A nacelle (/ n ə ˈ s ɛ l / nə-SEL) is a streamlined container for aircraft parts such as engines, fuel or equipment. [1] When attached entirely outside the airframe, it is sometimes called a pod, in which case it is attached with a pylon or strut and the engine is known as a podded engine . [ 2 ]
A nacelle / n ə ˈ s ɛ l / is a cover housing that houses all of the generating components in a wind turbine, including the generator, gearbox, drive train, and brake assembly. [ 1 ]
The nacelle consists of an inlet, an exhaust nozzle and a cowling which opens for access to the engine accessories and external tubing. The exhaust nozzle may include a thrust reverser . The podded engine is a complete powerplant, or propulsion system, and is usually attached below the wing on large aircraft like commercial airliners or to the ...
The various components of the modern active yaw systems vary depending on the design characteristics but all the active yaw systems include a means of rotatable connection between nacelle and tower (yaw bearing), a means of active variation of the rotor orientation (i.e. yaw drive), a means of restricting the rotation of the nacelle (yaw brake ...
Schematic representation of a gear rim with teeth on the inner side. The gear rim meshes with four yaw drive pinions.. The gear-rim and the pinions of the yaw drives are the components that finally transmit the turning moment from the yaw drives to the tower in order to turn the nacelle of the wind turbine around the tower axis (z axis).
An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub
The gliding ring of the windmill nacelle was made from multiple wooden parts and, despite the old construction techniques, was usually quite level, allowing the nacelle to rotate smoothly around the tower axis. [1] The hybrid yaw bearing system combines the solutions old windmills used. This system comprises multiple removable radial gliding ...
The nacelle also has an innovative anti-ice system that uses a directed flow nozzle concept. Under the Nexcelle joint venture work sharing arrangement, Middle River Aerostructure Systems supplies the nacelle system’s inlet, fan cowls and apron adapter for the Global 7500’s side-fuselage mounted Passport powerplants, while Safran Nacelles ...
