The nacelle (/nəˈsɛl/ nə-SELL) 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]

Other uses[edit]


Like many aviation terms, the word comes from French, in this case from a word for a small boat.[4]
