What is the nacelle on an airplane?
A nacelle (/nəˈsɛl/ nə-SEL) is a “streamlined body sized according to what it contains”, such as an engine, fuel, or equipment on an aircraft.
What is a jet engine nacelle?
A nacelle is the part of the wind turbine that consists of a generator, low- and high-speed shafts, gearbox, brake, and control electronics. It is connected to the tower through a yaw control mechanism. There are two shafts located inside the nacelle, that is, low-speed shaft and high-speed shaft.
What is the purpose of nacelles?
The nacelle is the part of the turbine that houses the components that transform the wind’s kinetic energy into mechanical energy to turn a generator that produces electricity.
What are nacelles made of?
Like wind turbine blades, nacelles are typically very large parts made of composite plastics over a light wood core.
What are the components of nacelle?
There are four components of nacelle production: (1) nacelle structural assembly, (2) drivetrain assembly, (3) nacelle electrical assembly, and (4) yaw assembly.
Can 777 pilots fly the 787?
For example, a 777 pilot can complete 787 flight differences training in five days with no full-flight simulator, and the maintenance training Line and Base Course is 50 percent shorter than the 777 course.
Why do some Starfleet ships have 4 nacelles?
From past discussions it’s been theorized that four nacelles would be used in vessels going great distances from starbase support, allowing the ship to switch off and lessen duty cycles.
Why are there 4 warp nacelles?
The Constellation was intended to be very like the Constitution but with longer range. This is the reason for 4 Nacelles – the ship isn’t any faster at warp than a Constitution class but uses her warp drives up at half the pace, allowing for long cruise durations.
What are the 12 parts that make up the nacelle?
Terms in this set (12)
- rotor. catches the wind and spins the main shaft.
- gearbox. converts the rotation of the rotor from 22RPM into 1500RPM for the generator.
- generator. makes usable electricity using magnets and copper wire.
- yaw motor.
- controller.
- anemometer.
- mechanical brake.
- main shaft.
Why do Star Trek ships have nacelles?
Star Trek Timeline [INTERACTIVE] (ENT: “Civilization”) Nacelles were separated from the ship by large pylons, and usually housed a Bussard ramscoop at the fore end, primarily used for collecting hydrogen from space.
What are engine cowlings?
Definition of cowling : a removable metal covering that houses the engine and sometimes a part of the fuselage or nacelle of an airplane also : a metal cover for an engine.
What are the 12 parts of a nacelle?
What is nacelle assembly?
A nacelle /nəˈsɛl/ is a cover housing that houses all of the generating components in a wind turbine, including the generator, gearbox, drive train, and brake assembly.
Why do the 787 wings bend so much?
Allowing the wings to flex improves aerodynamic stability. The aircraft is more streamlined and experiences less drag. It helps provide a smoother ride for passengers and minimize turbulence. The 787 fly-by-wire technology also helps here to automatically raise or lower the wing trailing edge during the cruise.
