is used otherwise. The condenser fan is controlled based on power consumption by the air cooled chiller that varies with ambient conditions. An evaporator set point is reset to meet load conditions. An expansion valve for the evaporator is controlled based on chilled water temperature, Delta T, or information from an air handling unit. Feedback of valve setting or position, temperature of air, valve size, and/or importance of an air handling unit is used to control the flow of chilled water. A variable pressure curve or other relationship is used with the feedback to control flow of chilled water based on the load. Refrigerant temperature is controlled based on information from the air handling unit.

  • Patent number: 10426059
    Abstract: Methods, systems and devices are provided for configuring an airflow cooling system shared by a plurality of IHSs (Information Handling Systems). An initial fan speed is set by a chassis manager that controls airflow cooling shared by the IHSs. The chassis manager broadcasts the initial fan speed to the plurality of IHSs. Each IHS receives the initial fan speed broadcast and determines its own fan speed requirements. If an IHS requires a fan speed greater than the initial fan speed, the IHS broadcasts a fan speed request. Each IHS continues to monitor fan speed broadcasts and broadcasts a request if its determined fan speed is greater than the most recent broadcast. The IHS that broadcasts the greatest fan speed request is designated as the dominant IHS. The chassis manager sets the airflow cooling system fan speed based on the fan speed requests broadcast by the dominant IHS.
