  • Publication number: 20080271421
    Abstract: A recirculating water extractor includes a swirl vane, a converging nozzle, and two sumps. The recirculating water extractor may be designed to reintroduce uncollected water droplets back into the air stream upstream of both sumps, which may provide additional opportunities for separation. The Coanda effect may be exploited to increase the discharge of water along a surface. Utilizing a converging nozzle may intensify the centrifugal force applied to the air stream rich with entrained water and may move more of entrained water into contact with the wall of the nozzle, which, in turn, may enhance the liquid/vapor separation compared to prior art water extractors. The recirculating water extractor utilizing the Coanda effect and the method for removing entrained water from an air stream may be suitable for, but not limited to, applications in the aircraft and aerospace industries, for example, by being included in environmental control systems of aircraft.

  • Publication number: 20080271427
    Abstract: The present invention is directed to a horizontal rotary cutting system and a method for using such system to cut plant material, such as crops and tall grasses. The axis of rotary motion of the cutting blade is essentially horizontal, i.e., or parallel to the ground and is essentially perpendicular to the longitudinal axis stalk of the plant material to be cut. The cutting blade has an elongated cutting surface that rotates perpendicularly toward, and passes through and cuts the plant material stalks. A cutting diameter of about two inches or less is used to achieve lower horsepower requirements, lower friction losses, and lower vibration of the system when compared to prior systems. High speeds of rotation of the cutting blade permit and facilitate the use of high ground speeds of the cutting system.

    Abstract: An intake air temperature detected by an airflow sensor is corrected based on a rotation speed of an engine and a fuel supply amount to thereby estimate an atmospheric temperature. The atmospheric temperature is estimated by calculating a dynamic temperature error caused by heat generated around an engine and a correction factor in regard to thermal influence which changes according to the flow rate of an intake air, and correcting the intake air temperature detected by the airflow sensor with the temperature error corrected with the correction factor. On the basis of the atmospheric temperature, an electric heater is controlled, which is provided on at least a part of a system of supplying a reducing agent or its precursor, for example, a supply pipe mutually communicating a reducing agent container with a reducing agent supplying apparatus.

  • Publication number: 20080271457
    Abstract: A gas turbine combustor liner, including a shell having a first end adjacent to an upstream end of the combustor and a second end adjacent to a downstream end of the combustor, where the shell also has a hot side, a cold side, and a centerline axis therethrough. A plurality of small, closely-spaced film cooling holes are formed in the shell through which air flows for providing a cooling film along the hot side of the shell. Each cooling hole has a non-uniform diameter as it extends through the shell. In particular, each cooling hole includes a first opening located at the cold side of the shell having a first diameter and a second opening located at the hot side of the shell having a second diameter, wherein the second diameter of the second opening is larger than the first diameter of the first opening. It is preferred that the shape of each cooling hole be substantially frusto-conical.

  • Publication number: 20080271458
    Abstract: A jet impingement array design and method are disclosed for efficiently cooling the liner of a gas turbine combustion chamber, while eliminating almost all effects of coolant gas crossflow. The design includes an array of extended jet ports for which the distance between the ends of the jet ports and the surface to be cooled progressively decreases from upstream to downstream. Spent air from upstream jets is directed away from downstream jets, thereby reducing the detrimental effects of crossflow, and optimizing heat transfer.

  • Publication number: 20080271461
    Abstract: A method of starting a turbine engine at a first engine speed value which is lower than a second engine speed value designed for a normal engine starting operation, comprises varying a fuel flow into a combustor of the engine to start the engine in repeatedly alternating speed acceleration and deceleration cycles in order to create an engine speed augmentation in each of the speed acceleration and deceleration cycles, thereby achieving the second engine speed value while preventing the engine from being overheated, and then beginning the normal engine starting operation

  • Publication number: 20080271464
    Abstract: Embodiments include systems and methods for selectively cooling heat-generating electronic components in an enclosure. According to one embodiment, an enclosure houses a plurality of heat-generating electronic components. Air enters the enclosure at the front and is exhausted at the rear. After passing through one or more upstream components, air diverges into at least first and second airstreams within the enclosure. The first airstream is re-cooled by a cooling system having a thermoelectric cooling module. The thermoelectric cooling module is configured such that a first side is cooled and a second side is heated in response to an applied voltage. A voltage regulator may govern the voltage in response to one or more temperatures sensed within the rack system.

  • Publication number: 20080271465
    Abstract: Disclosed is an air conditioning system for an aircraft which utilizes high pressure bleed air. The bleed air is pressure controlled and introduced into a vortex cooler which can be operated in two modes using a valve. In a first mode, the bleed air is divided into cold and hot streams. The cold stream is directed into the cabin for cooling purposes. The hot stream is released from the aircraft in a manner that it pulls ambient air across a heat exchanger. In a second mode, the bleed air is not divided, but passes through the vortex cooler as a common stream. The second mode is more commonly used in colder ambient air conditions.
