  • Patent number: 11149639
    Abstract: Systems and methods of conditioning inlet air flow in a turbine engine. Where distortions in uniformity of inlet air flow are caused at least in part by the interaction of the air flow with the air inlet duct, a method of adaptively removing the distortions prior to the compressor stage comprises determining the distortion in the airflow; exposing the airflow to a plurality of correction vanes; and positioning the plurality of correction vanes based at least upon the determined distortion. An inlet conditioner system comprises an adaptable conditioning grid located within an air passage; a sensor suite configured to sense a characteristic of the airflow within the air passage; and a control system operably connected to the sensor suite and the adaptable conditioning grid. The control system may be adapted to configure the adaptable conditioning grid based on a sensed characteristic.

    Abstract: Wind funnel and gas combustion turbine systems are disclosed. Air travels through a wind funnel where it is compressed, and then flows into a compression section of a gas turbine that is fueled by a hydrocarbon fuel source such as natural gas. Compressed air from the wind funnel enters the compression section of the gas turbine through one or more air inlets toward multiple rotating turbine blades in an air feed direction having a component normal to air impact surfaces of the turbine blades. In addition to the compressed air from the wind funnel, ambient air may be introduced into the compression section of the gas combustion turbine.

  • Patent number: 11053018
    Abstract: An inlet for a flight vehicle engine, such as for a supersonic or hypersonic engine, includes an internal flow diverter to divert boundary layer flow. The flow diverter is configured to minimize disruption to flow outside the diverted boundary by being configured through use of a flow field that is also used to configure the walls of the inlet. The flow field that is used to configure an inlet-creating shape and a diverter-creating shape has the same flow generator, contraction ratio, compression ratio, mass capture ratio, pressure ratio between entrance and exit, and/or Mach number, for example. The internal diverter may be configured so as to allow arbitrary selection of a leading edge shape for the internal diverter, for example to use a shape that helps avoid radar detection.

  • Patent number: 9702340
    Abstract: A prime mover that is powered by the energy of a fluid is provided. Such a prime mover may include a first fairing, a second fairing spaced apart from the first fairing to define a gap therebetween and a blade assembly mounted on a shaft that extends between the first and second fairings. The first and second fairings each have a curved peripheral edge for directing a fluid into the gap. When the fluid flows into the gap it contacts the blade assembly to thereby rotate the blade assembly about an axis that is defined by the shaft. The prime mover may be mounted on a cell phone tower and used to generate electricity for powering components of the tower and/or for providing electricity to the power grid.

  • Patent number: 9695795
    Abstract: Various aspects of the technology provide for reducing noise and vibration in a pressure exchanger for high pressure fluid handling equipment such as a desalination system, by disposing grooves between a seal surface and a port. The groove reduces a hammer effect in moving high pressure fluid to a low pressure port and moving low pressure fluid to a high pressure port. Reduction in the hammer effect, in addition to reducing noise, reduces vibration that can cause deterioration of high pressure fluid handling equipment.

  • Patent number: 9360030
    Abstract: An assembly of a first element, such as a fan shroud, with a second element, such as an air guide, realized by assembling an elongate thin lip belonging to the second element in an elongate narrow slit formed by the three sides of an elongate planar plate attached in parallel to a planar wall of the first element. The elongate thin lip includes a concave edge and includes, at either side thereof, extended tips, and the elongate slit includes, at either side thereof, areas in which the thickness of the slit is increased, configured to engage with the extended tips of the lip so that the insertion of the lip into the slit begins by inserting the tips into the areas and then continues with gradual insertion of the rest of the concave edge of the lip as the lip is being advanced.

  • Patent number: 9234502
    Abstract: A method for controlling a two-bladed pitchable swept-blade wind turbine in extreme wind conditions is described, wherein when extreme conditions are detected or forecast for the wind turbine, the wind turbine blades are pitched such that they will passively align in a substantially horizontal arrangement. The blades can be yawed such that a tip of one of the wind turbine blades points into the wind direction, resulting in a reduced surface area of the blades exposed to the extreme wind forces. This reduced surface area provides for a reduction in the extreme loads which may be experienced by the wind turbine in such extreme wind conditions.
