摘要： A wind flow sensing system for determining a turbulence of wind flow at a set of different altitudes above a terrain is provided. The wind flow sensing system comprises an input interface configured to receive a set of measurements of radial velocities at line-of-site points above the terrain for each of the altitudes for a set of time steps, and a processor configured to estimate velocity fields for each of the altitudes based on data assimilation of the velocity fields, estimate unbiased horizontal velocities at each of the altitudes and for each time step, determine an average of the unbiased horizontal velocities for a period of time including the set of time steps, and determine, at each of the altitudes, a turbulence based on the unbiased horizontal velocities for each time step and the average of the unbiased horizontal velocity.

摘要： Methods and apparatus for reducing energy consumed by drones during flight are disclosed. A drone includes a housing, a motor, receiver circuitry carried by the housing, and a route manager. The receiver circuitry is to receive airborne drone-generated wind data from an airborne drone located in an area within which a segment of a flight of the drone is to occur. The airborne drone-generated wind data is to be determined by an inertial measurement unit of the airborne drone. The route manager is to generate a route for the flight of the drone based on wind data, the wind data including the airborne drone-generated wind data. The route is to be followed by the drone during the flight. The route manager is to select at least one portion of the route to cause the drone to be at least partially propelled by wind to reduce energy consumed by the drone during the flight.

摘要： A machine is disclosed for wind sensing on sailboats. Wind is important for sailing, but sailboats lean away from the wind when under sail. Vertical wind angles reduce the accuracy of existing anemometers. The cup blades disclosed here do not lose rotation speed when heeling over. Since it is now easy to have a sophisticated chartplotter display on a mobile device in waterproof case even on small boats, this waterproof wind sensor is a wireless “appcessory” that can talk to smartphones, tablets, computers, e-readers and marine electronics. The circuit board is encapsulated and is itself the wind direction arrow. A fluxgate compass on the circuit board provides wind direction. The apparatus is solar-powered, so there is no wiring to install or chafe. This allows a further inventive step for raising the anemometer using the mast track without needing to climb up or lower the mast.

摘要： The present subject matter is directed to systems and methods for detecting rotor asymmetry of a wind turbine. The method includes measuring wind condition at a location downwind of the rotor for a plurality of rotor positions. Another step includes storing the measured wind condition(s) in predetermined wind bins. The method also includes analyzing the stored wind conditions for each of the predetermined wind bins. If a particular wind bin reaches a certain threshold of captured data points, then the method includes determining a variance between each of the stored wind conditions for the predetermined wind bins that have reached the threshold, wherein a variance between any one of the measured wind conditions greater than a predetermined amount is indicative of rotor asymmetry.

摘要： A bearing assembly for an anemometer configured to provide thrust and axial load protection and reduce exposure to potentially degradative debris and/or contaminants. The bearing assembly includes a first shaft and a second shaft and bearings, wherein the bearings are configured to rotate about at least the first shaft while enclosed within a portion of the second shaft. The second shaft is configured to isolate the bearings from any air flow through the anemometer and debris and/or contaminants carried therewith. The bearing assembly further includes a damping member configured to reduce forces imparted upon the bearings, thereby providing protection and preventing premature damage to the bearings from loads.

摘要： In an SOFC stack system, a reformer supplies reformate to the stack. An anode tail gas portion is recycled into the reformer. An inline flowmeter indicates an apparent recycle flow rate. A map of anode tail gas composition as a function of fuel utilization efficiency U, reformer oxygen/carbon ratio O:C, and recycle percentage R is generated on a laboratory test bed at various recycle rates and fuel utilization rates. Compositions are sent through a flowmeter and a Coriolus mass flowmeter provide a Coriolus flow and sensor voltage function across the various compositions and flow rates to create an average curve and an average (reference) voltage at a given flow. A scale factor Z is calculated and used to determine a scaled sensor voltage X for use in an average flow polynomial curve fit equation to calculate tail gas mass flow rate at any flow value indicated by the flow meter.
