  • Patent number: 8365762
    Abstract: A control system for transferring fluid between a fluid supply and a process. The control system includes a transfer controller, which outputs a transfer signal that corresponds to a time varying fluid transfer rate, and plural valves that are plumbed in parallel for connection between the fluid supply and the process. Each valve has a corresponding input to receive an actuation signal that enables a closed state or an open state. The system also includes plural means for limiting the rate of fluid flow corresponding to the plural valves, and a valve drive that is coupled to the corresponding inputs of the plural valves, which operates to generate a sequences of valve actuation signals that result in a combined fluid flow rate through the plural valves selected to track the time varying fluid transfer rate defined by a modulated transfer signal within a margin of error.

  • Publication number: 20100032525
    Abstract: The invention relates to a deflector for an aircraft, comprising a discharge pipe for leading a fluid to be drained from the aircraft by way of an outlet end to the environment of the aircraft; an actuator, coupled to the discharge pipe, for swinging out, when required, the discharge pipe to at least one activation position, wherein in the activation position the outlet end is arranged so as to be spaced apart from the exterior skin of the aircraft, and the deflector guides the fluid to be drained so that it exits outside a flow boundary layer that is present on the exterior skin. The deflector according to the invention is activated when required and is able to discharge structure-damaging fluids to the environment in such a way that the exterior structure of the aircraft does not become wet, and at the same time the deflector according to the invention, normally accommodated within the contour of the aircraft, does not result in any additional aerodynamic resistance.

  • Patent number: 7651055
    Abstract: A drainmast for discharging fluid from a body in motion, such as an aircraft in flight, may include a barrier disposed at a distal portion of the drainmast. The barrier may extend downstream from the drainmast trailing edge, and may be disposed at a negative angle of attack to a local free-stream airflow, thereby forming a downdraft over the barrier to prevent migration of discharged fluid towards an aircraft skin. In some embodiments, the drainmast may include one or more vanes, disposed internally within a discharge conduit of the drainmast, for deflecting fluid flow within the drainmast towards a direction of free-stream airflow outside the drainmast. Methods for channeling fluid away from an external surface of an aircraft in flight are also disclosed.

  • Publication number: 20100001089
    Abstract: Methods and systems for promoting precipitation from moisture-bearing atmospheric formations are described. A composition comprising a precipitation stimulating material and a volatile liquid agent is located on an aircraft and subject to one or more aircraft-generated pressures during aspersion. A first pressure is a pressure for expelling the composition from the aircraft. A second pressure results from combination between air and aircraft velocity. A third pressure is an ascending pressure resulting from expelling the composition from the aircraft at a lift portion location of the aircraft where only a lift force is applied to the aircraft during flight.
