摘要: An ocean current detection device and method based on double-helix and double-core vibration fiber-optic cable, comprises a double-core fiber-optic cable and a φ-OTDR system; the double-core fiber-optic cable comprises a first and a second optical fiber core, provided symmetrically in the double helix structure. The terminate ends of the first and the second optical fiber core are connected, and the start end of the first or the second optical fiber core is connected with the φ-OTDR system. When measuring the ocean current characteristics in the target sea area, the double-core fiber-optic cable is provided underwater to generate vortex-induced vibration. The φ-OTDR system is provided for emitting laser towards the cable, receiving returned double-core vibration signals, extracting vibration characteristics from the double-core vibration signals to determine ocean current characteristics, including ocean current flow velocity and direction, to improve the detection accuracy.

摘要: A method can include vapor depositing a corrosion resistant coating to internal and external surfaces of a metallic air data probe. For example, vapor depositing can include using atomic layer deposition (ALD). The method can include placing the metallic air data probe in a vacuum chamber and evacuating the vacuum chamber before using vapor deposition. The corrosion resistant coating can be or include a ceramic coating. In certain embodiments, vapor depositing can include applying a first precursor, then applying a second precursor to the first precursor to form the ceramic coating.

摘要: An example system includes a common mode pneumatic event detector to detect a common mode pneumatic event at pitot tubes of an aircraft, a latch, a relay switch in communication with the latch, and a latch controller to set the latch in a first state to cause the latch to output a first latch signal, the relay switch to output a first pressure signal in response to the first latch signal, the first pressure signal based on pressure data from the pitot tubes, and set the latch in a second state to cause the latch to output a second latch signal based on the detection of the common mode pneumatic event. The relay switch is to output a second pressure signal in response to the second latch signal. The second pressure signal includes estimated pressure data.

摘要: An air data probe includes a probe head defining a longitudinal axis between a forward tip and aft base. A port opening is defined in the forward tip. A first conduit is in fluid communication with the port opening to guide fluid flow from the port opening to a first chamber. The first chamber is downstream from the port opening. A second conduit, offset radially and circumferentially from the first conduit, is in fluid communication with the first chamber to guide fluid flow from the first chamber to a second chamber. The second chamber is downstream from the first chamber. The offset between the first and second conduits is configured to prevent particle ingestion from the port opening from entering the second conduit.

摘要: 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.

摘要: A computer implemented method for estimating angles of attack and/or an angle of sideslip of a flying body includes the steps of: providing data or measurements representative of a time derivative of a module of a speed of the flying body with respect to an air; providing data or measurements representative of corresponding projections of coordinate accelerations on a Cartesian reference frame fixed to the flying body; and calculating the angles of attack and/or the sideslip on a basis of an mathematical relationship of the angles of attack and the sideslip with the coordinate accelerations and the time derivative of the module of the speed of the flying body with respect to the air.
