What is an aircraft engine nacelle?
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 the purpose of an engine nacelle?
Nacelles serve a variety of purposes including drag reduction and directing airflow for the purposes of engine cooling and use in the combustion reactions inside engines. Nacelles are also used on horizontal axis wind turbines (HAWT).
What is a nacelle on a car?
nacelle in American English (nəˈsel) noun. the enclosed part of an airplane, dirigible, etc., in which the engine is housed or in which cargo or passengers are carried. the car of a balloon.
What is a nacelle meaning?
a streamlined enclosure
Definition of nacelle : a streamlined enclosure (as for an engine) on an aircraft.
What does nacelle mean?
What is a port nacelle?
A nacelle was an outboard engine housing structure on a spacecraft. The nacelles in warp-capable shuttles and starships housed the warp coils of the vessel’s warp drive.
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.
How much do nacelles weigh?
Their nacelles can stretch to over 50-ft long, and weigh up to 300 tons and more depending on the manufacturer and power rating. Most nacelles have common components, such as a hub, rotor, gearbox, generator, inverters, hydraulics, and bearings.
What is nacelle actuation?
Used to position a nacelle translating sleeve to provide reverse thrust to the aircraft. Deployed and stowed using an electric motor commanded by an electronic control box communicating with aircraft computers.
How big is a nacelle?
Nacelle frames span 14.3–16.6 m (47–54 ft.) if made in one piece, a subassembly, or weldment.
What are nacelles and pylons?
A nacelle pylon, also known as a warp pylon or a nacelle strut, was a large support structure that connected a warp nacelle to the hull of a starship. A nacelle pylon housed the systems that directly linked a warp nacelle to a starship’s warp core.
What is the weight of nacelle?
Nacelle is found located at the top of wind turbine and used to house the electricity generator. The approximate weight of the nacelle ranges between 150 and 300 tonnes.
What are the main components of nacelle?
More than half of the total composite volume was directly associated with nacelle components, such as thrust reversers, acoustic liners, cascades, blocker doors, radial drive fairings and cowlings. On some models, aramid fibers (often in the form of dry-fiber belts) were used to reinforce aluminum fan cases.
How do nacelle systems reduce engine noise?
The nacelle systems also play a significant role in reducing engine noise, including the integration of complex acoustic treatment that has been micro-drilled with millions of small holes on the inner composite surfaces, acting as sound traps.

Why use polymer matrix composites in jet engines?
The drive to boost aircraft operating efficiency continues to fuel adoption of polymer matrix composites in jet engines. Fully exposed in this shot, the nacelle components surrounding the General Electric GEnx turbofan engine provide a wide range of opportunities for advanced composites. Source: Olivier Cleynen
