Engines in nacelles on a Boeing 707.

The nacelle ( ) 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.[1]

Popular culture

  • In the Star Trek franchise, it is used to describe the parts of a starship containing the propulsive components of a ship's warp drive.[4]


Like many aviation terms, the word comes from French, in this case from a word for a small boat.[6]
