In one embodiment, a method includes determining, by a controller, a first wind pressure associated with a first port of a first probe, determining, by the controller, a second wind pressure associated with a second port of the first probe, and determining, by the controller, a reference wind pressure associated with an end portion of the first probe. The method also includes calculating, by the controller, a first reference differential using the first wind pressure and the reference wind pressure, calculating, by the controller, a first rotational differential using the first wind pressure and the second wind pressure, and calculating, by the controller, an angular coefficient using the first reference differential and the first rotational differential. The method further includes calculating, by the controller, a wind velocity using the first reference differential and the angular coefficient. The wind velocity represents a wind velocity relative to a vehicle.

A gas leak detection system that combines sensor units having an array of sensors that detect natural gas and the volatile organic compounds and variable atmospheric conditions that confound existing gas leak detection methods, a specially designed sensor housing that limits the variability of those atmospheric conditions, and a machine learning-enabled process that uses the wide array of sensor data to differentiate between natural gas leaks and other confounding factors. Multiple low-cost sensor units can be used to monitor gas concentrations at multiple locations across a site (e.g., a well pad or other oil or natural gas facility), enabling the gas leak detection system to model gas leak emission rates in two- or three-dimensional space to reveal the most likely origin of the gas leak.

A wind estimation system for an aircraft includes a first sensor configured to sense a first position associated with an aircraft control component in a wind condition, a second sensor configured to sense a first configuration associated with a rotor system of the aircraft in the wind condition, and at least one controller in communication with at least one of the first sensor or the second sensor. The at least one controller is configured to determine a tip-path-plane angle of the aircraft based on the first position and the first configuration, and determine at least one of a current wind speed or current wind direction based on the tip-path-plane angle.

An anemometer according to the present disclosure includes: a support strut extending in a vertical direction; a rotary member connected to an upper portion of the support strut so as to be rotatable about an axis of the support strut; a swing arm having a proximal end connected to the rotary member and a distal end swingable in the vertical direction; a slider that is slidable along the support strut and is rotatable; a link having one end connected to the swing arm at a position on a more distal end side with respect to the proximal end of the swing arm and having the other end vertically rotatably connected to the slider; a wind receiver provided on at least one of the distal end of the swing arm and the one end of the link and is configured to rotate the rotary member by a wind in a horizontal direction; and a scale attached to a side surface portion of the support strut so as to allow the slider to indicate a wind speed.

Methods, apparatuses, and systems for collecting the installation error of the wind vane are provided. The image of the blades of the wind turbine and the outer rotor of the generator is obtained. It is determined whether the wind vane is aligned with the center line of the wind turbine, according to a relationship between the center line of the wind turbine and the orienting plane of the wind vane in the image. In a case that the wind vane is not aligned with the center line of the wind turbine, the deviation angle between the wind vane and the center line of the wind turbine is calculated, and a direction of the wind vane is corrected according to the deviation angle. Therefore, installation errors of the wind vane are accurately determined and corrected, and accuracy is improved for installation of the wind vane.

In one embodiment, a system includes a vehicle, one or more probes coupled to the vehicle, and a controller. The vehicle is operable to traverse a distance. The one or more probes are operable to measure wind pressure and generate one or more wind pressure measurements. The controller is operable to receive the one or more wind pressure measurements from the one or more probes, determine a wind angle relative to the vehicle using the one or more wind pressure measurements, and determine a wind speed relative to the vehicle using the one or more wind pressure measurements and the wind angle.
