2321 results about "Nacelle" patented technology

A nacelle (/nəˈsɛl/ nə-SEL) is a housing, separate from the fuselage, that holds engines, fuel, or equipment on an aircraft. In some cases—for instance in the typical "Farman" type "pusher" aircraft, or the World War II-era P-38 Lightning—an aircraft's cockpit may also be housed in a nacelle, which essentially fills the function of a conventional fuselage. The covering is typically aerodynamically shaped.

Special photoelectric nacelle of power patrol unmanned helicopter

ActiveCN101811578AReal-time operationCompact structureAircraft componentsGyroscopeNacelle
The invention discloses a special photoelectric nacelle of a power patrol unmanned helicopter, which comprises an airborne part and a ground part, wherein the airborne part comprises a fixed part which is positioned in the upper part, a rotatable part which is positioned in the lower part and a servo control assembly; the rotatable part comprises a gyroscope stable rotating tower; the fixed part comprises an electronic control cabin; cables between the electronic control cabin and the gyroscope stable rotating tower are connected by a conducting slide ring which can support the gyroscope stable rotating tower to rotate by nx360 degrees; and the airborne part of the photoelectric nacelle is suspended on the helicopter by a vibration reducing device and communicated with a flight control system of the helicopter. The special photoelectric nacelle is a photoelectric task load with compact structure and high performance, can meet the requirement for remote power patrol, has self-stabilizing function and self-tracing function, can shoot a target to be traced from an image in real time, transmit the target to a ground control vehicle by a radio transmission system on an aerial carrier and is convenient for a patrol parson to directly master the scene condition to improve the efficiency of power patrol.

Wind turbine generator, wind turbine generator system, and power generation control method of wind turbine generator

To provide a wind turbine generator, a wind turbine generator system, and a power-generation control method of a wind turbine generator that are capable of improving the power-generation capability and reducing the fatigue load on the windmill. A data accumulation unit 25 sequentially accumulates data sets of a generated output power P during operation of the wind turbine generator, an incoming wind speed Ws estimated on the basis of a wind speed measured at the anemometer, and a wind direction deviation, which is the difference between a wind direction θw measured at the anemoscope and the orientation of the nacelle; statistical analysis of the data accumulated is carried out by an analyzing unit 26; a distribution curve corresponding to the wind direction deviation of the generated output power at each incoming wind speed is determined; the wind direction deviation corresponding to the peak of the distribution curve is set as a correction value θd of the anemoscope; the correction value of the anemoscope for each incoming wind speed is stored in the wind-direction correction table 27; the wind direction Vw measured at the anemoscope is corrected with the correction value θd of the anemoscope for each incoming wind speed Ws; and power-generation control is carried out using the corrected wind direction as a control parameter.
