is a wind turbine cover housing that contains all of the generating components, such as the generator, gearbox, drive train, and brake assembly.
On a wind turbine, what is a nacelle?
A wind turbine nacelle is an enclosed housing that houses the generating parts (drivetrain) of the turbine, primarily the generator, gearbox, drivetrain, and brake assembly. From Comprehensive Energy Systems, a publication published in 2018.
What are the five components that make up a wind turbine?
A wind turbine is made up of five basic components and numerous minor components. The base, tower, rotor and hub (containing three blades), nacelle, and generator are the key components.
To meet the needs of each of these elements, specific wind turbine equipment is required for their installation.
Wind turbine foundation
The foundation for onshore wind turbines lies in the ground, but it is hidden by the soil. It is a massive concrete structural block that must hold the entire turbine as well as the forces occurring on it.
The foundation of offshore wind turbines is submerged and not visible. The base floats for offshore turbines far from the sea, yet it has enough bulk to support and sustain the turbine’s weight and any forces applied to it.
Wind energy tower
Most modern turbine towers are built of round steel tubes. A turbine tower should be the same height as the diameter of the circle its blades make as they spin, according to a rule of thumb. The taller the turbine, the more vulnerable it is to high-speed winds. Because the wind is stronger the further we are from the ground (the wind does not have the same speed at different heights).
In a windmill, where is the nacelle located?
Nacelle. The gearbox, low- and high-speed shafts, generator, and brake are all housed in the nacelle, which sits atop the tower. Some nacelles are the size of a home and can weigh more than 4.5 tons for a 1.5 MW geared turbine.
What is the purpose of nacelles?
When injected with highly energetic warp plasma, or plasma created in the warp core by the reaction of deuterium and antideuterium, mediated through an assembly of dilithium crystals, which are nonreactive with antimatter when subjected to high-frequency electromagnetic fields, warp nacelles contain a number of field coils that create a warp field. Plasma transfer conduits connect the warp nacelle to the warp core, transferring plasma from the core to the nacelles. Because the radiation emitted by a nacelle was harmful to living things, it was normally located at a distance from the vessel’s main construction and secured with a pylon.
A Bussard ramscoop is commonly found at the front of Starfleet nacelles, which collects hydrogen for use in power generation.
According to research conducted by the United Federation of Planets, two nacelles are the optimal amount for creating the most efficient warp field and for vessel management. (The Technical Manual for Star Trek: The Next Generation)
The Federation, on the other hand, has fielded warships with only one nacelle, such as the Saladin-class, as well as vessels with three or more nacelles, such as the Federation-class with three nacelles. (Star Fleet Technical Manual) (ST reference)
A variation of the Galaxy-class starship was modified with a third nacelle in the 24th century. (Star Trek: The Next Generation video game: Birth of the Federation; Star Trek: The Next Generation video game: Star Trek Online)
The USS Enterprise-D had been refitted as a Galaxy X-class spacecraft with a third nacelle in an anti-time future. (Star Trek: The Next Generation episode “All Good Things…”)
What is the weight of a wind turbine nacelle?
What is the weight of a wind turbine? The nacelle alone weighs more than 56 tons, the blade assembly more than 36 tons, and the tower itself weighs roughly 71 tons in the GE 1.5-megawatt variant, for a total weight of 164 tons.
What is the definition of a motor nacelle?
A “streamlined body proportioned according to what it contains,” such as an engine, gasoline, or equipment aboard an aircraft, is a “streamlined body sized according to what it contains.” It is sometimes referred to as a pod when it is attached totally outside the airframe by a pylon, in which case it is attached by a pylon or strut and the engine is referred to as a podded engine. A cockpit may be situated in a nacelle rather than a normal fuselage in some situations, such as the standard “Farman” type “pusher” aircraft or the World War II-era P-38 Lightning.
What are the different parts of a nacelle?
Nacelles are manufactured in assembly plants. (1) nacelle structural assembly, (2) drivetrain assembly, (3) nacelle electrical assembly, and (4) yaw assembly are the four components of nacelle manufacture. According to the National Renewable Energy Laboratory’s (NREL) cost study from 2015, the nacelle module accounted for roughly 36% of the entire cost of an on-shore wind generating installation.
